Just wondering if you ever try to get this running on a web server? I would like to discus this topic with you in more detail, please drop me an email.

Just a suggestion, you'd have already tried it, in case you have not.

Try to put the firefox-dev library path in the /etc/ld.so.conf eg. add the following line to /etc/ld.so.conf
"/usr/lib/firefox" and then do "sudo ldconfig" to make sure the required libraries are accessible and then try it inside mongrel or webrick if there's any luck?

'Cos when I gdb'ed the SegFault, i figured it was not able to find out some firefox library (most probably the libgtkembed.so or something like that.. ) Here's the ldd output with firefox dependencies shown.

$ldd gtkmozembed.so | grep -i fire
libgtkembedmoz.so => /usr/lib/firefox/libgtkembedmoz.so (0xb7e19000)
libxpcom.so => /usr/lib/firefox/libxpcom.so (0xb77e5000)
libxpcom_core.so => /usr/lib/firefox/libxpcom_core.so (0xb75a2000)

In case this helps.

I think that is what I am going to be trying next, Guess is the LD_LIBRARY_PATH issue actually is causing the trouble for you in webrick or mongrel? Will definitely update this once I have some luck with this.

Have you had any luck getting this to run in a web server? I’ve played about with moz_snapshooter and got it working from a command line just fine, but when I try to run it from within a mongrel or webrick server I get a segfault and the whole server dies. Not good

one more caveat. Requires LD_LIBRARY_PATH set to /usr/lib/firefox
