Re: How to build Ubuntu Touch for Nexus 4

  Thread Previous • Date Previous • • Thread Next 
Hi David,
After getting the repositories as described in https://wiki.ubuntu.com/Touch/AndroidDevel (saucy replaced by trusty) I still have no folder called devices/lge/mako. Basically it looks the same as after calling "phable-dev-bootstrap".
Calling "breakfast mako" then complains that it can't find device mako and fetches a device repository from phablet.ubuntu.com. After that I have a folder device/lge/mako. But breakfast at the end still is complaining that it does not have a product spec "cm_mako."
Calling "breakfast mako" again yields the same error "device mako not found", it again tries to fetch the device repository, but detects that it already has one. Nevertheless, is still misses the spec "cm_mako".
"breakfast" also complains about missing jdk6. I thought that no Java bits are needed to build Ubuntu Touch (as the build instructions tell), so I'm again a bit confused - now I don't know if "breakfast" did all what it needed to do before the next can be started. 

At least cm_mako obviously is needed for the build, so it can't go on here.

Any help would be very welcome.

Regards,
Mathias

You're right, I had couple of trouble here too.
In fact there is a clue in the Ubuntu porting guide:
" You can check out the source code using the repo and git tools already
familiar to Android ROM developers, as described here

https <https://wiki.ubuntu.com/Touch/AndroidDevel>://
<https://wiki.ubuntu.com/Touch/AndroidDevel>wiki.ubuntu.com
<https://wiki.ubuntu.com/Touch/AndroidDevel>/Touch/
<https://wiki.ubuntu.com/Touch/AndroidDevel>AndroidDevel
<https://wiki.ubuntu.com/Touch/AndroidDevel>
"
Go to this link and follow the direct checkout section. Replace saucy
repo with trusty.

Once done proceed like the CM guide, it should be steps like (I don't
remember exactly):
source ./build/setenv...
breakfast mako
extract binaries
brunch mako

Good luck

    Hi David,

    please correct me if I'm wrong, this surely helps to understand the
    build process better, but it does not give me the sources to build
    Ubuntu Touch. As I understood, the phablet-dev-bootstrap tool is
    meant to provide a source tree that is based on the CyanogenMod
    sources, but reduced by everything not needed for Ubuntu Touch
    (Dalvik etc.), extended by stuff that OTOH Ubuntu Touch needs.

    So if I follow the CM instructions, I need a further step that turns
    the CM source tree into an Ubuntu Touch source tree.

             Can you add '--sources aosp' to that?

             No misunderstanding; it just hasn't been updated; That part
        of the
             instructions is outdated (follos CyanogenMod's way of doing
        things).

             You basically need to follow
        http://source.android.com/__source/building-devices.html#__obtaining-proprietary-binaries
        <http://source.android.com/source/building-devices.html#obtaining-proprietary-binaries>

             Thanks for the hint; I'll update the wiki.
