Compiling cupcake with some changes for the G1 (HTC Dream)

Currently working on some random things on the Android OS source - which of course if I can get my little, “additions”, to work properly I’ll be releasing them. Though I was having a few problems getting the code to compile - so I figured I’d throw together this post just in case anyone else is having similar trouble.

Essentially in the post I was originally reading here, stated the following;

At the time of writing, the Android Dream build was broken. I needed to do the following to make it work:
* Several (relatively minor) changes in the Dream audio driver code to fix compilation issues.
* Copied libOmxCore.so to mydroid/out/target/product/dream/system/lib (this was a missing step in the Building for Dream documentation, and something that should be in the HTC provided script)

Well that wasn’t the problem I was getting though – the error I had been getting was actually:

In file included from frameworks/base/libs/audioflinger/AudioResamplerCubic.cpp:20:

(This list was compiled over multiple re-runs of make)

The simple fix was essentially what was stated in the original post, though it just took me a few minutes to figure this out. After running the locate command like a mad man and not finding anything on my developer machine, I finally reread everything and checked the device for the file – and there it was!

I just ended up throwing this into my extract-files.sh;

adb pull /system/lib/libaudio.so proprietary/libaudio.so
adb pull /system/lib/libcamera.so proprietary/libcamera.so
adb pull /system/lib/libOmxCore.so proprietary/libOmxCore.so
adb pull /system/lib/librpc.so proprietary/librpc.so

So my resulting file looked like this;

#!/bin/sh

mkdir -p proprietary
adb pull /system/etc/AudioFilter.csv proprietary/AudioFilter.csv
adb pull /system/etc/AudioPara4.csv proprietary/AudioPara4.csv
adb pull /system/etc/gps.conf proprietary/gps.conf
adb pull /system/bin/akmd proprietary/akmd
adb pull /system/lib/libhtc_ril.so proprietary/libhtc_ril.so
adb pull /system/lib/libaudioeq.so proprietary/libaudioeq.so
adb pull /system/lib/libqcamera.so proprietary/libqcamera.so
adb pull /system/lib/libaudio.so proprietary/libaudio.so
adb pull /system/lib/libcameraservice.so proprietary/libcameraservice.so
adb pull /system/lib/libcamera.so proprietary/libcamera.so
adb pull /system/lib/libOmxCore.so proprietary/libOmxCore.so
adb pull /system/lib/librpc.so proprietary/librpc.so
chmod 755 proprietary/akmd

adb pull /system/etc/wifi/Fw1251r1c.bin proprietary/Fw1251r1c.bin
adb pull /system/etc/wifi/tiwlan.ini proprietary/tiwlan.ini

libaudio.so, libcameraservice.so, libcamera.so, libOmxCore.so, librpc.so then needed to be copied over to TARGET/dream/target/product/dream/obj/lib/ and also to the locked folder TARGET/dream/target/product/dream/system/lib/

Ta-da! After approximately 10 runs, it finally compiled for me… Hopefully this helps anyone who ran into the same problems as me.
