Often times Linux distros will ship without /usr/local/lib in the ld
path, so running ldconfig won't actually pick up libraries there. Edit
/etc/ld.so.conf and add a line for /usr/local/lib then run ldconfig
again.

You might want to check if there is a libjson.so present (maybe in /usr/lib) from a different json library.  Unfortunately more than one project used the same library name so sometimes they can conflict.

Do you have a fix for this yet?  I've also been having this issue and am unable to find a solution.

Thanks

Still having the issue. Since I was using ec2 .. I even tried installing from scratch several times ... doesn't make sense at all to me.. some think small is causing this  issue not go away.

I am running my server without geojson Support which depends on json-c

Is there else we can try..

Lemme know how it goes for u...

[Eric Haszlakiewicz]

Installing from scratch won't help you at all if you have a conflictling library installed.  You need to either *un*install the other library, or adjust how you link your program to pick things up in a different order.  (i.e. pass -Wl,-R when linking and/or set LD_LIBRARY_PATH)

Greetings, I resolved this error installing json-c-devel, then ldconfig.
Hope this help you.

Good day.
