It really does appear to be a simple matter of first making egcs "take over" the system compiler: # cd /usr/ports/lang/egcs # make all install PREFIX=/usr # ln -fs /usr/bin/eg++ /usr/bin/c++ # ln -fs /usr/bin/egcc /usr/bin/cc # cd /usr/src remove cc from /usr/src/gnu/usr.bin/Makefile SUBDIR list remove libstdc++ and libobjc from /usr/src/gnu/lib/Makefile SUBDIR list Then make the world and the kernel. I also haven't noticed that the executables are any smaller or larger either way, and I've captured a fair amount of "cc -v" output to ensure that egcs is, in fact, the compiler being used. :) - Jordan To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
