Minor version in libproj DLL suffix for MinGW #4151

Closed visr closed 2 months ago

visr commented 4 months ago

Hi, I help to maintain a PROJ build for Julia, used in Proj.jl. These builds are cross compiled to the MinGW target, resulting into DLLs with the minor version in the name; libproj_9_4.dll. This is implemented in ProjVersion.cmake and ProjUtilities.cmake. With this DLL naming new GDAL builds are required for each minor PROJ release, also if they have the same SOVERSION.

Looking at GDAL I get libgdal-35.dll, a suffix with the SOVERSION, implemented in https://github.com/OSGeo/gdal/pull/5701.

Would such behavior also make sense for PROJ?

Making those unique names based on xx.xx.xx versions is a source of problems (as the present case showed) and a waste. I find my disk full of DLL old versions in artifacts dir that never get removed. I've been building GDAL and PROJ for years with VS (to use in GMT) and I never changed the name of the DLL and also we never had a problem because of it. So, yes, please adopt a scheme where the DLL names change the least possible.
