How to cross compile Microwindows for ARM arch

Question

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


    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

Download last version (v. 0.92) of Microwindows

   

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

Pre-configuration: install next packages:

   

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

Edit config file for ARM architecture


    cd microwindows-0.92/src
    nano config

And edited next lines:

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

Run make

After then I have next messages:

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

You are specifying your host's (i.e. local not target's) environment for include directories. Have you previously cross-compiled anything else (e.g. hello_world.c) with your toolchain? Consider using a development environment like Buildroot or Openembedded. — sawdust
Yes, hello world and some other sources with my toolchain are compiled successfuly. Thanks. — Sergiy Baitala

First you need source-code of all dependency library and CROSS-COMPILE libjpeg-dev libpng-dev python-dev libfreetype6-dev and other dependency libraries.

Then while compiling microwindow, path of include and library must be updated in Makefile where your cross-compiled libraries present.
