Extension Development :: pkgconfig



When I try to compile using the cairo-1.2 extension make fails compiling the libexif-gtk library with the message:

I had encountered this before your explanation of your compiling method. I have checked this under 3.11 using a base frugal installation and only cairo1.2, gtk+-2.10, xorg72 * compile3.3.5. I redid the symlinks in /opt/bin to point to the fc & freetype files in cairo.

- I believe this is because libcairo is trying to use the freetype/fontconfig libs in the base dsl. You could try either:

1. Move "/opt/cairo-1.2/lib" above "/usr/lib" in /etc/ld.so.conf and then "sudo ldconfig"

or

2. [Brute Force method] delete the freetype/fontconfig libs in /usr/lib then "sudo ldconfig"

..and then try make again.

BTW, once compiled, the gtkam *uci I made starts up without touching /etc/ld.so.conf or deleting the freetype/fontconfig libs in /usr/lib
OK,

Finally got it compiled. Then got the error:

Code Sample
dsl@box:/opt/gtkam/bin$ gtkam
gtkam: relocation error: /opt/gtk+-2.10/lib/libgobject-2.0.so.0: undefined symbol: g_regex_unref

when I ran it. Sorted this by moving /opt/gtk+-2.10/lib above /urs/lib in ld.so.conf & running ldconfig.

Now to try a reboot......

does the same - still need to edit ld.so.conf
I had been starting gtkam with "LD_LIBRARY_PATH=/opt/gtkam/lib /opt/gtkam/bin/gtkam" and did not get this error, but you could try "LD_LIBRARY_PATH=/opt/gtkam/lib:/opt/gtk+-2.10/lib /opt/gtkam/bin/gtkam" or put symlinks to /opt/gtk+-2.10/lib/glib2* in /opt/gtkam/lib
Juanito - thanks for all the help. An update version of gtkam should be in testing soon - along with gnokii.
