Hi Daniel,


signal.h is not a library. It is just an include files that contains some macro 
definitions.

#define eint()  __asm__ __volatile__("eint"::)

which just puts an assembly command into the code flow.

Also the interrupt functions are just defines that allow you to write

interrupt (vector) name (void)

instead of

void __attribute__((interrupt (vector))) name (void)

If you write the long forms yourself in your coude, you can do easily without 
signal.h.
But why should you? It does not add any code by itself. It just makes your code 
more readable and saves you some keystrokes.

But your error messages indicate that you didn't include it in this particular 
code file. Therefore you cannot use its 'shortcuts' such as dint() in this code 
file without an error.

Have you #include'd signal.h?

I don't see any reference to the system not being able to find that file,
only that the the dint/eint function declarations can't be found.

#include <signal.h> exists in all the files that need it, I thought thatthis library is not found because in mspgcc manual by Steve says that isnecessary not only for dint/eint but also to process interrupsfunctions, which is the case.

Hi JMGross,

I apologize for my mistake, I had not opened the file signal.h and Ithought would contain functions calls.

Anyway copying signal.h from the original directory (/usr/msp430/include) to my project directory errors are gone but theseothers who may be related to access to the library libc.a appears.


I'm trying this toolchain in Ubuntu 9.1. (Karmic Binaries by Adam Horden )
