Hi LLVM Team, It's my first mail to the maillist, and if there's something I misdo, please let me know. What I am doing is: 1. build llvm with `--enable-optimized` and `--enable-profiling` 2. my command-line configuration is: `../llvm/configure --prefix="/opt/llvm_optimized_profiling/" --enable-optimized --enable-profiling --enable-cxx11` My Problem is: 1. It triggered a link-time error. 2. Error message is: llvm[4]: Linking Release+Profile+Asserts executable c-index-test /files/Install/LLVM_Framework/build_optimized_profiling/Release+Profile+Asserts/lib/libclang.so: undefined reference to `clang::format::getLLVMStyle()' /files/Install/LLVM_Framework/build_optimized_profiling/Release+Profile+Asserts/lib/libclang.so: undefined reference to `clang::format::reformat(clang::format::FormatStyle const&, clang::Lexer&, clang::SourceManager&, std::vector<clang::CharSourceRange, std::allocator<clang::CharSourceRange> >)' collect2: error: ld returned 1 exit status make[4]: *** [/files/Install/LLVM_Framework/build_optimized_profiling/Release+Profile+Asserts/bin/c-index-test] Error 1 make[4]: Leaving directory `/files/Install/LLVM_Framework/build_optimized_profiling/tools/clang/tools/c-index-test' make[3]: *** [all] Error 1 make[3]: Leaving directory `/files/Install/LLVM_Framework/build_optimized_profiling/tools/clang/tools' make[2]: *** [all] Error 1 make[2]: Leaving directory `/files/Install/LLVM_Framework/build_optimized_profiling/tools/clang' make[1]: *** [clang/.makeall] Error 2 make[1]: Leaving directory `/files/Install/LLVM_Framework/build_optimized_profiling/tools' make: *** [all] Error 1 Notes: 1. I have also built an debug version with: `../llvm/configure --prefix="/opt/llvm_debug/" --enable-cxx11`, and there was no error. 2. I have also built an release version with `../llvm/configure --prefix="/opt/llvm_optimized/" --enable-optimized --enable-cxx11`, and there was no error. -- Adam Basfop Cavendish Shanghai University Leader of Shanghai University Open Source Community Phone: 13761283909 E-mail: GetbetterABC at Yeah.net Address: 99 Shangda Rd., Shanghai University, Baoshan District, Shanghai, China [上海宝山区上大路99号(近南陈路) 校内5号楼] -------------- next part -------------- An HTML attachment was scrubbed...
