Re: shell functions from env not available in make?

[gk]

I have just found the answer to the problem:
export -f function_name

The confusing thing is that 'set' command shows the function as a 'shell variable' in subshells, even without the export command.
But 'env' command does not show the function name until you use export -f
That is what make requires apparently.
My /bin/sh is a link to /bin/bash

Well now it can :-)
goo :
        @echo $$(xmsubdirs)
[greg@p3 test]$ make goo
foo.html.xm goo junkme moo.xm project

Here you're calling the shell without anything (Mind: $(xmsubdirs) is
empty!!), so it produces an empty line, and exits.

Now it isn't empty. It is a variable that bash tries to evaluate after expanding.

[greg@p3 test]$ make foo
XMLMAKE_BUILD_EXCLUDE_DIRS_RE='(^CVS)|(^trash)';: -c: line 1: syntax error near unexpected token `()'
XMLMAKE_BUILD_EXCLUDE_DIRS_RE='(^CVS)|(^trash)';: -c: line 1: `() { [ -z "" ] && set .;'

Cheers,
