Version:            (using Devel)

I'm using ccache to build KDE and have an issue with kdepimlibs.

Previously, ccache was in /usr/local/bin and a few symlinks were created for
g++ and gcc. and everything was fine.

Today, I removed these files and changed my .bashrc :

export CC="ccache gcc"
export CXX="ccache g++"

and now, kdepimlibs fails:

cmake /home/krop/kde/src/KDE/kdepimlibs -DCMAKE_BUILD_TYPE=Debug
-DCMAKE_INSTALL_PREFIX=/opt/kde4/kdepimlibs -DKDE4_BUILD_TESTS=on

  ccache, a compiler cache.  Version 2

  Usage:

 ccache [options]
 ccache compiler [compile options]
 compiler [compile options] (via symbolic link)

etc...


removing ccache from the above exports solves this issue.
