Subject: [Plplot-general] How Do I Link Correctly To the Libraries Under 5.10.0?

Hi Arjen and Alan,

   After achieving apparent success several days ago compiling and linking my application code under plplot-5.10.0, for some reason things ceased to work.  The make process could no longer find the required libraries.  So I went to examples/f95 and imitated (I think) the makefile I found there (Makefile.examples).  Here is the resulting makefile I am attempting to use:

F95 = /usr/bin/gfortran.exe
FFLAGS = -fdefault-real-8 -O3
PKG_CONFIG_ENV = PKG_CONFIG_PATH="/home/johnrb/plplot-5.10.0/build_dir/lib/pkgconfig"
RPATHCMD = -Wl,-rpath -Wl,/home/johnrb/plplot-5.10.0/build_dir/lib

sphplt : sphplt.o graphx.o
        $(F95) $(FFLAGS) $(RPATHCMD) -o sphplt \
        `$(PKG_CONFIG_ENV) pkg-config  --cflags --libs plplotd-f95` \
        sphplt.o graphx.o -lplplotd -lplplotf95d -lplplotf95cd

Here is what I get when I do the make:

$ make -f makesph
/usr/bin/gfortran.exe -fdefault-real-8 -O3 -Wl,-rpath -Wl,/home/johnrb/plplot-5.10.0/build_dir/lib -o sphplt \
`PKG_CONFIG_PATH="/home/johnrb/plplot-5.10.0/build_dir/lib/pkgconfig" pkg-config  --cflags --libs plplotd-f95` \
        sphplt.o graphx.o -lplplotd -lplplotf95d -lplplotf95cd
/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lplplotf95d-11.0.0
/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lplplotf95cd-11.0.0
collect2: error: ld returned 1 exit status
makesph:8: recipe for target 'sphplt' failed
make: *** [sphplt] Error 1

  Any ideas as to what I am doing wrong?  Thanks for any help you can provide.

John

P.S. Here is the pkgconfig/plplotd-f95.pc file:

libdir=/home/johnrb/plplot-5.10.0/build_dir/bin
includedir=/home/johnrb/plplot-5.10.0/build_dir/include/plplot
drvdir=/home/johnrb/plplot-5.10.0/build_dir/lib/plplot5.10.0/driversd

Name: PLplot F95
Description: Scientific plotting library (F95 bindings, double precision)
Requires: plplotd
Version: 5.10.0
Libs: -L${libdir} -lplplotf95d-11.0.0 -lplplotf95cd-11.0.0
Cflags: -I${includedir} -I/home/johnrb/plplot-5.10.0/build_dir/lib/fortran/modules/plplot

Question:  Why is libdir set to /bin and not /lib? /bin does not have libplplotf95d-11.0.0 while /lib does.
