Description

How can I configure windows in order for my Golang client to work ? e.g. where should I place librdkafka client ?

How to reproduce

download librdkafka from https://www.nuget.org/packages/librdkafka.redist/ & unzip its contents
go get -u github.com/confluentinc/confluent-kafka-go/kafka
setup pkg-config for windows
go run main.go results in

Package rdkafka was not found in the pkg-config search path.
Perhaps you should add the directory containing `rdkafka.pc'
to the PKG_CONFIG_PATH environment variable
No package 'rdkafka' found
pkg-config: exit status 1

@ligoo / @rwsegura , I was getting seg faults and other strange behavior, so I decided to explore generating the .a file myself instead of renaming the .lib from the NuGet package. If anyone is curious, this is a high level overview of how you do it

pacman -S mingw-w64-x86_64-tools-git
gendef librdkafka.dll
dlltool -k -l librdkafka.a -d librdkafka.def

I'm having success with confluent-kafka-go v1.4.2 and librdkafka v1.4.2 this way

@neptoess This is great news! I will try out your solution as soon as possible. At the moment, I just dev under 1.3.0 on windows and benchmark with 1.4.2 on ubuntu. @rwsegura I guess you did something similar to @neptoess. Thanks for the answer

@ligoo - Sorry for the long delay.

I had two .h files that I made changes to were rdkafka.h and rdkafkacpp.h

@iradul

I am getting this error message:

go get -u gopkg.in/confluentinc/confluent-kafka-go.v1/kafka
go: finding github.com/confluentinc/confluent-kafka-go/kafka/librdkafka latest
go: finding github.com/confluentinc/confluent-kafka-go/kafka latest
go: downloading github.com/confluentinc/confluent-kafka-go v1.4.2
go: extracting github.com/confluentinc/confluent-kafka-go v1.4.2
# runtime/cgo
exec: "x86_64-w64-mingw32-gcc": executable file not found in %PATH%

I followed exactly all the steps and all things goes well, but when I tried this command: go get -u gopkg.in/confluentinc/confluent-kafka-go.v1/kafka I got the error above.

Any fix please ?

@neptoess Thank you for your answer !

I get away from using Cygwin, and decided to use Mingw64 alone, but unfortunately I am getting this errors:

I already copied the files from nuget to mingw folders like so:

copy from the NuGet package downloaded from https://www.nuget.org/packages/librdkafka.redist/ (version 0.11.4) librdkafka.redist.0.11.4\build\native\include\librdkafka\rdkafka.h => C:\mingw64\include\librdkafka\rdkafka.h

(Since I was getting error related to:

# gopkg.in/confluentinc/confluent-kafka-go.v1/kafka

 #include <sys/socket.h> /* for sockaddr, .. */

)

Modify C:\mingw64\include\librdkafka\rdkafka.h and replace #ifdef _MSC_VER by #ifdef __MINGW64__(2 times)
Copy from the NuGet package librdkafka.redist.0.11.4\build\native\lib\win\x64\win-x64-Release\v120\librdkafka.lib =>C:\mingw64\lib\librdkafka.a

Any help on this please ?

Thank you !

@bcashier , Try with the v1.4.2 NuGet package. Also make sure you look at my other two comments. For v1.4.2, you have to modify rdkafka.h and 00version.go in the pkg directory (the ones go mod downloads)

@neptoess

I added the line to 00version.go, but in the commented code, or should I put it before the commented code ?

@bcashier You have it in the right spot. The errors you're seeing are coming from the linking step, so librdkafka.a is probably where the issue lies. You said you used librdkafka.redist 0.11.4, but I've only tested this with the latest (v1.4.2). I would recommend updating your files to those, but do the gendef / dlltool thing instead of using the .lib from the NuGet package.

@neptoess

I just switched to the version 1.4.2, and I got this error:

# gopkg.in/confluentinc/confluent-kafka-go.v1/kafka
c:/ming64/bin/../lib/gcc/x86_64-w64-mingw32/6.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lrdkafka
collect2.exe: error: ld returned 1 exit status

And generated the librdkafka.a using your method !

Any advice please ?

Big thanks again for your time :)

You followed these steps and copied to your mingw64 lib folder? gendef librdkafka.dll dlltool -k -l librdkafka.a -d librdkafka.def

Yes I just did that sir :)

And the file is generated successfully !


C:\Users\...\librdkafka.redist.1.4.2\runtimes\win-x64\native> gendef librdkafka.dll
 * [librdkafka.dll] Found PE+ image

C:\Users\...\librdkafka.redist.1.4.2\runtimes\win-x64\native> dlltool -k -l librdkafka.a -d librdkafka.def

ld --verbose | grep SEARCH_DIR Do that and make sure librdkafka.a is in one of those folders (hint: ls FOLDER | grep kafka)

Since grep method not present on Windows, I just copied all the response from: ld --versbose command

==================================================

And something is sure, I don't have SEARCH_DIR folders !

/c/mingw610/ ...

My mingw folder is: C:/ming64 and already added the bin folder inside it to the ENV VARIABLES.

Highly recommend using msys2 (https://www.msys2.org/) and installing all your MinGW packages through the provided pacman tool. I'm sure you can get your MinGW install working as well, but I haven't worked with it directly, solely through msys2. You can do a quick test C program and try compling with, e.g. gcc -o a.exe mytest.c -lrdkafka

@neptoess

I followed your method by installing msys64 and it was compiled successfully !

And reproduced all the steps from here: https://github.com/confluentinc/confluent-kafka-go/issues/128#issuecomment-639672311

And also generated my own .a file using dlltool (I used my mingw64 version for GENDEF since it wasn't found in the msys64 version of mingw).

Thank you sir !

@bcashier For future reference pacman -S mingw-w64-x86_64-tools-git will install gendef

Thanks @iradul, I went throught the sames step (some step are missing but it's still quite good)

But on the last one it won't build, any idea?

I followed through alll the steps but I am also having same issue. I can see the file socket.h in sys folder. Were you or anyone able to resolve this issue?

@PriAggarwal If you’re using cygwin, I would make sure that your PATH has gcc resolve to the cygwin one.

If you would rather use MinGW, you can follow my instructions on this issue.

For anyone still interested in this, librdkafka v1.4.4 was released, and this version builds under MinGW. To make confluent-kafka-go more friendly, we’ll need to create and bundle kafka/librdkafka/librdkafka_windows.a and kafka/build_windows.go. This will involve a few minor changes to librdkafka. I won’t have time to get to this in the immediate future, but I can help anyone out who’s willing to take on the work (it’s not a ton of code, I would guess maybe 5-10 lines?)

@neptoess I keep getting the following error even after all the steps you provided:

github.com/confluentinc/confluent-kafka-go/kafka C:/TDM-GCC-64/bin/../lib/gcc/x86_64-w64-mingw32/9.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lrdkafka collect2.exe: error: ld returned 1 exit status

I was able to do all the step without any issues and the librdkafka.a file is in the directory also:

18325@DGUS-SSUN MINGW64 /c/users/18325/.nuget/packages/librdkafka.redist/1.5.0/runtimes/win-x64/native $ ls /mingw64/lib | findstr kafka librdkafka.a

Any help would be appreciated!

@stephenwsun , Aside from moving over to MSYS2 for your MINGW64 environment, you can try running this command to see where ld is looking for libraries ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012

@neptoess @edenhill thanks for all the help! I was able to get this working with the latest versions (confluent-kafka-go v1.4.2 and librdkafka v1.5.0). These are the steps I took:

Windows

Download the MSYS2 installer (msys2-x86_64-20200720.exe) here. The default installation folder should be C:\msys64 and the rest can be set to defaults.
After installation, the MSYS shell should be running. If not, then launch it.
Run the following command:
```
pacman -Syu
```
Proceed with installation and press enter when prompted to close the MSYS window.
Open MSYS shell again.
Run the following command again:
```
pacman -Syu
```

Then run the following command:

pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-pkg-config

Edit environment variables, and add the following to your user variables Path:
```
Add C:\msys64\mingw64\bin to your path
```
Open Visual Studio, and open Package Manager.
Install librdkafka.redist v1.5.0 with the following command:
```
Install-Package librdkafka.redist -Version 1.5.0
```

Copy the following file from the NuGet package:

C:\Users\18325\.nuget\packages\librdkafka.redist\1.5.0\build\native\include\librdkafka\rdkafka.h

And place in librdkafka directory (create the directory if it doesn't exist):
```
C:\msys64\mingw64\include\librdkafka\rdkafka.h
```
Modify the rdkafka.h file and replace the following:

Line 58:
```
#ifdef _MSC_VER
```
With:
```
#ifdef __MINGW64__
```
Line 2025:
```
#ifndef _MSC_VER
```
With:
```
#ifndef __MINGW64__
```
In the confluent-kafka-go package, modify 00version.go file:

Above #include <librdkafka/rdkafka.h>, add the following line:
```
#cgo LDFLAGS: -lrdkafka
```
Copy the rdkafka.pc file in the root directory and paste in the following directory:
```
C:\msys64\mingw64\lib\pkgconfig
```
Add the following DLLs from the NuGet package to C:\Windows\System32:
```
librdkafka.dll, librdkafkacpp.dll, libzstd.dll, zlib.dll
```
Open MSYS shell.
Run the following command:
```
pacman -S mingw-w64-x86_64-tools-git
```
Run the following command:
```
gendef librdkafka.dll
```

Run the following command:

dlltool -k -l librdkafka.a -d librdkafka.def

Run the following command to see where ld is searching for libraries:
```
ld --verbose | findstr SEARCH_DIR | tr -s ' ;' \\012
```
Copy generated librdkafka.a file to your mingw64 lib folder
Use go run . or go build to create executable.

@stephenwsun , Good job! Glad to see you got it working. I've finally gotten around to throwing some code together and opening a PR (https://github.com/confluentinc/confluent-kafka-go/pull/509), so hopefully we'll get this down to just your first 8 steps on Windows (with a few more packages in the pacman command) soon!

@stephenwsun I follow the step by step to the end , i got this error :

ld.exe: skipping incompatible E:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../libmingwthrd.a when searching for -lmingwthrd

....

my confluent-kafka-go version is 1.4.2

I don't know which step is wrong.

Any help would be appreciated!

@i542873057 If this isn't a production application or anything, you can try to use the source branch of this PR (https://github.com/confluentinc/confluent-kafka-go/pull/509). As long as you have MinGW installed and in path, this should work fine with no extra steps (a Windows static library is bundled)

I'm always getting this error:

./librdkafka/rdkafka.h:83:10: fatal error: sys/socket.h: No such file or directory

Most steps, as outlined by @stephenwsun and others, (but I added a couple probably unnecessary steps in attempts to fix it) work, but something basic must be wrong.

@EugenDueck Not sure why you’re replacing _WIN32 with MINGW32. rdkafka.h should not require any modification as long as it’s from v1.4.2 or newer.

Might also want to go into your go\pkg\mod...\00version.go file and add

cgo windows LDFLAGS: -lrdkafka above the #include for rdkafka.h

Thanks @neptoess

Not sure why you’re replacing _WIN32 with MINGW32. rdkafka.h should not require any modification as long as it’s from v1.4.2 or newer.

I tried this because I got the sys/socket.h not found error, which meant _WIN32 was not set at the time rdkafka.h was included. As the error is still there, however, my replacing it does not seem to have fixed anything.

Might also want to go into your go\pkg\mod...\00version.go file and add #cgo windows LDFLAGS: -lrdkafka above the #include for rdkafka.h

Doing that already - it's (plainly hidden) in this line:

D:\a\1\s\confluent-kafka-go>powershell -Command "(gc kafka\00version.go) -replace '#include <librdkafka/rdkafka.h>',"""#cgo LDFLAGS: -lrdkafka`n#include <librdkafka/rdkafka.h>""" | Out-File -encoding ASCII kafka\00version.go"

@EugenDueck

I got exactly the same error. The way I fixed it is that I found it didn't use the file "rdkafka.h" in "msys64\mingw64\include\librdkafka" folder, instead it used the "rdkafka.h" in kafka-confluent package ("go\pkg\mod\github.com\confluentinc\confluent-kafka-go@v1.4.2\kafka\librdkafka"). You first find "00version.go", then find the "librdkafka" directory in the same folder, the file "rdkafka.h" is in that folder. I changed this file, then it worked.

The following is the error I got. It tell you that the file it used is "./librdkafka/rdkafka.h", the path is relative to "00version.go".

github.com/confluentinc/confluent-kafka-go/kafka

In file included from D:\code\pkg\mod\github.com\confluentinc\confluent-kafka-go@v1.4.2\kafka\00version.go:24: ./librdkafka/rdkafka.h:83:10: fatal error: sys/socket.h: No such file or directory 83 | #include <sys/socket.h> / for sockaddr, .. / | ^~~~~~ compilation terminated.

@jfeng45 Thanks - that looks like a promising route to take indeed.

In the meantime, due to having wasted so much time on trying to cross-compile confluent-kafka-go, and another problem I have with it - namely, it silently not delivering all the messages that I send, with no errors in the events channel, and after supposedly successful flushing), I decided to cut my losses. I am now happily using and cross-compiling sarama. But if I will in fact get back to giving confluent-kafka-go another try, this may be the first thing to try!

@stephenwsun thanks! I got it worked successfully with your instructions. Except I don't have to change your #13 "Modify the rdkafka.h file and replace the following"

Hi, guys. I'm also trying to build this in Windows. Luckily I do not have much troubles. I have read the responses above, and find that the solutions above is to add dynamic libraries to the system load path (maybe C:\Windows\System32). My solution is described below:

Install MinGW I installed MinGW with scoop (as well as nuget), run scoop install https://raw.githubusercontent.com/ScoopInstaller/Main/ccc24e57b6026f88d5a7b1c11150e83487a016e1/bucket/gcc.json, and gcc 8.1.0 will be installed. ~The latest gcc (9.3.0) remains untried.~ Yes it could build.
Install Nuget, and run nuget install librdkafka.redist. The version of the library is v1.6.0.
Add github.com/confluentinc/confluent-kafka-go v1.5.2 to go.mod, then run go mod tidy.
Add CGO_LDFLAGS. I run this command in git bash, just modify the user home path or use ~ or $whoami. Use similar methods to add this flag in PS or WT.
```
CGO_LDFLAGS="-LC:\Users\Administrator\.nuget\packages\librdkafka.redist\1.6.0\runtimes\win-x64\native -lrdkafka" go build
```
The binary will be successfully generated, but it needs those dynamic libraries to run. Copy dll files in C:\Users\Administrator\.nuget\packages\librdkafka.redist\1.6.0\runtimes\win-x64\native to the path and it should run normally.

main.go

package main

import (
    "fmt"

    "github.com/confluentinc/confluent-kafka-go/kafka"
)

func main() {
    vnum, vstr := kafka.LibraryVersion()
    fmt.Printf("LibraryVersion: %s (0x%x)\n", vstr, vnum)
}

Before copy

$ ./first.exe
C:/Users/Administrator/go/src/example/first/first.exe: error while loading shared libraries: librdkafka.dll: cannot open shared object file: No such file or directory

After copy

$ ./first.exe
LibraryVersion: 1.6.0 (0x10600ff)

@edenhill I followed the solution which you suggested here, but during go build getting an undefined reference error. please help on this

@AswathyAshokan , There's a lot in information in this comment section, but those errors are because you aren't linking to rdkafka.

@neptoess How i can link this rdkafka package in golang. Can you give any useful document for this?

-lrdkafka needs to be passed to the C compiler. The way that happens with Go is through the #cgo directive. As I mentioned in https://github.com/confluentinc/confluent-kafka-go/issues/128#issuecomment-704518971, I currently do this in the 00version.go file

@neptoess I added

cgo windows LDFLAGS: -lrdkafka

#include <librdkafka/rdkafka.h>

to 00version.go but still getting the same error.

I'm not really sure how to provide much further support. You can try making a quick test app in C and seeing if you're able to link to rdkafka. You're using TDM-GCC though. There are a few sets of instructions in this comment thread for how to get everything working under MSYS2. This is just hard because we're using dynamic linking.

Hopefully, at some point in the future, this PR (https://github.com/confluentinc/confluent-kafka-go/pull/564) gets merged, as it would bundle a static rdkafka for Windows. You can point your Go project to the source repo/branch of that PR and see if it works for you.

@neptoess I can able to build after taking source code from PR . I think you will merge this PR in nearer future.. Thank You for your support

For anyone still following this, #564 was merged, so the next release of confluent-kafka-go will include a static bundle for Windows (librdkafka_windows.a). It should work seamlessly for anyone with MinGW gcc installed.

For anyone still struggling to get target windows/amd64 successfully built on linux, I have managed to make it work with the help of this comment.

I'm using Ubuntu 20.04 LTS, I had to apt install mingw-w64 first.

After that all I needed was some env variables and one ldflags parameter to make it static (might not even be necessary but it works for me so I use it)

env \
  GOOS=windows \
  GOARCH=amd64 \
  CGO_ENABLED=1 \
  CC=x86_64-w64-mingw32-gcc \
  CXX=x86_64-w64-mingw32-g++ \
  CGO_CXXFLAGS="-IC:\msys64\mingw64\include" \
go build -ldflags '-extldflags "-static"'

I'm not exactly sure what's happening with all the vars but I believe the Go utilizes mingw-w64 to build all the necessary libraries that aren't available for windows in this package, such as librdkafka.

@EugenDueck

I got exactly the same error. The way I fixed it is that I found it didn't use the file "rdkafka.h" in "msys64\mingw64\include\librdkafka" folder, instead it used the "rdkafka.h" in kafka-confluent package ("go\pkg\mod\github.com\confluentinc\confluent-kafka-go@v1.4.2\kafka\librdkafka"). You first find "00version.go", then find the "librdkafka" directory in the same folder, the file "rdkafka.h" is in that folder. I changed this file, then it worked.

@jfeng45 How to change the file "rdkafka.h", Can you tell me it in detail
