Hi,
if you get an compilation error on kernel 2.6.22 with mISDN from git, try the following, which worked for me.
Open with your favorite editor the file: mISDN/include/linux/isdn_compat.h
Than change the following line:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,22)
#define MISDN_COMPAT_KMEMCACHE
#endif
To:
#if LINUX_VERSION_CODE <= KERNEL_VERSION(2,6,22)
#define MISDN_COMPAT_KMEMCACHE
#endif
Note: Its just a replacement from "<" to "<=", the other 2 lines stay as they are.
Bye
Sven
