Hello, Everyone

I am running Fedora 30 and attempting to build, install & eventually run GIMP from GIT. It builds & installs without error. But when I attempt to run it I get the following:

[steve@afolkey2 bin]$ ./gimp-2.99 ./gimp-2.99: error while loading shared libraries: libjson-c.so.2: cannot open shared object file: No such file or directory

Obviously the error itself makes perfect sense. Fedora 30 has libjson-c.so.4, not libjson-c.so.2

So the question is, why does GIMP compile and install with libjson-c.so.2 not installed, but it won't run. I would assume that if a file that GIMP requires if it is not going to crash is not present, that GIMP would not compile. Also, what can I do to get this to work.

I know that I do not need to compile GIMP from GIT. I just enjoy doing it. I further understand that the issue could be with Fedora 30 or me.

Thank you,

Steven P. Ulrick

Now I feel better. I just installed GIMP from the official Fedora 30 repos and it crashes with the same error:

[steve@afolkey2 ~]$ /usr/bin/gimp /usr/bin/gimp: error while loading shared libraries: libjson-c.so.2: cannot open shared object file: No such file or directory

I wonder if anyone else running Fedora 30 is having this issue.

One of GIMP's dependencies was built against an older version of json-c. Probably libmypaint, but you can find out using lddtree. If you've built that dependency yourself as well (which is likely, otherwise we'd be hearing a lot more about it :) you need to rebuild it.

Yeah, under Fedora 27, I had to compile libmypaint from source to get GIMP from GIT to build. Forgot all about it... Rebuilding now, having made the appropriate changes to get the non-F30 version of libmypaint out of the way. We'll see what happens.

The result is that the Fedora 30 version of GIMP starts perfectly. The version from GIT, recompiled following a "make distclean", does not work. It crashes with the same error.

Hello, Ell

Spoke to soon. I logged out, logged back in and tried again, and it finally started. Strange, since I did "su - steve" in a terminal directly before I tried starting GIMP from GIT. In any even, I can begin rotating pictures from our recent trip to England...

Thank you for you help!
