mkoctfile and compiler options

[john.2.tomlinson]

All

Is there anyway I can stop mkoctfile from using the -O2 optimiser flag?

I have tried re-building octave without the flag set in the CFLAGS environment variable. I have tried setting CFLAGS. Still mkoctfile insists on inserting the -O2 flag

octave:3> mkoctfile -p CFLAGS
-ggdb
octave:4> mkoctfile -v fred.cpp
g++ -c -fPIC -I/usr/local/include/octave-3.0.2 -I/usr/local/include/octave-3.0.2/octave -I/usr/local/include -mieee-fp -g -O2 fred.cpp -o fred.o

g++ -shared -Wl,-Bsymbolic -o fred.oct fred.o -L/usr/local/lib/octave-3.0.2 -L/usr/local/lib -loctinterp -loctave -lcruft -lfftw3 -lreadline -lncurses -ldl -lz -lm -L/usr/lib/gcc-lib/i586-suse-linux/3.3.3 -L/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../../../i586-suse-linux/lib -L/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../.. -lz -lfrtbegin -lg2c -lm
