Hello!
I'm preparing a port of a Linux application (Zoom conferencing client).
The vendor (zoom.us) offers RPMs for both x86_64 and i686, which makes
it tempting to just USE_LINUX_RPM. However, that knob unconditionally
turns on the USE_LINUX_PREFIX, which bsd.port.mk says /not/ to use "for
leaf ports (e.g. a game or program)".
Not using the USE_LINUX_PREFIX, poses another challenge. Zoom comes with
quite a few Linux libraries of its own, which are all dumped into a
non-standard location. My port is installing a
/compat/linux/etc/ld.so.conf.d/zoom.conf listing that location, but that
will be ignored unless ldconfig -- a Linux one -- is invoked, wouldn't
it be?
Finally, if I do rely USE_LINUX_PREFIX and the bulk of the port gets
installed under /compat/linux/opt/zoom, there is a problem with the
DESKTOP_ENTRIES -- because they would be under /compat/linux too,
instead of under ${LOCALBASE}.
usr/share/applications/Zoom.desktop
usr/share/mime/packages/zoom.xml
usr/share/pixmaps/Zoom.png
usr/share/pixmaps/application-x-zoom.png
(I think, the current setting of DESKTOPDIR based on PREFIX is incorrect
-- it should be under LOCALBASE instead. But that's a separate story.)
What are my options with this new port?
1. Follow the examples of existing ports (like citrix_ica):
1. Do not use the USE_LINUX_RPM.
2. Do not bother with Linux' ldconfig.
3. Instead of ${LINUXBASE}/etc/ld.so.conf.d/zoom.conf, create the
${PREFIX}/bin/zoom script with LD_LIBRARY_PATH setting. (This
will keep the libraries bundled with Zoom unavailable to other
Linux programs.)
2. An alternative method:
1. Do declare the USE_LINUX_RPM (and set the SRC_DISTFILES to empty).
2. Install the ${LINUXBASE}/etc/ld.so.conf.d/zoom.conf and declare
the USE_LDCONFIG. (This will make the Zoom-libraries available
to other Linux apps.)
3. Explicitly set DESKTOPDIR based on LOCALBASE.
Opinions? Thank you! Yours,
-mi
