We've run into a problem building log. It doesn't appear to be a known issue and we're not sure how to work around it. We found a hack to make our builds succeed, but there may well be a better workaround and we're not certain whether there are any issues with what we've done.
We tried to build Boost 1.55 with GCC 4.8.1, 4.8.3, and 4.9.1 with the following commands:
./bootstrap.sh --prefix=<prefix> --libdir=<prefix>/lib --with-toolset=gcc
./b2 --build-type=complete --layout=versioned 'cxxflags=-m64 -O2 -g -pipe' 'cflags=-m64 -O2 -g -pipe' 'linkflags=-Wl,-rpath -Wl,<prefix>/lib -L/lib64 -Wl,-rpath -Wl,/lib64 -m64' -d+2 -j3
./b2 --build-type=complete --layout=versioned 'cxxflags=-m64 -O2 -g -pipe' 'cflags=-m64 -O2 -g -pipe' 'linkflags=-Wl,-rpath -Wl,<prefix>/lib -L/lib64 -Wl,-rpath -Wl,/lib64 -m64' -d+2 -j3 install
The errors we get come from this command during the build:
gcc.compile.c++ bin.v2/libs/log/build/gcc-4.9/release/link-static/log-api-unix/threading-multi/dump_avx2.o "g++11" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -pthread -fno-strict-aliasing -ftemplate-depth-1024 -m64 -O2 -g -pipe -march=core-avx2 -mavx -mavx2 -fabi-version=0 -m64 -O2 -g -pipe -DBOOST_ALL_NO_LIB=1 -DBOOST_CHRONO_STATIC_LINK=1 -DBOOST_FILESYSTEM_STATIC_LINK=1 -DBOOST_LOG_BUILDING_THE_LIB=1 -DBOOST_LOG_USE_NATIVE_SYSLOG -DBOOST_LOG_WITHOUT_EVENT_LOG -DBOOST_SPIRIT_USE_PHOENIX_V3=1 -DBOOST_SYSTEM_NO_DEPRECATED -DBOOST_SYSTEM_STATIC_LINK=1 -DBOOST_THREAD_BUILD_LIB=1 -DBOOST_THREAD_DONT_USE_CHRONO=1 -DBOOST_THREAD_POSIX -DBOOST_THREAD_USE_LIB=1 -DDATE_TIME_INLINE -DNDEBUG -I"." -c -o "bin.v2/libs/log/build/gcc-4.9/release/link-static/log-api-unix/threading-multi/dump_avx2.o" "libs/log/src/dump_avx2.cpp"
There are many lines of output; I've elided similar messages to highlight the unique ones:
{standard input}: Assembler messages:
{standard input}:611: Error: operand type mismatch for `vpsrldq'
...
{standard input}:819: Error: no such instruction: `vextracti128 $0x1,%ymm2,%xmm2'
...
{standard input}:1087: Error: no such instruction: `vextracti128 $0x1,%ymm3,48(%r15)'
...
{standard input}:1312: Error: operand type mismatch for `vpaddb'
While there might be a way to actually get b2 to disable AVX2 support, we hacked libs/log/build/Jamfile.v2 with these commands:
sed -i 's:dump_avx2::g' libs/log/build/Jamfile.v2
sed -i 's:<define>BOOST_LOG_USE_AVX2::g' libs/log/build/Jamfile.v2
Those remove dump_avx2 from BOOST_LOG_COMMON_AVX2_SRC and remove the definition of BOOST_LOG_USE_AVX2, which prevents compiling enable_avx2().
Is there a better way to solve or work around this problem?
