Package: ccache
Version: 2.3-1.1
Severity: important
I use ccache by symlinking /usr/local/bin/gcc to /usr/bin/ccache.
However when I use the scons build environment this completely breaks
any use of gcc.
The reason is that scons (to "ensure" a consistent build environment)
clears all environment variables. This includes $HOME, which ccache (at
least in my configuration) needs to find the cache dir. So I get errors
like
ccache: failed to create (null)/.ccache (No such file or directory)
any time I run scons.
I've already reported this as a bug to the scons people. They claim
it's a feature of scons, not a bug (and offered a complex workaround by
changing my scons configuration...but I don't use scons enough to make
this worthwhile).
I'd suggest that if getenv("HOME") is NULL (or in general, if the cache
dir can't be found) that ccache should just run gcc rather than exiting
with an error. It may be useful to have a warning message but an error
is avoidable.
