Description

The compiler gives a couple of warnings when building an Open C application to the GCCE (device) or WINSCW (emulator) target.

Compilation with GCCE build:

warning: command line option "-Wno-ctor-dtor-privacy" is valid for C++/ObjC++ but not for C

Linker warnings with WINSCW build:

warning: Multiply defined section for several functions.

Solution

These types of warnings can typically be ignored for GCCE/WINSCW builds. They are expected to be addressed in the next Open C release.

Warnings about the -Wno-ctor-dtor-privacy option can be disabled by modifying the \epoc32\tools\compilation_config\gcce.mk file. See How to use GCCE and Open C for more information.
