编译 QTermWidget [英] Compiling QTermWidget

问题描述

我尝试编译这个自定义 QT 小部件以提供一个可以嵌入到我的应用程序中的终端. 我已经编译/安装了我需要的程序构建工具在 Cmake 完成之前，但 make 步骤抛出了谷歌没有太大帮助的错误:

I've tried to compile this custom QT widget to provide a terminal that I can embed into my application. I've compiled/installed the build tools for the program that I needed before Cmake would complete, but the make step is throwing errors that google hasn't been too helpful on:

有没有人有解决这个问题的方法?

Does anyone have a solution to this problem?

作为扩展，如何有效地包含自定义小部件以便在 QT Creator 中可用?

And as an extension, how exactly does one effectively include a custom widget as to be usable in QT Creator?

推荐答案

http://pubs.opengroup.org/onlinepubs/7908799/xsh/utmpx.h.html

看起来它在 utmpx.h 的股票版本中不包含 ut_name.

It looks like it doesn't include ut_name in the stock version of utmpx.h.

如果你看看这个版本:

https://code.woboq.org/kde/include/bits/utmp.h.html

他们在那里有一个向后兼容性黑客":

They have a "backwards compatibility hack" in there:

87  /* Backwards compatibility hacks.  */
88  #define ut_name     ut_user

您可能想要升级包含该标头的库.或者只是在您的代码中插入 #define.作为一个优秀的 github 公民，如果它有效，你应该做一个拉取请求和/或提交一个关于它的问题，这样下一个使用该库的人就不会遇到同样的问题.

You may want to upgrade that library that includes that header. Or just insert that #define in your code. And as a good github citizen, if it works, you should do a pull request and/or submit an issue about it so that the next person using that library doesn't run into the same issue.
