Qualcomm OE MSM¶

Qualcomm has released (parts of?) an OE/poky port for their MDM9615 devices. We are trying to find a building configuration as of now.

1. install 64bit ubuntu precise chroot using debootstrap
   

   debootstrap --variant=buildd --arch amd64 precise /space/oe-msm-chroot-64 http://mirror.netcologne.de/ubuntu/

2. install the following packages into the chroot
   

   apt-get install vim git build-essential diffstat texi2html texinfo subversion gawk chrpath wget

3. add 'oe' user
   

   useradd -m oe

4. mount the following directories into the chroot
   

   mount --bind /dev/shm ${CHROOT}/dev/shm
   mount --bind /proc ${CHROOT}/proc
   mount --bind /sys ${CHROOT}/sys
   mount --bind /dev/shm/ ${CHROOT}/dev/shm
   

5. enter the chroot as 'oe' user and use 'repo' to check out a specific release
   

   repo init -u git://codeaurora.org/quic/le/manifest.git -b release -m LNX.LE.2.1.1-59003-9x15.xml --repo-url=git://codeaurora.org/tools/repo.git
   repo sync
   

6. apply disable-alsa-loc-hostap.diff to remove dependencies to hostap, loc-api and alsa-intf
7. don't use the build9615 command, but:
   

   cd oe-core
   . ./build/conf/set_bb_env.sh
   bitbake -k 9615-cdp-image
   

build failures¶

currently, it will fail the lk and busybox builds:

lk fail¶

NOTE: package lk-git-r3: task do_install: Started
ERROR: Function failed: do_install (see /home/oe/oe-msm-LE2/oe-core/build/tmp-eglibc/work/armv7a-vfp-neon-oe-linux-gnueabi/lk-git-r3/temp/log.do_install.16752 for further information)

| install: cannot stat `build-mdm9615/appsboot.{mbn,raw}': No such file or directory
NOTE: package lk-git-r3: task do_install: Failed

despite the build-mdm9615/appsboot.mbn and .raw files actually
existing, but maybe in a different directory?

busybox fail¶

| /home/oe/oe-msm-LE2/oe-core/build/tmp-eglibc/work/armv7a-vfp-neon-oe-linux-gnueabi/busybox-1.18.5-r44.0/temp/run.do_configure.14962: 65: /home/oe/oe-msm-LE2/oe-core/build/tmp-eglibc/work/armv7a-vfp-neon-oe-linux-gnueabi/busybox-1.18.5-r44.0/temp/run.do_configure.14962:
Bad substitution
NOTE: package busybox-1.18.5-r44.0: task do_configure: Failed

this is really odd, as the line 65 of the given file reads

export EXTRA_CFLAGS="${CFLAGS/Os/O2}" 

with forward-slashes in the CFLAGS ?!?

missing recipes / packages¶

there are some recipes missing, hence we commented them out above.

acdbloader¶

alsa-intf requires this package, but no recipe is provided.

loc-api¶

seems to be libloc_api,

qmi-framework¶

seems proprietary, thoug an older version seems leakead at
