Hi, For the last week or so my combined llvm+clang+lldb build fails while linking lldb-gdbserver:
lib/liblldbHost.a(Host.cpp.o): In function `lldb_private::Host::RunShellCommand(char const*, char const*, int*, int*, std:: __1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >*, unsigned int, bool)': /home/abuild/rpmbuild/BUILD/llvm/stage2/../tools/lldb/source/Host/common/Host.cpp:578: warning: the use of `mktemp' is dang erous, better use `mkstemp' lib/liblldbExpression.a(ClangExpressionParser.cpp.o): In function `ClangExpressionParser': /home/abuild/rpmbuild/BUILD/llvm/stage2/../tools/lldb/source/Expression/ClangExpressionParser.cpp:127: undefined reference to `llvm::sys::getDefaultTargetTriple()' lib/liblldbExpression.a(ClangExpressionParser.cpp.o): In function `lldb_private::ClangExpressionParser::Parse(lldb_private: :Stream&)': /home/abuild/rpmbuild/BUILD/llvm/stage2/../tools/lldb/source/Expression/ClangExpressionParser.cpp:315: undefined reference to `llvm::sys::fs::createTemporaryFile(llvm::Twine const&, llvm::StringRef, int&, llvm::SmallVectorImpl<char>&)' /home/abuild/rpmbuild/BUILD/llvm/stage2/../tools/lldb/source/Expression/ClangExpressionParser.cpp:311: undefined reference to `llvm::sys::fs::createUniqueFile(llvm::Twine const&, int&, llvm::SmallVectorImpl<char>&, unsigned int)' /home/abuild/rpmbuild/BUILD/llvm/stage2/../tools/lldb/source/Expression/ClangExpressionParser.cpp:339: undefined reference to `llvm::MemoryBuffer::getMemBufferCopy(llvm::StringRef, llvm::Twine const&)' tools/lldb/tools/lldb-gdbserver/CMakeFiles/lldb-gdbserver.dir/__/__/source/lldb.cpp.o: In function `lldb_private::Initializ e()': /home/abuild/rpmbuild/BUILD/llvm/stage2/../tools/lldb/source/lldb.cpp:130: undefined reference to `llvm::install_fatal_erro r_handler(void (*)(void*, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, bool), void* )' [lots of similar errors] This seems to be due to failing to link to LLVMSupport library which could be fixed by --- lldb/cmake/LLDBDependencies.cmake +++ lldb/cmake/LLDBDependencies.cmake @@ -161,6 +161,7 @@ set( LLVM_LINK_COMPONENTS mcdisassembler executionengine option + support ) but then I hit more undefined symbols elsewhere. So I am wondering if I am the only one hitting this error. Regards, ismail
