Hi John,
Good to hear that has been solved :). Under Cygwin all these DLLs are initially created in the dll subdirectory under the build directory but with "make install" they will go into the bin directory ofyour Cygwin installation and then adjusting the path is no longer required. That is also the way forward for installing your applications on other machines.
Regards,
Arjen

Hi Chris,
Thanks for that tip! It immediately resolved the problem. Things work beautifully now.
Thanks again. John

Are the .dll files in the PATH?

Hi Arjen,
I have still had no success in getting my application to work linked to plplot-5.10.0 under Cygwin. Here is what I am seeing. Things apparently compile and link okay:
$ make sphplt
gfortran -fdefault-real-8 -O3 -fdefault-real-8 -O3 -I/usr/local/plplot/include -L/usr/local/plplot/lib -o sphplt sphplt.o graphx.o \
-lplplotd -lplplotf95d -lplplotf95cd
But then when I execute I get the following error:
$ sphplt
/home/johnrb/terra0314/sphplt.exe: error while loading shared libraries: cygplplotf95d-11.dll: cannot open shared object file: No such file or directory
Might you have any idea what I am doing wrong here? Thanks for any help you can provide.

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.
