debug build

Hey all,

I’m use DDD as my debugger, and unfortunately, I think gcc (for Appbuilder -
Phab) is compiling with optimizations even though I am compiling in debug
mode. In the make screen, I can clearly see the “-O” option meaning
optimizations off, but this has no effect. Lines such as the following are
simply deleted.

void foo()
{
unsigned long x;

PtGetResource(…&x)
x = x & Pt_SET;
return;
}

In this case, the line with Pt_SET is deleted. I know the line should be
deleted with optimizations on. Anyone have any ideas?

Oops, time for a manual check :slight_smile:.

-O does not mean “optimizations off”.

-O means some, but not all, optimizations on. -O2 means more
optimizations on. -O3 means even more optimizations on. Etc.

If you don’t want any optimizations, you should not have any -O flag.
That means optimizations off :slight_smile:.


HTH!

or you can pass -O0
