Question

I would love to have a little problem solved. I know that it’s not the best way to debug a piece of code with possible warnings, but I love to debug all the time when I have a little break between to ideas. I just found out about mono and the possibility to compile C# code running on Mac OS X Mountain Lion. I integrated it in the CodeRunner app, and it works without any problems. However, if there appears a warning in the code, it does not work.

For example, I tried to compile a code that creates one integer (nothing more than that) and it was not debugging because of that warning. I’m getting this error message:

Untitled.cs(9,29): warning CS0219: The variable `test' is assigned but its value is never used
Cannot open assembly 'Compilation succeeded - 1 warning(s)
Untitled.exe': No such file or directory.

Someone may know how to deal with that. I know it’s not an essential feature, but I would love to debug the code even with some unused variables.

The content of the compilation script file:

#!/bin/bash

enc[4]="UTF8"            # UTF-8
enc[10]="UTF16"            # UTF-16
enc[5]="ISO8859-1"        # ISO Latin 1
enc[9]="ISO8859-2"        # ISO Latin 2
enc[30]="MacRoman"        # Mac OS Roman
enc[12]="CP1252"        # Windows Latin 1
enc[3]="EUCJIS"            # Japanese (EUC)
enc[8]="SJIS"            # Japanese (Shift JIS)
enc[1]="ASCII"            # ASCII

# Otherwise output the name of the input file without extension (this should be the same as the class name)

dmcs -out:"$4"/csharp-compiled/"$classname".exe "$1"

dmcs puts some messages on stdout, and some on stderr. CodeRunner expects stdout to only contain the output file name, nothing else, so to make that happen, >&2 can be used to redirect everything else to stderr.

dmcs -out:"$4"/csharp-compiled/"$classname".exe "$1" >&2
