Linux中C++获取源文件目录

#include <iostream>
#include <libgen.h>

int main() {
    char path[PATH_MAX];
    realpath(__FILE__, path);
    std::cout << "源文件目录：" << dirname(path) << std::endl;
    return 0;
}

#include <iostream>
#include <filesystem>

int main() {
    std::filesystem::path path = std::filesystem::current_path();
    std::cout << "源文件目录：" << path << std::endl;
    return 0;
}
