mesa: Unsupported platform, No pipe_atomic implementation selected

[ryandesign@…]

I'm afraid that with mesa 7.10.3_0 we are back to getting this error again on Tiger ppc (seen previously in #24393):

The last version of mesa successfully installed on this system was 7.8.2_2.

Yeah, that was why gallium was disabled in 7.8.2 (I re-enabled it hoping someone had added ppc support in the interim).

mesa is openmaintainer ... would you mind taking this on? Just re-disable gallium (uncomment it). Also test osmesa.

[ryandesign@…]

Has duplicate #29959. Sorry I haven't yet gotten around to trying to resolve this on my G4.

[jeremyhu@…]

Can you try with r80341? That removes galium from the targets, so give that a go. If it still fails, post a new log, so I can see the new failure point...

r88037 (see duplicate #32552) was another attempt to fix this but it does not change the error message for me.

Replying to ryandesign@…:

I took some time to investigate further. If GALLIUM is the problem on PPC then Mesa-7.11/src/mesa/Makefile might need a patch. Its line #6 has

MESA_LIBS := libmesa.a libmesagallium.a

By commenting libmesagallium.a the build process should proceed. I tried it kind of manually. It led from the state with the failure to another error with not finding X11 libraries. I'm trying this with a new patch file (Gallium-PPC.patch), and port will need some hours, either to succeed or to fail again, so here is the patch:

The patch seems to work:

DEBUG: clean phase started at Sun Dec 18 01:46:41 CET 2011
--->  Cleaning mesa

(And the build process was pretty fast!) The results are here, taken from the deactivating and activating steps:

Deactivating mesa @7.6_1+darwin_8+hw_render     Activating mesa @7.11_2+python27

Looks complete, except for the two binaries.

mesa @8.0.1_0+python27 (active) could be built on PPC Tiger 10.4.11. A few times these commands failed:

make[5]: xcrun: Command not found

mv: rename libOSMesa.8.dylib to ../../../../lib/libOSMesa.8.dylib: No such file or directory
