Re: GMAKE 3.81 vs GMAKE 4.2

[nikhil jain]

Hi guys,

I just tried the die function inside main.c

It did not get called when I ctrl + c a running make process. Please help
here.

Also, fatal error handler in commands.C gets called multiple times. I
believe it is getting called for each parallel make process the parent has
invoked.

Helpless now, need to find answer to below questions -

1) why the die() function is not getting called after a ctrl+c ?
2) why I am not able to printf anything in fatal error handler in
commands.c ? I do printf but it doesn’t print on the screen. The stdout is
gone?
I tried running some command using system call and it ran means the control
is definitely doing inside fatal error handler.
3) I basically want to know a way in which I should be able to execute a
piece of code when main exits. Where should I put it?


Just a note - the makefiles are not normal. They are trapping sigint using
TRAP command in gnumakefile.

Please help guys.

Thanks in advance
Nikhil
