I have found 2 problems regarding the abovementioned backend in Mandriva 2005 LE (Mandrake 10.2), and they affect both the "direct" and "kernel module" access methods to my parallel port scanner (a BrightScan OptiPro, which is a rebadged Plustek PT12):
1. Scanning never takes place unless I set warmup time to 0 (zero) seconds. The last line in the debug output is related to the warmup time (the program seems unable to perform a simple countdown starting at any number of seconds!);
2. The scanner "hangs" unpredictably after scanning some pages, or particularly when the current settings result in big output files (bigger than 2 or 3MB).
3. Compiling the kernel module fails due to the new gcc 3.4.3 (the "inline" functions result in an unrecoverable compilation error).
Well, after scanning the archives of this mailing list, and experimenting myself with the source code of the backend, I found out how to get this backend to function properly with Mandriva 2005 LE:
1. Visit any download mirror of Mandriva, and browser the FTP directory structure until you find the source rpm for sane. Save it to your computer:
sane-1.0.15-7mdk.src.rpm
2. Become root (type "su" in a terminal) and install the source rpm:
rpm -ivh sane-1.0.15-7mdk.src.rpm
3. Change to the sources directory:
cd /usr/src/RPM/SOURCES
4. Unpack the sane-backends source code:
tar -jxvf sane-backends-1.0.15.tar.bz2
5. Enter the backend source code subdirectory:
cd sane-backends-1.0.15/backend
6. In order to fix the GCC 3.4.3 compilation error, edit the file plustek-pp_procs.h and modify line 81:
from
# define _INL inline
to
# define _INL
7. In order to fix the timer (warmup) problem, and possibly the "hang" problem in the motor driver with particular scanning settings or file sizes, edit the file "plustek-pp_misc.c" and modify the following lines:
Line 604
From
_LOC _INL void MiscStartTimer( pTimerDef timer , unsigned long us)
to
_LOC void MiscStartTimer( pTimerDef timer , unsigned long us)
Line 623
From
_LOC _INL int MiscCheckTimer( pTimerDef timer )
to
_LOC int MiscCheckTimer( pTimerDef timer )
8. Don't forget to save changes to the edited files
9. Change again to the SOURCES directory:
/usr/src/RPM/SOURCES
10. Remove the old sane-backend source tarball:
rm -f sane-backends-1.0.15.tar.bz2
11. Recreate it from the modified source code:
tar -jcvf sane-backends-1.0.15.tar.bz2 sane-backends-1.0.15
12. Rebuild the binary as well as the source packages:
rpmbuild -ba /usr/src/RPM/SPECS/sane.spec
13. After the build process is complete, reinstall your libsane1 and sane-backends packages from the newly compiled binaries, for your apropriate architecture, located at
/usr/src/RPM/RPMS
For example, the binaries for my Pentium4 machine were created at:
/usr/src/RPM/RPMS/i586
In order to reinstall them, I have first removed the old packages with "rpm -e --nodeps sane-backends libsane1" and then reinstalled them from the location above ("rpm -Uvh libsane1-1.0.15-7mdk.i586.rpm sane-backends-1.0.15-7mdk.i586.rpm")
14. Restore sane configuration files from the "rpmsave" files:
cp -f /etc/sane/dll.conf.rpmsave /etc/sane/dll.conf
cp -f /etc/sane/plustek_pp.conf.rpmsave /etc/sane/plustek_pp.conf
15. First test the scanner with "option warmup 0" and then try another warmup values. It should work now.
