This sounds like one of your system headers is #define'ing `vector` as `__attribute__((something))`, but if that's the case then good luck compiling *any* C++ code :/

Can you confirm this by adding this next to that sts::vector line and seeing if it fires when you compile?

#ifdef vector
#error "`vector` is #define'd"
#endif

Looking at the rest of the build log, it looks like `bool` is also #define'd to something that can't be used as a type...

What OS are you running this on?

and what toolchain?

Fedora Rawhide. I'm mesa maintainer in Fedora and trying to switch from autotools to meson in our RPM package.

GCC, the standard one in Fedora ;)

Interestingly it works fine if I use autotools as a buildsystem.

Might it be related to this meson part:

if get_option('power8') != 'false'
  if host_machine.cpu_family() == 'ppc64le'
    if cc.get_id() == 'gcc' and cc.version().version_compare('< 4.8')
      error('Altivec is not supported with gcc version < 4.8.')
    endif
    if cc.compiles('''
        #include <altivec.h>
        int main() {
          vector unsigned char r;
          vector unsigned int v = vec_splat_u32 (1);
          r = __builtin_vec_vgbbd ((vector unsigned char) v);
          return 0;
        }''',
        args : '-mpower8-vector',
        name : 'POWER8 intrinsics')
      pre_args += ['-D_ARCH_PWR8', '-mpower8-vector']
    elif get_option('power8') == 'true'
      error('POWER8 intrinsic support required but not found.')

Oh, good to see you're doing the move! Don't hesitate to cc me and Dylan on any meson issue you have.

Good comparison point, I forgot to ask that.

So that really is the issue :/

Yes indeed, it sounds like a reasonable candidate for this issue.
You can try disabling it with `meson configure -D power8=false`.

I'll try to have a closer look tomorrow so see if `-mpower8-vector` is meant to work with C++ or not.

I see some code in autotools we don't have an equivalent of in meson, does adding `-Dcpp_std=gnu++11` fix this issue?

Created attachment 142723 [details] [review]
0001-build-correctly-check-for-ppc64le.patch

Some trivial fix for correctly detecting power8.

It seems that autotools was building clover with gnu++11 while the rest was built with c++11 which is not the case with meson.

Trying it out.

FYI, patch from earlier comment is not related to fix this bug, but is correcting altvec detection.

I have a similar patch in a series I'm about to send out (the debian guys ran into the same thing), but we actually need to do `host_machine.system().startswith('ppc64')` since we still support versions of meson that return `ppc64le` :/

There's another place where you need the same change.

you might be interested in:
 gitlab.freedesktop.org:dbaker/mesa.git fix-less-common-arches

Yeah, the gnu++11 fixes problem.

And also submitted https://gitlab.freedesktop.org/dbaker/mesa/issues/21.

I think this should be fixed now.
