What steps will reproduce the bug?

termux-install-biber

What is the expected behavior?

biber has been installed properly.

cpan does not seem to respect *FLAGS. Then we have to patch the source of XML::LibXML. Fortunately termux-install-biber already patches some other modules and so hopefully that can be possible. @Grimler91 What do you think?

FYI, personally as a quick hack on the user side I would use a CC wrapper:

#!/bin/sh
exec clang -Wno-error=incompatible-function-pointer-types "$@"

By the way, I compiled XML::LibXML by changing the warning level in makefile to -Wno-everything. Then termux-install-biber works as expected.

HOWEVER

It installs biber 2.18, which is incompatible with the latest biblatex!

ERROR - Error: Found biblatex control file version 3.10, expected version 3.9. This means that your biber (2.18) and biblatex (3.19) versions are incompatible. See compat matrix in biblatex or biber PDF documentation. INFO - ERRORS: 1

Need to be fixed ASAP! @Grimler91

P.S. TeXLive is installed with the latest texlive-installer, which was just updated several days ago. See #16494

[Grimler91]

I am thinking biber should be moved to termux-user-repository in any case since it is just an installation script. I started looking at that some time ago, will have a look at that again and add another patch for this issue while I am at it.

Thanks for reporting the issue!

I build biber 2.19 from source, it works fine. (biber 2.20 won't work......)

[Grimler91]

So, updated biber installer package has been added to the termux-user-repository. To install new version, do:

pkg install tur-repo
pkg install biber-installer
termux-install-biber
