ld failing to find wxWidgets

I'm trying to make the minimal sample for wxWidgets. I'm getting the following output:

$ mingw32-make -f makefile.gcc

For some reason I cannot find the wxwidgets libraries; I think I may have set some environment variable up incorrectly or perhaps I should have moved them to /mingw/lib?

Could someone help me track this down or point me in the right direction, I'd really appreciate it.

Thanks!

Did you build wxWidgets libraries as explained in the MinGW section of the documentation? It looks like the linker can't find the libraries because they are simply not there -- which would seem to indicate that you didn't build them. You need to do this first, before building the samples.

You have told gcc to link the wxWidget libraries but haven't told it where to find them.

Just add -Lc:/your_wxwidget_path to the command line options for for the linker and it should link.
