As one of the co authors, I’m really exited to announce that Quick Recipes on Symbian OS has just been released by Symbian Press. According to the official literature,

The book tells you how to start developing C++ applications for Symbian smartphones from scratch and includes recipes that are divided by technology, including graphics, multimedia, location-based services, networking and messaging. Each recipe explains the length of time needed to implement it, and its difficulty level. The task is then explained in detail, and provides snippets of example code. The full sample code is provided for future reference and for use as a starting point in your own projects.

Get a copy from Amazon here, while its hot baby While at it, have a look at the book’s WiKi page, where you’ll find the recepies(code examples) and the errata.

Happy coding!

The Carbide.c++ team at Nokia has just published a series of articles that explains the Carbide.c++ build system in-depth and how to get the most out of it. A recommended read for all developing software with Carbide.c++.

• Building a better build system-Part 1: Introduces improvements done in Carbide.c++ 1.3 for detecting MMP file changes and dependency tracking using the compiler
• Building a better build system - Part 2 Concurrent builds: Explains using parallel compilation using Carbide.c++
• Building a better build system - Part 3 Eclipse incremental builder: Explains the benefit of using the Eclipse incremental builder. Note that there’s a small issue/bug with the incremental builder if you are using multiple SDKs, it won’t automatically detect that you’ve switched SDKs and hence fail to build the new target, even if its not built. Only applicable where you have a project that’s been created/imported to use more than a single SDK
• Building a better build system - Part 4 Benchmarking: Puts everything into perspectiva and summerizes by listing the pros/cons of using different build options and how that results into build speed

Happy coding!

A colleague of mine recently popped down at my desk, asking me if there was an easy way to find the macros defined for a Symbian project build configuration. Given that a macro can originate form different places, its not always a easy guess. Of course you can look at the usual suspects, like the HRH file for the platform (\epoc32\include\variant\Symbian_OS_*.hrh) and the MMP file itself for the MACRO directive, but it won’t give you the full list, since the Symbian tool chain will insert its own on top. So how do you get it? Enter Carbide.c++ build configurations.

Ok here’s a bog standard piece of Symbian C++. What’s wrong? Hint, its all in the status…

void CConnectionProgressObserver::RunL()
  {
  if (KErrNone == iStatus.Int())
    {
    iConnection.ProgressNotification(iProgressBuf, iStatus);
    SetActive();
    }
  // OnProgressNotificitionL is
  // a callback (void)(TNifProgress, TInt)
  iNotify->OnProgressNotificitionL(iProgressBuf(), iStatus.Int());
  }

Still didn’t get it? Read on…
