[LLVMdev] clang looking for gold plugin when used with '-emit-llvm' option
Are you intending to try to link? That error message isn't coming from clang, but from /usr/bin/ld. If you just want the bitcode for the one source file, you need to pass "-c" as well, just like if you want an object file. -Jim On May 16, 2012, at 5:39 PM, Ashok Nalkund <ashoknn at qualcomm.com> wrote:> Resending, can somebody please help?

MY BAD (in caps)...really sorry to have bothered. I was thinking of -S -E options but forgot the -c option. clang -c -emit-llvm test.c lli test.o both work fine :).

[LLVMdev] clang looking for gold plugin when used with '-emit-llvm' option
No worries. That's a much easier thing to fix than a bug in the tools! FWIW, the error message is effectively saying that your system linker isn't set up to do LLVM link-time-optimization (which uses bitcode object files). That's probably normal, just a horrid error message. -Jim On May 16, 2012, at 6:08 PM, Ashok Nalkund <ashoknn at qualcomm.com> wrote:> MY BAD (in caps)...really sorry to have bothered.
