Re: [Plplot-general] plwidth fails to link under Cygwin against plplot5.9.10 libraries

[John B. <jrb...@co...>]

Hi Alan,

Thanks for your quick response!  I had earlier tried the 5.10.0 
release with a version of my Fortran code where I had inserted 'use 
plplot' everywhere a plplot routine is called, but had encountered 
problems I could not resolve.  That is why I went back to the 5.9.10 
release.  When I commented out all the calls to plwidth at least the 
code compiled and could be executed.  Here are the sorts of errors I 
get with the 5.10.0 release:

$ make sphplt
gfortran -fdefault-real-8 -O3 -Iinclude -Llib  -c -o graphx.o graphx.f
graphx.f:106.72:

       call plline(n101,xx,yy)
                                                                         1
Error: There is no specific subroutine for the generic 'plline' at (1)
graphx.f:2079.72:

          call plfill(4,x,y)
                                                                         1
Error: There is no specific subroutine for the generic 'plfill' at (1)
graphx.f:172.72:

                   call plfill3(3,xr(1,1),xr(1,2),xr(1,3))
                                                                         1
Error: There is no specific subroutine for the generic 'plfill3' at (1)

I copied the lib and include directories created in 
plplot-5.10.0/build_dir to the filespace where I am seeking to 
compile.  I also copied all the files in the directory bindings/f95 
to the local filespace.  I suspect I am still missing some crucial 
files.  Can you identify what is wrong here?

Thanks so much for your assistance!
John
