Need help compiling Reaction examples with GCC

[jahc]

I'm trying to compile the Reaction examples that were included in the 3.9 NDK. I'm using GCC 2.95.3.. these are the errors I get on the listbrowser example:

5.dh2:NDK_3.9/Examples/Reaction/ListBrowser> g++ test.cpp

.. What do I need to do to get this to work? I'm a bit of a programming newbie, so please excuse my ignorance.

Did you use fd2pragma to create correct headers, and include protos?

Yes.

-Edit- the example compiles perfectly in stormc 3.0 , however I want to use GCC so that my stuff will recompile easily for OS 4.0.

[jahc]

/gg/m68k-amigaos/bin/ld: cannot open -lauto: No such file or directory

doesnt seem to work.. g++ -lauto test.cpp or g++ test.cpp -lauto  .. or gcc with those combinations.

If there are no solutions to this problem by the time I wake up tommorow morning, I will just use stormc. I'll just have to worry about porting to OS 4.0 when their dev kit comes out. It should be fully setup with reaction etc. I'm not being negative, I just want to start experimenting and achieving.

Thanks for your help so far guys.

-Edit- I couldnt wait till morning, I'm using stormc!! thanks anyway people.
