cmake编译出现Invoking "make -j12 -l12" failed错误

这个错误可能是由于你的系统中没有安装make工具导致的。请尝试在终端中运行以下命令安装make：

- 在 Debian/Ubuntu 系统中：sudo apt-get install make
- 在 Fedora/CentOS/RHEL 系统中：sudo dnf install make
- 在 MacOS 中：brew install make

如果已经安装了make，那么可能是你的并行编译线程数太多导致的。你可以尝试减少并行编译线程的数量，比如将 -j12 改为 -j4。

cmake --build . -- -j12

cmake --build . -- -j12命令的作用是使用CMake构建项目并指定并行编译的线程数为12[^1]。

具体步骤如下：

1. 首先，在命令行中进入到项目的build文件夹中，可以使用cd命令切换到该目录下。

2. 接着，使用cmake --build . -- -j12命令执行构建操作。其中，"."表示当前目录，"-j12"表示并行编译的线程数为12。

这个命令会自动调用适合的构建工具来编译项目，例如make或者ninja。通过指定并行编译的线程数，可以加快编译过程的速度。

需要注意的是，命令中的"--"是用来分隔cmake命令和构建工具命令的，确保构建工具能够正确解析后续的参数。

Invoking "make -j2 -l2" failed

The error message "Invoking 'make -j2 -l2' failed" typically indicates that the make command failed to execute properly. This could be due to a variety of reasons, such as missing dependencies, incorrect permissions, or syntax errors in the makefile.

To troubleshoot this issue, you can try the following steps:

1. Check the error message for any specific clues about what went wrong. Look for error codes, file paths, or other information that might help diagnose the problem.

2. Verify that all necessary dependencies are installed and up to date. This may involve installing additional packages or libraries, depending on the project requirements.

3. Ensure that you have the proper permissions to run make commands. If you are working on a shared server or within a virtual environment, you may need to contact your system administrator to grant the necessary permissions.

4. Double-check the syntax of the makefile to ensure that it is free of errors. Makefiles can be complex, so it's important to review them carefully for typos or other mistakes.

5. Consider using a different build tool, such as CMake or SCons, if make continues to fail. These tools may offer a more robust and reliable alternative for building your project.

If none of these steps resolve the issue, you may need to seek additional help from the project's documentation or support forums.
