Native binaries are not as portable as the 'build once, run anywhere'. binaries c /tmp/android-ndk/toolchains/llvm/prebuilt/linux-x8664/bin/. Native code is built using the compiler toolchain supplied within the Android NDK. This should be enough to build the Linux version of the toolchain. Download the Android NDK from the official site and extract it somewhere on. Install the following required packages: sudo apt-get install g++-multilib Refer LINK to know more about app gradle configurations. Compiler: C:/android-ndk-r10d-windows-x8664/toolchains/x86-4.9/prebuilt/windows-x8664/bin/c++.exe Build flags: Id flags: The output was: 1 c:/android-ndk-r10d-windows-x8664/toolchains/x86-4.9/prebuilt/windows-x8664/bin/./lib/gcc/i686-linux-android/4.9/././././i686-linux-android/bin/ld.exe: error: cannot open crtbegindynamic. If you don't specify toolchain it will by default use GCC 4.9. For NDK r10e, GCC (4.8, 4.9) and Clang (3.5, 3.6) options are available. The script will automatically download sources for the most recent NDK release (not the tip of the tree). You can refer your NDK directory to know which toolchain and which versions are available. build/tools/download-toolchain-sources.sh src I used a fresh install of Ubuntu 12.04 64-bit in a virtual machine with 6GB of RAM and a large amount of disk space, in conjuction with NDK r9.ĭownload the Android NDK and extract it: tar -xf android-ndk-r9-linux-x86_64.tar.bz2ĭownload the toolchain source code. Recently, I've had to build a custom Android NDK toolchain from source.
