Trace mode fails when ccache is used

[ryandesign (Ryan Carsten Schmidt)]

I have configureccache yes in my macports.conf. If I try to build any port that honors that setting, the configure phase fails with:

ccache: command not found

[raimue (Rainer Müller)]

I use the same, but I cannot reproduce the problem. The ccache port is ​added automatically as a dependency for trace mdoe when it is enabled.

Which port did you try to build? Note configureccache is the name of the setting in macports.conf, but ports should use configure.ccache.

[ryandesign (Ryan Carsten Schmidt)]

Any port, such as zlib.

Aha: it works if I use the ccache port. I was using the ccache-devel port.

Proposed fix: ​https://github.com/macports/macports-base/pull/57

In 64c60f29d85d6290913efb6dd1c718e9f5da811e/macports-base:

Find port providing ccache binary for trace mode

Instead of assuming the ccache binary is provided by the ccache port,
query the registry which port provides ${prefix}/bin/ccache if it exists
and also include all dependencies.

Closes: #55680
