Notes on porting DFB-GTK to MINI2440

1. Development Environment

Host: debian5.0

Host gcc version: gcc (Debian 4.3.2-1.1) 4.3.2

Cross compiler: arm-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

Cross compiler download address:

http://www.codesourcery.com/sgpp/lite/arm/portal/release1293

2. Host Software

Since some host software is needed in the cross-compilation process, install it first to avoid problems when compiling later. Since all the software packages used in this cross-compilation are the latest versions, the host software should also use the latest version to avoid problems due to version matching.

1. Autoconf

autoconf-2.68.tar.bz2

2. Automake

automake-1.11.tar.bz2

3. Libtool

libtool-2.4.tar.gz

4. Ncurses

ncurses-5.7.tar.gz

5. Zlib

zlib-1.2.5.tar.bz2

6. Tiff

tiff-3.8.2.tar.gz

7. Libpng

libpng-1.4.4.tar.gz

8. Libjpeg

jpeg-8b.tar.gz

9. Gettext

gettext-0.18.1.1.tar.gz

10. gdk-pixbuf

gdk-pixbuf-2.22.0.tar.bz2

11. glib

glib-2.26.0.tar.bz2

All software version numbers are provided above. After downloading the above source code, install the above tools from source code on Linux. The unified steps are: unzip the source code, configure, make, make install.

It should be noted that when configuring, add the --prefix=/usr parameter, otherwise some tools may not be found during cross-compilation later; in addition, root privileges are required when executing makeinstall.

3. Cross-compilation

First, execute the following command in the terminal to initialize some environment variables and prepare for cross-compilation:

exportCC="arm-none-linux-gnueabi-gcc -mabi=aapcs-linux -march=armv4t"

exportCXX="arm-none-linux-gnueabi-g++ -mabi=aapcs-linux -march=armv4t"

exportPKG_CONFIG_PATH=/mnt/nfs/lib/pkgconfig

exportCPPFLAGS=-I/mnt/nfs/include

exportCFLAGS=-I/mnt/nfs/include

exportCXXFLAGS=-I/mnt/nfs/include

exportLDFLAGS=-L/mnt/nfs/lib

CC and CXX are the cross-compilers of gcc and g++ respectively, and -mabi=aapcs-linux –march=armv4t is added at the end because the cross-compiler we downloaded is output according to the armv5 architecture by default, which cannot run on mini2440. In addition, the target address of our installation is /mnt/nfs, so first create an nfs directory with write permission for ordinary users under your /mnt directory.

1. Tslib

Tslib download address: http://github.com/kergoth/tslib

The package I downloaded is kergoth-tslib-1.0-45-gd9ff92d.tar.gz. Unzip the package, then go to the source directory and run the following command:

./autogen.sh

After completion, run the following command to configure:

./configure --prefix=/mnt/nfs

    --build=i686

    --host=arm-none-linux-gnueabi

    --enable-shared

    --disable-static

    --enable-linear

    --enable-dejitter

    --disable-linear-h2200

    --enable-variance

    --enable-pthres

    --disable-ucb1x00

    --disable-cy8mrln-palmpre

    --disable-corgi

    --disable-collie

    --disable-h3600

    --disable-mk712

    --disable-arctic2

    --disable-tatung

--enable-input

       If everything is OK, run make, and then run make install.

2. Zlib

zlib-1.2.5.tar.bz2, download address is zlib.net

After decompression, enter the source directory and configure the command:

./configure --prefix=/mnt/nfs –shared

Then make; make install

3. Libpng

libpng-1.4.4.tar.gz

Download address: http://www.libpng.org/pub/png/libpng.html

After decompression, enter the source directory and configure the command:

./configure --prefix=/mnt/nfs

--build=i686

--host=arm-none-linux-gnueabi

      --enable-shared

Then make; make install

4. Libjpeg

jpeg-8b.tar.gz

Download address: http://artfiles.org/sunfreeware.com/pub/freeware/SOURCES/jpeg-8b.tar.gz

Unzip and enter the source code, configure the command:

./configure --prefix=/mnt/nfs

    --build=i686

    --host=arm-none-linux-gnueabi

--disable-static

       Then make; make install

5. Freetype

freetype-2.4.3.tar.bz2

Download address: http://sourceforge.net/projects/freetype/files/

After decompression, enter the source directory and configure the command:

./configure --prefix=/mnt/nfs

    --build=i686

    --host=arm-none-linux-gnueabi

--disable-static

       Then make; make install

6. Directfb

DirectFB-1.4.6.tar.gz

Download address: http://www.directfb.org/downloads/Core/DirectFB-1.4/DirectFB-1.4.6.tar.gz

Compiling directfb requires support for fusion header files, and the kernel must also have fusion support.

linux-fusion-8.1.2.tar.gz

Download address: http://www.directfb.org/downloads/Core/linux-fusion/linux-fusion-8.1.2.tar.gz

Add the downloaded fusion to the kernel. You can refer to the documentation for details on how to add it. Then, extract the fusion.h header file and put it in the /mnt/nfs/include/linux directory. If there is no fusion.h header file in the /mnt/nfs/include/linux directory during configure, directfb will use its own internal fusion. I have used this method but it did not work, so be sure to use a separate fusion module.

After decompressing directfb, enter the source directory and configure the command:

./configure --prefix=/mnt/nfs

    --build=i686

    --host=arm-none-linux-gnueabi

    --disable-osx

    --disable-x11

    --disable-network

    --enable-multi

    --enable-fbdev

    --enable-zlib

    --disable-gif

    --disable-vnc

    --with-gfxdrivers=none

--with-inputdrivers=tslib,keyboard

Even if there is no keayboard on your platform, you still need to add this kerboard, otherwise there will be an error of can't get request id when starting the gtk application.

After configuration is complete, make; make install

4. Preparation before operation

1. pango configuration

Create a pango directory in the /mnt/nfs/etc/ directory of the development board, and then run the following commands on the development board:

pango-querymodules> /mnt/nfs/etc/pango/pango.modules

The pango-querymodules are generated in the /mnt/nfs/bin directory of the host machine when the pango library is compiled. You can run it by copying it directly from this location to the development board.

2. Fonts

After the compilation is complete, there will be a fonts.conf file in the /mnt/nfs/etc/fonts directory of the host machine. Put this file in the /mnt/nfs/etc/fonts directory of the development board.

3. Fonts

According to the configuration of the host machine, create a truetype directory in the /usr/share/fonts directory of the development board, and put the ttf font library into this directory.

After finishing the above work, the gtk hello world program can be run. However, there are still some problems with the operation of gtk3-demo, which will cause the signal 11 problem. The specific solution needs further research.

This document is a preliminary document, just the first step to successfully run gtk. I hope to have the opportunity to improve the more complete document in the future. If you are interested, please contact me and study it together. Contact information is in my personal profile.
