This is on 11.1-stable. > Make.conf is for building anything that uses make(1) and the build infrastructure in /usr/share/mk. Src.conf is for building the freebsd sources only. According to build(7), the freebsd sources include /usr/src, /usr/doc, and /usr/ports. So settings in both make.conf and src.conf affect ports builds. The difference appears when you use make to build your own software that isn't part of freebsd. For that, make.conf settings are applied, but not src.conf. At least, that's what the docs say. When I look at the .mk files in /usr/share/mk, it appears to me that src.conf gets used even for non-freebsd-source builds. When both files exist, variables set in src.conf will override same- named variables set in make.conf. Using VAR += value in both files will accumulate values into VAR rather than replacing them. -- Ian
