I’ve tried GCCE version 4 before for building Symbian software, but have been somewhat put off by all the warnings it produces, mostly due to incompatibilities with the header files in the existing S60 SDKs. Well, I finally managed to get a working S60 application built with GCCE 4 without any warnings. Mind you, this was just one application, and not built with the full Symbian toolchain, but still.

Symbian’s ABLD build system tends to produce a lot of output, especially when run with the verbose flag (-v), as I like to do to see the compiler invocations. Also, ABLD likes to run to “completion” despite individual build steps failing. The end result is that it takes some effort to look for the errors and warnings in the output.

The SDK API Plug-in package for S60 SDKs has quite a few interesting APIs, such as the Browser Launcher API and the New File Service Client API.
