@m040601, @alerque,

Did you try to disable LTO option in makepkg.conf, or in PKGBUILD?

This type of linking error is very common with old projects when trying to build them with link-time-optimization enabled.

Like the previous commentator it also fails to build for me,

==> Starting build()...

collect2: error: ld returned 1 exit status
make: *** [Makefile:10: pdftxt] Error 1
==> ERROR: A failure occurred in build().
    Aborting...
     -> error making: pdftxt

Possibly something wrong in the PKGBUILD,

prepare() {
  cd "$srcdir/$pkgname-$pkgver"
  sed -i 's/-lopenjpeg/-lopenjp2/' Makefile
  sed -i 's/-lmupdfthird/-lmupdf-third/' Makefile
}

or here

build() {
  cd "$srcdir/$pkgname-$pkgver"
  make LDFLAGS="-lopenjp2 -lharfbuzz -lfreetype -lz -ljpeg -ljbig2dec"
}

This PKGBUILD has not been touched since 2020. The maintainer of this PKGBUILD has not responded to any comments.

Notice also that this tool might have been abandoned by its original author. Needs further checking.

It is still listed in the authors homepage, http://litcave.rudi.ir/ under "Others" and the "tar.gz" is still available.

But it is removed and not present in the authors' git repos

Either, https://github.com/aligrudi/ or its original mirror, https://repo.or.cz/projlist.cgi?name=e4985eabe11cacf799a880921d7ab569

I ran into trouble trying to build this recently (in a clean chroot), it might need some more patching or dependencies or something.

Fixed (thank you ChrisMorgan).

Failing to build again. Here’s a formatted patch that fixes it (paste it into foo.patch and run git am foo.patch to take the commit verbatim):

Subject: [PATCH] Patch Makefile to link against current mupdf

My attempt to build this package failed:

    ==> Starting build()...
    cc -c -Wall -O2 -I./include pdftxt.c
    cc -o pdftxt pdftxt.o -lopenjp2 -lharfbuzz -lfreetype -lz -ljpeg -ljbig2dec -lmupdf -lmupdfthird -lm
    /usr/sbin/ld: cannot find -lmupdfthird
    collect2: error: ld returned 1 exit status
    make: *** [Makefile:10: pdftxt] Error 1

I found /usr/lib/libmupdf-third.a, so I guess a hyphen was added
somewhere along the way? After this Makefile patch, it builds and runs.

Maybe this should be removed from aurweb? Upstream didn't do something in a while and it cannot be compiled against mupdf 1.12
