After installation of MorphOS SDK 3.2 when I try compile using NoAltivec option:
g++ -O0 -noixemul -traditional-cpp -mcpu=powerpc -mno-altivec -c -o o/gcc-morphos-stable/main.o main.cpp
I get:
cc1plus: Invalid option `no-altivec'

Previous version of MOS SDK has no problem with no-altivec.


Could someone tell me if I used -mcpu=740 (-mcpu=G3 doesn't work too), the binary would work on machines without AltiVec?

Are you shure that the compiler generates Altivec instructions with -mcpu=powerpc?
I don'tthink so.

Problem has already been solved. After update SDK my default compiler was set to GCC 2.95.x. I forgot set 4.4.5 again. :)

But you don't need -mno-altivec because it is default.
