Missing symbols building Android on Ubuntu

Question

I followed the instructions on source.android.com to build the Android framework, but when I run the make command I get many errors. I'm running a virtualized 32-bit Ubuntu 11.04 on vmware under a 64-bit Windows Vista.

cat /proc/version

says

Linux version 2.6.38-8-generic (buildd@vernadsky) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu3) ) #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011

I have synchronized everything by using:

repo init -u https://android.googlesource.com/platform/manifest
repo sync

and I chose the full-engineering target by using:

lunch full-eng

This is a partial list of the errors I get:

Answer 1

Below is what removed these errors in my case. An offending extraneous '/' at the end.

bad:

export PATH=/home/rev/BIN/jdk-6u34/jdk1.6.0_34/bin/:$PATH

Good:

export PATH=/home/rev/BIN/jdk-6u34/jdk1.6.0_34/bin:$PATH

Answer 2

To fix this on OSX, add the Java bin directory to PATH

export PATH=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin:$PATH

PS: The jdk folder(jdk.1.7.0_51.jdk) might be different for folks as it depends on the version on jdk you have installed. Just use the jdk folder you have installed. The path to bin is the same.
