mesa @12.0.1_1 fails to build on Leopard i386

compile fails with this error

../../include/GL/glx.h:165: error: previous declaration of 'GLXContext' was here
make[4]: *** [glxcmds.lo] Error 1

include/GL/mesa_glinterop.h has a block where it appears that glx.h is not expected to be included

/* Forward declarations to avoid inclusion of GL/glx.h */
 typedef struct _XDisplay Display;
 typedef struct __GLXcontextRec *GLXContext;

However it will be included if Apple GL headers are used so, I patched it there to stop the double reference it seemed logical to test for definition of

#ifndef APPLE_GLX_CONTEXT_H

Then it built and installed for me

[jeremyhu (Jeremy Huddleston Sequoia)]

Thanks. I've got a bit of a queue on my lap. It looks good to me, so if someone can commit, I'd appreciate it.

[jeremyhu (Jeremy Huddleston Sequoia)]

Or send a pull request, and I'll merge it.

same error on 10.7 x86_64

FWIW, same error on 10.5.8 PPC

[ken-cunningham-webuse]

I'm not sure over what range of systems this patch needs to be applied. I know it was not needed on 10.12, and it appears to be needed on 10.7 and lower.

10.8 to 10.11 are unclear to me as yet.

I made a PR for 10.7 and lower, but I think the full extent of where it is needed needs to be explored a bit further.

[dbevans (David B. Evans)]

Per ​https://packages.macports.org, binary packages where successfully built by the buildbots for darwin 10 through 16 or 10.6+. Both 32 bit and 64 bit builds were successful on 10.6. So looks like the problem is 10.5 and earlier.

[ken-cunningham-webuse]

and yet I had the problem on 10.7 as above ... I won't pretend to have this one figured out. Rebuilding it on 10.7 now just to see if it still fails on me.

Perhaps this patch can be applied unconditionally, and only will be used if needed?

I set the PR to allow mods from maintainers, if anyone gets deep insight.

Replying to udbraumann:

FWIW, same error on 10.5.8 PPC

Patch also works on 10.5.8 PPC, thanks!

[ken-cunningham-webuse]

Yep. Build on 10.7 failed again. I have my 10.7 system set up with libcxx enabled. Perhaps that is influencing the build? Build failure log for 10.7 attached...

[ken-cunningham-webuse]

I wonder if this error

error: redefinition of typedef 'Display' is invalid in C [-Wtypedef-redefinition]

might be due in part to redefining typedefs only being valid under certain situations. The build that fails on 10.7 is using this standard in the build line...

-std=c99

[ryandesign (Ryan Carsten Schmidt)]

That's a syntax error. You need curly braces instead of parentheses.

[ken-cunningham-webuse]

crud. Sorry - will fix.

… and it built!

Mac OS X 10.6.8, Snow Leopard, x86_64.

[ken-cunningham-webuse]

I just tried this patch on Sierra, and mesa builds and destroots without error with the patch applied.

So I suspect this patch might just be applied unconditionally to all systems, therefore -- but I don't fully understand the implications of doing so, if any.

[arboz]

Replying to ken-cunningham-webuse:

I wonder if this error

error: redefinition of typedef 'Display' is invalid in C [-Wtypedef-redefinition]

might be due in part to redefining typedefs only being valid under certain situations. The build that fails on 10.7 is using this standard in the build line...

-std=c99

As I noted earlier it seem to be related to including the APPLE GL headers

it seems ths would not be true if using some other platform (linux or BSD), however since this is macports it seems correct to include the patch.

Since I am an oldguy I barely know whether compiling with

-std=c++11

and without the

[-Wtypedef-redefinition]

would work.

The most recent revision built just fine for me on Leopard i386

#52958 seems to be about this same issue
