Hi, I am trying to execute my C# program on Lubuntu 22.04 and 24.04 using mono.
I was able to run my C# program on AMD64 Lubuntu 22.04 and 24.04.
However, when I tried to run it on ARM64v8a, aarch64, it didn’t work properly with this error message;
$ mono MyProgram.exe
And then I got this;
Unhandled Exception:
System.ArgumentException: A null reference or invalid value was found (gdi+ status: invalidparameter)
Weird thing is, when I tried to run my c# program using mono on GNOME Ubuntu 22.04 or 24.04, which are desktop version, on my ARM64 device, it works properly in both OS.
I suspect some sort of problem with cross compiling but you’d need to check with a C# developer, particularly one familiar with cross compiling on Mono in Linux.
This is not really the right forum for that. It’s possible such a person exists here, but they could also exist any number of places. Similarly, a person interested in livecoding might exist here, but this would not be the place I would expect to find the largest number of people with the most experience in the subject.
You should ask at the appropriate Mono forum. They suggest Stack Overflow.
