Unknown symbol _exit when compiling VMware vmmon.o module

Unknown symbol _exit when compiling VMware vmmon.o module

[Felipe Alfaro Solana]

Hi!

After installing VMware Workstation 4.5.0-7174 and running
vmware-config.pl, I get the following error when trying to insert
vmmon.ko into the kernel:

vmmon: Unknown symbol _exit

What can I use instead of _exit(code) inside a module?
Thanks!

panic()? (Where would the kernel _exit() *TO*?)

I think you misbuilt the kernel module...

If I do interpret this right please read:

I've seen it too.  I just removed that call from the source and
rebuilt.  It's not supposed to ever get there anyway.  I still don't
understand what it was doing there in the first place.  Oddly, it
compiled with kernel 2.6.2, but not with some later updates.

No, I don't think so... look at this code:

#ifdef MODULE_X86_64
	exit(1);
#else
	_exit(1);
#endif
	for (;;);	/* To suppress warning. */

This is a snippet from driver.c.

Bah! I've simply removed the #ifdef...#endif code and it seems to work,
but I was really curious why VMware was using _exit() for i386 and
exit() for x86_64.

Yeah! I experienced the same with -mm kernels... It seems the changes
that motivated that have been integrated in mainline now. For now, I've
removed any reference to _exit from the module sources.
