    invalid conversion from (void *) to unsigned char


    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?

    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.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. 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.
