![]() make-standalone-toolchain.shj -arch=arm -platform=android-21 -install-dir= -toolchain=arm-linux-androideabi-4. There should be files like '/path-to-toolchain-dir/bin/arm-eabi-gcc' in your toolchain directory.Īnyway, this will tell the Makefile to use your toolchain's binaries in order to compile the C/C++ native code and create the compatible executables for your target machine.įor example, this is the commands I used to create a stand alone tool chain for a certaion Android device. Something like: CROSS_COMPILE = /path-to-toolchain-dir/bin/arm-eabi. You need to put in your Makefile the path to the toolchain directory and add the architecture suffix for the binaries inside (for example 'arm-eabi-'). The output of the script will be a directory that you can use as a toolchain in order to cross compile native C/C++ code to run on Android devices. ![]() You need to download NDK and then run the script 'make-standalone-toolchain.sh' with a few parameters (as said in the link above) that will determine the API levels of your apps, the architecture of the device etc. I have used it several times for different devices and platform. prebuilt binaries.all into a temporary folder then a copying from Tmp dir to installĭir creating a tar ie a package file to add the tmpdir wanted to know what exactly is happening here or a link or suggestion where to look.but ofcourse dont want to read very elaborate manuals.įirst of all, the best guide for stand alone toolchains in Android is here. SRC_SYSROOT="$NDK_DIR/platforms/$PLATFORM arch-$ARCH" Copying sysroot headers and libraries. to run configure and make scripts." -toolchain arch ndk-dir package-dir system platform variables are set Compute source sysroot The result is something that can more easily be used as a standalone cross-compiler, e.g. ""Generate a customized Android toolchain installation that includes a working sysroot. ![]() I was going through this script to understand what this is doing. Its enough to indicate os is Android and. Hmm, I was compiling for android and one process was running a script called make-standalone-toolchain.sh a standalone toolchain is created. Using CMake build-in Android NDK support For this approach, you dont need to specify CMake toolchain file at all. Also they use now clang as compiler and the libc++ as standard. Why the term "standalone"? This probably will be different that the regular toolchain in the sense that the R T will need to be configured and made ready for android use withe sysroot and libc header paths given etc. The newest android NDK is using a cmake based build system with a provided toolchain for cmake. For Android it will also have the API headers in the path where the toolchain can look it up. I am trying to understand what a standalone toolchain means.Ī toolchain which is ready to use with all the configuration that is the system headers and libraries in the correct path. ![]()
