My guess is that LD_LIBRARY_PATH is set to /usr/local/lib. That means that
when gnucash is starting, it looks for shared libraries in /usr/local/lib
before /usr/lib or /lib. My guess is that you have an old version of some
library in /usr/local/lib.
In the absense of LD_LIBRARY_PATH, shared libraries are usually found in
/lib then in /usr/lib. That is, of course, unless /lib is just a symbolic
link to /usr/lib (solaris does this). If you need LD_LIBRARY_PATH to be
set, but you want /usr/lib to be used before /usr/local/lib, set it to
/usr/lib:/usr/local/lib.
To find out which libraries are really getting used, try this. There are
no spelling errors here... In the first one, LD_LIBRARY_PATH is being set
to an empty string. You may need to adjust the path to wherever gnucash is
installed.
env LD_LIBRARY_PATH= ldd /usr/bin/gnucash
env LD_LIBRARY_PATH=/usr/local/lib ldd /usr/bin/gnucash
env LD_LIBRARY_PATH=/usr/lib:/usr/local/lib ldd /usr/bin/gnucash
Of course Linux uses ldconfig(8) to generate a cache of paths to libraries.
This is bad in that it confuses users of other UNIX variants, but is good
in that at startup you don't have a series of system calls that look like:
stat("/opt/foo/lib/libc.so") = -1
stat("/opt/bar/lib/libc.so") = -1
stat("/opt/baz/lib/libc.so") = -1
stat("/usr/local/lib/libc.so") = -1
stat("/lib/libc.so") = -1
stat("/usr/lib/libc.so") = 0
open("/usr/lib/libc.so") = 3
The above would correspond to LD_LIBRARY_PATH being set to
/opt/foo/lib:/opt/bar/lib:/usr/local/lib. With ldconfig's cache, it would
already know where libc is at.
Did I confuse you enough?
