The linker can't find the libwxmswd_core.a file.
It should exist in the $(#wx)\lib\gcc_dll if you have compiled wxWidgets as non-monolithic debug shared ansi version or in $(#wx)\lib\gcc_lib if you have compiled it as non-monolithic debug static ansi.
Be sure to have the library filename matched your wx configuration and add the directory to Search directories->Linker.

i found only libwxmsw28u_core.a & libwxmsw28ud_core.a

is that means i need recompile with a non-unicode version?

[raph]

That means that wxWidgets is compiled as:
non-monolithic, unicode, normal and debug
Simply select that options if you are creating a new project with wxwidgets wizard or change the libraries to link in the build options manually.

is that means i need recompile with a non-unicode version?

No, using unicode is recommended unless you want your application to run under win95/98/me.
