http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=3114086 The key with this error is "unrecognized command line option '-m64'" but that tells me that boost isn't actually using the proper distro CFLAG options because if it was it was it would not fail as the distro flags automatically provide the optimal flags for each architecture gcc.compile.c++ serial/boost/bin.v2/libs/atomic/build/gcc-5.1.1/release/debug-symbols-on/pch-off/python-2.7/threading-multi/lockpool.o "g++" -g -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fno-strict-aliasing -pthread -fPIC -m64 -DBOOST_ALL_NO_LIB=1 -DBOOST_ATOMIC_DYN_LINK=1 -DBOOST_ATOMIC_SOURCE -DNDEBUG -I"." -c -o "serial/boost/bin.v2/libs/atomic/build/gcc-5.1.1/release/debug-symbols-on/pch-off/python-2.7/threading-multi/lockpool.o" "libs/atomic/src/lockpool.cpp" cc1plus: error: unrecognized command line option '-m64'
This should be fixed already in boost-1.58.0-4.fc24, could you try another build please?
The problem is not that boost isn't using the distro CFLAGS, it is using them, but that Boost's own build system adds additional flags to the compiler commands, and for GCC it always adds either -m32 or -m64. The latest versions in f23 and rawhide has a patch to prevent that being added.
OK, koji-shadow builds in order so I'm going to have to spend time to override that process
OK, built now
