Ok, will try with newer version. Perhaps I was mislead by an old example. Will let you know what the outcome is (but first a short holiday)

We are not succeeding in our effort to compile iipimage against libpng12.so We tried several constructs and finally removed all the stuff that could possible interfere with the libpng version. But the ldd still shows libpng12.so.0 => not found in our minimal setup. Attached the build log. For the moment we go for the build with --disable-png so we can continue. But is there a way to compile iipimage against libpng16 instead of libpng12?

I'm a little bit confused. We build the iipimage on a pre-stage container with the official gcc docker image so we think this independent on what is following. Or am I wrong about that? This in the docker file of the pre-stage container FROM gcc:4.9 as build RUN mkdir /iipimage RUN mkdir /kakadu COPY docker/iipimage /iipimage/ COPY docker/kakadu /kakadu/ WORKDIR /iipimage RUN apt-get update RUN apt-get install libtool RUN apt-get install libpng-dev RUN sh ./autogen.sh RUN ./configure --with-kakadu=/kakadu/v6_4_1-01203N...

Tried again with the RUN apt-get install libpng-dev but the result is the same. Looks like the package is already present with the latest version 1.6.37 Attached the build logs. Also the ldd shows libpng12.so.0 => not found I am not an expert but the libs on Debian Bullseye have names like libpng16.so.0 ....perhaps is that the cause that the linked library is not found ?

We also applied --disable-png and now we have IIPImage Server Version 1.2 so that's fine with us. But if there is a solution for the libpng problem that would be nice. Some suggest that we should install the libpng12 seperately besides the 16 version.

We have %>libpng-config --version shows 1.6.37 Looks like the libraries are in /usr/lib/x86_64-linux-gnu/ with a version 16 number like libpng16.so -> libpng16.so.16.37.0 etcetera The ldd shows a not found off course ldd iipsrv.fcgi linux-vdso.so.1 (0x00007ffd2050e000) libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007fbb94c02000) libpng12.so.0 => not found libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fbb94be5000) libkdu_v64R.so => /lib64/libkdu_v64R.so (0x00007fbb94922000) libpthread.so.0...

This solved the webp issue and it compiles. But the server won't start with the message ./iipsrv.fcgi -v error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory. Looks like we're missing something.
