[wxWidgets] Compiling wxWidgets for MS Windows

Posted on Dec 30, 2014

1. Get the latest source code from https://www.wxwidgets.org/downloads/ (ver 3.0.2 as of Dec 30, 2014) and unzip it somewhere.

2. Go to ./build/msw

3. Compile
– For MS Visual Studio, find a solution file for your VS version (e.g., wx_vc12.sln) and build.
– For MinGW, open a cmd window and set the bin folder of MinGW in the beginning of your PATH environment variable, like the following example.

set "PATH = C:\GNU\mingw64\bin;%path%"

Then, run the following commands, depending on the version you want to build.

@ release DLL
mkdir ..\..\lib\gcc_dll\mswu\wx
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=release SHARED=1 UNICODE=1 MSLU=0 clean
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=release SHARED=1 UNICODE=1 MSLU=0

@ debug DLL
mkdir ..\..\lib\gcc_dll\mswud\wx
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=debug SHARED=1 UNICODE=1 MSLU=0 clean
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=debug SHARED=1 UNICODE=1 MSLU=0

@ release static LIB
mkdir ..\..\lib\gcc_lib\mswu\wx
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=release SHARED=0 UNICODE=1 MSLU=0 clean
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=release SHARED=0 UNICODE=1 MSLU=0

@ debug static LIB
mkdir ..\..\lib\gcc_lib\mswud\wx
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=debug SHARED=0 UNICODE=1 MSLU=0 clean
mingw32-make -f makefile.gcc CXXFLAGS="-std=gnu++11" BUILD=debug SHARED=0 UNICODE=1 MSLU=0
