在执行cmake打印命令之前 [英] Making cmake print commands before executing

问题描述

我正在开发一个用cmake在linux上构建的大型C ++项目。 Cmake运行良好，在模块和应用程序的树中生成一个Makefile的一部分。运行gnu make会导致链接器错误。在运行它们之前，如何让打印输出确切的命令？

I'm working on a large C++ project built with cmake on linux. Cmake runs okay, producing a horde of Makefiles in the tree of modules and applications. Running gnu make leads to linker errors. How can I get make to print out the exact commands before running them?

-d选项不打印命令，但大量的信息没有帮助。

The -d option does not print the commands, but plenty of information that hasn't been helpful.

-n选项打印所有命令，但不运行它们，所以我不能确定是什么麻烦。从make -n检查stdout，我没有看到任何相关的命令。我怀疑一些命令根据早期命令的结果而改变，而Makefile的层次结构使我们很难判断到底发生了什么。

The -n option prints all the commands, but does not run them, so I can't tell were exactly the trouble is. Examining the stdout from make -n, I don't see any commands that are relevant. I suspect some commands change depending on the results of earlier commands, and the hierarchy of Makefiles makes it difficult to tell what's really going on.

我没有看到任何其他

推荐答案

相当确定这会有效：

make VERBOSE=1

set(CMAKE_VERBOSE_MAKEFILE on)

这在 CMake常见问题。
