Starting from Android 6.0 (Marshmallow), it is required to build PIC compatible shared libraries.
Shared libraries compiled with FPC 3.0 does not work on Android 6.0+ and executables does not run on Android 5.0+. To run executables on older versions of Android you need to disable PIC by passing the -Cg- switch to the compiler. But PIC executables can run only on Android 4.1+. PIC shared libraries work on any Android version (tested even on Android 1.5). By default FPC builds PIC enabled shared libraries and executables for the Android target. Therefore you can use writeln() to write to the system log. For JNI shared libraries standard output and error output are redirected to the Android system log. Therefore, if you are creating a JNI shared library, always export JNI_OnLoad, even if it is empty. The compiler treats a library as a JNI library only if the library exports the JNI_OnLoad function. The compiler and RTL do special processing for JNI shared libraries. The System unit contains some useful Android-specific functions. Shared libraries do not have argc/argv available (i.e. Actually, the list of things that are different is only growing). This makes the amount of defines manageable by avoiding if defined(linux) and not defined(android). are missing, and it generally behaves different in a few ways. a few syscalls and default library functions e.g. (Background: Android is not completely Linux compatible, e.g. The compiler does NOT define LINUX during compilation! It defines UNIX and ANDROID though. Now, when the cross-compiler is ready, you can compile programs for the Android target:Ĭ:\Develop\FPC\pp\bin\i386-win32\ppcrossarm -Tandroid testprog.pas FlC:\Program Files\Android SDK\android-ndk-r12b\platforms\android-21\arch-mips\usr\lib FlC:\Program Files\Android SDK\android-ndk-r12b\platforms\android-21\arch-x86_64\usr\lib FlC:\Program Files\Android SDK\android-ndk-r12b\platforms\android-21\arch-x86\usr\lib FlC:\Program Files\Android SDK\android-ndk-r12b\platforms\android-21\arch-arm64\usr\lib FlC:\Program Files\Android SDK\android-ndk-r12b\platforms\android-21\arch-arm\usr\lib Now create a new fpc.cfg file in folder C:\Develop\FPC\pp\bin\i386-win32 and paste into it the following text: Make clean crossall crossinstall OS_TARGET=android CPU_TARGET=arm CROSSOPT="-Cparmv7a -Cfvfpv3" INSTALL_PREFIX=C:\Develop\FPC\pp For example if you wish to build units with hardware FPU support and ARMv7a CPU use the following command: If you need to specify different compiler options for building, use the CROSSOPT parameter. #QWIKI ANDROID SOFTWARE#
Also software FPU emulation is used for ARM CPU by default. Make clean crossall crossinstall OS_TARGET=android CPU_TARGET=arm INSTALL_PREFIX=C:\Develop\FPC\ppĪfter that you should have the cross-compiler and units installed in folder C:\Develop\FPC\ppīy default all units are built with -O2 optimization switch. Open the Command line prompt and cd to the root of FPC sources folder:
In this tutorial the path is:Ĭ:\Program Files\Android SDK\android-ndk-r12b\toolchains\arm-linux-androideabi-4.9\prebuilt\windows\bin
The cross-compiler installation path: C:\Develop\FPC\ppĪdd the path to Android binutils to the PATH environment variable. FPC svn sources path: C:\Develop\FPC\fpcsrc. Android NDK path: C:\Program Files\Android SDK\android-ndk-r12b. Use the similar approach to build a aarch64-android or i386-android or x86_64-android or mipsel-android cross-compiler. But the tutorial can be applied to any system with small obvious modifications. #QWIKI ANDROID HOW TO#
This tutorial describes how to build a cross-compiler for the arm-android target on Windows. You need to have a working installation of the latest version of FPC for your host platform in order to create the cross-compiler. Now you have the latest compiler sources in the fpcsrc sub-folder. The development (trunk) version of FPC may contain new features or bug fixes compared to the latest release version.Ĭheck out the latest trunk sources of FPC using the following command:
#QWIKI ANDROID ARCHIVE#
After installation of the cross-compilers you can build binaries for Android without any additional steps.įor other host platforms you need to download the FPC sources archive and build a cross-compiler as described below.ĭownload the latest release cross-compilers and FPC sources here: Development version If you develop for Android using a Windows machine you can download a setup package which contains cross-compilers for Android (ARM, i386, MIPS).
#QWIKI ANDROID INSTALL#
You need to download and install Android NDK in order to get the cross binutils that compile programs for the android target on your current machine. ARM64 ( CPU_TARGET=aaarch64) - in FPC 3.2+.Support for the Android target is present starting from FPC 3.0. 8 Freeze during shared library initialization on Android prior 4.1.
