Can I use mono64 with Visual Studio for Mac?

Question

I'm new to Mono development (but not .NET development) - got as far as downloading Visual Studio for Mac and trying to run a sample solution from Alea GPU. It complains that it needs mono64, but I see no option for selecting 64 bit architecture like I would in Windows, and Googling the issue has not turned up an answer I can make sense of. Can I use mono64 in VS for Mac and if so, how?

Answer 1

I got mine to work by setting the Project -> Options to run with 32 bit mono. it all works, see pics.

Answer 2

Since you are running within VS4M, you need to set the architecture of the run configuration that you are using.

Using an ML (Alea-based) program that I wrote as an example:

Within VS4M:

• Open the Project Options and go to Run / Configuration / Default:

• Open the Mono runtime settings and set the Arch to 64-bit:

From the cmd-line:

Mono is 64-bit by default now, so you can run either:

/Library/Frameworks/Mono.framework/Commands/mono MovieMadnessComputeBoxOffice-Alea.exe

or

/Library/Frameworks/Mono.framework/Commands/mono64 MovieMadnessComputeBoxOffice-Alea.exe

Note: On older version of Mono you would have to have used mono --arch=64 .... If you need arch32, you use mono32, but CUDA only has 64 libs so this would not be needed for Alea usage.
