[ts-7000] Problem compiling libfprint with kernel 2.4 on ts-7260

["Daniel" <>]

Hello, in the past I have successfully installed and used libfprint on my 
TS-7260 embedded system with Debian Etch, kernel 2.6.21 and gcc 4. The problem 
is that I need to downgrade to Debian Sarge, kernel 2.4.26 and gcc 3.3.5 so I 
can store my file system in a SD Card and still have USB support in order to 
attach my u.r.u4000 reader. At this point I have compiled and installed libusb 
and openssl0.9.8.c (openssl0.9.7 was installed without libcrypto). I also 
installed imagemagick and glib2.0 from the repositories. The configure file 
runs smoothly, but when I try to compile I'm getting this errors:

:libfprint-0.0.6# make                                              
make  all-recursive                                                            
make[1]: Entering directory `/opt/libfprint-0.0.6'                             
Making all in libfprint                                                        
make[2]: Entering directory `/opt/libfprint-0.0.6/libfprint'                   
/bin/sh ../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..    -fc
mkdir .libs

cc1: error: unrecognized option `-fgnu89-inline'                               
make[2]: *** [libfprint_la-core.lo] Error 1                                    
make[2]: Leaving directory `/opt/libfprint-0.0.6/libfprint'                    
make[1]: *** [all-recursive] Error 1                                           
make[1]: Leaving directory `/opt/libfprint-0.0.6'                              
make: *** [all] Error 2

I have googled this problems but only to found out that it has to do with gcc 3 
(which doesn't support this options). I tryed to patch libfprint, got rid of 
the -fvisibility=hidden problem, but I still don't know what to do with the 
other 2.

Thanks for your help,

Daniel.
