This repository contains both uptodate -c6 and the older -f10 ports. It is my intention to bring the Linux emulation on FreeBSD up to scratch. As this progresses I will fill this repo with more and more -c6 ports, all while maintaining compatibility with the Fedora 10 ports we already have inside of the ports infrastructure.

For further details read the corresponding Chapter 11. Linux Binary Compatibility of the FreeBSD Handbook.

You will need to make sure you have latest ports tree before you attempt to install the ports listed here. I recommend using subversion, as this way you will be able to easily revert changes that might have gone wrong. The FreeBSD Handbook, in particular Chapters 5 and Appendix A.5, document how to get the portstree with subversion.

First you should uninstall linux-f10* ports and its dependencies. To make it easier, you can use pkg(8) for that purpose:

    # pkg delete -f linux-f10-\*
    # pkg delete -f linux_base-f10

If you have not yet worked with Linux emulation, load the linux kernel module:

    # kldload linux

To make the change permanent, add the module to your /etc/rc.conf kld_list:

    # echo 'kld_list="linux" >> /etc/rc.conf

Proceed to change the compatibility level of the Linux kernel OS release by running the following command: asdf

    # sysctl compat.linux.osrelease=2.6.18

To make the change permanent, add this sysctl(8) variable to /etc/sysctl.conf:

    # echo 'compat.linux.osrelease=2.6.18' >> /etc/sysctl.conf

Once these preliminaries are done, you will need to merge the linux-ports from this repo into your portstree in /usr/ports (without moving the .git subdirectory) with the following command:

    git clone https://github.com/xmj/linux-ports.git
    rsync -av --exclude=.git/ linux-ports/ /usr/ports/

Now, install the actual linux base - emulators/linux_base-c6:

    # portmaster emulators/linux_base-c6

Congratulations, you can now chroot into /compat/linux and play around with it.

    # chroot /compat/linux /bin/sh

Many linux programs depend on linprocfs(5) or linsysfs(5), so it's advised to load both. Once the modules are loaded, you can mount the respective filesystems:

    # kldload linprocfs
    # mount -t linprocfs linprocfs /compat/linux/proc
    # kldload linsysfs
    # mount -t linsysfs linsysfs /compat/linux/sys

To make this change permanent, add these two lines to /etc/fstab:

    linprocfs      /compat/linux/proc     linprocfs         rw      0       0
    linsysfs       /compat/linux/sys      linsysfs         rw      0       0

and amend your /etc/rc.conf to include the modules:

    KLD_LIST="linux linsysfs linprocfs"

As I've received multiple reports of sound issues, here's how I setup sound with ALSA (on FreeBSD and Linux):

Install audio/linux-c6-alsa-plugins-oss:

    # portmaster audio/linux-c6-alsa-plugins-oss

Then, customize /compat/linux/etc/alsa/pcm/pcm-oss.conf to match your sound configuration. The default should work on all systems, but you may have to adapt paths to /dev/dsp and /dev/mixer.

If you've followed this guide from top to bottom, you by now have copied the required ports into your tree, installed linux_base-c6, loaded kernel modules, and adapted your sound configuration.

To install Skype, run

    # portmaster net-im/skype4

As with Skype, if you've followed this guide from top to bottom, you'll be all set.

To install Flash, run

    # portmaster www/linux-c6-flashplugin11 www/nspluginwrapper

and follow the instructions displayed after install. You'll have to run this for each user that is intended to run Flash:

    $ nspluginwrapper -v -a -i

or, if you are performing an upgrade,

    $ nspluginwrapper -v -a -u

Besides following the CentOS 6.5 installation described above, I'm not aware of any additional steps.

    # portmaster editors/sublime

FreeBSD's Intel KMS drivers lack the Hardware Context required by Mesa 9.2. This is a work in progress and will be added in due time. Meanwhile, we do lack the Hardware Acceleration and Google Earth will be painfully slow.

Note: I'm not sure if this applies to NVIDIA or ATI boards as well. I appreciate every report to the contrary.
