[sane-devel] Re: strange rattle in epson 610 / compile problem 1.0.14 on slackware 9.1

[Kees Lemmens]

Hi,

My problem compiling sane-1.0.14 under Slackware 9.1 is solved :

Someone added gphoto2 to the default libraries since 1.0.14 !

However, "configure" found libgphoto2 because of an old gphoto2-config in
/usr/local/bin but WASN'T able to find libgphoto2.so at compile time !
This made the test compilation for getenv, strdup and others fail, thereby
making it completely impossible to install the backends.

What should be improved IMO :

configure should only decide to use libgphoto2 if it is able to compile and
link a program using these libraries and it should disable gphoto2 in all
other cases. Relying on the presence of gphoto2-config is not enough IMO.

For now I configured using :

./configure --prefix=/opt/sane-1.0.14 --without-gphoto2

BTW: sane-1.0.14 works fine now ;)

Bye,
Kees Lemmens.
