What is your question?

Hi, I am trzing to use a RESTinio pkg using conan2.4. the pkg has build successfully but when I call the basic helloworld main.cpp file I got following error

`fatal error: restinio/core.hpp: No such file or directory

include <restinio/core.hpp>

Have you read the CONTRIBUTING guide?

Hi @FaiqueAli

It seems that you are not defining the build_type=Debug in your host profile or command line, but then you are doing later a -DCMAKE_BUILD_TYPE=Debug build. I think this would fix the issue.

Also, it is not clear how the Conan toolchain is being used, you are not using the Conan toolchain, generated with CMakeToolchain, like -DCMAKE_TOOLCHAIN=.../conan_toolchain.cmake but your own toolchain, but then the -- Conan messages of the conan_toolchain.cmake are printed on the output, so that looks good, but cannot be fully sure.

FaiqueAli commented 1 week ago

Hi thanks for prompt rep, I have updated the host profile also with build_type=Debug but still getting same error.. Regarding conantoolchain.cmake I am not sure how to use it. I read article for cross compilation I need a toolchain, therefore I found this toolchain from QNX and trying to use this. it will be great if you could guid me how can I use conantoolchain.cmake.

Thanks :)

The conan_toolchain.cmake is intended to be used as the main toolchain for most cases, check https://docs.conan.io/2/tutorial/consuming_packages/build_simple_cmake_project.html

If you have a user toolchain that you want to add, it is possible to inject it with something like tools.cmake.cmaketoolchain:user_toolchain=[your_toolchain.cmake], you might find this example useful: https://docs.conan.io/2/examples/tools/cmake/cmake_toolchain/inject_cmake_variables.html

memsharded commented 1 week ago

A few things:

The toolchains cannot be included as:

include("${CMAKE_BINARY_DIR}/Debug/generators//conan_toolchain.cmake")

They need to be passed in command line arguments (or from using CMake presets file)

Then, you shouldn't be doing:

include_directories ("/home/username/.conan2")
include_directories ("/home/username/.conan2/p/resti2478711f40029/p/include/restinio")

The include directories are already defined in the targets, so restinio::restinio will contain it. Harcoding such a path as above, that might even change in different machines would be broken.

Similar with

set(llhttp_DIR "${CMAKE_BINARY_DIR}/Debug/generators/")

It shouldn't be necessary. It is specially bad, as it is hardcoding a Debug path, but the configuration might be Release.

We can start from something that works, for example:

$ conan new cmake_lib -d name=mypkg -d version=0.1 -d requires="restinio/[*]"
# add ``#include "restinio/core.hpp"`` in the src/mypkg.cpp source file
$ conan build . -s compiler.cppstd=17  # My default is 14, it might not be necessary in your case

This doesn't fail, and the mypkg CMakeLists is just:

cmake_minimum_required(VERSION 3.15)
project(mypkg CXX)

find_package(restinio CONFIG REQUIRED)

add_library(mypkg src/mypkg.cpp)
target_include_directories(mypkg PUBLIC include)

target_link_libraries(mypkg PRIVATE restinio::restinio)

That is the find_package() + target_link_libraries is enough to find the header correctly.

FaiqueAli commented 1 week ago

So after updating my profile settings from Debug to Release, conan generated a Release folder instead of Debug, thats expected. making changes in Cmakelist.txt file, it looks like


cmake_minimum_required(VERSION 3.10)

project(QNX-restinio-app)

set(llhttp_DIR "${CMAKE_BINARY_DIR}/Release/generators/")
set(fmt_DIR "${CMAKE_BINARY_DIR}/Release/generators/")
set(expected-lite_DIR "${CMAKE_BINARY_DIR}/Release/generators/")
set(asio_DIR "${CMAKE_BINARY_DIR}/Release/generators/")
set(restinio_DIR "${CMAKE_BINARY_DIR}/Release/generators/")

find_package(fmt REQUIRED)
find_package(llhttp REQUIRED)
find_package(expected-lite REQUIRED)
find_package(asio REQUIRED)
find_package(restinio CONFIG REQUIRED)

add_executable(QNX-restinio-app main.cpp)
add_library(QNX-restinio-app main.cpp)
target_include_directories(QNX-restinio-app PUBLIC include)

target_link_libraries(QNX-restinio-app fmt::fmt)
target_link_libraries(QNX-restinio-app llhttp::llhttp)
target_link_libraries(QNX-restinio-app asio::asio)
target_link_libraries(QNX-restinio-app nonstd::expected-lite)
target_link_libraries(QNX-restinio-app PRIVATE restinio::restinio)
#target_link_libraries(QNX-restinio-app ${CONAN_LIBS})

set_property(TARGET ${PROJECT_NAME} PROPERTY CXX_STANDARD 17)

after that I executed the command in the terminal, that you mentioned..

$ conan new cmake_lib -d name=QNX-restinio-app -d version=0.7.2 -d requires="restinio/[*]"

did I understood correctly ?

# add ``#include "restinio/core.hpp"`` in the src/mypkg.cpp source file it is already included in the main.cpp file

please let me know if I am doing sth wrong..

memsharded commented 1 week ago

QNX-restinio-app

Note that Conan 2 does not allow package names with upper case. So this will fail the moment you try to create the package, please use lowercase names only.

Furthermore, it is also typical to not name apps based on the OS, the app is myapp, and you can build it for qnx, but you might also build it for Linux-gcc normal native application.

compiler=qcc

It seems you have changed your default profile, instead of defining a specific qcc profile.

Often, it is very useful to test things, specially proof of concepts, and setups, with the standard native system. And define specific technologies profiles in their own files. Note that profiles can also be managed with conan config install to shared them in developer teams, and ensure that CI machines also have the same configuration.

add #include "restinio/core.hpp" in the src/mypkg.cpp source file

This is not possible, if you created the template I am talking about with conan new cmake_lib those lines will not be there.

ERROR: Missing prebuilt package for 'fmt/10.2.1'. You can try:

This is expected, as your profile is using qcc, ConanCenter does not have binaries for qnx, so they need to be built from source. The error message is suggesting to use --build=missing to build them.

FaiqueAli commented 1 week ago

ah ok, Now I changed the name of the app to qnxrestinio. Second I added #include "restinio/core.hpp" in the src/qnxrestinio.app file.

you mean I should also include --build missing parameter into $ conan build . -s compiler.cppstd=17 --build missing command ? so I also included that, so the command sequence is as below..

conan install .. --build missing  --profile:build=default --profile:host=aarch64
conan new cmake_lib -d name=qnxrestinio -d version=0.7.2 -d requires="restinio/[*]"
conan build . -s compiler.cppstd=17  --build missing

but at the end I got list of errors like below..

conan install .. --build missing  --profile:build=default --profile:host=aarch64
conan new cmake_lib -d name=qnxrestinio -d version=0.7.2 -d requires="restinio/[*]"
conan build . -s compiler.cppstd=17  --build missing

It seems you are mixing 2 different things here. The first conan install .. is completely independent of the other 2 commands. With the conan new + conan build I am trying to provide a fully reproducible and testable example, independent of your code, to illustrate that things work, and that most of those things in your CMakeLists.txt are not necessary.

So lets work with only:

conan new cmake_lib -d name=qnxrestinio -d version=0.7.2 -d requires="restinio/[*]"
conan build . -s compiler.cppstd=17  --build missing

Lets have it building first for the native Linux system, for example. Then, we can try to add the qnx profile and see what happens:

conan build . --profile:host=aarch64  --build missing

Still, this second conan build is working with the code generated by cmake_lib, not your other code.

Otherwise, the other possible way to proceed would be:

The goal of this process is "divide and conquer", try to eliminate possible causes, until the reason of not finding the headers can be understood.

FaiqueAli commented 1 week ago

So you mean, I dont need to use conan install now,

my command sequence at the terminal is 

$ conan new cmake_lib -d name=qnxrestinio -d version=0.7.2 -d requires="restinio/[*]"
$ conan build . --profile:host=default  --build missing

default is the current OS profile (build environment Linux) output of conan build 

======== Input profiles ========
Profile host:

Profile host:

Profile build:

but at the end I got

memsharded commented 1 week ago

Yes, the restinio.h doesn't exist. Sorry my instructions were not complete, the complete isntructions were in my comment above and are:

$ conan new cmake_lib -d name=mypkg -d version=0.1 -d requires="restinio/[*]"
# add ``#include "restinio/core.hpp"`` in the src/mypkg.cpp source file
$ conan build . -s compiler.cppstd=17  # My default is 14, it might not be necessary in your case

default is the current OS profile (build environment Linux)

There is something that I might be missing? Is that as special Linux box? How was that profile defined? Conan doesn't define that default profile, because it doesn't have the qcc compiler detection in the default profile detection. So I guess that such a profile was defined by other means.

I am trying to use first a more native, standard compiler as gcc, to first sort out possible set-up issues. And then when it works, move to qcc, because the qcc setup could have different challenges, for example, some ConanCenter dependencies might not work or fail to build with qcc, but that is a different issue. So we need to isolate problems, start with gcc first, then move to qcc later.

FaiqueAli commented 1 week ago

I already tested restinio package with gcc compiler for host and target as linux, and that is working absolutely fine.

I use conan profile detect command to create default profile, and for target profile I just created a text file inside conan profile folder. Now, I deleted all profile txt files and recreated a default profile using the command connan profile detect. I only have one default profile which I edited acoordingly, after that I again executed the commands sequence as below.

If you reached out that point, then the error:

ERROR: Missing prebuilt package for 'fmt/10.2.1'. You can try:
    - List all available packages using 'conan list "fmt/10.2.1:*" -r=remote'
    - Explain missing binaries: replace 'conan install ...' with 'conan graph explain ...'
    - Try to build locally from sources using the '--build=fmt/10.2.1' argument

Means that you don't have a binary built for fmt for those settings. I am not fully sure how you got the rest, I guess they were built in some of your previous commands?

The error message is suggesting to do --build=xxx or you can also do --build=missing to fire the build of fmt from source for your current profile, please try that and let us know.

FaiqueAli commented 1 week ago

No, until now I am not able to build fmt/10.2.1 I think here comes the problem that I am not able to build fmt for QNX. I also tried with $ conan build . -s compiler.cppstd=17 --build missing and $ conan build . -s compiler.cppstd=17 --build=fmt/10.2.1 and is generating list of errors 

error: 'PTHREAD_MUTEX_RECURSIVE' was not declared in this scope
   __ec = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE);

which I mentioned is my previous comments..

memsharded commented 1 week ago

Ok, understood, it seems that we are doing some progress. The initial report was about 

/path/main.cpp:5:10: fatal error: restinio/core.hpp: No such file or directory
#include <restinio/core.hpp>
^~~~~~~~~~~~~~~~~~~
compilation terminated.

It is possible that fmt doesn't build with that qcc version 4.4? fmt is using pretty modern C++, so maybe if qcc is not very compliant to that latest C++ standard, it might not work. Do you know if that version of fmt can be used with qcc 4.4 compiler?

Recipes in ConanCenter has common validate() rules for the mainstream compilers, if you try to use an older gcc for example, the recipe might raise an error telling that a more modern compiler would be needed. But they won't include validation for other compilers.

Likewise, Conan 2 strongly recommends the definition of compiler.cppstd in your profile, with your desired C++ standard. This will help recipes to diagnose and raise errors if that provided standard is not enough to use that recipe.

The compiler.cppstd is also automatically added by the conan profile detect, have you removed it for some specific reason? I'd recommend to add it and try again, please try that and let me know. Thanks!

FaiqueAli commented 1 week ago

Yes atleast now it is not complaining about restinio.h

I also noticed that the profile is showing qcc version 4.4 while compiling fmt, and I dont understand how can I change this. on the other hand in conan profile I provided the qcc version 8.3.

now I also have added the compiler.cppstd=gnu14 in profile but still same error.

memsharded commented 1 week ago

All your profiles output above are displaying:

compiler.version=4.4

So it doesn't seem to be reading that profile you say that defines 8.3 version.

By the way, in order to even reduce the reproduction to that last failure, I think it should be reproducible with:

conan install --requires=fmt/10.2.1 --build=missing -pr=myqnxprofile

That should be good enough to trigger the same error. Can you please share the output of that command with the updated gnu14 and qcc 8.3?

conan install --requires=fmt/10.2.1 --build=missing -pr=default

Sorry, this is not making any sense. It seems that you have a pre-compiled binary for this package, for qcc. But ConanCenter doesn't have this binary for sure, so it means that you have built this binary yourself before, without issues?

Please try to remove your package first conan remove fmt* -c and try again, and provide again the full log, or try to force the build with --build="fmt/*" instead of the build=missing.

include "restinio.h"

Sure it fails, the restinio.h doesn't exist. You need to replace it by the restinio/core.hpp above, please see the above comments.

Hi @memsharded, Could you please check my last steps and the outcome thanks :)

FaiqueAli commented 6 days ago

So as an update, I have change the build command with conan build . --build=missing -pr:h=aarch64 by removing -s compiler.cppstd=17 flag and now I am getting some other errors, rather than PTHREAD_MUTEX_RECURSIVE and now the list of errors are 

conan build . --build=missing  -pr:h=aarch64

Hi @memsharded, still waiting for your feedback..

memsharded commented 5 days ago

At this point I tend to think that qcc 8.3 doesn't have the necessary C++17 support to compile fmt. Is this possible?

Can you please try to build and use fmt without Conan with your compiler?

memsharded commented 5 days ago

By the way, I have been trying to find information about qcc 8.3, its standard support, any issues, etc, but the documentation and occurrences seem really scarce. It is also not listed in https://en.cppreference.com/w/cpp/compiler_support

Maybe you have some links or pointers to places to look up this information?

FaiqueAli commented 4 days ago

@memsharded thanks for the identification of suspected cause, I will try to build fmt with qcc, meanwhile I will also try to get the information regarding qcc compiler support for c++17 standard and let you know..

by the way at the moment without adding the parameter compiler.cppstd=17 in the command I am getting the following error

looks like qcc supports c++17, have a look at this link

Can you please try to build and use fmt without Conan with your compiler?

I have tried fmt with qcc but getting some other errors not related to c++17.

I am doubtful with these warnings also.

From the above:

include <sys/sendfile.h>

It seems we passed the error of building fmt, with qcc if I understood correctly, but it is a bit difficult to understand because dealing with a large application, not something minimal that we can reproduce.

It seems this is something not related to fmt anymore, but to the setup of the qcc toolchain, and some information to locate "system" qcc headers is missing somewhere. I don't have enough knowledge about qcc.

Is it possible to download a free version of qcc from somewhere to try things?

Then, if possible, the best would be really to put everything in a Github repo, with a build.py script in its root with the exact reproduction steps so we can use that to check.

Yes, I also think its not related to fmt, rather to qcc tool-chain. I don't think that qcc have free version is available.
what about the warnings that I have highlighted.

what about the warnings that I have highlighted.

The warnings are expected, those recipes from ConanCenter still have some legacy code that needs to be removed.
