I'm trying to print bold text from the following Makefile
:
printf-bold-1:
@printf "normal text - \e[1mbold text\e[0m"
But, escape sequences are printed as-is, so when running make printf-bold-1
, I got :
normal text - \e[1mbold text\e[0m
Instead of expected :
normal text - bold text
It's weird because I can print bold text from my terminal : running directly command printf "normal text - \e[1mbold text\e[0m"
produces, as expected :
normal text - bold text
In the Makefile
, I tried to use @echo
or echo
instead of @printf
, or print \x1b
instead of \e
, but without success.
Here are some variables describing my environment (Linux with standard Gnome terminal), if that can help :
COLORTERM=gnome-terminal
TERM=xterm-256color
Note also that on some colleagues laptops (Mac), bold text is printed correctly.
What is the portable way, working on every environment, to print bold or colored text from a Makefile
rule?
