Requirements

• MSVC toolchain
• Cygwin

Note: When installing Cygwin and selecting packages, make sure you search for and select 'make', 'dos2unix' and 'binutils'.

How to build

• set PATH=%PATH%;C:\Cygwin\bin
• dos2unix -f configure or other file

Example

c:\cygwin64\bin\bash.exe configure -prefix=/cygdrive/d/workdir/wxProject/mEditor/3rdlib/myinstall1 -enable-static -disable-shared make install
