If I create the below Makefile:
#----------------------------------------------------------------------
default: proxy
@echo "Done building module subdirectories"
proxy: ForceMe
@echo making: $@
ForceMe:
#----------------------------------------------------------------------
then do:
marcs@alive:/tmp/tm$ touch proxy ; make
Done building module subdirectories
marcs@alive:/tmp/tm$ touch proxy ; sleep 1 ; make
making: proxy
Done building module subdirectories
It doesn't execute the proxy target unless I make it pause in
between. Any workarounds other than changing the target to proxy_targ
or something like that?
Aha. The below patch fixes it for me. Anyone agree with the patch?
