[Plplot-general] problems with using Dll in VC++.net

[Ruwei L. <rw...@ph...>]

Hi, all

     I'm trying to use plplot library for a project. It works fine with 
the static library , but it fails to
link when I using the dynamic library. I got the following error message:

         ------ Build started: Project: Tplot, Configuration: Debug 
Win32 ------

    Linking...
    LINK : error LNK2020: unresolved token (0A0000B3) plD_dispatch_init_null

    LINK : fatal error LNK1120: 11 unresolved externals

    Tplot - 12 error(s), 0 warning(s)

     I did put the "plplotd.lib", "plplotd.def", "plplotd.exp" and 
"plplotd.dll" to the project directory, link
to "plplotd.lib", and also defined "__PLDLL_H__", is there anything I'm 
still missing?

   Any help or hint will be greatly appreciated.

   Thanks

Have you looked at the makefile for the examples with the DLL in 
sys\msdev\win32\dexamples?
These compile and link allright, so I would suggest you mimick the 
compile and link options
from these examples.

If this does not work, can you send me the source code and the 
makefile/project file, so that I
can try and reproduce this on my machine? (I maintain the win32 device 
and the MSVC
build system)

Arjen

Hi, Arjen

    Thanks for replying.
    Actually, examples with DLL won't compile on my computer. I got the 
following error messages when I tried to
make:

Hi, Arjen,

    I was about to send you the source code and project file when I 
found that my project was using
C++ binding, and I tried to link it to the original plplotd.dll and a 
new "plstream.dll" which I created using
the source code (with minor change) to support C++ binding. So those 
error messages may not due to
plplotd.dll. It maybe caused by my "plstream.dll".  Is it the right way 
to create a c++ binding dll for plplot
just using the "plstream.cc" and "plstream.h"(change the declaration of  
"class plstream" to "class __declspec(dllexport) plstream")
and link the project to "plplotd.dll"?  Thanks a lot!

     I'm really really sorry for my mistake.  I got so dippy with adding 
on C++ binding, GD lib and/or freetype
to the Plplot library.

     Regards,
     Ruwei

Hi Ruwei,

no need to apologise - building programs is a hazardous and complicated 
task. All the various
options for using libraries do not help making it easier.

Right now I do not have any experience using the C++ bindings under MSVC 
(more
precisely the sys/win32/msdev platform), as I do not program in C++ 
myself. It may be
worth looking at, but that is a task for the hopefully near future.

I intended to get freetype and GD working correctly for this release, 
but there are a
few wrinkles to iron out first.

Regards,

Arjen
