Sorry about the multiple emails. I managed to get past the library not found
error - it was a matter of nomenclature.
However, now I am trying to call a function in the library through an included
header file (which is part of the library) and it fails (undefined reference).
My header file: init.h
#define BLAH 10
int abcd = 5;
int hello();
Code in my init.c
int hello(){
printf("Hello");
}
My C++ code:
extern "C"{
#include <l4/libscc-sec/init.h>
}
int main(){
printf("Vars from lib %x, %x", BLAH. abcd)
hello();
}
The program fails to compile with the calls to the function hello. If I remove
hello, it compiles.
I made sure that I am indeed using the extern "C" directive. I also tried
putting the function declaration in here instead of the header file itself but
it does not help.
Thanks,
ramya

Subject: Adding a custom library to l4/pkg/bootstrap
Hi all,
I have managed to compile a custom C library (libscc-sec) as part of the l4
packages. Now I would like to use it in the bootstrap package (make a call to a
function in the library). I did the following:
a. Added the library as a requirement in pkg/bootstrap/Control
requires: drivers_uart drivers_of libc l4util cxx_io libscc-sec
b. Modified the pkg/bootstrap/server/src/Make.rules so that it also looks for
libscc-sec by:
L4_LIBS = -static -nostdlib $(DRV_LIBS) -lcxx_base -lcxx_io
-llibscc-sec
But on compiling, I get an error that says that -llibscc-sec not found
The package is getting compiled and I can see the library libscc-sec.a in the
build folder. What am I missing?
Thanks,
ramya
