NAME

sb2 - crosscompiling environment

SYNOPSIS

sb2 [options] [command] [arguments] [...]

DESCRIPTION

sb2 Runs command in scratchbox2. If no command is given, a bash shell in scratchbox2 environment is started.

OPTIONS

-v

Display version number.

-L LEVEL

Enable logging. Following values for logging LEVEL are available: error, warning, notice, info, debug, noise, noise2.

-d

Use debug mode: log all redirections (logging LEVEL=debug) to log file under directory $HOME/sb2_logs .

-h

Print help.

-t TARGET

Define TARGET to use. Use sb2-config -d TARGET to set a default.

-e

Use emulation mode, avoid executing any host binaries except qemu.

-m MODE

Use mapping mode MODE given in argument. Following MODE values are supported: devel, emulate, install, simple, tools.

-M FILE

Read mapping rules from FILE.

-s DIRECTORY

Use redirection rules from the DIRECTORY given in argument.

-Q BUGLIST

Emulate bugs of the scratchbox 1 (BUGLIST consists of letters: 'x' enables exec permission checking bug emulation).

-r

Disable creating reverse mapping rules: functions like getcwd() and realpath() will always return the real path.

-O OPTIONS

Set options for the selected mapping mode. OPTIONS is a mode-specific string.

-R

Execute commands in fakeroot environment.

-S FILE

Create a persistent session: Write session information to FILE

-J FILE

Join a persistent session assossiated with FILE.

-D FILE

Delete a persistent session assosiated with FILE. Warning: this does not check if the session is still in use!

-W DIR

Use DIR as the session directory when creating the session (The default is to create the session in /tmp). DIR must be an absolute path and must not exist. Note that long pathnames may cause trouble with socket operations, so try to keep DIR as short as possible.

-c

When creating a session, also create a private copy of target_root (rootstrap). Note that this can be really slow, depending on the size of the orig.target_root.

-C DIR

When creating a session, create copy of DIR and use it as the target_root (rootstrap). Note that this can be really slow. See alse option -c.

-T DIRECTORY

Use DIRECTORY as tools_root (override the value which was specified to sb2-init when the target specification was created).

EXAMPLES

sb2 ./configure

sb2 make

sb2 -eR make install

sb2 -R -m emulate make install

CONFIGURATION

To configure sb2, do something like this:

 mkdir $HOME/buildroot
 cd $HOME/buildroot
 [fetch a rootfs from somewhere and extract it here]
 sb2-init -c qemu-arm TARGET /path/to/cross-compiler/bin/arm-linux-gcc
 

To change default scratchbox2 target:

sb2-config -d another_target

FILES

~/.scratchbox2/config
