I want to use SSE instructions via xmmintrin.h, but both visal c++ and mingw32 (devc++) fails to compile this header (the one included in devc++). They return several errors (missing ; undeclared indentifier, etc). Where can i get a proper intrinsics header? Please somebody help! Thanx in advance...

A quick search on Google makes me think that the file originally is from Intel.
It was a bit involved, but most of the hits where from around early May so it may well have been fixed in some update.. You can probably get that from your local gcc supplier.

stupid question, but you are using a compiler that supprts intrinsics?

(Intel''s compiler and VC7.1 - not sure about VC 7.0 or VC 6.0 + processor pack, they *might* do)

it was bundled with the compiler, so i guess it supports. in the case of vc++ i dont know... btw vc++ inline assmebler was said to recognize sse instructions, but they did not work too.
i will take a look at intel''s an microsoft''s...

thank you
