hi Florian,

have a look at: https://genode.org/documentation/release-notes/13.11 it could help you to run genode on RPI.

best,

The description from those release notes is pretty much outdated. Please, follow the following steps:

# create a build directory, e.g.:

tool/create_builddir hw_rpi

# prepare the dde_linux and libc 3rd-party code:

tool/ports/prepare_port dde_linux libc

# change to the build-directory:

cd build/hw_rpi

# uncomment the dde_linux and libports repositories in the # build-directory's 'etc' directory:

sed -i 's/#(.*/libports)/\1/' etc/build.conf sed -i 's/#(.*/dde_linux)/\1/' etc/build.conf

# start the demo run script:

make run/demo

After the successful build the resulting ELF image file resides in:

var/run/demo/image.elf

To create an u-boot image, you can additionally add a RUN_OPT variable to your build.conf file:

echo "RUN_OPT += --include image/uboot" >> etc/build.conf

Of course, you then need to re-build the demo scenario. The resulting image will reside in:

var/run/demo/uImage

Hello, community,

first of all: let me express, how helpful and responsive this
mailing list is. I finally succeeded in running make for hw_rpi -
still I have no idea how to run it on my real hardware. make surely
created many files, most of them object files (.o), or object
archives (.a). For running on my hardware, I would need an image
file, which I can write on an SD card, though. How would I create
one? Browsing through the .txt files didn't yield to anything useful.

I also have another concern when making for target linux_x86
according to section 'Quick start to build genode for linux'. make
run/demo quits with the following errors:

If I run make without any arguments, the adio_drv doesn't build. The
linker quits with the following messages:

Any hints would be greatly appreciated.

All the best, Florian.

Thank you, Christian. Adding -no-pie to the compiler flags fixed this issue.

Dear Stefan, Dear Mohammad,

thank you for your kind support. Stefan pointed me into the right direction. I was missing, that I had to uncomment two directories in the build.conf and that I needed to make the run/demo target. The result was an elf file. I assume that this needs to be loaded by the Raspberry bootloader. I will give it a try as soon as I get some spare time on my hands, maybe next weekend. However, I don't expect any troubles here.

The other matter appears a little tricker, though.

I am using a 64-bit SDL-1.2 (the build manual didn't specify, whether to use SDL-1.2 or SDL-2.0, but I guessed from the sources that it must be 1.2): florian@...465...:~/genode/build/linux_x86$ file /usr/lib/x86_64-linux-gnu/ libSDL-1.2.so.0.11.4 /usr/lib/x86_64-linux-gnu/libSDL-1.2.so.0.11.4: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]= fb5912d243b188e293346fd4ce1e09d5ed2d1fe2, stripped

My libalsa is also 64 bits: florian@...465...:~/genode/build/linux_x86$ file /usr/lib/x86_64-linux-gnu/ao/plugins-4/libalsa.so

/usr/lib/x86_64-linux-gnu/ao/plugins-4/libalsa.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]= 5f11394919125b4879e2b15cc6d32a2c4b2976b1, stripped

I am running Ubuntu 16.10 64 bits in a Virtual Box on a Windows 10 host: florian@...465...:~/genode/build/linux_x86$ uname -a Linux Linde 4.8.0-30-generic #32-Ubuntu SMP Fri Dec 2 03:43:27 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

However, there is no specs.conf file in my build directory: florian@...465...:~/genode/build/linux_x86$ ls -R -a .: . .. etc Makefile

./etc: . .. build.conf

Do I need to create one?

Regards, Florian.
