How to cross compile Microwindows for ARM arch

srg_btl · 04-09-2013, 02:02 PM

Hello! Have some problem with cross-compile of Microwindows.
Here are my steps:
0. Download cross-compile toolchain

Code:

wget http://www.codesourcery.com/sgpp/lite/arm/portal/package5383/public/arm-none-linux-gnueabi/arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
sudo mkdir –p /opt/toolchain
sudo cp arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 /opt/toolchain
cd /opt/toolchain
sudo tar –jxvf arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
export PATH=/opt/toolchain/arm-2009q3/bin:$PATH

1. Download last version (v. 0.92) of Microwindows

Code:

	
cd ~
wget ftp://microwindows.censoft.com/pub/microwindows/microwindows-full-0.92.tar.gz
	tar xvf microwindows-full-0.92.tar.gz

2. Pre-configuration: install next packages:

Code:

	
sudo apt-get install libjpeg-dev libpng-dev python-dev libfreetype6-dev

3. Edit config file for ARM architecture

Code:

cd microwindows-0.92/src
nano config

And edited next lines:

Code:

ARCH                     = LINUX-ARM
ARMTOOLSPREFIX           = arm-none-linux-gnueabi-	
INCJPEG                  = /usr/include/
INCPNG                   = /usr/include/
INCZ                     = /usr/include/
INCTIFF                  = /usr/include/
LIBFT2LIB                = /usr/lib/libfreetype.a

4. Run make

After then I have next messages:

Code:

cc1: warning: include location "/usr/include/" is unsafe for cross-compilation
cc1: warning: include location "/usr/include/freetype2" is unsafe for cross-compilation

make: *** [subdir-/home/user/microwindows-0.92/src/mwin] Error 2

What's wrang? And how I can fix it?

What's in the cross compile toolchain?

You need arm kernel headers, a libc, and a compiler. The kernel headers are includes in /usr/include. It seems to be reading your x86 ones. Then try

CC=/path/to/arm/compiler
./configure --includedir=/opt/toolchain/include --libdir=/opt/toolchain/lib
(guessing wildly here)
to point the configure at your arm ones. Better getting a guide on this. But you get the idea - the syustem is going to reach for the x86 stuff automatically.

And :

Quote:

sudo apt-get install libjpeg-dev libpng-dev python-dev libfreetype6-dev

.. those packages cannot be used for arm.

All dependencies for Microwindows must be cross compiled for arm
to e.g. /opt/cross**, before you start the Microwindows build.
