Guest Additions Installation/Usage Instructions for Haiku

---

These are temporary instructions for those who want to test the Haiku port of the guest additions before a proper package or installer has been created.

You will need:

• The contents of this repository
• A GCC4-based Haiku installation with development tools installed

(Partial GCC2/GCC2h support is present but not yet usable.)

To compile the guest additions:

export PATH=$PATH:/path/to/vbox/source/kBuild/bin/haiku.x86 ./configure --build-headless --disable-python --disable-java kmk VBOX_ONLY_ADDITIONS=1 VBOX_WITH_ADDITION_DRIVERS=1 VBOX_USE_GCC4=1 all

If the build fails complaining about 'ev' being undefined, edit out/haiku.x86/release/revision.kmk and change 'ev' to 9001 - this is due to the code for finding the Subversion revision not working with Git repos.

To install:

# core drivers mkdir -p ~/config/add-ons/kernel/generic/ cp out/haiku.x86/release/bin/additions/vboxguest ~/config/add-ons/kernel/generic/ mkdir -p ~/config/add-ons/kernel/drivers/dev/misc/ cp out/haiku.x86/release/bin/additions/vboxdev ~/config/add-ons/kernel/drivers/bin/ ln -s ../../bin/vboxdev ~/config/add-ons/kernel/drivers/dev/misc/

# video mkdir -p ~/config/add-ons/accelerants/ ~/config/add-ons/kernel/drivers/dev/graphics/ cp out/haiku.x86/release/bin/additions/vboxvideo ~/config/add-ons/kernel/drivers/bin/ ln -s ../../bin/vboxvideo ~/config/add-ons/kernel/drivers/dev/graphics/ cp out/haiku.x86/release/bin/additions/vboxvideo.accelerant /boot/system/add-ons/accelerants/

# vboxsf mkdir -p ~/config/add-ons/kernel/file_systems/ cp out/haiku.x86/release/bin/additions/vboxsf ~/config/add-ons/kernel/file_systems/

# mouse cp out/haiku.x86/release/bin/additions/VBoxMouse ~/config/add-ons/input_server/devices/ cp out/haiku.x86/release/bin/additions/VBoxMouseFilter ~/config/add-ons/input_server/filters/

# services mkdir -p /boot/apps/VBoxAdditions/ cp out/haiku.x86/release/bin/additions/VBoxService /boot/apps/VBoxAdditions/ cp out/haiku.x86/release/bin/additions/VBoxTray /boot/apps/VBoxAdditions/ cp out/haiku.x86/release/bin/additions/VBoxControl /boot/apps/VBoxAdditions/ ln -sf /boot/apps/VBoxAdditions/VBoxService ~/config/boot/launch

To uninstall:

rm -f ~/config/add-ons/input_server/devices/VBoxMouse rm -f ~/config/add-ons/kernel/drivers/bin/vboxdev rm -f ~/config/add-ons/kernel/drivers/dev/misc/vboxdev rm -f ~/config/add-ons/kernel/drivers/bin/vboxvideo rm -f ~/config/add-ons/kernel/drivers/dev/graphics/vboxvideo rm -f ~/config/add-ons/kernel/file_systems/vboxsf rm -f ~/config/add-ons/kernel/generic/vboxguest rm -f ~/config/add-ons/accelerants/vboxvideo.accelerant rm -rf /boot/apps/VBoxAdditions

Usage:

Time synchronization and guest control are handled by VBoxService - you do not need to do anything special to enable these. See the output of

VBoxManage help guestcontrol exec

on your host system for guest control instructions.

Clipboard sharing and automatic screen resizing are handled by VBoxTray; load the replicant by running /boot/apps/VBoxAdditions/VBoxTray. It will be automatically reloaded whenever Deskbar starts until you quit it by right-clicking it and choosing 'Quit'.

To mount a shared folder, tell Haiku to mount a null filesystem of type 'vboxsf' and pass the share name as a parameter:

mount -t vboxsf -p SharedFolderFullOfLolcats /mountpoint
