I tried the maximum: port -vd build -sk cairo +opengl +x11 +quartz – with old mesa version 17.1. (I could also see that configure failed to detect poppler and libspectre which I have not yet checked in detail, some other house work is waiting.)

Main.log from PPC Tiger

[kencu (Ken)]

This new patch Ryan added doesn't build on some older systems.

I just commented it out while it gets sorted out.

[ryandesign (Ryan Carsten Schmidt)]

This new patch Ryan added doesn't build on some older systems.

I wasn't aware that the recently-added patch caused problems on older systems; this ticket is the first I've heard of the problem. The patch comes directly from the developers of cairo and was added to fix a crash on Big Sur; see #61586. If the port doesn't build with this patch on some systems, please report the problem to the developers so that they can fix it. Once they do, we can update the patch with their fix.

(I could also see that configure failed to detect poppler and libspectre which I have not yet checked in detail, some other house work is waiting.)

That's intentional. The cairo port deliberately patches the configure script to ensure that poppler, libspectre, and librsvg are not used, even if they are installed, because that would result in a circular dependency, which is not allowed in MacPorts.

[ballapete (Peter "Pete" Dyballa)]

This patch is obviously the cause for the build failure here on Tiger: changing patch-cairo-quartz-surfaces.diff into a comment let cairo @1.16.0 build – with GCC 7.5. I am going to run make check and then I'll try to build it also with GCC 4.2.

Reporting is a bit complicated! TenFourFox runs into a very high load when I am in the Cairo bug reporting page. Actually it's some product on Big Sur that has a problem! But you're right: the patch should be incorporated for Big Sur only.

I didn't say that; in fact I ​said the opposite. But certainly it's up to the developers how they would like to fix this.

Replying to ballapete: make check ran for a few hours, produced 30 core files à 144 MB and said: All well! The build with GCC 4.2 also succeeded in absence of the Big Sur patch. I am running make check now.

[ballapete (Peter "Pete" Dyballa)]

On macOS High Sierra, Version 10.13.6, cairo @1.16.0_1 built from sources with clang version 9.0.1 and the Big Sur patch patch-cairo-quartz-surfaces.diff. And it also built without that patch!

[ballapete (Peter "Pete" Dyballa)]

make check succeeded better with GCC 4.2: no core file and

97 Passed, 447 Failed [241 crashed, 10 expected], 26 Skipped

vs.

64 Passed, 479 Failed [332 crashed, 10 expected], 26 Skipped

I am going to report in cairo bugs.

This is the failure on PPC Leopard, Mac OS X 10.5.8 with the Big Sur patch:

I just created ​https://github.com/macports/macports-ports/pull/9897 to address this issue. I forgot to note this ticket in the commit log, but I did catch it in the PR log. The fix for the incompatible types in return is very clear once you parse the code. I add in a fix that's upstream already for good measure.

[michaelld (Michael Dickens)]

In e9fce065c100a6fc78a0c98c151cc9819749f1c1/macports-ports (master):

cairo[-devel]: add fixes to allow building on older MacOS

All changes are already merged upstream as noted in the patch comments; these are backports.
