+
+## cross-compiling W32 binaries from linux
+
+I'm using the following to cross-compile W32 binaries on my Debian/64bit system,
+using `mingw-w64`.
+
+Assuming you have unzipped a W32 package for Pd into `${WINPDPATH}`, run:
+
+    make system=Windows pdbinpath="${WINPDPATH}/bin/" pdincludepath="${WINPDPATH}/src/" CC=i686-w64-mingw32-gcc
+
+(if the project uses C++, you might also need to sed `CXX=i686-w64-mingw32-g++`)
