Topic: Unknown build error

[shers]

Hi,

I am trying to migrate my application developed for ACAD 2012 to ACAD 2013. I have reference the dlls like accoremdg.dll, acdbmgd.dll and acmgd.dll from the corresponding folder. However, I get 1 error and 3 warnings as below.

Warnings:

1 Warning   1   There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "accoremgd", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

2. Warning   2   There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "acdbmgd", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

3. Warning   3   There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "acmgd", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

Error:

4. Unknown build error, 'Could not load type 'Autodesk.AutoCAD.Runtime.CommandClassAttribute' from assembly 'Acmgd, Version=19.0.0.0, Culture=neutral, PublicKeyToken=null'

Please help.

Thanks

What are your build settings; Debug + Any CPU?

Which ObjectARX SDK are you loading the assembly references from?

[shers]

Build settings is Release + Any CPU. However, I tried with x86 and x64. But with x64, the warnings vanish and the error remains.

I load the dlls from AutoCAD application folder.

Thanks

have you tried a clean rebuild?

[shers]

yes

[Jeff H]

ahh missed the 2012 to 2013 part
CommandClassAttribute is in AcCoreMgd.dll in 2013

Yes, I have referenced that as well.

If I had to guess I'd say you're using a 64 bit dll in a 32 bit machine.

What are your computer specs ?
Which version of Visual Studio ?
Which version of dot.net ?


Can you :
copy your complete solution and remove proprietary (or confidential )  information.
I assume the compile will still fail.
Zip the bare minimum complete solution folder and post it here ( with the .sln and .cproj files)
Someone who has matching specifications may be able to determine the issues.


Personally I'd start with a bare bones solution that compiles and add the references (and code) until it fails.

... and keep notes.

• Remove all references to autocad
• Delete any autocad dll that might have been copied bin folder.
• Clean Solution
• Add reference back and set copy local to false

It is referencing 2012 assemblies somehow because it trying to look in Acmgd instead of AcCoreMgd

Error:

4. Unknown build error, 'Could not load type 'Autodesk.AutoCAD.Runtime.CommandClassAttribute' from assembly 'Acmgd, Version=19.0.0.0, Culture=neutral, PublicKeyToken=null'

Please help.

Thanks very much! I solved the problem.

I had referenced a dll that in turn referenced a previous version of AutoCAD dll. When I removed that dll, the problem is solved.

Thanks
