LNK2019 error- exampleMain

[Andrea Roberti]

Hi guys, i'm having linker error LNK2019.

I followed tutorials, but i've only one thing different : i'm using Visual Studio 2013 Express.
So in Cmake my current generator is Visual Studio 12

I checked everything (libs, building 32, debug etc) , and also read old topic (https://simtk.org/forums/viewtopic.php? ... 1120#p7764)

I've also had another problem -> signbit already has a body (in common.h and Scalar.h) and I solved it by adding

#if _MSC_VER < 1800
[ .......signbit.......]
#endif

Andrea

Solved!

The problem was the Installer.

OpenSim-3.2.0-win64VC10P.exe ----changed ---> OpenSim-3.2.0-win32VC10P.exe

and it works!

Thanks Adrea for reporting back.

Looks like the problem was trying to build 32 bit application using the 64 bit libraries. While doing CMake configuration you should be able to choose the build environment that matches your installer ( win64 for 64 bit).

Do you still need to make the change to handle signbit?

If i use Visual studio 2013 express i've still to change the headers (common.h and Scalar.h)

I used CMake with the Visual Studio 10 2010 Win64 generator.
I can build the file with Visual Studio and run the .exe file in the Release folder.
However, when I click the Green arrow in Visual Studio to run the file I get the following error:

Unable to start program 'C:\OpenSimWorkspace\ExampleMain\build\x64\Release\ALL_BUILD'
The system cannot find the file specified.

What would be the problem?

[Ayman Habib]

Hi Kevin,

When you hit the run button in VisualStudio it tries to run the current project (shown in bold in Solution Explorer). It looks like your current project is ALL_BUILD which builds everything but is not a program to run. In order to run the program, make it the current project (right mouse click on ExampleMain and select "Set as Startup Project" and then it will run the correct program when you hit the green arrow.

Hope this helps,
-Ayman

[Kevin Tanghe]

Yes, this works. Thank you.

Dear Ayman& Andrea

I'm new to opensim and have been following the tutorial

I was managed to configure and generate in Cmake using visual studio 2015 but I couldn't build the solution for ALL_Build and kept getting the same LNK2019 error.

I installed the opensim 3.3 64bit. I understand that it was the "trying to build 32bit application with 64bit library" thing (Is there any 64bit library in opensim 3.3) but would it be possible to alter the examplemain to 64bit application?

What is the differences between opensim 3.3 32bit and 64bit?

Best regards,
Leosky

Dear everyone,

I have a problem while running myAnalysis.cpp in the Creating Your Own Analysis example.
I use visual studio 2015 running on window7 32bit
Its built successfully but cannot debug
I tired to set the myAnalysisPlugin as a startup project already,
but it showed
Unable to start program
'C:\OpenSimWorkspace\sdk\APIExamples\Plugins\AnalysisPluginExample-build\Release\myAnalysisPlugin.dll'.

C:\OpenSimWorkspace\sdk\APIExamples\Plugins\AnalysisPluginExample-build\Release\myAnalysisPlugin.dll is not a valid Win32 application

I did everything according to the example. Did I miss something?
Could anyone please recommend what should I do?


Thank you,
Tanya
