我在Qt Creator 4.5.2。中加载了一个C ++项目。

我有一个仅标头的库，以及一个测试该库的测试项目。测试项目具有清晰的main功能。

测试项目正确构建。当我从控制台运行生成的可执行文件时，它可以按预期运行，但是Qt Creator无法运行或调试测试项目，并出现以下错误：

/ usr / lib / x86_64-linux-gnu / Scrt1.o：-1：在函数'_start'：]中>

（。text + 0x20）：-1：错误：未定义对“ main”的引用：-1：错误：

collect2：错误：ld返回了1退出状态

我看过SO，发现的所有人都是忘记写主要功能的人，这不是我的情况。

这是怎么回事？我该如何解决？

我的主要功能很简单：

#include "test_math.h"
#include "test_engine.h"

/**
* @brief main
* @return
*/
int main() {

    std::cout << "GridCal++ tests" << std::endl;

    gce_test::sp_submatrix_test();

    //gce_test::sp_mat_test(makeA, makeb);

    gce_test::sp_submatrix_test();

    gce_test::graph_test();

    gce_test::test_engine_1();

    gce_test::test_engine_wei_min();

    gce_test::test_lynn_5bus();

    gce_test::state_stimation_test();

    gce_test::test_psse_file();

    gce_test::test_json();

    std::cout << "\n\nAll tests done." << std::endl;
    std::cout << "Press ENTER to exit." << std::endl;
    std::string line;
    std::getline(std::cin, line);

    return 0;
}
具有.pro的项目的main.cpp是：
