Output of boost-1.55 build
I tried to compile boost 1.55 on my gentoo system and it the log library failed
with:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.8.2/include/avx2intrin.h: In function
‘_ZN5boost3log11v2_mt_posix3aux20dump_data_wchar_avx2EPKvmRSt13basic_ostreamIwSt11char_traitsIwEE.part.4’:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.8.2/include/avx2intrin.h:737:62: error:
‘__builtin_ia32_psrlwi256’ needs isa option -m32
return (__m256i)__builtin_ia32_psrlwi256 ((__v16hi)__A, __B);
There are a lot more of these lines with other builtin. I've attached the build
log.
To command to reproduce the isse is:
bjam -j3 -q -d+2 --user-config=user-config.jam -sICU_PATH=/usr
--boost-build=tools/build/v2/ --prefix="../boost-1.55-build" --layout=system
threading=multi link=shared --with-log
And the conent of the user-config.jam is (all in one line):
using gcc : 4.8 : g++ : <cflags>"-march=native -O2 -pipe -ggdb
-floop-interchange -floop-strip-mine -floop-block -ftree-loop-distribution

-ftree-loop-linear -flto=5 -fuse-linker-plugin -Wl,-znow -Wl,--sort-common
-Wl,--hash-style=gnu -Wl,--enable-new-dtags" ;
The error occurs under Gentoo (GCC 4.8.2) as well as under OpenSUSE 13.1 (GCC
4.8.1), both systems equipped with Core i7 Sandy Bridge. On an older AMD Athlon
X2 with Ubuntu 14.04 I get an internal compiler error instead of the wrong isa
error.
Please let me know if you need further information.
