Re: Error when cross-compiling for ARM
Date: Mon, 09 May 2005 12:25:03 +0200
Its appears there are no "explicit" conversion operator.
Without the 112 line code, i don't know what conversion needed.
Its appear to need some code as:
const_cast< TYPE >( VARIABLE )
dynamic_cast< TYPE >( VARIABLE )
Or in C style cast as:
( TYPE ) VARIABLE
Or, some flag in cross-compiler to relax the ANSI C++ restriction.
Hope this helps.
