There were a bunch of undefined symbols that I didn't track down. Hopefully there's just a missing header file. I need to dig into it more. I just disabled it because I was hoping that would be the only issue. It wasn't but, I had stop working before I could try again with stack traces enabled. > > The f77_get_fortran_handle_max.m4 change is because FreeBSD's eval > > appears to use ints internally so they overflow to negative numbers and > > cause problems.

(ditto for ompi_cint_max) On FreeBSD, eval is using 32-bit signed numbers internally on i386 (it looks like it uses longs in general, but I haven't tested on a 64-bit machine yet). This means that when you compute 2^31 you get INT_MAX + 1 which is negative. Subtracting one gives INT_MAX so you get the right value despite the sign weirdness. Assuming I'm correct about longs being used, we'll also be OK on 64-bit machines even if this code is used to compute the maximum value of a 64-bit signed integer. It won't work for unsigned numbers on either system though. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE. PGP fingerprint 655D 519C 26A7 82E7 2529 9BF0 5D8E 8BE9 F238 1AD4
