Re: [osg-users] [build] Build problem with gdk-x11-2.0

Re: [osg-users] [build] Build problem with gdk-x11-2.0
Hi Davin,
I have just checked my CMakeCache and I too have POPPLER_LIBRARY_DIRS
rather then POPPLER_LIB_DIRS that I used in the pdf/CMakeLists.txt.
So it does look like POPPLER_LIBRARY_DIRS is the one to use. I've
made this change and checked into svn/trunk. The file is also
attached.
Could you let me know if this change helps.
Cheers,
Robert.

Hi Robert --
My CMake-foo is weak, so a bit of hand-holding is appreciated in finding the
info you seek.
Agreed whole-heartedly with your comment about the right way to fix the
problem I encountered -- my low comfort level with CMake led me to stumble
onto the quick and dirty workaround I described.
What I can offer is this:
* in the svg plugin, the libgdk*.so libraries appear to be successfully
referenced and linked in as seen in that plugin's link.txt where
-L/opt/gnome/lib64 appears in the CMake-generated version of that file
(i.e. I didn't touch that one at all)
* in the problematic pdf plugin's CMakeLists.txt, I see POPPLER_LIB_DIRS
referenced like this:
LINK_DIRECTORIES(${CAIRO_LIBRARY_DIRS} ${POPPLER_LIB_DIRS})
* looking in the top-level CMakeCache.txt, I can find no such
POPPLER_LIB_DIRS definition however I do find that both POPPLER_LDFLAGS and
POPPLER_LIBRARY_DIRS contain references to /opt/gnome/lib64 (the link
directory I needed for the pdf plugin to build on my particular system) in
their definitions; in particular, this line:
POPPLER_LIBRARY_DIRS:INTERNAL=/opt/gnome/lib64
I do not know if POPPLER_LIB_DIRS should be replaced with
POPPLER_LIBRARY_DIRS, but I hope the above proves helpful.
Please guide me to dig for more information -- I'm happy to help.
Davin

Yes that looks like a simple typo. Replacing POPPLER_LIB_DIRS with POPPLER_LIBRARY_DIRS should fix your problem (can you confirm that?). Apparantly not a lot of people build this plugin without it being located in /usr/lib otherwise someone would have caught this earlier. What you're seeing is the result of a function call into CMake's FindPkgConfig module made in the root CMakeLists.txt of OSG (search for POPPLER). The function provides PACKAGE_LIBRARY_DIRS: http://www.cmake.org/cmake/help/cmake2.6docs.html#module:FindPkgConfig -- Philip Lowman ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [build] Build problem with gdk-x11-2.0
Hi Davin, One should use CMake to set up the paths correctly rather than have to edit the link.txt, so the fact you needed to do this suggests that either the required libs were found correctly, or that the pdf/CMakeLists.txt is missing a search path. What values does Cmake report for the gdk libs? Robert.

Do you have the libgdk development packages installed for your distribution? There should be a libgdk-x11-2.0.so symbolic link (without .0) somewhere in /opt/gnome/lib64 along with header files. On Linux systems build systems like automake and CMake never search for versioned shared libraries directly but rather resolve the symbolic link libfoo.so=libfoo.so.1 to know that libfoo.so.1 is needed at runtime. Development packages that provide header files usually provide .so symbolic links or just plain .so files if versioning is not being used. OSG's cmake scripts should probably be telling you about this problem at configure time (this may be a build system bug). -- Philip Lowman ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
