Summary: libsane.la references libgphoto2.la but sane-backends doesn't require libgphoto2-devel Classification: openSUSE Product: openSUSE 11.3 Version: Factory Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Printing AssignedTo: jsmeix@novell.com ReportedBy: vuntz@novell.com QAContact: jsmeix@novell.com Found By: --- Blocker: ---

/usr/lib/libsane.la contains this line:

dependency_libs=' -L/lib -lieee1284 -ljpeg /usr/lib/libgphoto2.la /usr/lib/libgphoto2_port.la /usr/lib/libltdl.la -ldl -lexif -lm -lusb -lpthread'

This means that our toolchain will look for libgphoto2.la when trying to build something depending on libsane.

However, sane-backends (which contains libsane.la) doesn't depend on libgphoto2-devel, so the build will fail.

I don't know if libgphoto2-devel is needed for anything else, but it's possible that it's not. In this case, just removing the .la file would be a simple fix.

Btw, is there any reason to not have a libsane-devel subpackage?

--- Comment #1 from Johannes Meixner jsmeix@novell.com 2010-04-28 09:43:32 UTC --- For openSUSE 11.3 I like to remove /usr/lib[64]/libsane.so and /usr/lib[64]/libsane.la from the sane-backends package regardless that it is unknown how whatever third-party scanning frontend may like to link with SANE (i.e. with the dll meta-backend which is currently /usr/lib[64]/libsane.so.1.0.20).

At least the frontends which are provided by openSUSE /usr/bin/scanimage, /usr/bin/xsane, and /usr/bin/skanlite link with /usr/lib[64]/libsane.so.1 which is a symbolic link which ponts to the actual dll meta-backend library so that the openSUSE scanning frontends neither need /usr/lib[64]/libsane.so nor /usr/lib[643]/libsane.la.

I don't know about libgphoto2. Marcus, do you need /usr/lib[64]/libsane.so and/or /usr/lib[64]/libsane.la?

--- Comment #2 from Marcus Meissner meissner@novell.com 2010-04-28 09:44:58 UTC --- actually libsane links against libgphoto , not the other way round.

i removed the libgphoto2.la too now, and I think you can also remove the libsane.la to reduce such issues further.

--- Comment #4 from Marcus Meissner meissner@novell.com 2010-04-28 11:25:59 UTC --- err, do not remove the .so file(s), but only the .la files!

no programs will ever be able to link against libsane anymore in this case.

--- Comment #6 from Johannes Meixner jsmeix@novell.com 2010-04-28 11:37:43 UTC --- There is or was a nice rpmlint check that complains that plain *.so files (without a trailing version number) are devel files (i.e. not needed for normal runtime operation).

See comment #1: All our scanning frontends link with /usr/lib[64]/libsane.so.1 (note the trailing SANE major version '.1') which is a symbolic link which ponts to the actual dll meta-backend library like /usr/lib[64]/libsane.so.1.0.20 which has the full SANE version number.

You could test it on any installed running system using # mv /usr/lib/libsane.so /usr/lib/libsane.so.away # mv /usr/lib/libsane.la /usr/lib/libsane.la.away and then check if your scanning applications still work.

I still think it is correctly fixed.

Of course please reopen if there is a program which links with /usr/lib[64]/libsane.so

--- Comment #7 from Marcus Meissner meissner@novell.com 2010-04-28 11:40:41 UTC --- of course they still work, the .so is used during building (not during runtime).

it points to the .so.1 file

--- Comment #8 from Johannes Meixner jsmeix@novell.com 2010-04-28 11:47:17 UTC --- Oops! I missed to think about what is needed during building by other packages which need sane-backends to build.

I will re-add /usr/lib[64]/libsane.so
