fatal error LNK1136: invalid or corrupt file

Hey there, I'm getting messages like this

fatal error LNK1136: invalid or corrupt file

When trying to create a DLL in Visual C++ 6.0. Its complaining about .h files I'm including and if I don't include them I get unresolved symbol messages. Is there a special way to include files when creating DLLs? If not is there some setting I'm missing?

You chould shut down the program what loaded the dll before linking. While dll is loaded in memory, you can't edit/write it while linking. John Fill

It is a dll I'm creating, how can it be loaded into memory, it doesn't even exist yet

 

[Cagliostro]

Have you succesfully compiled it once? Have you try to debug it? There exists many ways it to stay in memory with doing something or nothing. John Fill

THE DLL DOES NOT EXIST!

In this case, maybe some cpp libraries are corruped. You must change them. LookUp which one is corruped and changhe. You could accidentally delete one of them or it could been since instalation of VisualStudio. John Fill

Like JohnFill said, sometimes, for inexplicable reasons, some of the standard header files will get corrupted. I've had to reload a header from the CD more than once because it got badly mangled.

 

[joeGrammar]

So you guys don't think this is a dll creation specific problem?

 

[joeGrammar]

Also how would I check for a header file to be corrupt?

 

[Cagliostro]

In the header file is corrupt you will get compiller message. Simply it will not compille. Linker errors are because of linking compilled files to exe,lib,dll,ocx...
The compiled files are usualy obj's. Try to see which obj or lib the linker can't link to your dll. John Fill

When I've had problems with corrupt header files, I opened them up and saw a ton of garbage - they didn't even look like header files.

Once I have accedently put my.dll instead of my.lib in the line of libraries to link with my programm and I have this error.
Be sure you did not make this mistake.
