bindings/go: error "No rule to make target fdb_c_options.g.h"

[uh-zuh]

As mentioned there: https://github.com/apple/foundationdb/tree/master/bindings/go I run only one command and get error:

> ./fdb-go-install.sh install --fdbver 6.3.15

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

I try it in Ubuntu 18.04 LTS on Windows.

fdb_c_options.g.h is part of fdb_c. This is fixed on master branch. To bypass this problem, you can build fdb_c first, and then do the go install.

I have the same issue. I can't find the right instructions to build fdb_c and get this fdb_c_options.g.h file. Can you point me into the right direction @jzhou77 please?

[damienleroux]

I tried the master branch and I have the same problem.

Does anyone succeed in bypassing this?

Where can I find fdb_c_options.g.h?

🙏

edit: I found another way to get it. I installed the client package:

mkdir /etc/resource
wget https://www.foundationdb.org/downloads/6.3.18/ubuntu/installers/foundationdb-clients_6.3.18-1_amd64.deb -P /etc/resource/
sudo dpkg -i /etc/resource/foundationdb-clients_6.3.18-1_amd64.deb
ls /usr/include/foundationdb/
# fdb.options  fdb_c.h  fdb_c_options.g.h

I have same problem with fdb 7.1.36 on macOS 13.4.1 (a)

mkdir build
cd build

This is how fdb_c_options.g.h is generated (copied from build.ninja file).

We usually compile insider build docker image with command like CC=clang CXX=clang++ LD=lld cmake -S ${HOME}/src/foundationdb -B ${HOME}/cbuild_output -D USE_LD=LLD -D USE_WERROR=ON -D USE_LIBCXX=1 -G Ninja && ninja -C ${HOME}/cbuild_output

vexillographer.exe is compiled from C# code:

# Custom command for vexillographer.exe

build vexillographer.exe | ${cmake_ninja_workdir}vexillographer.exe: CUSTOM_COMMAND /root/src/foundationdb/fdbclient/vexillographer/c.cs /root/src/foundationdb/fdbclient/vexillographer/cpp.cs /root/src/foundationdb/fdbclient/vexillographer/java.cs /root/src/foundationdb/fdbclient/vexillographer/python.cs /root/src/foundationdb/fdbclient/vexillographer/ruby.cs /root/src/foundationdb/fdbclient/vexillographer/vexillographer.cs

Thanks @jzhou77, but it doesn't work, I'm on a Mac Studio M2, the docker image is only for amd64 :(

Error response from daemon: manifest for foundationdb/build:latest not found: manifest unknown: manifest unknown
Unable to find image 'foundationdb/build:latest' locally

How do you go about developing layers in Go on macOS?

I find it really difficult to use the go client.

I trying to generate ninja file:
