64 bit compilation VC++ 2010 Pro

Hi WASY,

I have an existing 32 bit IFM module that works as intended on Windows XP 32 bit. Due to a recent upgrade in hardware I now need to compile the module for FEFLOW 64 bit using Windows 7 64 bit Enterprise. To do so I use Microsoft VC++ 2010 Professional. I have changed the neccesary settings/options/preferences so that the compiler is set to x64 in accordance with the pdf IFM example guide (which appears to very obsolete). I even created a new module in FEFLOW 64 bit so that I could simple copy-paste the code from the original module into the new source file (the part of the code written by me - not the code generated automatically by FEFLOW on module creation). 

This however does not work.

I get the following errors when compiling:

I can't seem to find a guide on how to set this up in VC++ 2010 allthough one is mentioned here http://www.feflow.info/html/help/default.htm?turl=HTMLDocuments%2Fmorehelp%2Fdocumentation.htm (can't seem to download it anywhere). Will I need the 2008 version to make this work?

Thanks in advance!

I managed to resolve some of the issues myself but I am left with the following errors:

Apparently the module will not register. I tried to remove the double slash and the doube quote in this string ""C:\Program Files\WASY\FEFLOW 6.0\\bin64\feflow60c.exe" in Properties->Build events->Post Build events (in VC++) but with no result.

Dear Søren,
Check if the dll has been succesfully created and - if yes - to manually register it in FEFLOW. The automatic registration of the plug-in is only a convenience feature that is run after the actual compiling step.
Alex

Thanks Alexander.

The dll is created but I get the following errormessage "Invalid registration procedure: "RegisterModule"!" in FEFLOW (both Classic and the new version) when trying to load the dll as a module. The problem occurs when compiling both 32 and 64 bit using VC++ 2010 and using the FEFLOW IFM template as described in the manual. Manual registration using the command prompt yields the same error.

I'm having the same issue in the same problem. Old 32bits VS2008 plugin, now trying to compile on VS2010 with Windows 7 64bits.

My DLL is built but I'm not able to register it even manually.

Cheers,

Eduardo

We have tracked down the problem now. Reason for the difficulties is a missing entry in the [i]Linker[/i] > [i]Input[/i] section in the [i]Configuration Properties[/i] of the VC++ 2010 project settings. For new plug-ins set up via the wizard in VC++ 2010, this will be fixed with the next FEFLOW patch 6.06. In the meanwhile and for existing projects, simply add the [i]Module Definition File[/i] manually as shown in the attached screenshot.

Thanks Peter!
