If you add this to the Makefile in every subdirectory (this is for
netgraph, for each directory please replace the string netgraph
with the name of the current directory):
.if ${MACHINE_ARCH} == "i386"
# Things that don't compile on alpha or are aout specific:
SUBDIR+= bluetooth
.endif
+CURDIR:=${.CURDIR:C/^.*\/modules\///}
+.for d in ${SUBDIR}
+.if ${WITHOUT_MODULES:Mnetgraph/${d}}!=""
+SUBDIR:= ${SUBDIR:N${d}}
+.endif
+.endfor
.include <bsd.subdir.mk>
you can do:
WITHOUT_MODULES= netgraph/one2many syscons/fire
and then the modules netgraph/one2man and syscons/fire are ignored,
while the rest is happily made.
