Hello,
the following patches allow a variety of options additional
to the linker magic involved for hijacking the aplications main
function.
the original method will still continue to work, differences are
* the code dealing with retrieving the commandline arguments
is moved into libcobale/libmercury. Making the necessary per-application
code much smaller.
* the implementation was moved into a header, with several macros
controlling functionality (not everyone wants to define a main function).
The approach I use personally is to compile and link my own bootstrap code,
which is preferable in many build systems as source-files are understood while
objects files generally need some special care. (And it cant hurt if the
compiler
flags match exactly).
As example:
----- add this to your file containing main
int xenomai_init_getargv(int *argc, char *const** argv);
int main(int argc, char *const argv[])
{
#if defined(__COBALT__) || defined(__MERCURY__)
xenomai_init_getargv(&argc, &argv);
#endif
....
}
----- create another file, lets call it mybootstrap.c
#define _XENOMAI_BOOTSTRAP_GLIBC_CONSTRUCTORS
#include <xenomai/bootstrap-template.h>
