Library versioning

2008-01-30 Thread David Paleino
Hi *, I'm packaging a software for the Debian-Med group (CCed), and found that, even if the library is at version 2.2.1, the compilation makes a libfoo.so.2.0.2 [1]. This is due to the fact that in Makefile.am upstream (CCed) has set: libvista_la_LDFLAGS = -version-info 2:2:0 As already discusse

If that one person isn't willing to deal with it then that person shouldn't be writing libraries. :) Never said that... I will take a look into debian-mentors, but I've just talked to the upstream author and can now explain the reason of his choice. Unfortunately that doesn't make

It's a single headache for the one library developer/packager, as opposed to headaches for _every user_ of the library. Yes indeed, but it's still a headache for one person ;). You might want to have a look at the debian-mentors archives, too. I believe this sort of thing gets discussed th

Thanks for that one, the thing is that the upstream author is using libtool which has a somehow "special" versioning method. Apparently when the library's interface changes in a way backwards-compatibility is broken, the major (what they call current) version must be incremented. I will have

Hello, I'm actually making some .deb packages out of a single source archive. One of them should contain a shared library. The upstream author's package's version is 5.13 and the soname of his library has been set to 513. After having contacted him, he told me that was done because apparently
