| I would like to use gcc and g++ for development on SVR4 platforms.
| Unfortunately, this may not be possible, since g++ doesn't emit DWARF
| symbols for debugging.
| 
| So, I would like to know what my options are for getting g++ to emit
| DWARF.  Here's what I've thought of off the top of my head:
| 
|     (1) Modify g++ to do The Right Thing.
| 
|     (2) Pay someone to modify g++ to do The Right Thing.
| 
|     (3) Get g++ to emit a different kind of debugging info on SVR4 --
|         STABS comes to mind.
| 
| Item (1) is listed only to show that I did think of it.  It is out of
| the question because I lack the time (and also most likely the
| expertise) for such an endeavor.
| 
| Item (2) is possible, but unfortuntely not very feasible at this time
| due to budget constraints.
| 
| So I'm left with (3).  Someone did it for Solaris; Can it be done for
| other SVR4 platforms?
| 
| Any comments welcome.

It should be fairly simple:

   1)	Modify your config/i386/sysv4.h to include the following
	lines:

	#define PREFERRED_DEBUGGING_TYPE DBX_DEBUG

	#ifndef DBX_DEBUGGING_INFO
	#define DBX_DEBUGGING_INFO	/* enable dbx debugging */
	#endif

   2)	Build and install the current version (2.2) of the gnu
	assembler, and the binary utilities (2.3).

   3)	Configure gcc with the -use-gnu-as and -use-gnu-ld switches.

Note in doing this, you lose shared libraries, since neither gas nor
gld currently support ELF shared libs.  If you want to produce dwarf
debugging, use -gdwarf instead of -g.
