Done in > <https://github.com/ccache/ccache/commit/c4284c78e9ff286ee5208f449af4c2aaba062d37>. In the interim I discovered a workaround that seems to work, for anyone who's also affected by this. Instead of setting CCACHE_PREFIX to distcc, I pointed CCACHE_PREFIX to this: #! /bin/sh unset MFLAGS ${!MAKE@} exec distcc "$@" This clears make variables from the environment and when the linker invokes make for ...whatever it needs to invoke it for, against a manufactured makefile it generates on the fly... it doesn't go look for the job server file descriptors, and go sideways. _______________________________________________ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
