ffmpeg is optimized for ARMv7 Cortex a8 with neon by default and obviously fails to build for armv6, here are the steps to fix this issue:.

Simply edit src/v8/tools/gyp/v8_ and v8/tools/gyp/v8_ and comments out cflags and lflags lines with -m32.Failure to do so will result in the following error:Ĭc1plus: error: unrecognized command line option “-m32” This flag is also not necessary for ARM since up to now only 32-bit is supported.

Some v8 makefiles will add “-m32” flags to target builds, this is not supported by the compiler and breaks the build.

This will greatly help in case the build fails. You may also want to “export V=1” in order to see the arm-linux-gnueabi-xxx command lines used. Once this is done, source the environment variables:.'arm_fpu': 'vfp', # Optional, to select which version of vfp to use if NEON is off. 1 is the default, and most people want to keep it that way. 'arm_neon': 0, # Optional, to disable NEON. 'arm_thumb': 0, # Optional, for targeting thumb. 'armv6': 1, # Optional, for targeting ARMv7. 'armv7': 0, # Optional, for targeting ARMv7. 'linux_use_tcmalloc': 0, # tcmalloc does not build for ARM. 'disable_nacl': 1, # NaCL does not build for ARM. You may also need to create or edit ~/.gyp/include.gypi with the following:.arm.env) with the environment variables required to build chromiumĮxport CFLAGS=”-I/usr/arm-linux-gnueabi/include/gtk-2.0 -I/usr/arm-linux-gnueabi/include/glib-2.0 -march=armv6 -mfpu=vfp -mfloat-abi=softfp”Įxport CXXFLAGS=”-I/usr/arm-linux-gnueabi/include/gtk-2.0 -I/usr/arm-linux-gnueabi/include/glib-2.0/ -I/usr/arm-linux-gnueabi/lib/glib-2.0/include/ -I/usr/arm-linux-gnueabi/include/pango-1.0 -I/usr/arm-linux-gnueabi/include/cairo/ -I/usr/arm-linux-gnueabi/include/librsvg-2 -O3 -march=armv6 -mfpu=vfp -mfloat-abi=softfp”Įxport GYP_DEFINES=”target_arch=arm disable_nacl=1 linux_use_tcmalloc=0 armv6=1 arm_thumb=0 use_libjpeg_turbo=0 chromeos=1″ Gclient sync -deps="unix,chromeos" -force

#CHROMIUM OS RASPBERRY PI INSTALL#

Install required armel libraries with xapt:.

Sudo apt-get install build-essential git-core subversion cmake doxygen gyp libudev-dev g++-multilib libssl-dev

Install some tools and libraries on the host machine:.

Install emdebian toolchain (including xapt and dpkg-cross).The steps to build the Chromium browser are similar, simply remove chromeos=1 in the instructions below.

The steps provided below are only to build the Chromium OS binaries file, the kernel and rootfs would also have to be generated and packaged to get a full image. A 64-bit OS is necessary to be able to build the debug version of Chromium OS.

#CHROMIUM OS RASPBERRY PI PC#

A PC based on a Intel Core i7 950 CPU 3.06 GHz (Quad core) with 4 GB RAM, 6 GB swap and running Debian Squeeze 64-bit. Please note that although it can build, it still does not run properly and a few more changes are needed.įirst, you’ll need a fast machine to build Chromium OS in a reasonable amount of time. Today, I’ll post the steps followed to build Chromium OS LKGR (“the latest revision to pass only unit tests”) optimized for ARMv6 processor with soft-float support, which is the type of processor (Broadcom BCM2835) used in the Raspberry Pi. Recently I’ve been contacted by hexxeh, who maintains Chromium OS vanilla builds for x86 and MacOS computer, as he intends to provide Chromium OS for the Raspberry Pi, and you should be able to get a SD card image once everything is working from the site above. I had previously written the instructions to build an older version of Chromium (via Berkelium) for ARM using Beagleboard/Overo rootfs in order to use it with Xibo digital signage.
