INSTALLATION OF SBOX2 ON UBUNTU 8.04

Trouble running maemo's scratchbox under Ubuntu Hardy?
I’ve been having trouble running scratchbox after upgrading to hardy. I’ve finally found some workarounds for the issues that creep up.
- For the Inconsistency detected by ld.so: rtld.c: 1192: dl_main: Assertion ‘(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso’ failed! problem, it’s necessary to disable “vdso”:
echo 0 | sudo tee /proc/sys/vm/vdso_enabled
- For problems when building packages (mmap: permission denied when building), it’s necessary to reduce the mmap minimum address:
echo 4096 | sudo tee /proc/sys/vm/mmap_min_addr
Update: (Thanks to
colinleroy):...to make these changes permanent across reboots, one can add these settings to /etc/sysctl.conf:
vm.vdso_enabled = 0
vm.mmap_min_addr = 4096
Then run
sudo sysctl -p

INSTALLATION OF SBOX2 ON UBUNTU 8.04
This is a step-by-step guide about how to install Scratchbox2 on Ubuntu 8.04.
[edit]
1. Packages
The installation requires the following packages:
- autoconf
- autogen
- automake
- autotools-dev
- binutils
- fakeroot
- gcc-3.4 (needed by Qemu)
- git-core
- g++
- libsdl1.2-dev (needed by Qemu)
- make
- sbrsh
- subversion (needed for Qemu)
So, type:
sudo apt-get install autoconf autogen automake autotools-dev binutils fakeroot gcc-3.4 git-core g++ libsdl1.2-dev make sbrsh subversion
We're going to install a custom version of Qemu, so remove any existing version of Qemu by typing:
sudo apt-get --purge remove qemu
[edit]
2. Directories
$ rm -fr $HOME/sbox2 $HOME/.scratchbox2
$ mkdir -p $HOME/sbox2 $HOME/sbox2/bin $HOME/sbox2/bin/qemu $HOME/sbox2/rootfs/armle $HOME/sbox2/src
[edit]
3. Scratchbox installation
$ cd $HOME/sbox2/src
$ git clone git://anongit.freedesktop.org/git/sbox2
$ cd sbox2
$ ./autogen.sh
$ ./configure --prefix=$HOME/sbox2/bin/scratchbox
$ make install
Edit $HOME/sbox2/bin/scratchbox/bin/sb2-build-libtool and add
--host=i386
to to the "./configure" command.
Edit $HOME/sbox2/bin/scratchbox/bin/sb2-init and remove the option
-Wno-poison-system-directories
from the SBOX_EXTRA_CROSS_COMPILER_ARGS variable.
[edit]
4. Qemu
Download Qemu:
$ cd $HOME/sbox2/src
$ svn co svn://svn.savannah.nongnu.org/qemu
Armeb support in Qemu does not work properly. To make it work a bit better, open the qemu/trunk/linux-user/syscall_defs.h file and change
abi_ulong st_blocks; /* Number 512-byte blocks allocated. */
abi_ulong __pad4; /* future possible st_blocks high bits */
to
#ifndef TARGET_WORDS_BIGENDIAN
abi_ulong st_blocks; /* Number 512-byte blocks allocated. */
abi_ulong __pad4; /* future possible st_blocks high bits */
#else
abi_ulong __pad4; /* future possible st_blocks high bits */
abi_ulong st_blocks; /* Number 512-byte blocks allocated. */
#endif
Then, install Qemu:
$ cd qemu/trunk/
$ ./configure --prefix=$HOME/sbox2/bin/qemu/
$ make
$ make install
[edit]
5. PATH variable
Edit $HOME/.bashrc and append at the end of the file the following line:
export PATH=$PATH:$HOME/sbox2/bin/scratchbox/bin:$HOME/sbox2/bin/qemu/bin
Close and re-open the console.

6. Target armle
[edit]
6.1 Toolchain
We get the toolchain from Codesourcery:
$ cd $HOME/sbox2/src
$ wget http://www.codesourcery.com/gnu_toolchains/arm/portal/package1787/public/arm-none-linux-gnueabi/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
$ tar -xvjf arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 -C $HOME/sbox2/bin/
[edit]
6.2 Rootfs
$ cd $HOME/sbox2/src
$ wget http://repository.maemo.org/stable/diablo/armel/maemo-sdk-rootstrap_4.1_armel.tgz
$ tar -xvzf maemo-sdk-rootstrap_4.1_armel.tgz -C $HOME/sbox2/rootfs/armle
[edit]
6.3 Configuration
$ cd $HOME/sbox2/rootfs/armle
$ sb2-init armle $HOME/sbox2/bin/arm-2007q3/bin/arm-none-linux-gnueabi-gcc
[edit]
6.4 Remove warnings
Since the toolchain is from CodeSourcery, we have to edit $HOME/.scratchbox2/armle/sb2.config and add the option
-Wno-poison-system-directories
to the SBOX_EXTRA_CROSS_COMPILER_ARGS variable.
[edit]
7. List of commands
- sb2 to enter sbox2
- sb2 <command> to execute a command in sbox2
- sb2 -t <target> to switch target
- sb2-config -l to have the list of targets
- sb2-config -d <target> to set default target
[edit]
8. Configuration of Laika Plugin for Eclipse
- Sandbox directory:
$HOME/sbox2/workspace
- Invoking Scratchbox commands:
cd $HOME/sbox2/workspace${directory} ; sb2 `echo ${command} | sed 's|${directory}|.|g'` ${args}
- Listing build targets:
directory=none; sb2-config -l
- The syntax for choosing a build target:
sb2-config -d ${target}
