A project builds with no problems until I add the sqlite3 library with which I get the following build error:

/bbndk-2.0.0/target/qnx6/armle-v7/usr/lib/libsqlite3.so: undefined reference to `uncompress'
cc: /mnt/Projects/PlayBook/bbndk-2.0.0/host/linux/x86/usr/bin/ntoarm-ld error 1

Using NDK 2.0 on Kubuntu 11.10

Any suggestions on what I am not doing correctly.

Sounds like you need to add libz to your project.  The examples I've seen that have sqlite3 in their libs list also have z.

Thanks for the suggestion, but it didn't work in that the file could not be found.  

The build error message displayed was:

Build error occurred, build is stopped

Note: formating above was added manually.

Would you please send me the location of the example files using sqlite3?

You added "libz" to your libs instead of just "z".  You can see this here:

qcc -o myTracker src/main.o -lbps -lpps -lscreen -llibz -lsqlite3 -V4.4.2,gcc_ntoarmv7le -w1 -g -Wl,-z,relro -Wl,-z,now
-L/mnt/Projects/PlayBook/bbndk-2.0.0/target/qnx6/../target-override/armle-v7/lib -L/mnt/Projects/PlayBook/bbndk-2.0.0/target/qnx6/../target-override/armle-v7/usr/lib

You want -lz.  There is no such thing as liblibz.
