[Rd] rgl: bogus configure[.ac] (PR#14183)

2010-01-12 Thread jel+r

The configure.ac is bogus, since it does not include additional library pathes
at the right place and thus fails. E.g.:

$R_HOME/bin/R CMD INSTALL -l $PROTO/R/library \
--configure-args='--with-gl-includes=/usr/X11/include/NVIDIA
--with-gl-libs=/usr/X11/lib/NVIDIA/amd64' $TMPBUILD

And thus configure tries: cc ... -lGL -L/usr/X11/lib/NVIDIA/amd64
which obviously fails: the path needs to be placed before -l...
So the correct way is to add the path to LD_FLAGS instead of LIBS.

To get the path at the correct place into the to PKG_LIBS limitted Makevars,
one
needs to add the path, when the LIB expansion has been done. Suggested patch:
