The Trace Compiler is a tool that is attached +to the Symbian OS Build System. It is run before the actual C++ compiler. +The purpose of Trace Compiler is to generate the needed headers for Open System +Traces (OST) traces to compile. Trace Compiler is run when you normally compile +your component that has OST traces.
+When Trace Compiler is run and the project contains OST traces, +you should find the following text printed on the Console tab, +as in the following example for the HelloWorld component:
+ +perl C:/Symbian/9.3/S60_3rd_FP2/epoc32/tools/tracecompiler.pl WINSCW +******************* TRACECOMPILER STARTS ******************* +Building traces for component HelloWorld. Component UID: 0xEAAEC036. +******************* TRACECOMPILER ENDS *********************+ +
After Trace Compiler is run, the needed headers are generated to the traces +folder of your component. If you have OST traces in HelloWorld.cpp, +the header to be generated is HelloWorldTraces.h, which is included +from HelloWorld.cpp.
+Note: If you cannot find the following line or similar when compiling +your component, it might be that your SDK does not have Trace Compiler installed:
+ +perl C:/Symbian/9.3/S60_3rd_FP2/epoc32/tools/tracecompiler.pl WINSCW+ +
