Hi Alejandro, > I didn't use them simultaneously. There are 3 scenarios: > 1. No options: builds. That is the same as -O0 "do not optimize". > 2. -O1/-O2/-O3: runs out of memory. Did you try -O1 (or -O2 or -O3) and -fno-* disable all the optimizations that can be disabled? Note that most optimizations enabled by -O1 (and greater) do not have -f* toggles. > 3. -f* (corresponding to when enabling -O2 as manpage says, but NOT -O2): builds, but the final program runs at the same speed. That is the same as -O0 "do not optimize". The -f* are ignored. > Do you want the preprocessed source, and the exact -f* options? No. > I was initially looking for using -O2 with necessary -f-no-* to avoid running out of memory. That is the approach I recommend. HTH, --Eljay
