LittleGPTracker

This is a fork of m-.-n's LGPT for Symbian (S60v3) devices. Built and tested on a Nokia E63 (S60v3 FP1).

At present, everything works - except the keyboard becomes unresponsive when audio is running. To be fixed.

Runtime dependencies

You need the Open C/C++ libraries installed; these come with the Qt installer, amongst other places. The separate SIS files are also available in the Open C/C++ plugin (see below).

Compile dependencies

You need:

• an S60 SDK matching your phone (v3, v3 FP1, v3 FP2) - these are not backwards compatible but somewhat forwards
• a suitable version of the GCCE compiler
• the Open C/C++ plug-in
• SDL-S60v3 from here: http://repo.or.cz/w/SDL.s60v3.git

Unfortunately the Nokia site with the SDKs and tools is now gone. Most of the necessary files can be found here: http://n8delight.blogspot.com.au/2014/05/for-developers-re-up-of-symbian.html I also found a copy of Open C/C++ on 4shared (look for s60_open_c_cpp_plug_in_v1_7_en). The Qt SDK 1.1.x includes compiler, SDK and plug-ins all together, which are suitable for FP2 and above. This can be found here: ftp://ftp.informatik.hu-berlin.de/pub/Mirrors/ftp.troll.no/QT/qtsdk/

To build:

• Install the SDK, which will add it to your PATH or give you a startup link to do so (QtSDK does this).
• Install the compiler, put its bin directory on your PATH
• Install Open C/C++ over the SDK
• cd SDL-s60v3\symbian; bldmake bldfiles; abld build gcce This installs the resulting files into the SDK tree (eek).
• cd LittleGPTracker\projects; make Assuming the platform is set to S60, this should give you lgpt.sis which you can install.

Notes

There is a "make run" target which will use runonphone.exe (available in the QtSDK, amongst other places). You need the App TRK installed and running on your phone.

I had to patch a few bits of the FP1 SDK to get the compiler to work! Notably, I had to replace macros defining va_list, va_start, va_end etc. using __builtin_va_{list,start,end}.

If you use a newer SDK than your phone you might get lucky, or you might not. The FP2/QtSDK built the project nicely, but it refused to run on my phone with "Feature not supported".

There's a debugger fdb in the FShell project at http://fshell.sf.net which can give you stack traces; use fdb -m e:\ to point it at lgpt.exe.map with all the symbols.
