Re: Break or exit out of user defined procedure

[Rakesh Sharma]

Hi TP ,


You can make use of the $(if ...) construct of GNU make for this scenario.


$(if $(call strip,$(filter $(1),$(PACKAGES_ALL))),true_portion,false_portion)


The true portion you already noted as a warning funtion.


And in case the false portion of the $(if ...) clause is too big and hampers 
maintainability of the

code, you factor out into another user-defined macro, and have that macro 
called up in the false portion

in the false portion.


For more info, you can check the manual out:

Thanks,

Rakesh

Subject: Break or exit out of user defined procedure

Hi,


Is it possible to exit a user defined procedure with something like this?


define inner-generic-package

ifneq ($(call strip,$(filter $(1),$(PACKAGES_ALL))),)
$$(warning Package '$(1)' defined a second time in '$(pkgdir)'; \
   previous definition was in '$$($(2)_PKGDIR)')
*return*
endif

<do alot of things>
endef




thanks,

TP
