This is happening on my sparc64 non multilib box I haven't tested elsewhere. Reproducible: Always Steps to Reproduce: 1. Get access to a sparc box 2. emerge any clang ebuild Actual Results: Calculating dependencies... done! emerge: there are no ebuilds to satisfy "~sys-devel/llvm-9999[clang(-),debug=,multitarget?,python?,static-analyzer,abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?]". (dependency required by "sys-devel/clang-9999-r100::gentoo" [ebuild]) Expected Results: clang should build on sparc it is even supposed to be self hosting on sparc64.
please paste the complete output of emerge -pv clang and emerge --info.

I suppose you have both =sys-devel/clang-9999-r100 and =sys-devel/llvm-9999 in your package.unmask ? Also clang USE-flag is masked on sparc, did you also unmask it? Else I don't really have an idea right now, maybe the portage team will have one By the way, llvm is keyworded on sparc, but not clang. If it works fine now (on a release), it could be worth a keywording bug
I recommend to verify that the USE settings are sane, using a command like this: emerge -pv --nodeps llvm clang
(In reply to Zac Medico from comment #5) > I recommend to verify that the USE settings are sane, using a command like > this: > > emerge -pv --nodeps llvm clang LLVM is already installed with USE="debug doc gold libffi multitarget ncurses static-analyzer ". VIDEO_CARDS="radeon" also as I was experimenting with building mesa on here. I should have mentioned that before. leafblower ~ # emerge -pv --nodeps llvm clang These are the packages that would be merged, in order: [ebuild R *] sys-devel/llvm-9999:0/9999::gentoo USE="debug doc gold libffi multitarget ncurses static-analyzer (-clang) (-libedit) -lldb -ocaml -python {-test} -xml" PYTHON_TARGETS="python2_7 (-pypy)" VIDEO_CARDS="radeon" 0 KiB [ebuild N *] sys-devel/clang-9999-r100:0/9999::gentoo USE="static-analyzer -debug -multitarget -python" 0 KiB Total: 2 packages (1 new, 1 reinstall), Size of downloads: 0 KiB
(In reply to Chase Rayfield from comment #6) > [ebuild R *] sys-devel/llvm-9999:0/9999::gentoo USE="debug doc gold > libffi multitarget ncurses static-analyzer (-clang) (-libedit) -lldb -ocaml > -python {-test} -xml" PYTHON_TARGETS="python2_7 (-pypy)" > VIDEO_CARDS="radeon" 0 KiB This shows that the clang flag is masked, and the message in comment #0 shows that it is needed. You can unmask it like this: mkdir -p /etc/portage/profile echo -clang >> /etc/portage/profile/use.mask
Also, you shouldn't use USE=debug. It means a lot of trouble.
I removed the debug flag earier... and it currently fails during attempting to build llvm-9999 when applying the clang-0001-Install-clang-runtime-into-usr-lib-without-suffix.patch So I am attempting with a release version of llvm.
For some reason LLVM 3.6.2 crashes during the emerge... so I just did: ebuild llvm-3.6.2.ebuild merge then I emerged clang 3.6.2-r100 and put this in /etc/portage/env/clang CC="clang -target sparc-unknown-linux-gnu" CXX="clang++ -target sparc-unknown-linux-gnu" CFLAGS="-O2 -pipe" CXXFLAGS="${CFLAGS}" then setup an htop to build with clang in packages.env and it just works mostly I had to override the CFLAGS because it barfs on -cpu=niagra and also I believe it needs to have the target passed to it. Other than spewing a bunch of warnings about ignoring soft float it builds htop just fine. When attemting to rebuild llvm with clang I get: checking whether Clang will select a modern C++ standard library... no configure: error: We detected a missing feature in the standard C++ library that was known to be missing in libstdc++4.6 and implemented in libstdc++4.7. There are numerous C++11 problems with 4.6's library, and we don't support GCCs or libstdc++ older than 4.7. You will need to update your system and ensure Clang uses the newer standard library. Does that mean I need to emerge @system or @world with a newer compiler Than gcc 4.6? I did build clang itself with gcc 5.2. ldd `which clang` libLLVM-3.6.so => /usr/bin/../lib/libLLVM-3.6.so (0xf5c78000) libpthread.so.0 => /lib/libpthread.so.0 (0xf5c34000) libstdc++.so.6 => /usr/lib/gcc/sparc-unknown-linux-gnu/5.2.0/libstdc++.so.6 (0xf5aa8000) libgcc_s.so.1 => /usr/lib/gcc/sparc-unknown-linux-gnu/5.2.0/libgcc_s.so.1 (0xf5a84000) libc.so.6 => /lib/libc.so.6 (0xf5904000) libz.so.1 => /lib/libz.so.1 (0xf58dc000) libffi.so.6 => /usr/bin/../lib/libffi.so.6 (0xf58c0000) libncurses.so.5 => /lib/libncurses.so.5 (0xf5864000) libdl.so.2 => /lib/libdl.so.2 (0xf5850000) libm.so.6 => /lib/libm.so.6 (0xf576c000) /lib/ld-linux.so.2 (0xf7a94000)
This one's really old. Please retry with 7.0.1, and open a new bug if it still doesn't work. However, please note that I don't have any sparc hardware, so you'll probably need to figure it out yourself and provide a patch.
