Please always CC the mailing list rather than replying to individuals
directly.
When reporting that a command fails always include the exact command
line you invoked and the error messages (plus maybe a few lines of
output for context).
Your new error is the syntax above: the "@" is a special character for
make and cannot be inside the parenthesis. The recipe line must be:
+@(cd $(RELEASE_TARGET); $(MAKE) release -j10)
However, the parentheses here are redundant: make always runs every
command in a subshell so there's no need for parentheses. Also, you
should use "&&" between the commands so that if the first one (the "cd")
fails, make won't try to run the sub-make. And finally, the "+", while
it won't hurt, is not needed because you are using the variable $(MAKE)
in the recipe so make already knows it's a submake:
@cd $(RELEASE_TARGET) && $(MAKE) release -j10
However, it's not a good idea to add an explicit "-j10" here. You are
invoking "make build_release" with the "-j10" argument so it should not
be here. This should just be:
@cd $(RELEASE_TARGET) && $(MAKE)
and that's all.
