Bug 20796 – gphoto2 ebuild uses build-image paths for shlibs

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tobias Klausmann (RETIRED) 2003-05-11 11:36:31 UTC]

gphoto2 refuses to work (Cannot open library), --debug yields (among other stuff):

0.001828 gphoto2-port-core(0): Could not load any io-library because
'/var/tmp/portage/libgphoto2-2.1.1-r2/image//usr/lib/gphoto2_port/0.5.1' could
not be opened (No such file or directory)




Reproducible: Always

can you attach what version of gphoto2 and libgphoto2 you are using and also "emerge info" as the bug report template originally suggested ?

I can confirm the bug with the same releases:

gphoto2-2.1.1-r1
libgphoto2-2.1.1-r2

The problem appeared with the update of gphoto2 and libgphoto2 yesterday, so strangely enough it worked in earlier versions although a short look over the ebuilds didn't bring up any significant changes that might have triggered the problem?
What I updated at the same time, though, was Portage itself, maybe a change in the way portage emerges files triggered the problem? [That was my original idea, but as Tobias seems to use the stable portage this does not seem to be the case if I think about it.]

The problem seems to arise because the library path is set at compile time in the libgphoto2_port part of the libgphoto2 package in libgphoto2-2.1.1/libgphoto2_port/. The library path for the problematic library is set in the Makefile in that directory as a constant:

  -DIOLIBS=\"$(libdir)/gphoto2_port/$(VERSION)\"    (line 129)

With my very, very limited (as you probably realized by now) "make" knowledge I was not really able to pinpoint the problem that seems to come from the way $libdir is set, though.

HTH.

Below is my "emerge info" report just for completeness:

I can confirm this bug too! exactly the same problem here!

[Comment 5 Alastair Tse (RETIRED) 2003-05-16 12:49:51 UTC]

thanks for all your information.

 i think i've tracked down the problem in libgphoto2-2.1.1-r2, could you please re-emerge it and let me know if it fixes the problem? 

[Comment 6 Tobias Klausmann (RETIRED) 2003-05-16 15:41:36 UTC]

It works for me (I only updated libgphoto2, as there's no update available for gphoto2). Remerge of gphoto2 was NOT necessary

[Comment 7 Alastair Tse (RETIRED) 2003-05-16 16:17:39 UTC]

great.

thanks again for your help guys.
