Building a toolchain with cmake to cross-compile for android

Question

gcc (GCC) 4.8.1 
android-ndk-r9 

Hello,

My host machine is Fedora 19 and I want to create a tool-chain for compiling programs

Answer 1

In 2020 the make-standalone-toolchain.sh approach is deprecated.

This is an updated CMakeList.txt:

set(CMAKE_SYSTEM_NAME Android)
set(CMAKE_SYSTEM_VERSION 24)
set(CMAKE_ANDROID_ARCH_ABI arm64-v8a)

PROJECT(mylib C)
CMAKE_MINIMUM_REQUIRED(VERSION 3.18.0)

SET( ${PROJECT_NAME}_CURRENT 1 )
SET( ${PROJECT_NAME}_REVISION 0 )
SET( ${PROJECT_NAME}_AGE 0 )
SET(VERSION "${${PROJECT_NAME}_CURRENT}.${${PROJECT_NAME}_REVISION}.${${PROJECT_NAME}_AGE}")


SET(SOURCES foobar.c)
ADD_LIBRARY(mylib SHARED ${SOURCES})

NOTE: For the ABI arm64-v8a CMake 3.18 is needed to detect the NDK toolchain correctly, 3.10 which is the version in Ubuntu 18.04, does not find the toolchain.
