Libraries are missing soname

[paolostivanin]

Version: all released versions, included latest stable 1.9.1

The following libraries are missing a SONAME (DT_SONAME) field, which is unfortunate. Programs built with them will not receive proper library requires (DT_NEEDED):

libaltaircam.so
libASICamera2.so
libEFWFilter.so
libUSB2ST4Conv.so
libEAFFocuser.so
libatikcameras.so
libflycapture.so
libmallincam.so
libnncam.so
libpktriggercord.so
libqsiapi.so
libRicohCameraSDKCpp.so
libmtpricoh.so
libsbig.so
libstarshootg.so
libSVBCameraSDK.so

Unfortunately, this is something that only the vendors (ZWO, QHY, etc) can fix.

As a workaround, patchelf --set-soname libstarshootg.so.1 on the packager side is possible.

Thanks!
That worked for almost all libs. I have one last issue with libatikcameras, because it requires libflycapture.so.2:

$ patchelf --debug --print-needed indi-3rdparty-1.9.1/libatik/x64/libatikcameras.bin 
...
libflycapture.so.2
...

I'm using patchelf --set-soname 2 libflycapture.so.2, and it works fine because DT_SONAME is correctly set, but when trying to install libatikcameras2 I get:

unresolvable: nothing provides libflycapture.so.2()(64bit) needed by libatikcameras2

Any idea how I can sovle this @jengelh ?

libflycapture has the correct soname set, so I don't understand why OBS is not picking up the lib correctly (https://build.opensuse.org/package/binary/home:polslinux:teststuff/libindi-3rdparty-libs/openSUSE_Tumbleweed/x86_64/libatikcameras2-1.9.1-17.1.x86_64.rpm)

$ objdump -p indi-3rdparty-1.9.1/libatik/x64/libflycapture.bin |grep 'SONAME'
  SONAME               libflycapture.so.2

found and fixed the packaging issue :) (as always the bug was between the chair and the keyboard)

[jengelh]

When you (re-)set the SONAME on one library, it may be necessary to do --replace-needed in another.

Binary blobs provided by the camera manufacturers. Can't really do much about it besides using patchelf as suggested above.

@knro, would it be possible/feasible that indi-3rdparty does the patchelf (perhaps as part of make install or something)? Then all distributions would benefit.

In case it might be helpful, that's what I've used to find missing/wrong soname:

for f in $(find lib* -type f -name *bin | grep -E 'x64|64' | sed '/arm64/d' | xargs); do echo "=> Checking $f" ; patchelf --debug --print-soname $f; echo "------"; done
