Hi,
I had couple of dummy drivers and kernel modules running on RH 7.3 and kernel version 2.4.18-3... laterly i upgraded to RH 9 and the version is 2.4.20-8. When I compile th moudles on the latest verison, I m getting lots and lots of compilation erros. Could somebody let me knw whts the issue.
Attached is the compilation erros:
