A simple hello world like dfl application takes 1.2mb. Upx does a

I couldn't find a way to get help on the numerous options in optlink,
and the help page at digitalmars doesn't list them either.
I've noticed around two times smaller exes when linked with
unilink. So
if you don't like packing you may try it:
ftp://ftp.styx.cabel.net/pub/UniLink/ulnb0319.zip
<ftp://ftp.styx.cabel.net/pub/UniLink/>
just make sure you configured it correctly (should be straightforward,
there are examples)
Thanks. Any idea if unilink works with libraries linked with optlink?
I get "Error: Invalid library file (3) 'some optlink.lib'"
For what it's worth any D2 app uses phobos.lib and obviously that
worked. Not that it was linked, library is a sort of a package with obj
files. Also check if this is in fact library it might very well be
renamed executable in which case 2 first bytes of file are 'MZ'.
It should work with both OMF (DMC, old MS VC++ etc.) and COFF (MinGW,
modern MS C++ etc.) libraries.
Tried a minimal sample using only phobos. Gave me another error:
Error: Unresolved external '__acrtused_con' referenced from 't.obj'
I downloaded the entire dm compiler and added snn.lib which solved the
problem.
Yes, I should have mentioned it. Btw snn.lib lives in dmd2\windows\lib
I'm still getting linker errors on the old file though.

No problem.

UniLink v1.07 [beta] (build 3.19)
Error: Invalid library file (3) 'c:\d\ext\dwin\lib\dfl.lib'
Hm.. you might try to link with just object files then. Still it's
weird, could be a bug in unilink.
If you inclined that this is the case, send sample obj and lib to
developers with some info ulink(at)styx.cabel.net
Judging by my experience, sending source code in addition to obj files
is appreciated.
