Cannot call bash function inside makefile

问题

I have an impression that I can call bash function inside GNU makefile, but seems wrong. Here is a simple test, I have this function defined:

>type lsc
lsc is a function
lsc () 
{ 
    ls --color=auto --color=tty
}

Here is my Makefile:

>cat Makefile
all:
    lsc

Here is what I get in running make:

>make
lsc
make: lsc: Command not found
make: *** [all] Error 127

Is my impression wrong? Or is there any env setup issue? I can run "lsc" at the command line.

You cannot call bash functions or aliases in a Makefile, only binaries and scripts. What you can do however, is calling an interactive bash and instruct it to call your function or alias:

all:
    bash -i -c lsc

if lsc is defined in your .bashrc, for example.

Use $* in your BASH script:

functions.sh

_my_function() {
  echo $1
}

# Allows to call a function based on arguments passed to the script
$*

Makefile

test:
    ./functions.sh _my_function "hello!"

Running example:

$ make test
./functions.sh _my_function "hello!"
hello!

Did you export your function with "export -f"?

Is bash the shell of your Makefile, or is is sh?

回答4:

You can import all shell scripts functions from a shell file if you use this from the question How do I write the 'cd' command in a makefile?

.ONESHELL: my_target

my_target: dependency
    . ./shell_script.sh
    my_imported_shell_function "String Parameter"

If you like, you can also even do not use the .ONESHELL thing and do it all in one line just by using a colon ; right after the importing the shell script:

my_target: dependency
    . ./shell_script.sh; my_imported_shell_function "String Parameter"
