I have made some changes to the code now, please let me now if there are any errors @twaik

Squash the changes please.

Change commit description to addpkg(main/mujs): 1.3.4 and force-push please.

Seems like it did not pick termux's CFLAGS and LDFLAGS.

@harryfrzz what twaik said is correct, but to explain further, if it fails in CI here but worked in your on-device build, it means that it needs to be edited further to be compatible with "cross-compilation" which is when software is built for Termux using the termux-package-builder Docker container without Termux being present. If you don't understand about that and need some help with it then let me know.

DO NOT use merge commits please. PRs containing merge commits are not being merged.

Sorry,will not do it again

Squash please.

I have added a patch file to fix the ldflags error.I have also tried to compile it and it successfully compiled for aarch64.
Please take a look at the changes made

Seems like building was fine. Now someone should test deb files of https://github.com/termux/termux-packages/actions/runs/18465870776?pr=26862 .

I have made another one by editing this until there were fewer unnecessary steps,

in case you would like it to be shorter you can use my version:

I have tested my version on-device it looks like this

~ $ mujs
Welcome to MuJS 1.3.5.

@Grimler91 Please take a look at the new package that has been implemented

I meant to get back to this last week but didn't have the time to.
This should be good to merge, there's no reason to keep it sitting here collecting dust.

I'll merge this tomorrow if there is no further comments.

This PR is fine, but I might open a PR afterward to further revise it with my own changes which shorten the build.sh.

And then I forgot to get to it again.
Merging now.
