libpixman @0.42.2: error: expected identifier before ‘__attribute__’

[ilovecrts]

I am trying to install matplotlib with "sudo port install py312-matplotlib" and libpixman is a dependency. Installation / building of libpixman fails.

My terminal output when I run "sudo port install libpixman" is:

I open the log file as instructed and I see an error logged at the end of the file.

A copy of my entire log file should be attached here.

Can anyone help me here?

I am a bit of a novice here, so please forgive me if I am unable to provide more details or if my understanding seems low. :)

I am open to running tests and experiments if needed.

Thank you very much!

I fixed that here

#69385

with a trivial patch you can try if you like

[ryandesign (Ryan Carsten Schmidt)]

Which was a duplicate of #68473.

Ken, if you have a fix, please submit a pull request.

It worked! :)

Thanks, Ken!
