Hi,

Just some comments despite I just installed gphoto2 for the first time.

On my system, the libs were installed at /usr/local/lib/gphoto2*. If
they are in a subdirectory, run-time linking wouldn't work without
setting LD_LIBRARY_PATH.

The SANE jpeg test doen't look in any special directory. It just tries
to include the header and links against a function. If it doesn't find
libjpeg in /usr/local/lib, maybe /usr/local/lib is not mentioned in
/etc/ld.so.conf?

Maybe in the source code "gphoto2/gphoto2.h" and not only "gphoto2.h"
must be included?

Don't know about that...

Can you please post the interesting part of the log file?

Peter Fales <peter@fales.com> is the mainatiner of this backend.
Peter: Would it be reasonable to use gphoto2-config to determine the
LDFLAGS and CFLAGS like it's done for gtk-config in the sane-frontends
package?
