make error package: libgd-2.3.2

[Yan Bo Ti]

Hello all, firstly, thank you for your hard work.

I am trying to compile sage from source, because I can't seem to do sage -pip install if I were to install it using pacman.

But in the course of building sage, I encountered an error with libgd. Is it possible to continue without installing libgd? I've included the log file in this post. Thanks once again.

this is caused by a bug in libgd, which detects external libraries it
can use incorrectly in this case. Your log says

** Configuration summary for libgd 2.3.2:

Support for gd/gd2 images: yes
Support for Zlib: yes
Support for PNG library: yes
Support for JPEG library: no
Support for WebP library: yes
Support for HEIF library: yes
Support for AVIF library: no
Support for TIFF library: yes
Support for Freetype 2.x library: yes
Support for Fontconfig library: no
Support for Xpm library: no
Support for liq library: no
Support for complex text: no
Support for pthreads: yes

Of these, only PNG is needed. We'll be fixing this in
https://github.com/sagemath/sage/pull/35477
Meanwhile you may manually apply the fix from there:

Replace your build/pkgs/libgd/spkg-install.in with
https://raw.githubusercontent.com/sagemath/sage/212afefe219cbfa3b4f64c26ced60f63699b64b3/build/pkgs/libgd/spkg-install.in

and run ./configure && make

This works now. Thank you so much, Dima!
