Call to unavailable function 'system': not available on iOS

Question

I'm new to cocos2d-x and while compiling my project I get this error.

Call to unavailable function 'system': not available on iOS

I see this call is no longer applicable but, what can I use to replace it? Any insight would be appreciated!

bool FileUtils::removeDirectory(const std::string& path)
{
#if !defined(CC_TARGET_OS_TVOS)
    std::string command = "rm -r ";
    // Path may include space.
    command += "\"" + path + "\"";
    if (system(command.c_str()) >= 0) /*System Call Error/Not Availible*/
        return true;
    else
        return false;
 #else
    return false;
#endif
}

I have not confirmed this, but you might try something like the following:

//  This is ugly, but it should work
if (fork() == 0)
{
    string fullpath = "\"" + _storagePath + "\"";
    string arg1 = "-r";
    char* args[] =
    {
        &arg1.at(0),
        &fullpath.at(0),
        nullptr,
    };
    const char* command = "rd";
    execvp(command, args);
}

system function is not available on iOS 11 Use this mean while until Oct 9 we can have new cocos2d-x 3.16

if (command.size() >= 0)

Answer 3

system function is not available on iOS 11, there is a accepted PR for the same issue.

Now we're using nftw instead of system. Update your source with v3 branch of cocos2d-x repo.
