Your Solaris is a little broken. getrusage was in Solaris preceding
version 2.4, and after version 2.4, but not in version 2.4. Odd. So
one solution is to upgrade to Solaris 2.5. Another is to dynamically
link a shared object containing getrusage before running the
executable. This is easier than it sounds. See
http://www.cse.ogi.edu/~simonpj/ghc-bugs.html#getrusage for more
details. (The above recipe creates a dummy getrusage which does
nothing. You can go one step further and create a real getrusage.so
by extracting it from the library with the following magical
incantations:
ar x /usr/ucblib/libucb.a getrusage.o
ld -G -o getrusage.so getrusage.o -lc
)
