inkscape @1.3, inkscape-devel @1.3: error: use of undeclared identifier 'xmlFree'

[randymortensen (Randy Mortensen)]

During a regular "port selfupdate" and "port -u upgrade outdated", Inkscape failed to upgrade. Also tried clean then install with same failure. Inkscape-devel also fails.

Curiously Inkscape "port health" shows green for sonoma arm64 at ports.macports.org (although that may refer to version 1.3, not 1.3.5 which is the updated version). main.log file attached

libxml2 was just updated from 2.11.x to 2.12.x; inkscape 1.3 is incompatible with this new version.

Here is the one-line change that we need to add to the port to fix it:

​https://gitlab.com/inkscape/inkscape/-/commit/694d8ae43d06efff21adebf377ce614d660b24cd

[ryandesign (Ryan Carsten Schmidt)]

And just to clarify, the inkscape port is at version 1.3 revision 5 and the inkscape-devel port is at version 1.3 revision 2. There is no version 1.3.5 yet. There is a version 1.3.2 to which we could update the ports but it does not contain the fix for this issue.

Replying to randymortensen:

Curiously Inkscape "port health" shows green for sonoma arm64 at ports.macports.org (although that may refer to version 1.3, not 1.3.5 which is the updated version).

It refers to the last time builds took place, which was for version 1.3 revision 5 on February 14. Subsequently, on February 27, libxml2 was updated to 2.12.x, so if a build of inkscape were attempted now, it would fail.

In 3b09622203ec5778d4211c1853e3b1e24a5732bd/macports-ports (master):

inkscape*: Fix build with libxml2 2.12.0, poppler 24.03.0

Closes: #69422
