g++, colorgcc and ccache

Question

Trying to combine ccache and colorgcc. Following link text:

• my g++ is soft link to colorgcc
• ~/.colorgccrc contains line: \"g++: ccache /usr/bin/g++\"

Answer 1

Here is how to patch colorgcc. The problem is with

exec $compiler, @ARGV

and

$compiler_pid = open3('<&STDIN', \*GCCOUT, '', $compiler, @ARGV);

$compiler is in your case "ccache /usr/bin/g++". We need to change it so that $compiler is ccache and /usr/bin/g++ is prepended to @ARGV

After the line

$progName = $1 || $0;

do following modifications:

$shell_command = $compilerPaths{$progName} || $compilerPaths{"gcc"};
@shell_array = split(' ',$shell_command);
$compiler = shift @shell_array;
if ( scalar (@shell_array) > 0 ) {
  unshift (@ARGV, @shell_array);
}

replacing the line

$compiler = $compilerPaths{$progName} || $compilerPaths{"gcc"};
