Trying to install llvm-3.9.1-r1 with abi_x86_32 fails due to what seems to me to be a typo (-std=c*+11 instead of -std=c++11). Relevant portion of the build log: * abi_x86_32.x86: running multilib-minimal_abi_src_install >>> Working in BUILD_DIR: "/var/tmp/portage/sys-devel/llvm-3.9.1-r1/work/llvm-3.9.1.src-abi_x86_32.x86" [1/60] Building CXX object lib/Transforms/Scalar/CMakeFiles/LLVMScalarOpts.dir/LoopRotation.cpp.o [2/60] Linking CXX shared library lib32/libLLVMScalarOpts.so.39.1 [3/60] Creating library symlink lib32/libLLVMScalarOpts.so.39 lib32/libLLVMScalarOpts.so [4/60] Building CXX object lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/TargetPassConfig.cpp.o FAILED: lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/TargetPassConfig.cpp.o /usr/bin/x86_64-pc-linux-gnu-g++ -m32 -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -Ilib/CodeGen -I/var/tmp/portage/sys-devel/llvm-3.9.1-r1/work/llvm-3.9.1.src/lib/CodeGen -Iinclude -I/var/tmp/portage/sys-devel/llvm-3.9.1-r1/work/llvm-3.9.1.src/include -DNDEBUG -march=corei7-avx -O2 -pipe -fPIC -fvisibility-inlines-hidden -Wall -W -Wno-unused-parameter -Wwrite-strings -Wcast-qual -Wno-missing-field-initializers -pedantic -Wno-long-long -Wno-maybe-uninitialized -Wdelete-non-virtual-dtor -Wno-comment -Werror=date-time -std=c*+11 -ffunction-sections -fdata-sections -fPIC -MD -MT lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/TargetPassConfig.cpp.o -MF lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/TargetPassConfig.cpp.o.d -o lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/TargetPassConfig.cpp.o -c /var/tmp/portage/sys-devel/llvm-3.9.1-r1/work/llvm-3.9.1.src/lib/CodeGen/TargetPassConfig.cpp x86_64-pc-linux-gnu-g++: error: unrecognized command line option ‘-std=c*+11’ [5/60] Linking CXX shared library lib32/libLLVMipo.so.39.1 [6/60] Building CXX object lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/TargetSchedule.cpp.o ninja: build stopped: subcommand failed.
