/usr/bin/ld: cannot find -lclang when building irony-server

I've been trying to build irony-server, at the start I had problems related with not being able to find the libclang libraries, but now it fails when it tries to link:

I've searched and found related problems but their solutions didn't work ( they where also different programs ) : Clang-complete Crystal-lang

Thanks in advance.

Yay! Fixed! Thanks to this awesome post in stack-exchange : running ld in verbose mode. Long story short: if you open ld in verbose mode you can see where does it try to open libclang.so So the only thing i had to do was locate libclang.so To find where my libclang.so was, then i simply symlinked it! sudo ln -s /usr/lib/llvm-3.8/lib/libclang.so /usr/lib/libclang.so

Hope this helps someone with the same (dumb) problem! :)

Any ideas, why this symlink is not defaulting in Ubuntu?
