Module: sip-router Branch: master Commit: 0b2d2c6e99dac2bd171f1c24bfa6f285f6539273 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=0b2d2c6… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Wed Mar 10 17:30:39 2010 +0100 make: fix CPU reset in some conditions In some cases like trying to build a package with debug config (e.g. make cfg mode=debug; .... ; make deb), the CPU make variable was reset resulting in a build failure. This happens because in the debug config CPU is not set and hence is saved as empty. Trying to build a package will start a sub-make which will try to re-do the config without debugging (make cfg), but the CPU variable with and empty value will be inherited from the environment and thus the CPU?=something lines won't have any effect. The fix replaces CPU?=something with $(call set_if_empty,CPU,something) This works around having an empty CPU in the environment.
