NCURSES library linking in C++

wood@addanc · 07-06-2007, 06:28 AM

If I specify -lncurses I get the libncurses.so shared library which causes a segment fault when linked with my C++ application. If I specify -lncurses++ there isn't an equivalent libncurses++.so shared library on my openSuSE 10.2 distro. If I specify -static -lcurses++ to get the libncurses++.a static library (which does exists), but I find that one of the other libraries doesn't have a static version!

Is the omission of a libcurses.so shared library a distro problem?

Has anybody out there got a solution to this C++ linking problem?

Can you post a complete, compilable, tiny program which gives you the segmentation fault that you talked about?

Duff piece of wrapper code:

Code:

void Console::clear()
{
    clear();         // Intending to call ncurses clear() function. But just calls

    move(0, 0);
}

Code:

void Console::clear()
{
    ::clear();         // Intending to call ncurses clear() function.
    move(0, 0);
}

{
    clear();         // Intending to call ncurses clear() function, but just calls
                     // Console::clear() recursively until segment fault.
    move(0, 0);
}

Better:

Code:

void Console::clear()
{
    ::clear();         // Now global namespace ncurses clear() function called.
    move(0, 0);
}

Better choice of names would have helped.

To beat it to death, just so you're not left hanging:

Am I correct in assuming that you've solved your problem?

Yes
