[FR] Compiling Firebase on Ubuntu 18.04 + Clang 6.0 compiler

Open Jaisiero opened this issue 4 years ago • 7 comments

[REQUIRED] Please fill in the following fields:

  • Pre-built SDK from the website or open-source from this repo: commit f0a9d5b65e3a014aee347ea9bb3b664cdce2ae55
  • Firebase C++ SDK version: v6.16.0
  • Main Firebase Components in concern: All available
  • Other Firebase Components in use: All available
  • Platform you are using the C++ SDK on: Desktop Ubuntu 18.04
  • Platform you are targeting: Desktop Linux

[REQUIRED] Please describe the question here:

Hi there,

I'm trying to compile Firebase for Desktop Linux target and I did it at first running this CMake configuration on my Ubuntu 18.04 distro like:

cmake ../../.. -DPROTOBUF_SRC_ROOT_FOLDER:PATH="/home/jaisiero/Documentos/Repos/FBLinux/protobuf-3.12.0" -DPROTOBUF_PROTOC_EXECUTABLE:FILEPATH="/home/jaisiero/Documentos/Repos/FBLinux/protoc-3.12.0-linux-x86_64/bin/protoc" -DNANOPB_SOURCE_DIR:PATH="/home/jaisiero/Documentos/Repos/FBLinux/nanopb-0.4.4-linux-x86" -DBUILD_TESTING=OFF -DCMAKE_POSITION_INDEPENDENT_CODE=ON -D_GLIBCXX_USE_CXX11_ABI=0 -DPYTHON_LIBRARY:PATH=/usr/lib/python3.6/config-3.6m-x86_64-linux-gnu/libpython3.6.so -DPYTHON_EXECUTABLE:FILEPATH=/usr/bin/python3.6 -DPYTHON_INCLUDE_DIR:PATH=/usr/include/python3.6

and it worked! I was able to compile Firebase libraries with my default GCC distro buuut I'm trying to link them with another libraries compiled with libc++ and as a result I'm having some link issues. Consequently, I try to compile with Clang running this CMake configuration getting this include error:

cmake ../../.. -DPROTOBUF_SRC_ROOT_FOLDER:PATH="/home/jaisiero/Documentos/Repos/FBLinux/protobuf-3.12.0" -DPROTOBUF_PROTOC_EXECUTABLE:FILEPATH="/home/jaisiero/Documentos/Repos/FBLinux/protoc-3.12.0-linux-x86_64/bin/protoc" -DBUILD_TESTING=OFF -DCMAKE_POSITION_INDEPENDENT_CODE=ON -DPYTHON_LIBRARY:PATH=/usr/lib/python3.6/config-3.6m-x86_64-linux-gnu/libpython3.6.so -DPYTHON_EXECUTABLE:FILEPATH=/usr/bin/python3.6 -DPYTHON_INCLUDE_DIR:PATH=/usr/include/python3.6 -DCMAKE_CXX_COMPILER="/usr/bin/clang++" -DCMAKE_C_COMPILER="/usr/bin/clang" -DCMAKE_EXE_LINKER_FLAGS="${CMAKE_EXE_LINKER_FLAGS} -stdlib=libc++ -lc++abi" -DCMAKE_THREAD_LIBS_INIT="-lpthread" -DCMAKE_HAVE_THREADS_LIBRARY=1 -DCMAKE_USE_WIN32_THREADS_INIT=0 -DCMAKE_USE_PTHREADS_INIT=1 -DTHREADS_PREFER_PTHREAD_FLAG=ON

I see in the official webpage that Firebase can be compile with Clang 5.0 on Ubuntu:

Firebase CPP SDK Setup

I'm currently using Clang 6.0.

I'm pretty sure it's a silly mistake and i hope someone could help me.

Cheers, Jaime.

I found a few problems with this issue:

  • I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
  • This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @Jaisiero,

I'm not sure off the top of my head what the issue would be based on the error I'm seeing. The error message gives you to other files to look into that have additional diagnostic information:

-- Configuring incomplete, errors occurred!
See also "/home/jaisiero/Documentos/Repos/FBLinux/firebase-cpp-sdk/out/build/destktop_linux64_build/CMakeFiles/CMakeOutput.log".
See also "/home/jaisiero/Documentos/Repos/FBLinux/firebase-cpp-sdk/out/build/destktop_linux64_build/CMakeFiles/CMakeError.log".

Take a look at those and see if they clarify what exactly is causing the failure.

alexames avatar Jan 07 '21 23:01 alexames

Hey @alexames ,

Sure! Here you are:

CMakeError.log CMakeOutput.log

It's full of errors :S

It seems Cmake is not finding:

-lc++abi not found

but I installed clang in my distribution (Ubuntu 18.04) just like that:

sudo apt install clang

Thank you for helping, Jaime.

Jaisiero avatar Jan 11 '21 10:01 Jaisiero

Taking a look at the log, it seems to have not only link error but also compiler error like

/home/jaisiero/Documentos/Repos/FBLinux/firebase-cpp-sdk/out/build/destktop_linux64_build/CMakeFiles/CMakeTmp/CheckIncludeFiles.c:2:10: fatal error: 'winsock2.h' file not found
#include <winsock2.h>
         ^~~~~~~~~~~~
/home/jaisiero/Documentos/Repos/FBLinux/firebase-cpp-sdk/out/build/destktop_linux64_build/CMakeFiles/CMakeTmp/CheckSymbolExists.c:27:19: error: use of undeclared identifier 'strnicmp'; did you mean 'strncmp'?
  return ((int*)(&strnicmp))[argc];
                  ^~~~~~~~
                  strncmp

I suspect that the source might not be compatible to Clang 6.0.

Let me ping the team and see if we have more insight about it.

chkuang-g avatar Jan 14 '21 03:01 chkuang-g

Does it work if you disable LevelDB build test using -DLEVELDB_BUILD_TESTS=OFF?

chkuang-g avatar Jan 14 '21 19:01 chkuang-g

Naaah, It doesn't work either.

CMakeError.log CMakeOutput.log

Firebase c++ sdk says:

Firebase docs

Linux libraries For Linux, library versions are provided for 32-bit (i386) and 64-bit (x86_64) platforms.

Note that the Linux libraries were tested using GCC 4.8.0, GCC 7.2.0, and Clang 5.0 on Ubuntu.

When building C++ desktop apps on Linux, link the pthread system library to your project. Consult your compiler documentation for more information. If you're building with GCC 5 or later, define -D_GLIBCXX_USE_CXX11_ABI=0.

However, you might be right and the source is not compatible with this compilator anymore or maybe I'm doing something wrong.

Thanks for your time, Jaime.

Jaisiero avatar Jan 15 '21 19:01 Jaisiero

I'll put this as a feature request to support Clang 6.0+.
