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
Makefile
s. 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
