Hey Jan,
Sorry for underspecifying it. Here are the details.
I have a library called scc-sec under the l4/pkg directory. It has one file:
a. init.c that contains
void hello(){
printf("hello");
}
I compile this as a library and I can see the scc-sec.so and scc-sec.a in the
l4/build/pkg/scc-sec directory
Now in l4/pkg/bootstrap:
a. Control file
requires: (added) scc-sec
b. Make.rules:
-lscc-sec
Is "-lscc-sec" the literal content of this file? That doesn't do anything.
c. startup.cc
I declare the function as:
extern "C" {
void hello();
}
and somewhere in startup() function, I call it
hello();
On trying to compile this, I get (exact error as it is compiled)
in path_to-startup.cc: undefined reference to function "hello()"
I do not think it is the printf because it explicitly gives me an undefined
reference to hello :)
To me this looks like you don't actually link to your scc-sec library.
Does your Makefile for bootstrap include something like
REQUIRES_LIBS = scc_sec
?
Martin
