Qt创建器启动调试器失败

Qt Creator failed to start Debugger

本文关键字：调试器 失败 启动 创建 Qt      更新时间：2023-10-16

Qt c++项目在Qt Creator 3.4.1下成功构建。但是当我无法启动调试器时。输出:

调试开始

调试失败

调试完成

调试器从未真正启动。

终端输出:

当我安装gdb的源代码时，我没有附加——with-python选项。我在谷歌上搜索了一下，有人确实使用了这个选项，但没有任何结果。

终端的输出暴露了两个问题:

  1. ImportError: No module named importlib导致Python中不支持的库。所以就像@Amartel说的那样，安装新版本的Python(大于2.7)。但是在我的情况下，gdb需要用——with- Python配置选项重建，使gdb使用新版本的Python。

  2. Python Exception <type 'exceptions.ImportError'> No module named gdb: /usr/local/bin/gdb'可通过拷贝gdb_src_dir/gdb/data-directory/python/gdb目录下的文件到/usr/local/share/gdb来解决。注意:我的gdb安装在/usr/local/bin下。

最后，调试器工作正常。

然而，我没有得到问题2的原因。有人能解释吗?
