Bug 161029

Summary: devel/ccache doesn't fully support clang yet
Product: Ports & Packages Reporter: c.kworr
Component: Individual Port(s)Assignee: Emanuel Haupt <ehaupt>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: Latest   
Hardware: Any

Description c.kworr 2011-09-26 07:20:08 UTC 
Most details are noted at https://bugzilla.samba.org/show_bug.cgi?id=8460. WIP.

The failing port is graphics/giblib but the damage to the packages might be severe - evrerything that depends on libtool can be corrupted.

Fix: 

Remove clang and clang++ from the compilers leaving a note that they could be readded later. This way the links to clang and clang++ would not be added by default and everything would work fine. Anyone can add clang and clang++ to EXTRA_COMPILERS to make use of ccache.
How-To-Repeat: Rebuild libtool with clang having ccache enabled. Try build any libtool based library and you will get:

clang: warning: argument unused during compilation: '-fpic'
building shared library xxxxxxx.so.x
ld: xxxxxx.So: relocation R_X86_64_32S can not be used when making a shared object; recompile with -fPIC
xxxxxx.So: could not read symbols: Bad value
clang: error: linker command failed with exit code 1 (use -v to see invocation)
