Been trying to upgrade tesseract through sbopkg, which fails as libpng16.la cannot be found in /usr/lib64 and it be right there is no such file there or in /usr/lib - can anyone help?
My Leptonica version is 1.82.0; the SBo verion of Tesseract is 5.0.1; I am also FYI using Slackware 15.0 64 stable, having been forced to upgrade from 14.2 64, not a fresh install.
Just looked at the Tesseract.slackbuild file on slackbuilds and as far as I can see it points to the correct version.
On the terract github page/space the latest version is 5.1.0, so I will download and adjust the SBo build script accordingly.
I looked in my lib64 directory and linpng.la points to libpng16.la which is not there; I also reinstalled libpng using slackpkg - still no joy. Have just inserted the downloaded libpng16.la into lib64, will see what happens.
Guess what now the complaint is about libgif.la not being found - well I have run out of patience and time for now - but thanks for the filw as it worked.
Since a lot of time the .la files are not used anymore in Slackware.
You should delete all of them in your system (in /usr/lib64).
If some exist the compile process could have some problems like you have.

Hi folks, and welcome to the third ever Slackware Mass Rebuild (and the
longest ChangeLog entry in project history). There were two primary
motivations for rebuilding everything in the main tree. The first was to
switch to the new C++ ABI. The second was to get rid of all the .la files
in the LD_LIBRARY_PATH. Really, having .la files installed has been mostly
obsolete since things began to use pkg-config instead, but it's not easy
to get rid of them unless you do it all at once. If you just take them out
of one package, any other packages containing .la files that refer to the
removed ones will be broken. We've removed a few here and there before
(and then handled any packages that had referred to them with a rebuild),
but it was time to finally remove all the ones in /lib{,64} and
/usr/lib{,64}. One of the reasons that this really needed to happen is that
many projects are starting to migrate to build systems other than autotools,
and those systems do not generate .la files. So if we didn't get rid of them
now, we might end up in a situation later on where they are being removed
by upstream and then we would have to chase down the dependency breakage and
recompile (possibly many) other packages. The .la files that are outside of
the LD_LIBRARY_PATH were not removed (and shouldn't be) - those ones are
often used by the lt_dlopen() function to load plugins and removing those
ones can break things. But those ones don't cause problems... they aren't
likely to try to infect .la files produced by other packages.
IMPORTANT NOTE: If you have any third party or other packages installed on
your system that don't come with Slackware, and those packages have installed
any .la files, it is very likely that they refer to some .la files which we
have just removed, and that trying to compile against these packages will no
longer work. Luckily, the solution is simple: remove them. This command will
remove any stale .la files from the LD_LIBRARY_PATH:
rm /{,usr/}lib{,64}/*.la
Moving forward, nothing shipped in Slackware will contain any .la files in
those directories, and any SlackBuilds intended to be used with Slackware 15.0
should contain this bit of script:
# Don't ship .la files:
rm -f $PKG/{,usr/}lib${LIBDIRSUFFIX}/*.la
Just for everyones information, I was able to install tesseract version 5.0.1 from the SBo repository, but not the 5.1.0 version using the the same but version number diffrence in the slackbuild script; brunes help worked.
