Hello folks,
I am trying to convert my (managed makefile) application into a multi-segment
one. In particular, I would like to put in a separate code segment one function
and all functions called by it (they aren't called by anything else). So far,
I've done the following:
1) Added a Sections.def file to my project, with the following contents:
application { "AppName" CrID }
multiple code { "code1" }
(where "Appname" is the name of my application and "CrID" is its creator ID).
2) Added a Sections.h file to my project, with the following contents:
#ifndef _SECTIONS_H
#define _SECTIONS_H
#define SECTION2 __attribute__ ((section ("code1")))
#endif
3) Added a
#include "Sections.h"
line to the source file of my application (there is only one).
4) Changed the prototypes of all functions that I want to put in the second
code segment from
RetValueType functionName (blah-blah);
to
RetValueType functionName (blah-blah) SECTION2;
Unfortunately, I still cannot compile the project. :-( I get the error
/usr/m68k-palmos/bin/ld: warning: no memory region specified for section `code1'
FileName.c:LineNum: undefined reference to `__text__code1'
where "FileName.c" is the source of my application and "LineNum" is the number
of the line on which I call the main function that I want to put in a separate
segment.
Any hints what I am doing wrong?
I am assuming that if I don't add a "SECTION2" to the prototype of a function,
it will go into code 1. Do I have to create an __attribute__ for code 1 too -
and add "SECTION1" to the prototypes of all functions that have to go into the
code 1 resource? Do I have to add "SECTION2" also to the implementation of the
functions - not just to their prototypes?
At a guess, the problem occurs because I am using a managed makefile project
and originally it was created as a single-segment project. For instance, its
automatically generated makefile does not contain
MULTIPLE_CODE_SECTIONS = TRUE
Any ideas how to tell a managed makefile project that it should be a
multi-segment project? What project properties to modify?
Regards,
Vesselin
