I forgot to mention you'd have to change over to C++ by renaming the source file
with the extension .cpp instead of .c so the compiler switches modes.

^- that's still the problem with <windows.h> having the same function name as one
contained in jnior_300.h. Just like the error says. What you could do is to not
#include <windows.h> at all. Tcl extensions can build without it as long as they
don't use any of the services. To be honest, you should contact the API authors
and ask them how to handle their error.

Creating library jnior310tcl2.lib and object jnior310tcl2.exp
jnior310tcl2.obj : error LNK2019: unresolved external symbol

jnior310tcl2.dll : fatal error LNK1120: 2 unresolved externals

That part has me perplexed. jnior300.lib is included in the link, yet the linker
does resolve any function contained in it. I think you'd better ask the authors
about that. You can use the lib.exe tool to query what it contains. I'm assuming
it is an import library. If it's an import library made be Borland C++ builder,
it won't work with the MS toolchain. Even if its a static library, it should
resolve something.

IT COMPILE!!!!!

I use namespace as you suggested and renamed the file to .cpp Got
zero warnings and error messages!!!

When I load it, I get the following error:
tclsh> load jnior310tcl2.dll
couldn't load library "jnior310tcl.dll": this library or a dependent
library could not be found in library path

Which appears to be an error because it depending on the SDK dll
(jnior300.dll). I append the path to auto_path and I still get the
error message. Looked through the groups, and there are two
possibilities:
1) My paths are wrong
2) The DLL has an internal error

BTW: I also tried to copy the jnior300.dll into "C:\Program Files\Tcl
\lib" and "C:\Program Files\Tcl\bin" and neither worked. I also
copied the file to "C:\WINDOWS\system" and "C:\WINDOWS\system32" and
nothing.

I remember way back when (1997) on windows NT, I was able to look at
DLL properties to see dependencies and where the dependencies should
exist. Just can remember the name of that tool.

Will investigate further!!

-JC

I executed "Depends" from the MS Platform SDK Tools to see analyze the
jnior310tcl2.dll. In there, i have two yellow question marks, one for
jnior300.dll and the other for msvcr80.dll. When I select either of
these dlls, I able to see the function name, but if i right click on
them to see the properties, I get an error message that it can not
find it.
