I think you are missing some Windows libraries.

Here is the command line for the wxWidgets minimal sample

l:\Dev\Desktop\Lib\wxWidgets-GIT\samples\minimal>mingw32-make -f makefile.gcc
g++ -o gcc_mswud\minimal.exe gcc_mswud\minimal_sample_rc.o gcc_mswud\minimal_minimal.o -g -mthreads -L.\..\..\lib\gcc_lib -Wl,--subsystem,windows -mwindows -lwxmsw31ud_core -lwxbase31ud -lwxtiffd -lwxjpegd -lwxpngd -lwxzlibd -lwxregexud -lwxexpatd -lkernel32 -luser32 -lgdi32 -lcomdlg32 -lwinspool -lwinmm -lshell32 -lshlwapi -lcomctl32 -lole32 -loleaut32 -luuid -lrpcrt4 -ladvapi32 -lversion -lwsock32 -lwininet -loleacc -luxthem

I would make sure that all those libraries are in the project's linker settings.

Hi,
In addition:

- make sure they are in the proper order
- I'd also add "_UNICODE" to the defined symbols list.

Thank you.

Compiled fine. No errors.

Thank you *SO* much!!!!
