Thanks. (It nevertheless breaks at some other point, so it's still useless.) I knew that ppc has never been supported properly, but there was this crazy "clang on ppc tiger" project that just kept going and each version of clang worked slightly better. I just checked and it seems that the author apparently started working for Google in 2015 and there were no commits to llvm/clang forks since 2014. I didn't realize that the project actually "died" in the meantime. >>> clang-mp-3.9 test.c -o test >> ld: library not found for -lto_library >> clang: error: linker command failed with exit code 1 (use -v to see >> invocation) >> >> Any hints about how to fix these issues? > > What's the output of with '-v -Wl,-v'? > clang-mp-3.9 -v -Wl,-v test.c -o test clang version 3.9.1 (tags/RELEASE_391/final) Target: x86_64-apple-darwin10.8.0 Thread model: posix InstalledDir: /opt/local/libexec/llvm-3.9/bin "/opt/local/libexec/llvm-3.9/bin/clang" -cc1 -triple x86_64-apple-macosx10.6.0 -Wdeprecated-objc-isa-usage -Werror=deprecated-objc-isa-usage -emit-obj -mrelax-all -disable-free -disable-llvm-verifier -discard-value-names -main-file-name test.c -mrelocation-model pic -pic-level 2 -mthread-model posix -mdisable-fp-elim -masm-verbose -munwind-tables -target-cpu core2 -target-linker-version 136 -v -dwarf-column-info -debugger-tuning=lldb -resource-dir /opt/local/libexec/llvm-3.9/bin/../lib/clang/3.9.1 -fdebug-compilation-dir /Users/context-osx/app/texlive/svn/Build -ferror-limit 19 -fmessage-length 175 -stack-protector 1 -fblocks -fobjc-runtime=macosx-10.6.0 -fencode-extended-block-signature -fmax-type-align=16 -fdiagnostics-show-option -fcolor-diagnostics -o /var/folders/Qr/QrzZQ3sbHSybp2W5GAvzYU+++TI/-Tmp-/test-afae7b.o -x c test.c clang -cc1 version 3.9.1 based upon LLVM 3.9.1 default target x86_64-apple-darwin10.8.0 ignoring nonexistent directory "/usr/local/include" #include "..." search starts here: #include <...> search starts here: /opt/local/libexec/llvm-3.9/bin/../lib/clang/3.9.1/include /usr/include /System/Library/Frameworks (framework directory) /Library/Frameworks (framework directory) End of search list.
