Migrating `libCombine` to zipper 3.x
In order to update zipper package in Fedora to use this version, I need to update the dependents, which afaict is only libCombine. I have got some pieces figured out, but then I was hit with
/builddir/build/BUILD/libCombine-0.2.20-build/libCombine-0.2.20/src/combine/combinearchive.cpp:301:31: error: ‘class zipper::Unzipper’ has no member named ‘extractEntryToStream’
301 | bool result = mpUnzipper->extractEntryToStream(filename, tempStream);
The symbol is there, but apparently it is not exported to the header file. https://github.com/Lecrapouille/zipper/blob/3938d0a5bd611997f1e9ac12fbf8ee90a6ce9499/src/Unzipper.cpp#L873-L874
Can you offer some assistance for such a transition?
@LecrisUT Ok I'll give a look. I'm currently testing CMake I'll commit all tickets soon.
@LecrisUT By the way, why not using the my makefile ? It can now create RPM

When creating the RPMs in Fedora, we have to do our own changes, and the build process is continuously being optimized for cmake, meson, etc. support, but not for Makefile because those are not standardized. If the makefile is used to compile the code instead of CMake, there are numerous other problems.
Hum ! Ok let's talk about MyMakefile later. I just committed fixes concerning to your other issues. I'll investigate this one. My fork have API changed.
@LecrisUT I've not tried yet to compile but the new new name is simply extract
Ok, I think I got the interface all re-mapped and everything compiled. But the testsuite is failing, so I hope I can leave it to you
I cannot compile libcombine
cmake .. -DLIBSBML_INCLUDE_DIR=/usr/local/include -DLIBNUML_INCLUDE_DIR=/usr/local/include
make
I have issues with linker bzfilebuf, LibXMLParser I have libxml2 already installed. I did not understand about EXTRA_LIBS=xml2;bz2;z;iconv
Yes, there are a lot of weird incompatibility issues in their build-system. I will report them later. For now, you can use the following as a reproducer
FROM fedora:latest
# Basic build tools and compilers
RUN dnf install -y \
cmake ninja-build git \
gcc-c++
# libCombine dependencies
RUN dnf install -y \
libsbml-devel bzip2-devel libxml2-devel
# Get the projects
RUN <<EOR
mkdir /projects
pushd /projects
# Do not recurse-submodules libCombine. They are doing some weird stuff with that
git clone \
-b zipper-3.0 \
https://github.com/LecrisUT/libCombine
git clone \
-b cmake/modern --recurse-submodules \

# Enable C needed by FindLIBXML.cmake
sed -i "s/LANGUAGES CXX)/LANGUAGES C CXX)/" libCombine/CMakeLists.txt
# sbml is linking to minizip also. Use the version that it was installed with
dnf install -y minizip-ng-compat-devel
EOR
# Configure and build the projects

If you need a primer on how to build and enter the container
$ podman build -t debug:libCombine -f Dockerfile
$ podman run -ti debug:libCombine
[root@b33379179da2 projects]# ctest --test-dir build-libCombine --output-on-failure
