c++ - CMake 引用我在 ~/bin 中创建的随机 shell 脚本（即使在我删除它之后）？

问题描述

在 Ubuntu（20.04，Cinnamon 桌面）中，我创建了一个基本的 shell 脚本来从命令行运行具有以下内容的 .desktop 文件：

#!/bin/sh
$(grep '^Exec' $1 | tail -1 | sed 's/^Exec=//' | sed 's/%.//' | sed 's/^"//g' | sed 's/" *$//g') &

然后运行chmod +x以便能够将其作为命令执行。现在，每当我使用 时cmake --build，它都会包含这个文件的内容——即使在我删除了有问题的脚本并完全重新启动之后。这是我最近尝试 cmake 的输出：

alexander@alexander-Inspiron-7559:~/Documents/Code/CPP/SDLProject/bin$ cmake --build .
CMake Error: The current CMakeCache.txt directory /home/alexander/Documents/Code/CPP/SDLProject/bin/CMakeCache.txt is different than the directory /home/alexander/Documents/Code/CPP/OGRE-Project-1/bin where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt

解决方案

查看您创建然后删除的脚本是否在 CMakeCache.txt 文件中被引用。如果是，则删除/删除引用。

我记得 Cmake 是一个“源目录外”构建工具（您创建一个新的空构建目录，然后引用您的源目录）。当它开始构建时，它会为文件生成一个缓存/列表——参见“CMakeCache.txt”——以在编译时帮助解决依赖关系。

删除“CMakeCache.txt”文件也可能对您有用，因为它将由 cmake 重新生成。
