i-g-t + GDB

i-g-t + GDB

[Michael H Nguyen]

Hi,

I am trying to step through i-g-t & libdrm source w/ GDB but single 
stepping seems erratic so I am guessing the build is optimized. Is 
changing "CFLAGS = -g -O2" to "CFLAGS = -g -O0" the right thing to do? 
If so, how can I do that globally one time versus touching every 
Makefile inside the igt and libdrm projects? Maybe pass an additional 
parameter to autogen.sh, I'm not sure ?

Thanks,
Mike

Figured it out. For anyone interested...

$ ./autogen.sh --prefix=<my prefix> CFLAGS="-g -O0"

CFLAGS gets passed to ./configure which generates the make files w/ 
"CFLAGS = -g -O0"
