Compiling a Simple Plug-in.

Can anyone show me how to compile the simple Plug-in1 "hello' message on GIMP. The simple plugin for gimp is available at this link :http://developer.gimp.org/writing-a-plug-in/1/index.html. I have included one header file called libgimp.h which is similar to #include from the developers website.
I am using devcpp-4.9.9.2 with mingw compiler for windows. I have 41 error when trying to compile the Simple Plug-in: Compiler: Default compiler
Executing gcc.exe...
gcc.exe "D:\New Folder\hello.c" -o "D:\New Folder\hello.exe" -I"D:\Dev-Cpp\include" -L"D:\Dev-Cpp\lib" In file included from D:\New Folder\hello.c:2:

I don't see any complete source code on that page, unfortunately. What did you do, paste together the code snippets on the page?

So you say, but then the error messages you include below talk about gimp.h?

Hmm, actually using a folder called "New Folder" does not seem like a terribly bright idea. You are supposed to rename folders you create to some meaningful name. I would also recommend not using spaces in folder names, it can cause various problems sooner or later.

> D:\New Folder\/gimp.h:10: error: syntax error before '*' token

Is this gimp.h something you created yourself, or where did you get it from? And why is it in "New Folder"? If it is the standard gimp.h from a GIMP distribution, it should be in a subfolder include\gimp-2.0\libgimp of where you installed the GIMP developer files [1]. Anyway, the normal gimp.h has about twenty lines of comments at the beginning, so how can line 10 have a syntax error?

[1] There doesn't seem to be any GIMP development package for Win32 at the gimp-win.sf.net site.

There is one at http://www.gimp.org/win32/gimp-dev-2.2.7.zip . Maybe it should be advertised somewhere, although I initially intended it to be just temporary until gimp-win.sf.net would offer also a developer package. If you haven't already gathered the same headers and import libraries from somewhere else, you probably want to download that and point your compiler to use headers and (import) libraries from there.
