I solved it so: asm/ioctl.h: ............... /* used to create numbers */ #define _IO(type,nr) _IOC(_IOC_NONE,(type),(nr),0) #define _IOR(type,nr,size) _IOC(_IOC_READ,(type),(nr),(_IOC_TYPECHECK(size))) #define _IOW(type,nr,size) _IOC(_IOC_WRITE,(type),(nr),(_IOC_TYPECHECK(size))) #define _IOWR(type,nr,size) _IOC(_IOC_READ|_IOC_WRITE,(type),(nr),(_IOC_TYPECHECK(size))) #define _IOR_BAD(type,nr,size) _IOC(_IOC_READ,(type),(nr),sizeof(size)) #define _IOW_BAD(type,nr,size) _IOC(_IOC_WRITE,(type),(nr),sizeof(size)) #define _IOWR_BAD(type,nr,size) _IOC(_IOC_READ|_IOC_WRITE,(type),(nr),sizeof(size)) ..................... I patched all files that contains next defines: _IOR, _IOW or _IOWR with _IOR_BAD, _IOW_BAD, _IOWR_BAD
Really it is not right. But it would be so if I complie with 2.4.x headers
sizeof(sizeof(anymore)) is sizeof(int). And threre was int. Thus it was right only there.
