[LLVMdev] newbie llc build problem: BreakCriticalEdges.cpp:44: undefined reference to `llvm::LoopSimplifyID'
Hi, Looking into LLVM for a database query engine project... After downloading the latest source from CVS, it's my first time trying to build LLVM. Following the "Getting Started" instructions, all went well until gmake reported this error while trying to link llc: In function `(anonymous namespace)::BreakCriticalEdges::getAnalysisUsage(llvm::AnalysisUsage&) const': /home/kh/llvm.cvs/llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp:44: undefined reference to `llvm::LoopSimplifyID' collect2: ld returned 1 exit status gmake[2]: *** [/home/kh/llvm/obj/Debug/bin/llc] Error 1 AFAICT, 'LoopSimplifyID' does in fact appear to be present in libLLVMScalarOpts.a, and that library does appear to be specified in the linker command line displayed by gmake. What should I do to solve the link error?

To fix this, I moved the loopsimplify pass from the Scalar library to the utils library. Please do the following: 1. cd lib/Transforms 2. cvs up -P -d 3. cd Utils; make clean 4. cd Scalar; make clean Then rebuild. Hopefully LLC will build now. If not, please send in the error message. Thanks for reporting the problem! People who haven't hit this problem shouldn't need to do the steps above: normal update and builds should be fine. -Chris> ++++++++++++++ Configuration: Red Hat Enterprise Linux 4 - x86 - GCC 3.4.3 >
