c - building DLL based on libzip-static.lib - Stack Overflow

Within the libzip.sln solution there are also derivitive projects like ziptool and zipmerge, which each are EXE projects. I succeeded copying such a project and renaming it (why isn't that a VS feature?) by manually editing the XML of the vcproj file copies and can therefore create a separate new tool as another derivitive work. There's just one problem: The tool projects all are exe projects, chaging the configuration type from exe to dll ... More on stackoverflow.com

How to use static library libzip.lib in a new DLL project | Tek-Tips

January 13, 2025 - github.com To be precise, these projects build from the get go with no problems in their VS2022 version (at least, I assume also in older VS versions). Very nice. Now I thought it's easy enough to take libzip.lib and build a new DLL project using that and offering two simple functions a) ZipDir to zip all files of a directory (recursive with subdirectories) and and b) UnZip a zip file to a target directory.

This is not an MCVE ([SO]: How to create a Minimal, Reproducible Example (reprex (mcve))).

The statement "think that's because of the mismatch of C++ and C (zlib and libzip are C projects)" isn't backed up by anything, and if things are done right, there should be no problem.

2 key aspects to be considered. A VStudio project:

Can "belong" to multiple solutions (there can be an M:N relationship between solutions and projects, and not 1:N (like people might be tempted to think))
Must be properly configured. It can be trickier when:
- Using external artefacts (libs, headers, ...). I explained this (pretty well, I'd say) for OpenSSL: [SO]: How to include OpenSSL in Visual Studio (@CristiFati's answer), so I won't do it again here
- Having multiple platforms / configurations. Might check [SO]: Excel VBA, Can't Find DLL Entry Point from a DLL file (@CristiFati's answer)

Working on the following structure:

code00.sln:
1. libz-static.vcxproj (from zlib-win-build (build-VS2022))
2. libzip-static.vcxproj (from libzip-win-build (build-VS2022))
3. dll00.vcxproj (uses the previous 2)
4. app00.vcxproj (dummy wrapper app to test the .dll)
