Thanks for taking time to debug this. I think you misunderstand me
though. The problem is not building e_fm it is configuring E to build
with eeze mount. Eeze is installed in /opt/e17/lib linked to to
libmount. Now if I run autogen.sh in e's src directory e_mount support
is never enabled. The reason is that the configure test fails with
/usr/bin/ld: cannot find -leeze.
The offending code from e/configure.ac is (line 397-414):
eeze_mount=
EEZE_MOUNT_CONFIG=0
if test "x$e_cv_want_mount_eeze" != "xno" ; then
AC_CHECK_LIB([eeze], [eeze_disk_function],
[
eeze_mount="eeze >= 1.0.999 ecore-con >= 1.0.999"
EEZE_MOUNT_CONFIG=1
AC_DEFINE_UNQUOTED([HAVE_EEZE_MOUNT], [1], [enable eeze
mounting])
AC_MSG_NOTICE([eeze mounting enabled])
],
[
AC_MSG_NOTICE([eeze mounting disabled])
e_cv_want_mount_eeze=no
]
)
else
AC_MSG_NOTICE([eeze mounting disabled])
fi
(note that the presence of eeze + flags, has been determined earlier via
pkgconfig tests).
As I understand this and the autoconf documentation, this is a bit of a
hack to see if libeeze was compiled with mount support by checking if
libeeze contains the eeze_disk_function. The problem seems to be that
AC_CHECK_LIB only uses the standard library path, so if eeze is
installed in /opt/ the test always fails.
