I would like to use the General Polygon Clipper (GPC) thur IDL.
This is a software package written in C that is available from
Manchester that clips polygons.
Has anyone implement this in IDL, already?
I assume MAKE_DLL is the way to go.

Ok, typically when using visual studio from the command line you need
to execute a batch file so set the paths correctly. On my machine this
is vsvars32.bat. It it siemwhere in the visual studio tree. I copied
it to c:\windows so that it is always found. Then try the examples
again, and do not attempt to compile gpc until the examples work. The
next question I have is whether you wrote the proper wrapper routines
to interface from IDL to gpc?

Nope!
I have been working with the ITTVIS example routine SIMPLE_VARS.pro
Common errors are undefine reference, unrecoginize commands (CL),
missing libraries (mspdb100.dll), and cannot find <stdio.h>.

Were you able to successfully compile any of the small example
programs in the IDL external directory?

Still working on it, but starting to lose steam.
Tried to use gcc from CYGWIN to compile C source code. Failed. Reports
from
from tech support and other IDL users, avoid doing this.
Installed Visual C++ (express) as recommended by tech support and
other IDL
users. Used the Visual Command Prompt, but still unable to make a 32-
bit
DLL without getting some kind of warning or error.
Installed MinGW as suggested by tech support and other IDL users. From
their
experience, they have more success with compiling 3rd party packages
with this
package. I was able to creating a 32-bit DLL with ggc in the MinGW
shell. Used
-shared option to gcc to create a DLL. For example :
gcc -Wall -shared gpc.c -o gpc.dll
Despite the success of creating a DLL, the 32-bit IDL 6.4 crashes when
CALL_EXTERNAL
is used to access this sharable library. For sure, I didn't use the
compiler properly
to create a sharable DLL.
Found a sharable DLL for the General Polygon Clipper at Mathworks
(circa 2005). Needs
a MatLab library to work. I didn't purse this much further, as I no
long have MatLab
on my desktop.
New Life! Michael Galloy announced his book is available - Modern IDL.
There is a whole
chapter about this External Development. So, there is lots of new
ideas to try. Even
a Python example. GPC has a Python wrapper.

Becoming a little wiser.
Visual Studio Command Prompt is looking for "vcvarsall.bat"
I did install MinGW. From the MinGW shell prompt I was able to make a
DLL -
gcc -Wall -shared gpc.c -o gpc.dll
However, this is a 32-bit DLL. The IDL 64-bit version using
CALL_EXTERNAL doesn't like the DLL.
Although, the IDL 32-bit version does like the DLL, but IDL promptly
crashes.
Progress!

Make sure to launch IDL from the special command line provided by VS (or
set your path and possibly other environment variables accordingly).

Yes, apparently the ITTVIS example assumes you have Microsoft Visual
installed.
Well, I spent most of the day installing Microsoft Visual C++ 10.0 and
regist for the free version.
So far, here are the problems I am having :
cl.exe : Solution ?
mspdb100.dll pop-up : Solution ?
stdio.h 'no such file' : Solution ?
I am sure the problems are related to path, as all these file are
within the new install of MS Visual Studio 10.0.

Well this works (ITTVIS example) ...
Start up a Command Prompt ...
Drag-n-drop the vsvarall.bat from the Visual Studio C++ 10.0 VC
directory into the command prompt ...
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC
\vcvarsall.bat"
Drag-n-Drop the (IDL 6.4) idlde.exe into the same Command Prompt ...
"C:\Program Files\ITT\IDL64\bin\bin.x86\idlde.exe"
Hit return in the active command prompt and the IDL DE starts up.
Now you can running the ITTVIS CALL_EXTERNAL examples work just fine.
However, is this a viable solution?
Maybe for a quick and dirty - get-it-done - option.

Will the vsvarall.bat file work? It is in the Visual C++ 10.0
directory.
The vsvar32.bat is in the VC /bin directory.
I moved the vsvarall.bat (as well as the vsvar32.bat) to the C:
\windows
directory and the same problems persit. You move it there to be found
by what app? I assume MAKE_DLL is starting a adminstrator command
prompt.
I have yet to work on the IDL wrapper for GPC. I am still working to
get
the ITTVIS examples to work.

For Windows, what I have done (haven't done this for awhile, though) was
to just set the environment variables that vcvarsall.bat sets. I don't
remember clearly, but I think this was a bit of a hassle. But then
CALL_EXTERNAL, MAKE_DLL, etc. "just work" all the time.
