    invalid conversion from (void *) to unsigned char

    Hello!

    I'm having trouble compiling my application. I was using gcc to compile the code, but now i have to compile it using g++...
    But when using g++, i always get the error "invalid conversion from void* to unsigned char"...

    I know, that the g++ compiler is ment for C++...

    I'f you require the code, I would be happy to post it.

    Is there a straight-forward solution for my problem?

    thanks

    Rok

    Post the smallest and simplest program that demonstrates the problem. Chances are you need to use a cast where C allows an implicit conversion from void*, but that is for a conversion from void* to a pointer type, not unsigned char.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
