The following small makefile doesn't behave as one would naively expect:
This problem is known to me for pretty very long time when I reported to Brandon D. Valentine for linux-flashplugins6 issue.. You will see in the Makefile that the PLUGINSDIR doesn't work that has like this:
=====================================
do-install:
@${MKDIR} ${PREFIX}/lib/linux-flashplugin6
.for f in ${LIBFILES}
@${INSTALL_DATA} ${WRKSRC}/${f} ${PREFIX}/lib/linux-flashplugin6
.if exists(${PLUGINSDIR})
@${LN} -sf ${PREFIX}/lib/linux-flashplugin6/${f} ${PREFIX}/${PLUGINSDIR}
.endif
.endfor
=====================================Cheers, Mezz
MANLANG?=foo "" all: .for i in ${MANLANG} .if empty(${i}) @echo foo ${i} .endif .endfor
ports-i386%make foo foo foo
I think this is because the .if evaluation is happening too early, and it's not being done after the .for loop is expanded and the i variable is set.
In order to get this to work I seem to have to do the following:
MANLANG?=foo "" .for i in ${MANLANG} j= ${i} .if (${j} != "\"\"") .for l in ${j} k+= ${l} .endfor .endif .endfor all: @echo ${k}
ports-i386%make foo
If I remove the inner .for it breaks, and if I remove the j assignment it breaks. Also if I try and remove the use of k and put an echo inside the inner .for (with the all: preceding the whole loop) it breaks.
This is extremely nasty.
Am I missing an easier way to do this?
