Because you need to define empty STRIP, too.

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,

No.
You are assuming every program's Makefile uses WITH_DEBUG that way! The base
system doesn't for one. And neither do all ports. To look for yourself, use
the following command;
find /usr/ports/ -type f -name Makefile -exec grep -H DEBUG {} \;
While a lot use WITH_DEBUG, not all ports do, and some use other options, like
NODEBUG or DEBUGFLAGS, or DEBUGGING.
You'd have to look into the programs in question to see how to enable
debugging for those.

You'd lose `-O2' compiler-specific optimization. If you want to retain
it use DEBUG_FLAGS, e.g.
DEBUG_FLAGS = -ggdb
CFLAGS += ${DEBUG_FLAGS}
Ports that build using bsdmake don't really need the second line as well
as buildworld.

Besides symbols some ports enable compile-time debugging and disable
optimization using WITH_DEBUG ifdef that may impact performance.

Setting Debug flag in /etc/make.conf
I have been having problems with several different programs lately. Would there be any serious drawback to simply setting: "WITH_DEBUG= " in the /etc/make.conf file to force everything I build/rebuild to be built with debug symbols? I am assuming that I can simply place that flag in the make.conf file. Do I have to also give it a value; i.e "=1" or "=yes" also? -- Jerry ✌ freebsd.u...@seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.
