Cross-Compilation of freepascal on Android

Background: 1: I have an XP (Intel processor) notebook and installed Ubuntu 10 on a virtual machine.

2. FPC is 2.4.2 Lazarus version 0.9.30 sourcery g ++ lite 2010-09 Java JDK 1.6 Android simulator 2.2

Steps:

1. Install the FPC compiler and Lazarus.

2. Download FPC-source. The link is as follows: The 'fpc-2.4.2.source.tar.gz 'onhttp: // sourceforge.net/projects/freepascal/files/source/2.4.2 /,

2.1 decompress the package. Put it under home/hotcyy/, that is, the absolute path is home/hotcyy/FPC-source.

3. Download sourcery g ++ Lite. Link: The 'ia32 GNU/Linux installer' onhttp: // www.codesourcery.com/sgpp/lite/arm/portal/release1600

3.1 run the following command on the terminal:sudo Dpkg-reconfigure
-Plow DASH: Select No.

3.2 To the file directory of the software package:chmod +x
arm-2010.09-05-arm-none-linux-gnueabi.bin

3.3 installation:./arm-2010.09-05-arm-none-linux-gnueabi.bin
My path is/home/hotcyy/codesourcery/sourcery_g ++ _ lite.

3.4 after installation, check the environment variables to verify whether the installation is successful. Run arm-None-Linux-gnueabi-GCC on the terminal
-V if the version is displayed, the installation is successful. If the installation fails, you must add the environment variable: Export Path = $ home/hotcyy/codesourcery/sourcery_g ++ _ lite/bin, alternatively, you can directly use Vim to edit environment variables.

Go to the FPC-source directory and check that the FPC-source/RTL/units/ARM-Linux file contains *. PPU ;*. o file and so on. If the problem persists, proceed to the next step.

Execute: Make
Crossall cpu_target = arm OS _target = Linux opt = "-dfpc_armel-o--Gl" crossport = "-o-" crossbindir =/home/hotcyy/codesourcery/sourcery_g ++ _ lite/ arm-None-Linux-gnueabi/bin

5. The file is generated in the/home/hotcyy/FPC-source/compilers/directory.
Ppcrosarm File

6. Compile a simple PASCAL program for helloworld.
Omitted

7
To the/home/hotcyy/FPC-source/compilers/directory: Run./ppcrosarm
-Tlinux-o--XP-fu/home/hotcyy/FPC-source/RTL/units/ARM-Linux/-FD/home/hotcyy/codesourcery/sourcery_g ++ _ Lite /ARM-None-Linux-gnueabi/bin/home/hotcyy/dev/hello. PAS

Note:-Fu is the unit path,-FD is
The compiler utilities path.

8. The hello and hello. O files are generated under the "Hello. Pas" directory.

9. after installing the android environment, start the simulator and execute :. /ADB push/home/hotcyy/dev/Hello/data/Hello (note that the path of the source file must be data /*)

10. Then execute:./ADB shell/data/Hello. Then, we can see hello World --------------- the end in the terminal.
