I try build ldc master branch with llvm clone from https://github.com/ldc-developers/llvm.git

get this error,  not sure where I am doing wrong, there link command seems not correct:

some how the $LINK_LIBRARIES is set to "-lclang: -lcd -l&& /usr/bin/clang -fomit-frame-pointer -pipe -O0 -L/opt/local/bin/../lib -lphobos2-ldc -ldruntime-ldc -ldl -lpthread -lm -m64"

how should I fix this ?

I find the issue and fixed it,  because I use a shell to proxy ldc for debug, so the ExtractDMDSystemLinker get the extra symbols.
