• Add host support by MinGW under Linux (recommend apt-get install gcc-mingw32 and use below command to install mingw32-zlib)

wget http://apt.arrozcru.org/mingw32-zlib/mingw32-zlib_1.2.5-1_all.deb; sudo dpkg -i mingw32-zlib_1.2.5-1_all.deb

The build environment

You can use below command from android-apps-host to compile:

compile.sh

If your app need contents from AndroidConfig.h (e.g. on linux host, adb.c need HAVE_FORKEXEC), please export ANDROID_SYS_HEADERS like compile.sh

if your app need ld to some .a files (e.g. on linux host, adb need libcutils.a, you can get the .a files from compiled Android source or modify and run host-libs/gen-libs.sh from android-apps-host), please put them to export HOST_LIBS=${PWD}/host-libs folder described in compile.sh
