- Add Makefile.common
o A new build/install system for gecko ports, Makefile.common
includes many generic routines and common tasks.
o Fix ld-run-path in all gecko's by using -Wl,-rpath,${moz_libdir}
thus removing the need to have a startup script for ports that
depend on gecko. [2]
o Use system libm, nss, nspr in all gecko ports
- Add bsd.gecko.mk
o This is the predecessor to WITH_MOZILLA=[mozilla|firefox|...]
with a more robust way of detecting a gecko a end user wishs to
use.
o bsd.gecko.mk abstracts the selection of gecko-based backends. It
allows users and porters to support any available gecko backend
without needing to build many conditional tests. ${USE_GECKO} is the
list of backends that your port can handle, and ${GECKO} is set by
bsd.gecko.mk to be the chosen backend. Users set ${WITH_GECKO} to the
list of gecko backends they want on their system.
Port Makefile example:
USE_GECKO=firefox mozilla seamonkey thunderbird
.include <bsd.port.pre.mk>
.include "${.CURDIR}/../../www/mozilla/bsd.gecko.mk"
End user example:
WITH_GECKO=seamonkey firefox
We highly recommend moving away from using WITH_MOZILLA and switching to
USE/WITH_GECKO.
