Hi all,
I was trying to dig deeper into a problem where I get a corruption in
e_fm when mounting and removing a usb disk (see
here:http://marc.info/?l=enlightenment-devel&m=132014458110340&w=2 for
details). I found a couple of problems when trying to build e with
different e_fm options.
1. when efl is installed in /opt/ for example eeze_mount is always
disabled because the configure test fails because of a missing
-L/opt/e17 in the compile.
i don't have libmount, so I can't test it. Can you paste config.log of
eeze, please ?
Sorry I didn't make myself clear, this is compiling E, not eeze. Eeze
compiled fine with libmount support. However when I compile E and do
configure it fails the check, the relevant lines of E's config.log are below
configure:15678: checking for eeze_disk_function in -leeze
configure:15703: gcc -std=gnu99 -o conftest -g -O2 conftest.c -leeze
-lpam >&5
/usr/bin/ld: cannot find -leeze
that is strange: the eeze.pc file should have -L/opt/e17/lib -leeze in the
Libs entry.
One possible reason to not have -L***: you have previously installed eeze
in /usr, removed the files manually except /usr/lib/pkgconfig/eeze.pc.
Then installed eeze in /opt/e17, without updating PKG_CONFIG_PATH. So it's
the eeze.pc in /usr/lib/pkgconfig which is used.
So verify first that there is not an eeze.pc file somewhere else

This is because I have eeze installed in /opt/e17 which is not in the
library path and therefore the linker fails. Adding -L/opt/e17/lib to
configure or export LIBRARY_PATH=/opt/e17/lib fixes this and eeze_mount
is enabled. I have not figured out a way of making AC_CHECK_LIB actually
use a non-default library path (mind you as I said earlier I don't
really know anything about autofoo)
Hope this makes it clearer.
Cheers

2. configure help says enable hal device backend is disabled by default,
however I always have it enabled after configure
there is indeed a problem with hal device *backend* (which is actually not
disabled by default), but the variable e_cv_want_device_hal is anyway not
used at all. So I'm wondering why that part of code is still in
configure.ac
hal *mount* is enabled by default, and that's what is displayed in the
configure output:
Preferred Backends:
* device..........: eeze
* hal_mount...........: enabled
* udisks_mount........: enabled
* eeze_mount..........:
I think i've fixed that in svn. Tell me if there's something wrong.
3. when I pass --disable-mount-hal to configure the build of
e_fm_main_udisks fails with the following error:
/usr/bin/ld: e_fm_main_udisks.o: undefined reference to symbol
'e_dbus_method_call_send'
/usr/bin/ld: note: 'e_dbus_method_call_send' is defined in DSO
/opt/e17/lib/libedbus.so.1 so try adding it to the linker command line
/opt/e17/lib/libedbus.so.1: could not read symbols: Invalid operation
no problem here. The symbol e_dbus_method_call_send is in my libedbus. I
don't know what the problem could be. That symbol exists since e_dbus 1.0.
Note that the EFL are not in /opt/ in my case.

4. building after configure with --disable-mount-hal and
--disable-mount-udisks works (after fixing 1 by exporting LIBRARY_PATH).
However the icons for usb-disks never show up on the screen although
they are detected by eeze (messages about detected devices show up in
xsession-errors).
as I do not have eeze_mount, I think that I can't test that. Maybe Mike
could look at that
Vincent
Unfortunately I don't know anything about autofoo, otherwise I would
have sent some patches for 1,2 and 3. If I can do anything else let me know.
Cheers
