patch diff rpm

http://bradthemad.org/tech/notes/patching_rpms.php

Summary:

% diff -uNr package-1.0/ package-1.0p/ > ../SOURCES/package-1.0-my.patch

• Adding the patch to the package

Next, add the patch to the specfile, so it will be applied when building the package. There may be other patches already, and they are applied in order of their number in the specfile, so number yours appropriately. Add to %_topdir/SPECS/package.spec, in the top section where the name, version, and source lines are:

Patch0: package-1.0-my.patch

Farther down, there will be a section that deals with preparing for the build. Add a patch command that corresponds with the patch line above, typically right after %setup:

%prep
%setup ...
%patch0 -p1

puppet mirror

Missing Info from Android Building Your First App Tutorial

The android tutorial for "Build Your First App" (http://developer.android.com/training/basics/firstapp/index.html) is excellent, but they leave a couple of things out that I had to figure out for myself.  I am developing on ubuntu linux and following the command line version of the tut.  When I got to this part of the tut:

http://developer.android.com/training/basics/firstapp/running-app.html

I ran into the error "could not find javac" when I ran "ant debug".
I had to install javac like so ...

$ sudo apt-get install openjdk-6-jdk

The next problem was that I kept getting ...


error: device not found
- waiting for device -

... when I executed:

red@ubuntu:~/android/workspace/MyFirstApp$ adb install bin/MyFirstApp-debug.apk


... I found out that I need to start the "server" like so ....


red@ubuntu:~/android/workspace/MyFirstApp$ adb kill-server
red@ubuntu:~/android/workspace/MyFirstApp$ adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
red@ubuntu:~/android/workspace/MyFirstApp$ adb install bin/MyFirstApp-debug.apk
