There is the following instructions in the quake manual:
"1. Download and install Boost: http://www.boost.org
2. Open src/Makefile and update CFLAGS to include Boost. E.g. if you used MacPorts, it may be:
CFLAGS=-O3 -fopenmp -I/opt/local/include -I."
My OS is Ubuntu. I have installed the boost libraries, however I do not know what to put in the variable CFLAGS in the Makefile in order to compile quake properly.
Do you have a hint?
