[sane-devel] bug report: ptal configure check

[Walter Hofmann]

Hi, 

I noticed that the configure check for ptal in sane-backends-1.0.7 fails
with the following error:

wh at aragorn:~/tmp/libsane$ gcc -o conftest -g -O2 -W -Wall 
-D_GNU_SOURCE -I/usr/local/include  -L/usr/local/lib conftest.c -lptal

libptal is /usr/lib/libptal.so.0.1 from the Debian hpoj 0.8-11 package.

As you can see, adding -lcrypto solves the problem.
