The port should respect both CC
and CXX
variables. What we mean by this
is that the port should not set the values of these variables
absolutely, overriding existing values; instead, it should append
whatever values it needs to the existing values. This is so that
build options that affect all ports can be set globally.
If the port does not respect these variables,
please add NO_PACKAGE=ignores either cc or
cxx
to the Makefile
.
An example of a Makefile
respecting
both CC
and CXX
variables follows. Note the ?=
:
CC?= gcc
CXX?= g++
Here is an example which respects neither
CC
nor CXX
variables:
CC= gcc
CXX= g++
Both CC
and CXX
variables can be defined on FreeBSD systems in
/etc/make.conf
. The first example
defines a value if it was not previously set in
/etc/make.conf
, preserving any
system-wide definitions. The second example clobbers
anything previously defined.
