Trying to combine ccache and colorgcc. Following link text:
- my g++ is soft link to colorgcc
- ~/.colorgccrc contains line: "g++: ccache /usr/bin/g++"
When running g++ --version receive:
Can't exec "ccache /usr/bin/gcc": No such file or directory at /usr/lib/perl5/5.8.8/IPC/Open3.pm line 246.
open3: exec of ccache /usr/bin/gcc --version failed at /usr/local/bin/colorgcc/gcc line 208
Any ideas how to solve it?
Answer
Just came across this same issue. For me, the problem could be solved by carefully setting environment variables:
# Make "g++" command call colorgcc
export PATH="/usr/lib/colorgcc/bin:$PATH"
# Tell ccache to invoke compilers in /usr/bin
export CCACHE_PATH="/usr/bin"
Then all I had to do was edit colorgcc's config file (/etc/colorgcc/colorgcc or ~/.colorgcc) and tell it to call ccache instead:
g++: /usr/lib/ccache/bin/g++
gcc: /usr/lib/ccache/bin/gcc
c++: /usr/lib/ccache/bin/g++
cc: /usr/lib/ccache/bin/gcc
g77: /usr/lib/ccache/bin/g77
f77: /usr/lib/ccache/bin/g77
gcj: /usr/lib/ccache/bin/gcj
This of course only works if you have colorgcc's symlinks installed in /usr/lib/colorgcc/bin and ccache's symlinks in /usr/lib/ccache/bin - adjust accordingly.
