wx pdf samples not working?

I cant compile the examples from the "wx.mod\samples\pdfdocument" folder.

I get

Linking:barcodes.debug.exe
..mypath/Blitzmax/mod/wx.mod/wx.mod/wx.debug.win32.x86.a(wxglue.cpp.debug.win32.x86.o):wxglue.cpp:(.text+0x2f5): undefined reference to `_wx_wxapp_wxApp__OnInit'

Build Error: Failed to link ..mypath/Blitzmax/mod/wx.mod/samples/pdfdocument/barcodes.debug.exe
Process complete

[EDIT] : I'm using the latest download version of wxWindows, wxmax_1_00_win32_bin.rar wxMax 1.00 - src + Win32 precompiled modules, and get the same error on a wxcodegen test I just made. Other examples work ok.
