bizarre VC10 linker error

hey all, I just installed VC 2010 Premium Beta2 on my system and I migrated my old vc9 projects to it... everything seemed ok at first...

what's strange is that no matter what I compile I get the following error message:

1> Microsoft (R) Incremental Linker Version 6.00.8447

1> Copyright (C) Microsoft Corp 1992-1998. All rights reserved.

1>

1>  ■/

1>LINK : warning LNK4044: unrecognized option "ERRORREPORT:PROMPT"; ignored

1>LINK : fatal error LNK1181: cannot open input file " ■/.obj"

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

the warning about errorreport is a little annoying but non-fatal... annoying because no matter which errorreport setting I choose, the warning stays... however the LNK1181 is fatal and even more frustrating because it seems to have no detectable cause.

my input list contains no .obj files, only various .lib files... furthermore, there is that strange block-like special ascii character in the name which I've certainly never typed anywhere. initially when this showed up I thought it must be some artifact of the vc9 to vc10 migration... and after spending 2 hours looking all over for the cause, it occurred to me to test whether or not it occurs with brand new projects... well sure enough it does!!

I create a BRAND NEW project... involving no migration, nada... just a brand new win32 project with the default afx files and so forth... I d开发者_如何学编程on't change any default setting and it gets this exact same linker error!

I hope somebody here can shed some light because this is very mysterious... at the moment the only other diagnostic method I can think of is to try to create a new workspace and add a new project to that and see if that works... ok just tried that and no dice... problem still persists.

anybody have some advice or seen this before?

You have an old copy of your pre-processor or linker (cl.exe, link.exe) in your system path.
