Actually libXrender is in the base system, but no dev files of course. I had this same issue when building Xchat. It insisted on the .la file. I was building it against xorg72, and at the time I just compiled my own libXrender and installed it in xorg72 to provide the .la and .a file. That is why I asked earlier about xorg72 including the .a and .la files in the extension. So I am pretty sure if xorg72 is loaded and the pkgconfig stuff set that the compile error would go away. And xorg72 did not end up as a dependency with Xchat

I'd looked in /opt/gnu-utils (from an old gnu-utils) and found libXrender so I assumed that was where it came from, but you're right it's also in /KNOPPIX/X11R6/lib

I'd forgotten I'd submitted xorg72-dev.tar.gz - the .a and .la files for xorg72 are there - this doesn't get round not having the dev files for libXrender in the dsl base, but I never figured out where it came from so I couldn't include the dev files in compile-3.3.5

As you say, you could probably get away with compiling against xorg72 - not exactly the "done thing", but it could well work...

I've not had a chance to do much with this over the weekend, but at the end of last week I loded up xorg72 & the dev.tar.gz - only problem is the tar.gz couldn't load over xorg72,uci as it is read-only. Once I'v managed to extract xorg72 to a r-w filesystem I'll let you know how I go.

My reason for trying to recompile gtkam is that I get nothing but segmentation faults with the version in the repository - especially when trying to start downloading images. Someone else rported this recently & it reminded me to get on with attempting a recompilation with the newest version.

OK,

I've remounted xorg72.uci as rw, mounted the devs - managed to recompile libXrender so I have the .la files. Got libusb, libexif, libexif-gtk,libgphoto2, & gphoto2, compiled & installed. Now trying to compile gtkam. the configre script exits ok:

Code Sample

Configuration (gtkam 0.1.15):

Build
Source code location: .
Compiler: gcc

Features
Use translations: yes
libgphoto2: yes
bonobo support: no (bonobo-activation, bononoboui libs)
Gnome support: no (gnomeui lib)
GTKAM_C_IDENTIFIER: file:$(datadir)/gnome/help/gtkam/C/gtkam.xml
Gimp support: no
libexif: yes
libexif-gtk: yes

You may run "make" and "make install" now.

BUT.... make fails:

I've used the latest version of compile.3.3.5 from the testing area & gtk 2.10.9 + the dev headers for that version as well.
