Updating the shared library cache automatically using ldconfig

[Richard Crozier]

Dear list,

Please CC me as I am not a subscriber to the list.

I am seeing the same issue as described in this previous post to the 
automake mailing list:

http://gnu-automake.7480.n7.nabble.com/quot-error-while-loading-shared-libraries-foo-so-0-cannot-open-shared-object-file-No-such-file-or-di-td3970.html

The issue is that my program uses a shared library installed by 'make 
install' at the same time as my program, but the shared library cache is 
not updated, resulting in the error

"error while loading shared libraries: foo.so.0: cannot open shared 
object file: No such file or directory"

when you try to run the program. This can be solved by manually running 
ldconfig or rebooting. Mostly my users do not know to do this, so we get 
bug reports. How can I have ldconfig run if necessary after make 
install? What exactly should I put in my Makefile.am or elsewhere to do 
this?

Alternatively, is there an alternative solution, or something else I'm 
missing? There was no update on the previous message since Jan 2008.

Thanks,
Richard Crozier
