This is on G5 with GCC 12.3.0.

@pkubaj Maybe you could give an advice here?

[pkubaj]

I think it may be because altivec.h is not included, but I can't really test, my POWER hardware is POWER9.

(Requesting @vlazzarini to evaluate this issue.)

[vlazzarini]

It's hard for me to help as I don't have a PPC to test. Maybe best to disable vector code with -DPFFFT_SIMD_DISABLE if this can't be built.

[barracuda156]

@pkubaj @vlazzarini Okay, at least some functions should be available, like vec_lde is there already in old Apple gcc: https://opensource.apple.com/source/gcc/gcc-5479/gcc/testsuite/gcc.dg/vmx/3c-01.c.auto.html

Let me see what can be done about this.

P. S. Disabling is a trivial fix, but of course we rather have it working.

[barracuda156]

@pkubaj Looks like you were absolutely right. Adding #include <altivec.h> solves the problem. (Now I wonder why it was not there to begin with, it should not be Apple-specific thing.)
