Windows 中出现“找不到标识符”错误，但 Mac 中没有

Question

I have this function that works fine in my mac when when I try to compile my program in Windows I get an error:

std::string myMainWindow::getPlansPath() {
    char cwd[1024];
    if (getcwd(cwd, sizeof(cwd)) != NULL) {
        printf("Current working dir: %s\n", cwd);
    } else {
        perror("getcwd() error");
    }

    std::string path = std::string(cwd) + std::string("/myfolder");

    return path;
}

Error:

C:\path\to\project\gui\myMainWindow.cxx(876): error C3861: 'getcwd': identifier not found
ninja: build stopped: subcommand failed.

What can it be?

UPDATE:

I end up using QDir::currentPath() which was exactly what I wanted.

Answer 1

getcwd is an UNIX specific function, it does not exist in Windows, the fact that it belongs to the <unistd.h> library is a good hint to that. A possible solution would be to use _getcwd though I'm not familiar with it's use, I gather by the MSDN page, it's more or less the same.

Answer 2

You'll have to use _getcwd or _wgetcwd in the <direct.h> or <wchar.h> headers on Windows .
