dvisvgm-3.6 does not build on PPC Leopard, Mac OS X 10.5.8, because of configure not finding kpathsea/kpathsea.h

[ballapete (Peter "Pete" Dyballa)]

It exists,

-rw-r--r-- 1 root admin  766 23. Apr 2025  /opt/local/include/kpathsea/kpathsea.h

possibly from last years (now defective, because dylibs changed and it can't be re-built anymore) TeX Live installation, port only tells:

leopard pete 220 /\  port provides /opt/local/include/kpathsea/kpathsea.h
/opt/local/include/kpathsea/kpathsea.h is provided by: texlive-bin
leopard pete 221 /\  port installed -v texlive-bin
The following ports are currently installed:
  texlive-bin @2025.74524_1+x11 (active) requested_variants='' platform='darwin 9' archs='ppc' date='2025-04-23T13:00:29+0200'

The error shows up like this:

I think this is the actual failure:

 561 configure:19840: checking for kpathsea/kpathsea.h
 562 configure:19840: /opt/local/bin/gcc-mp-15 -c -pipe -I/opt/local/libexec/openssl3/include -Os -arch ppc -I/opt/local/libexec/openssl3/include -isystem/opt/local/include conftest.c >&5

That's the same that prevents texlive-bin 2025 from rev-upgrade-ing.

Martin Gieseking has answered that he only maintains the pure code. Its integration into TeX Live and MacPorts needs support from others.

[ballapete (Peter "Pete" Dyballa)]

TL '25 could be built from source, so changes for TL '26 introduced the bug.

Complaint to TUG tlbuild mailing list has arrived: ​https://tug.org/pipermail/tlbuild/2026q2/006000.html.

Martin Gieseking sent me this:

This seems to be the same issue as reported here: ​https://tug.org/pipermail/tex-k/2026-January/004247.html and is probably related to changes introduced with C23.

[ballapete (Peter "Pete" Dyballa)]

With the correct C header file kpathsea/getopt.h the software built – but many tests fail: #74048.
