In an attempt to get MiniD to compile under the new GDC 0.20, I found out about the -fonly flag from DSSS.  It's what DSSS uses to "resolve circular dependencies."

Here's the thing -- I have no idea what this flag does.  I can't find documentation for it anywhere.  I did "gdc -v --help" and -fonly doesn't appear anywhere in the output.

This is the only way I have ever heard of anyone successfully compiling MiniD using GDC short of combining the two files which mutually import one another.

All I can get it to do is to give me an error.  Even in the simplest possible case:

gdc -fonly=test.d

I get the error:

Assertion failed: an_output_module, file
../../gcc-3.4.2-20040916-1/gcc/d/d-lang
.cc, line 907

This application has requested the Runtime to terminate it in an unusual
way.

Did this appear in 0.20?  Am I using it wrong?

-fonly is only documented in that it's used from the gdmd wrapper.

Basically: gdc -c <EVERY .d file> <-fonly=the .d file you want to compile>

Otherwise it will only parse one at a time. It's ... weird.

Ahh, sweet, now it works.  Didn't think to put the -fonly file in the regular file list as well.  Though that bug with that simple test case should probably be reported..
