Cross-comping zlib for ARM target

Zlib is defind as “A Massively Spiffy Yet Delicately Unobtrusive Compression Library” and used in many projects requiring compression. Here are the instructions cross-compile zlib for ARM: Download zlib1.25 wget http://cdnetworks-kr-2.dl.sourceforge.net/project/libpng/zlib/1.2.5/zlib-1.2.5.tar.gz Extract it tar xzvf zlib-1.2.5.tar.gz cd zlib-1.2.5 Configure, build and install zlib. CC=armv5tel-redhat-linux-gnueabi-gcc ./configure –prefix=/home/jaufranc/edev/rootfs make make install This will install libz.a (static library) and libz.so (dynamic library) in /home/jaufranc/edev/rootfs/lib and copy the header files to /home/jaufranc/edev/rootfs/include.

Installing an ARM Toolchain in Fedora

You can easily install an arm cross-compiler on Fedora as follows: cd /etc/yum.repos.d/ sudo wget http://ftp.linux.org.uk/pub/linux/arm/fedora/cross/cross.repo sudo yum install armv5tel-redhat-linux-gnueabi-gcc You can check the installation worked by checking the cross-compiler version [jaufranc@localhost ~]$ armv5tel-redhat-linux-gnueabi-gcc -v Using built-in specs. Target: armv5tel-redhat-linux-gnueabi Configured with: ../configure –prefix=/usr –mandir=/usr/share/man –infodir=/usr/share/info –enable-shared –enable-threads=posix –enable-checking=release –with-system-zlib –enable-__cxa_atexit –disable-libunwind-exceptions –enable-languages=c,c++ –disable-libgcj –with-sysroot=yes –enable-version-specific-runtime-libs –target=armv5tel-redhat-linux-gnueabi Thread model: posix gcc version 4.1.2 20070925 (Red Hat 4.1.2-33.fa1) This will only install the C compiler (gcc), to install the C++ compiler, run the following command: sudo yum install armv5tel-redhat-linux-gnueabi-gcc-c++ Tested in Fedora 12.

Xibo Digital Signage on ARM (Beagleboard / Overo)

Xibo (pronounced eX-E-bO) is an open source, multi-display, multi-zone, fully scheduled digital signage solution written in Python (there is also a dotnet version). This is a client /server solution that can run on Windows or Linux. If you are not familiar with Xibo you can visit http://xibo.org.uk/ or/and read my introduction XIBO: An Open Source Digital Signage Server/Client. Since I had not seen digital signage solution running on low cost ARM development platform such as Beagleboard, Pandaboard or Origen, I decided to give the Xibo python client a try using qemu to emulate Gumstix Overo COM (OMAP 3530). Porting Xibo to ARM could provide several benefits compared to x86 platform: Lower hardware cost Lower power consumption (and electricity bill) Smaller form factor allowing easier integration in displays and in transportation (e.g. buses, subway trains). Easier to implement new digital signage features such as touch screen support, 3G connectivity, location based […]
