Problems with libmozjs and xulrunner?

?

In Ubuntu 10.04 you may get an error similar to this:

?

OS Process Error <0.4649.0> :: {os_process_error,{exit_status,127}}
/opt/couchdb/lib/couchdb/bin/couchjs: error while loading shared libraries: libmozjs.so: cannot open shared object file: No such file or directory

This is can be resolved by creating an xulrunner configuration as follows:

?

sudo vi /etc/ld.so.conf.d/xulrunner.conf

Note: To check what XULRunner version you have installed use xulrunner -v

Then add the following lines to the file (You may need to change the library version to match whats installed):

?

/usr/lib/xulrunner-x.x.x.x
/usr/lib/xulrunner-devel-x.x.x.x

Once the configuration files is created and saved, you will need to run ldconfig:

?

sudo /sbin/ldconfig
