c++ - 运行 Qt hello world 时进程退出代码 0xC0000135

Question

这是我的main.cpp代码:

#include <iostream>
#include <QtWidgets/QApplication>
#include <QtWidgets/QPushButton>

using namespace std;

int main(int argc, char *argv[]) {
    QApplication application(argc, argv);
    QPushButton button("Hello, world!");
    button.show();
    return application.exec();
}

在 CLion IDE(最新版本)中运行它会出现以下错误:

Process finished with exit code -1073741515 (0xC0000135)

这是我的CMakeLists.txt:

cmake_minimum_required(VERSION 3.13)
project(simple_interpreter)

set(CMAKE_CXX_STANDARD 14)

if (WIN32)
    set(CMAKE_EXE_LINKER_FLAGS "-static")
endif ()
set(ENV{PATH} "C:/Qt/5.14.2/mingw73_64/bin") # As suggested in https://stackoverflow.com/questions/44739411
set(Qt5_DIR "C:/Qt/5.14.2/mingw73_64/lib/cmake/Qt5")
find_package(Qt5 REQUIRED COMPONENTS Core Widgets Gui)

add_executable(simple_interpreter main.cpp)

target_link_libraries(simple_interpreter Qt5::Core Qt5::Widgets Qt5::Gui)

来自 CMake documentation对于设置(ENV ...):

This command affects only the current CMake process, not the process from which CMake was called, nor the system environment at large, nor the environment of subsequent build or test processes.

因此，这不会在 CLion 环境中设置 PATH 环境变量。您应该尝试将路径 C:/Qt/5.14.2/mingw73_64/bin 附加到 Windows 计算机上系统环境变量中的 Path 变量。然后，请务必重新启动 CLion，以便应用 Path 变量更新。
