Dear Stef,
Thanks a lot for a provided example. From your code I have made a program (see
attachment) whichcompiles. However, I can not link it with the libsane-genesys.
apparently I miss something.
I have compiled SANE libraries as following:> export BACKENDS=genesys> export
CFLAGS="-D UNIT_TESTING"> ./configure --prefix=.....
The program compiles perfectly as:> gcc -I ./compile/include/ -I
./compile/backend/ -c tst_scan.c
But when trying to link against libsane-genesys library gcc complains:> gcc -I
./compile/include/ -I ./compile/backend/ -L ./local/lib/sane/ -l sane-genesys
tst_scan.c -o tst_scan/tmp/cc958m4x.o: In function `sanei_debug_genesys_call':
tst_scan.c:(.text+0xad): undefined reference to `sanei_debug_msg'

tst_scan.c:(.text+0x32c): undefined reference to `gl843_begin_scan'
tst_scan.c:(.text+0x33f): undefined reference to `sane_strstatus'
tst_scan.c:(.text+0x3b8): undefined reference to
`sanei_genesys_read_data_from_scanner'
tst_scan.c:(.text+0x3d4): undefined reference to `gl843_end_scan'
tst_scan.c:(.text+0x3e7): undefined reference to `sane_strstatus'
tst_scan.c:(.text+0x42b): undefined reference to `sanei_genesys_write_pnm_file'
tst_scan.c:(.text+0x45b): undefined reference to `sane_genesys_close'
tst_scan.c:(.text+0x460): undefined reference to `sane_genesys_exit'
If I try to use libtool, it complains that I am linking against loadable module
Apparently I am doing something wrong.Please let me know what is the proper way
of compiling a unit testing program.
Thanks a lot,Myroslav
