I want it to be like:

That makes "modules/System/system.la" ok, but it still puts
system.o and system.lo in the top level src directory.
The latter feature is governed by the Automake option subdir-objects.
Note that the option has existed for a long time, but its functionality
has been improved lately, e.g., for non-C sources. See the NEWS file
for details.
Hi,
I forgot about that option.
Look again. That's entirely inconsistent with my experience with
automake's (1.10) behavior. The object file generated from the above
should be "modules/System/modules_System_system_la-system.lo".
Then you have subdir-objects set.
That means the program won't work in the uninstalled state,
because dlopen is looking for system.o as modules/System/system.o.
That seems unlikely. dlopen should be looking for system.so. I don't
imagine it cares about the location of system.o.
I agree with Braden here, dlopen should not care about object positions
and things should work with subdir-objects and without. If you have a
failure setup, please show us how to reproduce it.
I have:
AUTOMAKE_OPTIONS = subdir-objects
System_LTLIBRARIES = modules/System/system.la
modules_System_system_la_SOURCES = modules/System/system.c
modules_System_system_la_LDFLAGS = -module
AM_LDFLAGS = -export-dynamic
and now it works better with:
modules/System/system.la
modules/System/system.lo
modules/System/system.o
generated.
However, the shared object that dlopen requires is in a new .libs directory:
modules/System/.libs/system.o
modules/System/.libs/system.so
modules/System/.libs/system.so.0
modules/System/.libs/system.so.0.0.0
Dlopen fails because it is looking for modules/System/system.so
When installed, i'll have the install location at:
/usr/lib/$(pkglibdir)/System/system.so
Should i just have dlopen look for modules/System/.libs/system.so
and modules/System/system.so and use the first one that succeeds, or
is there a cleaner way for avoiding this?
Also, what's the best way to determine from within the program whether
it is currently installed or not?
