Hi all,
In backends/plustek-usbshading.c, in function usb_GetNewOffset, there
is
if( pcOffset[dw] >= 0 )
pcOffset[dw] is defined as char. On some architectures (at least arm,
powerpc and s390), char is per default unsigned on. This causes a
warning on compilation ("warning: comparison is always true due to
limited range of data type"), and may cause some errors at run time.
I have made a small patch, but I am not sure it corrects everything.
Regards,
Aurelien
