Making make print commands before executing when NOT using CMake
MakefileMakefile Problem Overview
I see that this is the same question as
https://stackoverflow.com/questions/4808303/making-make-print-commands-before-executing
But that answer doesn't work for me. I'm guessing that answer only works with cmake. What options work without cmake?
Note tried these
make VERBOSE=1 target
make target VERBOSE=1
VERBOSE=1 make target
make V=1 target
make target V=1
V=1 make target
make -V target
make -v target
none of them worked.
make -v returns

Makefile Solutions
Solution 1 - Makefile
By default, make
does print every command before executing it. This printing can be suppressed by one of the following mechanisms:
- on a case-by-case basis, by adding
@
at the beginning of the command - globally, by adding the .SILENT built-in target.
- somewhere along the make process, by invoking sub-make(s) with one of the flags
-s
,--silent
or--quiet
, as in$(MAKE) --silent -C someDir
, for example. From that moment on, command echoing is suppressed in the sub-make.
If your makefile does not print the commands, then it is probably using one of these three mechanisms, and you have to actually inspect the makefile(s) to figure out which.
As a workaround to avoid these echo-suppressing mechanisms, you could re-define the shell to be used to use a debug mode, for example like make SHELL="/bin/bash -x" target
. Other shells have similar options. With that approach, it is not make
printing the commands, but the shell itself.
If you use the flag -n
or --just-print
, the echo-suppressing mechanisms will be ignored and you will always see all commands that make
thinks should be executed -- but they are not actually executed, just printed. That might be a good way to figure out what you can actually expect to see.
The VERBOSE
variable has no standard meaning for make
, but only if your makefile interprets it.
Solution 2 - Makefile
For my version of make, I found BOTH paramters -n
and -d
helped.

-d Print lots of debugging information.
-n, --just-print, --dry-run, --recon
Don't actually run any commands; just print them.
When a bunch of makefile fragments are included, the line numbers don't make sense without this key debug flag.
CreateProcess(....exe,...)
Reading makefile `../../../../build/Makefile.options' (search path) (don't care) (no ~ expansion)...
Makefile:361: Extraneous text after `else' directive
Makefile:368: Extraneous text after `else' directive
Makefile:368: *** only one `else' per conditional. Stop.
Solution 3 - Makefile
I think this is what you want: make MAKE_VERBOSE=1 target
Solution 4 - Makefile
in my case i was able to suppress commands in output by setting up below variable in top my make file
# Use `make V=1` to print commands.
$(V).SILENT:
add the above line in top of you make file and when you call any target it wont print
Before :
muhasan@admins-MacBook-Pro fx.identitymanagement % make dockerstatus
cd identity.API/ && docker-compose ps
