Using Cmake with GNU Make: How can I see the exact commands?

Question

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 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?

try -v

(verbose)

Answer 2

When you run make, add VERBOSE=1 to see the full command output. For example:

cmake .
make VERBOSE=1

Or you can add -DCMAKE_VERBOSE_MAKEFILE=ON to the cmake command for permanent verbose command output from the generated Makefiles.

cmake -DCMAKE_VERBOSE_MAKEFILE=ON .
make

Answer 3

If you use the CMake GUI then swap to the advanced view and then the option is called CMAKE_VERBOSE_MAKEFILE.
