A constant battle - I know that one. I myself consider V=1 great for debug perpose... as long as gcc's warnings are there if it's not specified, I don't enable it.

Actually we are parsing the gcc commandline to spot if you are using optflags and do some post build checks. (post-build-checks, check_gcc) Indeed there are actually several cases when lack of of usage of optflags was not observed due to silent build, such as in ninja, thin-provisioning tools and himeno - and those are just few cases which I noticed in last few days.

It's not (just) about optflags. Some broken configure/Makefiles are so broken that they heed exported variables (like what %configure expands to), but ignore argument variables, like %configure CFLAGS="%optflags -DFAEN" Which leads to very curious case that the macro is not set, but optflags is. That's when V=1 may come in handy to discover such. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
