I'm fairly new at Gentoo, so I hope I get this right. Please forgive & correct any trangressions and misunderstandings so I can learn :-) I tried to emerge vlc a few times with the same result "vlcintf.idl:3: can't open included file nsISupports.idl for reading". Eventually I was able to get it working with a little grunt work. I didn't have a -I /usr/lib/mozilla/include/idl or a -I /usr/share/idl/mozilla directory as the errors suggested, so I created them. On my system all the .IDL's were in /usr/lib/mozilla-firefox/idl (This is not in the -I's.) I had to cd into the created /usl/lib/mozilla/include/idl and do a cp /usr/lib/mozilla-firefox/idl/*.idl . This allowed vlc to compile cleanly, but has left .IDL's in a directory that was not in the firefox ebuild. I see this as a risk should Firefox ever be updated. I have now removed all these "temporary" copies of the .IDL's to ensure I don't emerge --update sometime in the future with bad files. This will break any future recompile of VLC but this is better (IMHO) than leaving them there. How do I modify things so /usr/lib/mozilla-firefox/idl becomes a -I at this point? Or am I going about things the wrong way, is something on my system or a misunderstanding of the way things work causing the error? Reproducible: Always Steps to Reproduce: 1.emerge vlc 2. 3. Actual Results: /usr/bin/xpidl -I/usr/share/idl/mozilla \ -I/usr/lib/mozilla/include/idl \ -m header -o vlcintf ./vlcintf.idl ./vlcintf.idl:3: can't open included file nsISupports.idl for reading Expected Results: vlc should emerge cleanly without having to copy .IDL's into a valid include directory. In my case at least /usr/lib/mozilla-firefox/idl should also be an include directory.

0.8.1-r1 requires the complete mozilla suite and *should* build against that fairly well if they haven't changes locations or other similar things. If you want it to work fine, it's anyway suggested to use 0.8.2-r1 instead, as that builds against gecko-sdk.
