On the Sgi I have USE_BIG_ENDIAN defined.

Hi, Do you have NON_WINDOWS defined? Assuming that, could you detail the compiler & settings you are using? I'm specially interested on alignment & optimization degree. I'm unable to check directly USE_BIG_ENDIAN, but seemed to work on other users.

USE_C 1 USE_TRILINEAR 1 NON_WINDOWS 1 USE_INT64 1 #pragma pack() is not valid on the sgi. What sort of alignment were you after? pack(0)? Actually after more testing last night. -O0 works -O1 works -O2 does not work -O3 does not work -O1 and -O2 should do the same thing with math optimizations. I'll keep digging.

Hi, >#pragma pack() is not valid on the sgi. What sort of alignment were you >after? pack(0)? Yep, that is! The idea is, lcms.h does need byte-alignment. This don't mean your whole application does need to be byte-aligned, only lcms.h. On end of lcms.h pack() is supposed to restore original alignment.Then, each compiler implements this sort of thing differently. Some does use pack(0), some pack() and others are using arcane #pragma. If you can obtain somehow byte alignment on lcms.h, all will work fine ... hopefully! :) Regards, Martí. |
