Hi,
Just tried ogdi on bullseye, and I found that its plugin mechanism isn't functional.
How to reproduce: - apt install ogdi-bin - wget http://freefr.dl.sourceforge.net/project/ogdi/OGDI_Test_Suite/3.1/ogdits-3.1.0.zip - unzip ogdits-3.1.0.zip - ogdi_info -u gltp:/vrf/./ogdits-3.1/data/vpf/vm2alv2/texash
It outputs: ECSERROR: Could not find the dynamic library "vrf"
Now do: ln -s /usr/lib/ogdi/libvrf.so /usr/lib
and retry, and it will output a long listing with the dataset content
The plugin loading mechanism is at https://github.com/libogdi/ogdi/blob/de0189d5447acaf438a9e7866b906aa75ea8f51f/ogdi/c-api/ecs_dyna.c#L86
and relies on a MODULES_PATH #define that defaults to "/usr/lib/ogdi/" but is actually overwritten at https://github.com/libogdi/ogdi/blob/2b431a9bca962fe78d89c0283df95fcaf870dd71/ogdi/c-api/makefile#L31
with -DMODULES_PATH="\"$(INST_LIB)/ogdi/\""
And in https://salsa.debian.org/debian-gis-team/ogdi-dfsg/-/blob/master/debian/rules#L31
configure is called with --libdir=$(CURDIR)/debian/tmp/usr/lib
Looking at the content of libogdi.so confirms that the search path is actually the temporary build directory:
$ strings /tmp/libogdi.so.4 | grep "/usr/lib" /build/ogdi-dfsg-7e7JrZ/ogdi-dfsg-4.1.0+ds/debian/tmp/usr/lib/ogdi/%s /build/ogdi-dfsg-7e7JrZ/ogdi-dfsg-4.1.0+ds/debian/tmp/usr/lib/ogdi/lib%s.so
Now that I remember, I actually hit that issue a long time ago, but failed to report it, and probably just did the ln -s workaround.
I guess the issue might have started from https://salsa.debian.org/debian-gis-team/ogdi-dfsg/-/commit/5b7c9c0b1d1c21c1a551cbad130828c86818a51b since before --libdir was not overridden.
A potential solution could be to add a patch to ogdi/c-api/makefile to remove -the -DMODULES_PATH= override.
Cheers,
Even
