I have a source directory which uses makefile to compile the code. This makefile/configure file is not written for ccache compatibility. So I thought to use ccache. I created alias in .bashrc as alias gcc='ccache gcc', but Makefile is still not considering this definition of gcc. So is there anything I can do without touching Makefile/configure file such that it takes ccache gcc instead of gcc.
Also CC='ccache gcc' ./configure is not an option, since it does not ask for CC.
If I write Makefile then I can provide ${gcc), but this is not an option, since I am not writing Makefile. Is there any way by which we don't need to change anything in source file, but still enable ccache compiling.
As described by the fine manual: Create a symlink named "gcc" in a directory that is listed in your PATH before the one containing the real gcc. This will cause ccache to be used transparently, with no need for any change to the makefile.
