-fomit-frame-pointer + -g

-fomit-frame-pointer + -g

[Ricardo Catalinas Jimenez]

hi everybody,

my system is configures with the CHOST, CFLAGS & CXXFLAGS to use the useful
'-fomit-frame-pointer' flag. But when I want to debug one of my binaries, I
add manualy to the compilation process the '-g' flag.

My computer is an ia32 where the '-fomit-frame-pointer' is incompatible for
debuging.


I looked on the web but I didn't find if when I use both options what happend.

So when I do: gcc -o test test.c -g -fomit-frame-pointer

What happend, can I debug correctly?

If not, what I have to do? Should I disable the '-fomit-frame-pointer'
manually every time I want to debug?

Thanks in advande.

Even easier than asking others to dig into your problem, how about just
firing up a gdb yourself and have a try? You'd just see the result:-)

I have tried it. The debuging is not imposible. But I not an expert in that,
so I don't find the limitations of debuging with '-fomit-frame-poiner'. 

Further more I made sure that when I compile with both options the binary is
different when I compile only with '-g'.

Is there any function to delete lines from a text file

[Edward Parrilla]

Hi there,
I know that fputs(), or fgets() can store or get a line from a file, is
there a way to delete a line from a text file?
Thanks in advance
Edward

No.

The only way to do that is to copy the whole file and omitting the line
you want to omit (using the "f" functions). Alternatively, you'd use the
"normal" functions and only copy the part after the line to be deleted
some bytes towards the front...
