Hi,
I’ve posted a similar question a few days ago, but didn’t get a satisfying reply (Thanks Jan). Maybe this time…
I’m trying to build a simple program which uses clang libs on linux with g++.
After failing at the linking phase using the llvm-config --ldflags --libs script, I’ve tried to copy-paste the output of the script directly into the g++ command, but unfortunately I still get an enormous amount of “undefined refernce to…” error messages.
What am I doing wrong? Please see the build output below:
