Possibly a better workaround is a custom CC which prepends --no-as-needed onto gcc's command line:

BTW, it is possible now to select different configuration files entirely with the -conf=filename switch.

How is the PR and this addressing this issue? I might be missing something because I don't see the relation :-/

It's a step towards implementing comment #16

OK, there was still one problem with that approach, but I guess, fair enough.

Here's my evil plan:

Add a switch -confsection=sectionname which will cause [sectionname] in the config file to be parsed. There can be multiple such switches and sections, they'll be parsed in lexical order.

Note that:

    DFLAGS += string

can be handled without adding new features with:

    DFLAGS = %DFLAGS% string

The current way the config file is read twice wreaks havoc with the order in which sections are processed and things like appending to existing environment variables. This all has to be redone, but I'd like a green light on it being an acceptable resolution of this bugzilla issue before investing the effort.

(Currently order of evaluation is undocumented.)

I decided not to have -version=identifier do this, because inevitably someone will have a problem with it and want another switch to be able to do them independently.

Calling it -confsection will place it next to the -conf switch in the documentation, making the connection easily discoverable.

Will -confsection=debug be automatically added when -debug is specified? If yes (and there will be no more -llib flags automatically added at a certain place hardcoded in dmd), then I think this solves the problem at hand.

For cross-compiling it might be useful to also automatically enable other predefined sections, similar to -version, like linux, x86_64, etc., which is what I think Marting was suggesting. But that would be an extra feature.

No. You'll have to add -confsection=debug to have a [debug] section parsed. We can always add such a feature later, but it would be very hard to subtract it if it turns out to not be right.

I don't see any reason to add more.

I'd rather do without such, preferring to keep things simple and easy to explain.
