Unable to compile a file under Linux

[LyesSaadi]

Hello again!

Because it is using Windows-exclusive code, the compiler is unable to compile a program.

Here is the stack trace:

Unhandled exception. System.IO.DirectoryNotFoundException: Could not find a part of the path '/var/home/lyes/.opt/Ncodi/D:/ncodi/cfg.dot'.

   at Ncodi.Program.Main(String[] args) in /var/home/lyes/.opt/Ncodi/src/Nc/Program.cs:line 39

I do not have any experience in C#, but looking at the stack trace, the issue is obviously here:

Ncodi/src/Ncodi/CodeAnalysis/Compilation.cs

Lines 63 to 70 in 47bca33

	var appDirectory = Path.GetDirectoryName(appPath);
	var cfgPath = Path.Combine("D:", "ncodi", "cfg.dot");
	var cfgStatement = !program.Statement.Statements.Any() && program.Functions.Any()
	? program.Functions.Last().Value
	: program.Statement;
	var cfg = ControlFlowGraph.Create(cfgStatement);
	using (var streamWriter = new StreamWriter(cfgPath))
	cfg.WriteTo(streamWriter);

Looking at it, I wouldn't be surprised if it also causes issues in Windows systems, since it is looking for a configuration file in a hard-coded path.

NOTE: I used compile here, but I have no idea if it's doing any compilation or not TBH since I wasn't able to execute it yet :P !

I changed the code when testing and forgot to change it back my bad
Line 64 should be like this
var cfgPath = Path.Combine(appDirectory, "cfg.dot");

If you use the Ncodi.Cli to execute some .ncodi file you will find a cfg.dot generated there it contains a graph visualization of how the code was ran. Simply open it in a text editor copy the data in it and paste it in a graphviz renderer like this (make sure the engine is set to dot) https://dreampuf.github.io/GraphvizOnline/
I used this mainly for debugging but it's cool to see :)
