What could be the problem ,i came to see that the sem
has
incomplete type in mmu.h file in asm directory.It was declared as
struct
semaphore.Does it was an incomplete data type for the sem
variable.Please help
me to resolve this problem.Do i require any packages,i have downloaded
the snapgear 3.1.1 and tool chain i386-linux -tools for i386 based
arch.
With best Regards,
Sudheervemana.
