.NET Forum / Languages / Managed C++ / May 2006Incremental Linking not working with /nod option
We have recently upgraded from VS2002 to VS2005 and I'm having a problem with the linker always performing a full link even though nothing has changed. In searching the newsgroups I found that I could add "/test" to the linker options and it would tell me why it was causing it to re-link (full link). This is what I get. Linking... LINK : file alignment: 512, section alignment: 4096 LINK : LINK options changed; performing full link LINK : performing full link It tells me that something changed in the link options, but it doesn't tell me what. The other problem is that nothing was changed. I can do two builds back to back and it will do a full re-link every time. After fighting this for a week, I finally found something. The problem is I don't know what to do about it. We are a Unicode MFC (static linked) app and use the unicows layer so we can run on 9x. Unicows layer requires the linker options "/nod:<various windows libs>" in order to work correctly. If I remove all the "/nod" linker options, the re-link is no longer done. If I make a small change, then incremental linking works. This is exactly what we need. But, I can't leave out the /nod options. Has anyone ran into this issue and/or does anyone have a solution to this? Thanks Scott Hi a) can you please run dumpbin /directives xxx.obj where xxx.obj is a typical object file of your project and tell us what you see. b) what are your linker options (you can find them in buildlog.htm) Marcus > We have recently upgraded from VS2002 to VS2005 and I'm having a problem > with the linker always performing a full link even though nothing has [quoted text clipped - 26 lines] > > Scott Thank you for your help.

Maybe you find another unicows.lib file that causes less problems. Do you use the one from the platform SDK?

You do not really need the unicows stuff in debug build, do you? David Wilkinson I would like to fix this if at all possible, but if not, this is a great work around. Thanks for sharing.
