I have been using Poco C++ Libraries v1.3.2 cross-built for ARM9 successfully. I am a very happy customer, and the price is right (thanks for your open source contribution).
Now I am upgrading to v1.3.3p1 so I can benefit from the general improvements, and the new support for controlling the thread stack size.
My first attempts to build are failing in include/Poco/Data/MySQL/Binder.h because mysql.h is not found. I am not using MySQL, so that is to be expected.
I am experimenting with trimming the Makefile to try to eliminate this build step, but I am curious what the recommended method is to exclude MySQL dependency from the build.
