+# MXE cross build
+
+Scripts to cross build a windows QGIS binary from Linux using MXE:
+(M cross environment) http://mxe.cc/
+
+The product is a zip file that contains a Windows build of QGIS,
+ready to be unzipped on a Windows machine, it does not require
+installation, just run the `qgis` binary.
+
+Unfortunately it has some...
+
+## Limitations
+
+- No Python support
+- No OpenCL support
+- No support for the new native Windows overrides (notifications etc.)
+
+## The easy way (requires docker)
+
+From the main directory of QGIS repo issue the following command:
+
+```
+ms-windows/mxe/build.sh
+```
+
+## The hard way
+
+Follow the instructions on the website to prepare the mxe environment, you
+will need to build all required dependencies for QGIS (or see `mxe.Dockerfile` to get an idea).
+
+The following command will select the posix threads enabled target and install
+the dependencies required by QGIS:
+
+```
+make MXE_TARGETS=i686-w64-mingw32.shared.posix -j 16 \
+    qca \
+    qtlocation  \
+    qscintilla2  \
+    qwt  \
+    gdal  \
+    qtkeychain  \
+    qtserialport  \
+    qtwebkit \
+    qtwinextras \
+    libzip \
+    gsl \
+    libspatialindex
+```
+
+When done, you can check and edit the `build-mxe.sh` script and set the `MXE` path to your mxe installation directory, `MXE` can also be passed as an environment variable.
