Can't compile wxWidgets with Mingw32

Dodle (18)
Hello, I am new to the forum, and pretty new to programming as well. I have been using wxWidgets with Python but recently wanted to learn C++. I am running Windows XP Pro.

I've installed wxWidgets and am using Mingw32 for my compiler. I'm having a lot of trouble. Here is the command I have been using to compile:
c++ sample.cpp -o sample

I get the following error:
1
2
 
wx/wx.h: No such file or directory
wx/sizer.h: No such file or directory


I tried adding WXWIN environment variable with no effect. So I started telling the compiler where wxWidgets was installed:
c++ sample.cpp -B C:/Env/wxMSW-2.8.9 -o sample

Apparently with this the compiler found wxWidgets, but is still giving me errors. Too many errors to paste in here. Here is part of what prints out:

Does anyone know what I am doing wrong?

To use a library in C++ you need at least two things and possibly a third one: the headers, the static library, and maybe a dynamic library that is only used at run time if at all.

It seems your compiler knows where the headers are, but you still need to link the static libraries. In Windows, these have .lib extension. gcc uses the -l option to link static libraries.

Okay, I'm not sure where to find the static library so I tried the following:

c++ sample.cpp -B C:/Env/wxMSW-2.8.9 -l C:/Env/wxMSW-2.8.9 -o sample

Now it doesn't give me a bunch of lines of output. It gives me the following:

1
2
 
cannot find -lC:/Env/wxMSW-2.8.9
collect2: ld returned 1 exit status


Also, is there a way to permanently add a directory to Mingw32's search path so that I don't have to type in -B every time I compile?

-l only takes a library name. To add a search path to a library, use the -L option, but keep in mind that it doesn't search recursively.

Did you think of doing a search for "*.lib"?

I'm getting a bunch of link errors like the following:

[Linker error] undefined reference to `wxFrameNameStr'


I'm using Dev-C++ with Mingw32 now.

I think I've made some progress, but can't get past the following errors. Does anybody know what is wrong?
