Hi there,
it has been reported, that there are compilation
problems on glibc2.2 based systems (especially SuSE 7.2)
As I don't have such a system, I can't test my solution but I
have one for you.
I'd be glad to hear from you - please test.
Replace the makefile of the driver in the plustek_driver
directory with the one I have attached (only version 0.39!!!)
and try
make clean
make all K24=y
This enables the glibc2.2 specific stuff! Alternatively you can
enable the switch within the makefile - simply uncomment line 33
Hope this helps to solve your problems...
Gerhard
