I noticed that my installed version of gcc is linked to ccache. When I type gcc on the command line, I get "gcc: no input files". When I type ccache, I get the ccache usage message. But when I type "ccache gcc" I get "gcc: no input files". It seems that gcc is engaging ccache with the option "gcc" appended somehow. I would like to know how the link name, gcc, engages ccache with the gcc option specified.
It doesn't. ccache can tell what command name was executed when it starts, and it knows that if it was called 'gcc', it should run gcc. The same is true if you run g++ linked to ccache... it will run g++.
