The port should respect the CFLAGS variable.
What we mean by this is that the port should not set the value of
this variable absolutely, overriding the existing value; instead,
it should append whatever values it needs to the existing value.
This is so that build options that affect all ports can be set
globally.
If it does not, please add NO_PACKAGE=ignores
cflags to the Makefile.
An example of a Makefile respecting
the CFLAGS variable follows. Note the
+=:
CFLAGS+= -Wall -Werror
Here is an example which does not respect the
CFLAGS variable:
CFLAGS= -Wall -Werror
The CFLAGS variable is defined on
FreeBSD systems in /etc/make.conf. The
first example appends additional flags to the
CFLAGS variable, preserving any system-wide
definitions. The second example clobbers anything previously
defined.
You should remove optimization flags from the third party
Makefiles. System CFLAGS
contains system-wide optimization flags. An example from
an unmodified Makefile:
CFLAGS= -O3 -funroll-loops -DHAVE_SOUND
Using system optimization flags, the
Makefile would look similar to the
following example:
CFLAGS+= -DHAVE_SOUND
