As I understand it, The SGI compiler refuses to define any of the <stdint.h> symbols unless compiler 'c99' is used to tell the compiler it is to be in C99 mode. The current stdint_.h file mechanism does not come into play because config.h believes the file exists. It does exist, it is just not useful. > If not, then the current solution is OK, albeit annoying. If so, then > what breaks? We can test for that. Apparently, none of the intNN_t or uintNN_t or intmax_t or uintmax_t types are defined. For our own code, we could just add a #if HAVE_INTTYPES_H #include <inttypes.h> #endif but that does not really help us with all of the GNULIB code that includes <stdint.h> and fails to get the types expected. In the best of all possible worlds, the SGI system will figure out that the system <stdint.h> should not be used and let the stdint_.h GNULIB file be turned into an <stdint.h> that will #include <inttypes.h> as needed. > Perhaps the simplest way to see what might break would be to inspect > the SGI stdint.h and see what goes wrong in c89 mode. Doing a '#include <inttypes.h>' would appear to work around the difficulty for SGI boxes... http://www.nersc.gov/nusers/resources/software/libs/io/hdf5/release-notes-1.6.4.txt has this to say: * Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but it has a "guard" statement in stdint.h that will #error and skip the rest of the header file if C99 option is not used explicitly. Hardset $CC to c99 will resolve the problem.
