emacs does not build with libxml support even though it's specified as a dependency and detected at compile time

[nealsid]

Hello,

Just wondering if it's possible to have libxml available on the package build machines. This way, when Emacs is built, it will be built with libxml support, and packages like eww will work out of the box. Emacs' build process only needs to find the library at build time for xml support to be built, no configuration options need to be set. The FMRI for libxml is pkg:/library/libxml2.

Thanks - if I can do anything here to help out or make this happen, let me know and I am happy to do so.

Emacs is currently built with the libxml support:

oi-userland/components/editor/emacs/Makefile

Line 257 in 3aebeb0

REQUIRED_PACKAGES += library/libxml2

Now that's strange! Sorry for not checking that in advance, I didn't realize required packages could be configured inside the Makefile. Seems to be a misconfiguration then, because on Emacs 30.2, inside Emacs, if I do M-: (libxml-available-p), it returns nil. I have double checked to make sure that libxml2 is installed on my system. Thanks for your help.

Is there any way I can see the log for a package build? What I tried doing is configuring Emacs from source on my OI system, and it found libxml2 correctly. I'd like to see what's different about when the package was built for the Hipster repository.

Build logs can be found here: https://hipster.openindiana.org
But, unfortunately, in this case the log is no longer available because old logs got removed about a week ago and emacs was built more than two months ago.

I'll keep an eye out after the next Emacs package build.

I was able to see some logs here https://hipster.openindiana.org/jenkins/job/oi-userland/13694/ but not the output of 'configure', unfortunately. I guess those were the logs that got cleared. Thanks again for your help.

Quick update: I can reproduce this on my local machine by building the package in oi-userland. In this case, libxml2 is detected but for some reason the preprocessor define is not set correctly during the build. If I build emacs from source on my machine, libxml2 is detected and available at run time. None of the patches seem relevant. I'll keep llooking into this.

The problem is limited to the nox variant of Emacs, and is because the nox variant of Emacs is built with a flag turning off all optional features, according to this line.

I think --without-all is not necessary for the nox variant of Emacs, because nox is meant to not have any dependency on X11/GTK libraries, but not necessarily meant to not have optional features, such as libxml.
