问题描述
我使用CMake与GNU Make，并希望看到所有的命令（例如如何执行编译器，所有的标志等）。
I use CMake with GNU Make and would like to see all commands exactly (for example how the compiler is executed, all the flags etc.).
GNU make有 - debug ，但它似乎并没有帮助有任何其他选项？
GNU make has --debug, but it does not seem to be that helpful are there any other options? Does CMake provide additional flags in the generated Makefile for debugging purpose?
推荐答案
当你运行make时，添加 VERBOSE = 1 以查看完整的命令输出。例如：
When you run make, add VERBOSE=1 to see the full command output. For example:
cmake .
make VERBOSE=1
或者您可以添加 -DCMAKE_VERBOSE_MAKEFILE：
Or you can add -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON to the cmake command for permanent verbose command output from the generated Makefiles.
cmake -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON .
make
要减少一些可能不那么有趣的输出，您可能想使用以下选项。选项 CMAKE_RULE_MESSAGES = OFF 删除像 [33％] Building C object ... 这样的行，而 print-directory 告诉make不打印当前目录过滤出 make [1]：输入目录和 make [1]：离开目录。
To reduce some possibly less-interesting output you might like to use the following options. The option CMAKE_RULE_MESSAGES=OFF removes lines like [ 33%] Building C object..., while --no-print-directory tells make to not print out the current directory filtering out lines like make[1]: Entering directory and make[1]: Leaving directory.
cmake -DCMAKE_RULE_MESSAGES:BOOL=OFF -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON .
make --no-print-directory
