arm-eabi-gcc: not found

When I tried to compile my own Android ROM, I got the following error:

CHK     include/linux/version.h
target Executable: skia_gm (/media/ssd/buildout//target/product/i9100/obj/EXECUTABLES/skia_gm_intermediates/LINKED/skia_gm)

make[4]: *** [scripts/mod/empty.o] Error 127
make[3]: *** [scripts/mod] Error 2
make[2]: *** [scripts] Error 2
make[2]: *** Waiting for unfinished jobs....

The problem was that the arm toolchain wasn’t installed. After installing the toolchain compiling succeeded.

Installing the toolchain can be done with the following command:
git clone https://android.googlesource.com/platform/prebuilt

After that, run the following command to add the toolchain to the PATH variable:
export PATH=$(pwd)/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH

Compiling should now succeed without the previous error.

I’ve found this information on http://source.android.com/source/building-kernels.html, a very helpful information source for Android development.

Windows 8 Upgrade troubles

I’ve purchased a Windows 8 upgrade for my Windows 7 machine. While upgrading I ran into a problem.

The upgrade came to 100%, and then said “Your computer will reboot in a few moments”. After a few minutes it came up with a general error “Windows 8 Setup could not complete” and then it closed. My computer didn’t reboot, and Windows 7 just kept on running.

After removing some applications like my virus scanner (NOD32) and some other applications i tried again. After about an hour I got exactly the same error.

Then I found the following error:
ConX::Setup::Media::CWorkerProc::SetupThreadProc: An error occurred while servicing the boot files from [C:\$WINDOWS.~BT\Windows\BOOT]; status = [0x80070015][gle=0x00000015]

After a lot of searching I’ve found the following solution:
Add a drive letter to the 100MB system partition which resides at the beginning of your harddisk. I assigned the letter S.

After I did this, the setup continued where it previously stopped with an error, and Windows 8 was installed like it should.

When Windows 8 was completely installed, I removed the drive letter from the partition. After this, Windows 8 was running flawlessly.

Tweetdeck on Windows 8

tweetdeck-02-676x535I’ve recently upgraded my Windows 7 installation to Windows 8. Unfortunately Tweetdeck wouldn’t connect to my account anymore and showed the not so useful error “Unable to connect”.

After a lot of searching I’ve found a simple and unlogical solution:

  1. Start Internet Explorer
  2. Navigate to https://api.tweetdeck.com
  3. Navigate to https://twitter.com
  4. Close Internet Explorer
  5. Start Tweetdeck
  6. Log in to your account

Now Tweetdeck works like it should, and profile images should appear again.

Yum hangs at “Running Transaction Test”

When installing a package via Yum, the process stalled at “Running Transaction Test”.

After a lot of digging, I found that the problem was a stale NFS mount.
After unmounting this mount with the command below, Yum worked flawlessly again.
umount -l /mnt/sharename

Disable emails in Moodle

For Moodle development I occasionally clone a production environment to a temporary test location. This way I know for certain that my custom code works in the environment it should work in.

The downside of this approach is that notifications are still mailed to users. So after a bit of searching in the Moodle docs I have found no solution. So I went digging in the code, and found a configuration option that prevents the Moodle installation to send emails completely. All you have to do is put the following setting in your settings.php.
$CFG->noemailever = true;

Tip: A lot of settings are also described in the config-dist.php file in the root folder of your Moodle installation.
