This is my first time using wxwidgets, and encountered some error like some functions haven't defined:
wxEntry, wxAppConsoleBase, ZN9wxtestApp6OnInitEv', and so on.


C++
D:/MyApps/digital_drawing/wxtest/wxtest/wxtestApp.cpp:17: undefined reference to `wxEntry(HINSTANCE__*, HINSTANCE__*, char*, int)'obj\Debug\wxtestApp.o: In function `Z11wxCreateAppv':D:/MyApps/digital_drawing/wxtest/wxtest/wxtestApp.cpp:17: undefined reference to `wxAppConsoleBase::CheckBuildOptions(char const*, char const*)'obj\Debug\wxtestApp.o: In function `ZN9wxtestApp6OnInitEv':D:/MyApps/digital_drawing/wxtest/wxtest/wxtestApp.cpp:23: undefined reference to `wxInitAllImageHandlers()'


Compile and link command:
C++
mingw32-g++.exe -LD:\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll  -o bin\Debug\wxtest.exe obj\Debug\wxtestApp.o obj\Debug\wxtestMain.o  obj\Debug\resource.res  -mthreads  ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxbase30ud.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxbase30ud_net.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxbase30ud_xml.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_adv.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_aui.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_core.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_gl.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_html.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_media.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_propgrid.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_ribbon.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_richtext.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_stc.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_webview.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxmsw30ud_xrc.a ..\..\..\..\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll\libwxregexud.a  -mwindows 



The command of compiling wxwidgets is as follows, and no error:
mingw32-make -f makefile.gcc BUILD=release SHARED=1 MONOLITHIC=0 UNICODE=1
mingw32-make -f makefile.gcc BUILD=debug SHARED=1 MONOLITHIC=0 UNICODE=1

You are missing an option to name the library file(s) that contain these references. In most cases it would be something like
mingw32-g++.exe -LD:\Dev\CodeBlocks\wxWidgets-3.0.0\lib\gcc_dll  -o bin\Debug\wxtest.exe obj\Debug\wxtestApp.o obj\Debug\wxtestMain.o  obj\Debug\resource.res  -mthreads  -lLIBRARYNAMEGOESHERE
