HI
i am using the following flags, which is nothing but rtl.mk file which is
auto mativcally generated by
RTLInux Make file.
i am sending my make file at the end.
Could u pls tell me whether can i use this as it is.
i tried by removing optimization option, -O2. then i its compiled
fine.
and when i was trying to insert the module, its giving some
errors like unresolved syblos related to thread attibutes, and its not
yet all loading
into the kernel.
and i also included my make file after this.
Could u pls any one tell me what are the things i have to remove from this
CFLAGS list,
to debug my rtlinux module programme, and also i want to access all my
symbols in my progrramme.
advance thamnks
chandu
