Hi, I'm trying to compile GMP 5.0.5 with GCC 4.3.1 and am running into a weird issue that I haven't run into before when compiling it on IRIX.

Code:

../gmp-impl.h:189: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'gmp_uint_least32_t'

There's not an issue with the gmp-impl header obviously, but I'm not exactly sure where the problem actually lies. Any suggestions?

Line 189 of gmp-impl.h (as mentioned in the error message) tries to typedef gmp_uint_least32_t to the operating system's uint_least32_t type. On IRIX that's defined in stdint.h but only for C99 mode. So if you're compiling C++ there's no uint_least32_t available.

Also, gmp-impl.h will prefer to use inttypes.h instead of stdint.h (lines 110 to 116) if both are available. On IRIX, inttypes.h doesn't define uint_least32_t at all, regardless of mode.

My solution (when compiling gmp-4.3.2 a few years ago) was to just pass ac_cv_type_uint_least32_t=no to configure before building GMP to force it to fall back to other code (gmp-impl.h lines 191 to 200). Fortunately, GMP is well-written in that regard! That work-around should also suffice for the version you're trying.

Hm, thank you, I'll try that. What's weird is that I didn't have to do that before when compiling it on another machine though...
