WITH_DEBUG has special meaning in the ports infrastructure, and as long
as a specific port uses CFLAGS during compilation, it will be compiled
with debugging symbols when WITH_DEBUG is enabled. Some ports also
check the value of WITH_DEBUG within their own Makefile in order to set
port-specific debug build options.
See this excerpt from /usr/ports/Mk/bsd.port.mk:
# WITH_DEBUG - If set, debugging flags are added to CFLAGS and the
# binaries don't get stripped by INSTALL_PROGRAM.
# Besides, individual ports might add their specific
# to produce binaries for debugging purposes.
# You can override the debug flags that are passed to
# the compiler by setting DEBUG_FLAGS. It is set to
# "-g" at default.
Just put the following in /etc/make.conf and then recompile the ports
you want to include debug symbols:
WITH_DEBUG= yes
Hope that helps,
Greg
