I'd agree with Kevin's suggestion, for a simple C++ sample application that only performs a simple read, you shouldn't need the config classes, try to do in C++ something simple as the java sample you just posted here.
As for downloads, you only need to download the DAS distribution, that will contain all the SDO and other dependencies inside the zip. For the new people, I'd recommend using the stable M2 distributions, although I think SDO and DAS trunk code are stable and compiling fine. -- Luciano Resende http://people.apache.org/~lresende On 2/8/07, Adriano Crestani <[EMAIL PROTECTED]> wrote:
