由于 gcc 编译器版本不受支持，Caffe 编译失败 [英] Caffe compilation fails due to unsupported gcc compiler version

问题描述

我为 Caffe 编译而苦恼.可惜我编译失败了.

I struggle with Caffe compilation. Unfortunately I failed to compile it.

步骤我遵循了:

git clone https://github.com/BVLC/caffe.git
cd caffe
mkdir build
cd build
cmake ..
make all

运行 make all 失败并显示以下错误消息:

Running make all fails with the following error message:

尝试解决问题

第一次尝试

简单的解决方案通常是最好的解决方案，因此(如建议 here) 我试图注释掉 /usr/include/host_config.h 中的宏检查 gcc 版本(第 82 行).不幸的是它不起作用并且编译失败:

Attempts to solve the problem

1st try

Simple solutions are often best ones, so (as suggested here) I tried to comment out macro checking gcc version from /usr/include/host_config.h (line 82). Unfortunately it doesn't work and compilation fails badly:

1 catastrophic error detected in the compilation of "/tmp/tmpxft_000069c2_00000000-4_im2col.cpp4.ii".

第二次尝试

我试着跑了:

2nd try

I tried to run:

cmake -D CMAKE_CXX_COMPILER=g++-4.8 ..
make

但它失败了 exactly 相同的错误消息(即使 g++-4.8 应该被接受).

but it fails with exactly the same error message (even though g++-4.8 should be accepted).

我发现 类似问题(虽然与Caffe无关)，我尝试按照接受的答案中的建议解决它.

I've found similar problem (though not related to Caffe) and I tried to solve it as suggested in the accepted answer.

我做了什么:

1. 我运行了 grep -iR "find_package(CUDA" caffe 命令并找到了 Cuda.cmake 文件在 225.
2. 我将 set(CUDA_HOST_COMPILER/usr/bin/gcc-4.8) 添加到 Cuda.cmake，行前行:find_package(CUDA 5.5 QUIET).
3. 我从 build 目录中删除了所有内容并再次运行 cmake 和 make - 使用和不使用 -D CMAKE_CXX_COMPILER=g++-4.8.

1. I've ran grep -iR "find_package(CUDA" caffe command and found Cuda.cmake file which has find_package(CUDA 5.5 QUIET) in line 225.
2. I added set(CUDA_HOST_COMPILER /usr/bin/gcc-4.8) to Cuda.cmake, line before line: find_package(CUDA 5.5 QUIET).
3. I removed everything from build directory and ran cmake and make again - with and without -D CMAKE_CXX_COMPILER=g++-4.8.

不幸的是结果完全一样.Caffe 可能会以某种方式覆盖它 - 我没有弄清楚如何.

Unfortunately result is exactly the same. Caffe probably overwrites it somehow - I didn't figure it out how.

使 VERBOSE=1 2>&1 |grep -i compiler-bindir 什么都不返回.

有趣的是，make VERBOSE=1 打印失败的命令，即:

What's interesting, make VERBOSE=1 prints command that fails, which is:

/usr/bin/nvcc -M -D__CUDACC__ /mydir/caffe/src/caffe/util/im2col.cu -o /mydir/caffe/build/src/caffe/CMakeFiles/cuda_compile.dir/util/cuda_compile_generated_im2col.cu.o.NVCC-depend -ccbin /usr/bin/cc -m64 -DUSE_LMDB -DUSE_LEVELDB -DUSE_OPENCV -DWITH_PYTHON_LAYER -DGTEST_USE_OWN_TR1_TUPLE -Xcompiler ,"-fPIC","-Wall","-Wno-sign-compare","-Wno-uninitialized","-O3","-DNDEBUG" -gencode arch=compute_20,code=sm_21 -Xcudafe --diag_suppress=cc_clobber_ignored -Xcudafe --diag_suppress=integer_sign_change -Xcudafe --diag_suppress=useless_using_declaration -Xcudafe --diag_suppress=set_but_not_used -Xcompiler -fPIC -DNVCC -I/usr/include -I/mydir/caffe/src -I/usr/include -I/mydir/caffe/build/include -I/usr/include/hdf5/serial -I/usr/include/opencv -I/usr/include/atlas -I/usr/include/python2.7 -I/usr/lib/python2.7/dist-packages/numpy/core/include -I/mydir/caffe/include -I/mydir/caffe/build

当我手动添加 --compiler-bindir/usr/bin/gcc-4.8 标志时，它会打印错误:

when I add --compiler-bindir /usr/bin/gcc-4.8 flag manually, it prints error:

nvcc fatal   : redefinition of argument 'compiler-bindir'

这可能与 this 错误报告有关.

which may be related to this bug report.

没注意到--compiler-bindir和-ccbin是同一个选项，后者已经是在上面的命令中设置失败.当我在上述失败的命令中将 -ccbin/usr/bin/cc 更改为 -ccbin/usr/bin/gcc-4.8 时，它成功完成.现在我需要在 Caffe 的 CMake 文件中找到覆盖所有后续 Caffe 的 CMake 中的 -ccbin 的选项.查看 cmake/Cuda.cmake:252:list(APPEND CUDA_NVCC_FLAGS ${NVCC_FLAGS_EXTRA} 似乎是个好方法.

I didn't notice that --compiler-bindir and -ccbin are the same options, and the latter is already set in above command that failed. When I changed -ccbin /usr/bin/cc to -ccbin /usr/bin/gcc-4.8 in above command that failed, it completes successfully. Now I need to find option in Caffe's CMake file that overwrite -ccbin in all subsequent Caffe's CMakes. Looking at cmake/Cuda.cmake:252:list(APPEND CUDA_NVCC_FLAGS ${NVCC_FLAGS_EXTRA} seems to be good way to go.

我怎样才能成功地完成我的编译?任何帮助表示赞赏.

How can I successfully complete my compilation? Any help is appreciated.

相关的 SO 问题:

• host_config.h:不支持的 GNU 版本！不支持高于 4.9 的 gcc 版本.
• CUDA 6.5 抱怨不支持 gcc 4.9 - 怎么办?.

推荐答案

cmake -D CUDA_NVCC_FLAGS="-ccbin gcc-4.8" .. &&make 导致编译成功.

现在出现了另一个问题:链接 Google 的 libgflags 或 libprotobuf 失败可能是因为它是用较新的 gcc 版本编译的，但它是与提出的问题无关.

Now another problem showed up: linking Google's libgflags or libprotobuf fails probably due to fact that it was compiled with newer gcc version but it's not related to asked question.
