2 important facts: - A test C program, using one of the "undefined" functions (isnan) compiles with GCC and runs - I went in by hand and temporarily replaced each version of math.h on my computer with a version that has the necessary functions defined.

This makes it seem like cabal doesn't have access to _any_ math.h file, but if this were the case, wouldn't I get many more undefined-function errors than I do?

Unless you are using an older ghc with -fvia-C, is not used or useful. The modern -fasm codegen doesn't know what to do with C-level declarations. If your is using macros to define gamma as something else, you will need to find that something else or use a wrapper library. I note that OS X doesn't have a gamma(). There are lgamma() and tgamma() and variations thereon. (and no related macros in , confirming that it is not related.) -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
