[Mono-dev] Link errors with mono-llvm

[Zoltan Varga]

Hi,

  Make sure you are using the 'master' branch of the mono llvm repo. Also,
try using --with-llvm=<prefix> instead of --enable-llvm=yes, the latter
might pick up the system version of llvm. Otherwise, I don't know what is
causing the problem, those symbols are in libraries which are supposed to
be linked into the mono executable, i.e.:
mini/Makefile should contains something like:

LLVM_LIBS = -lLLVMX86CodeGen -lLLVMX86Desc -lLLVMX86Info
-lLLVMMCDisassembler -lLLVMX86AsmPrinter -lLLVMX86Utils -lLLVMSelectionDAG
-lLLVMAsmPrinter -lLLVMMCJIT -lLLVMRuntimeDyld -lLLVMObject -lLLVMMCParser
-lLLVMBitReader -lLLVMJIT -lLLVMExecutionEngine -lLLVMCodeGen
-lLLVMScalarOpts -lLLVMInstCombine -lLLVMTransformUtils -lLLVMipa
-lLLVMBitWriter -lLLVMAnalysis -lLLVMTarget -lLLVMMC -lLLVMCore
-lLLVMSupport -L/Users/vargaz/git/llvm/usr64/lib  -lz -lpthread -ledit
-lcurses -lm  -lstdc++
