6.3 Building mechanisms

6.3.1 make, gmake, and imake

If your port uses GNU make, set USE_GMAKE=yes.

Table 6-1. Variables for ports related to gmake

Variable Means
USE_GMAKE The port requires gmake to build.
GMAKE The full path for gmake if it is not in the PATH.

If your port is an X application that creates Makefile files from Imakefile files using imake, then set USE_IMAKE=yes. This will cause the configure stage to automatically do an xmkmf -a. If the -a flag is a problem for your port, set XMKMF=xmkmf. If the port uses imake but does not understand the install.man target, NO_INSTALL_MANPAGES=yes should be set.

If your port's source Makefile has something else than all as the main build target, set ALL_TARGET accordingly. Same goes for install and INSTALL_TARGET.

6.3.2 configure script

If your port uses the configure script to generate Makefile files from Makefile.in files, set GNU_CONFIGURE=yes. If you want to give extra arguments to the configure script (the default argument is --prefix=${PREFIX} ${CONFIGURE_TARGET}), set those extra arguments in CONFIGURE_ARGS. Extra environment variables can be passed using CONFIGURE_ENV variable.

If your package uses GNU configure, and the resulting executable file has a ``strange'' name like i386-portbld-freebsd4.7-appname, you will need to additionally override the CONFIGURE_TARGET variable to specify the target in the way required by scripts generated by recent versions of autoconf. Add the following line immediately after the GNU_CONFIGURE=yes line in your Makefile:

CONFIGURE_TARGET=--build=${MACHINE_ARCH}-portbld-freebsd${OSREL}

Table 6-2. Variables for ports that use configure

Variable Means
GNU_CONFIGURE The port uses configure script to prepare build.
HAS_CONFIGURE Same as GNU_CONFIGURE, except default configure target is not added to CONFIGURE_ARGS.
CONFIGURE_ARGS Additional arguments passed to configure script.
CONFIGURE_ENV Additional environment variables to be set for configure script run.
CONFIGURE_TARGET Override default configure target. Default value is ${MACHINE_ARCH}-portbld-freebsd${OSREL}.
