How to compile

Inside your MSYS & MinGW32 environment jump into the x.yy_My_PuTTY\windows directory then run the command:

make -f MAKEFILE.MINGW putty.exe

How to install the MSYS/MinGW32 environment

Simple guide to setup the compile environment:

  • Download the mingw-builds-install.exe from
  • Execute the installer and select the GUI.
  • After installing it, only the "packager manager" it's in fact installed, so execute $MinGW\libexec\mingw-get\guimain.exe and select in the Basic Setup the packages: "mingwg-developer-tools", "mingw32-base", "mingw32-gcc-g++" and "msys-base".
  • When all is installed, to open the SHELL execute $MinGW\msys\1.0\msys.bat. Then from from this shell you can compile. Example: cd $KiTTY_DIR/0.74_My_PuTTY/windows and make -f MAKEFILE.MINGW 9bis.
