link error

[jmloriot]

Bonjour Fortran fellows,

My projects used to link and work fine. Then suddenly I get the following error.

So I go to "project properties", change the default libs, try again, most of the times it does not work, but sometimes it links fine, but only one time.

My other projects with exactly the same parameters do link fine.

Thanks in advance for your help

You are linking against both the Quick-win support libraries and the console-application support libraries.

You need to choose one or the other, and that depends (of course) on what your application is doing.

Then, do a complete rebuild of your application.

I suggest a full rebuild because the library-type is encoded in the object file.   If you have an "old" object file around requesting the wrong library, then you'll be back in this same situation.

                   I hope this helps --

Thanks a lot, now it makes sense for me

I have both Quick-win and Console-application projects in the same solution and they use the same  subroutines ; it is not straightforward to separate them, but I know what I have to work on.

Thanks again

Well ... this sounds interesting, and frankly I hadn't thought of this configuration.

Another thing you can do is in the Quickwin project, add ifconsol.lib to the list of "ignore specific default" libraries on the property page Linker -> Input

And, in the console project, add ifqwin.lib to the list of "ignored" libraries.

Now, it won't matter how you've built the objects shared by both projects.

Thank you very much for your help.

Both the Quick-win and the Console-application were using the same intermediate directory.

Using 2 different intermediate directories did fix the problem.
