[GRASS5] [compiling on two or more processors?]

GRASS GRASS developer

I'm trying to compile Grass5 on machine with two processors:

+ /usr/bin/make -j2
test -d /home/users/ser/rpm/BUILD/grass5.0.0pre4/dist.i686-pld-linux-gnu
|| mkdir -p -m 755

|| mkdir -p -m 755
/home/users/ser/rpm/BUILD/grass5.0.0pre4/bin.i686-pld-linux-gnu
test -d src/CMD/next_step || mkdir -p -m 755 src/CMD/next_step

Why does it fail?

Why does it fail?

The usual reason why parallel make fails is that one target depends
upon another but doesn't actually specify it as a dependency.

In this case, it looks like something is being built (from the
"do-compile" target) before src/CMD/head/head has been renamed to
src/CMD/head/head.<arch> (in the "pre-compile" target").

Try running "make pre-compile" first, without any "-j" switch, then
run the parallel make once that has completed.

If that doesn't work, it's unlikely to be fixed in 5.0.x. The build
system is intended to be replaced for 5.1.
