I was working on Debian, modifying GPicView.
I have to edit and compile the source several times.
I know that it is a time costly process and I know that gcc, make, and some other tools create cache files, but throw them away after the binary is build.
So I looked for a way to keep the cached files, to speed up the building process. And that’s where I found ccache.
From the site:
ccache is a compiler cache. It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again.
Under Debian you install ccache with:
sudo apt-get install ccache
But how do I use ccache for all compilations? The question is answered here.
I decided for a variation of the “symlinks” method:
for tool in /usr/lib/ccache/* do sudo ln -s /usr/bin/ccache /usr/local/bin/$(basename $tool) done
And after installing I run “which gcc” to make sure that the correct link is being used.
How do I check if ccache is working properly? Compile something and then run:
