So I would like to ask whether it would be an option to switch the proj library to version 6 for Leap 15.2 ? It is always possible to use proj6 as a replacement of version 4.9.3 using the -DACCEPT_USE_OF_DEPRECATED_PROJ_API_H compiler invocation, so this should have only marginal implications.
I'm okay with that. It is how I have been using it locally on my Tumbleweed system.
Isn't it possible also to have both proj4 and proj6 installed? Perhaps using alternatives? That way existing installed programs can continue to work. And proj7 is also out with additional API/ABI changes.
Yes, of course, one could provide a separate libproj12 package, that would be no problem from a user perspective. But on the package building side, some modifications could be needed, although they are are trivial: If a package is not prepared for proj6 in the configure scripts, one needs to set CFLAGS="$CFLAGS -DACCEPT_USE_OF_DEPRECATED_PROJ_API_H" or similar in the spec file. On my box, the following packages need proj: libgeotiff2 libspatialite7 octave-forge-octproj There are probably some more (how to check for this?), and several packages in home projects would be affected. I did not check, but I guess the ACCEPT_USE_OF_DEPRECATED_PROJ_API_H quirk is probably removed in proj7. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
