Since few people will want to rebuild the plugin - and almost everyone has Firefox installed - it doesn't seem worthwhile to put full Gecko SDKs in the tools directory. > To build OOPHM on Linux if you Firefox installation is at >> /opt/local/firefox (default is /usr/lib/firefox): >> cd plugins/xpcom >> make FIREFOX_LIBS=/opt/local/firefox >> > > Does this only need the regular Firefox distribution, or are additional > files needed? > Only the regular Firefox distribution. The file gecko-sdks.tar.gz (attached to the previous email) contains the required headers and libraries that aren't included in the regular Firefox distribution.
