I am trying to use ccache with pkgsrc. I read the guide and have PKGSRC_COMPILER= ccache gcc in /etc/mk.conf. Packages now depend on ccache, and the wrapper scripts seem to use ccache, but my cache statistics remain 0 after building editors/emacs22 gdt 136 /usr/pkgsrc/editors/emacs22 > ccache -s cache directory /home/gdt/.ccache cache hit 0 cache miss 0 files in cache 0 cache size 0 Kbytes max cache size 5.0 Gbytes Is there some other cache location for pkgsrc? I found '.ccache-cache' in work, but surely the point is that when you build a package again the cache will be used. gdt 165 /usr/pkgsrc/editors/emacs22/work > CCACHE_DIR=.ccache-cache ccache -s cache directory .ccache-cache cache hit 0 cache miss 154 called for link 17 compile failed 10 preprocessor error 13 autoconf compile/link 124 no input file 3 files in cache 308 cache size 5.9 Mbytes max cache size 1024.0 Mbytes But 'make clean' in editors/emacs22 blew that away. I see reading mk/compiler/ccache.mk that this is documented. But it seems like a very strange default. What is the recommended setting for CCACHE_DIR? How does one manage a shared cache for builds as me vs root? Or is the thinking that reading a root ache as me is a disclosure vulnerability and writing a root cache an integrity vulnerability?
