Hello,
I am a new beginner of gnu Make. in some cases, I fell that it will help
if Make can print the
executing shell command even suppressed, for example, to identify
problem more easy.
Since it seems that Make doesn't have this flag, I tried to change code.
the code diff is in below and happy to hear what your idea.
Thanks!
