Dear maintainers,
In Ubuntu, we have upgraded to glibc 2.34 which results in orthanc failing
to build from source, because it includes a test that tries to dlopen()
libdl.so and in glibc 2.34 libdl.so no longer exists, its functionality
having been rolled into libc6. To fix this test, orthanc will need to
dlopen some other library.
Attached is a patch which switches the test to dlopen libmemusage.so
instead, which is also provided by libc6-dev so should always be available.
Please consider applying this patch or a similar one in Debian.
This is obviously not critical in Debian yet, since experimental still only
has glibc 2.33.
Cheers,

+Description: fix compatibility with glibc 2.34
+ In glibc 2.34, libdl.so no longer exists because the shared library has been
+ rolled into libc.so. This causes the dlopen tests to fail. Use
+ libmemusage.so instead, which is also provided by libc6-dev.
