ccache port doesn't set itself up as gcc-4.2

[bzbarsky (Boris Zbarsky)]

The portfile for ccache has the following:

    foreach {bin} {
	    cc
	    gcc gcc2    gcc3    gcc-3.3 gcc-4.0
	    c++ c++3    c++-3.3 c++-4.0
	    g++ g++2    g++3    g++-3.3 g++-4.0
    } {
        ln -sf ${prefix}/bin/ccache ${destroot}${symlinks_dir}/${bin}
    }

At least on Leopard, it should also set up gcc-4.2 and g++-4.2.

r64755, those symlinks are too much of a bother to maintain.

So wait. Doesn't this make ccache not work correctly out of the box? Shouldn't there be at least some indication when one tries to run "ccache" or something that it needs more setup?

[landonf (Landon Fuller)]

This forces all ccache users to individually set up symlinks rather than work out of the box. New compiler versions are not released very often. I'd really like to re-integrate the symlink code, which was in place for 8 years (2002 through 2010) and relied on by users (including myself).

Replying to nox@…:

I agree with the other posters. Removing the symlinks from the setup code makes no sense.

I just "upgrade" ccache, and suddenly it stops working with no explanation? WTF. There should be at the minimum documentation to explain how to set up ccache correctly.

Maintainership relinquished in r69969.

Symlinks restored and a gcc-4.2 symlink was added in r71514
