Cannot debug fsharp program

[anquegi]

Sorry for writing a question, but I couldn't figure this out, I'm trying to debug a fsharp program or a dotnet core application but I cannot get it working, I read this two issues: https://github.com/mono/sdb/issues/42 and https://github.com/mono/sdb/issues/51

But I always get the same result nothing, this is my setup:

➜ which mono
/Library/Frameworks/Mono.framework/Versions/Current/Commands/mono

And then I create a fsharp file like:

functional-programming/fsharp/temp took 11s
➜ cat Program.fs
namespace ABC
module DEF =
    let bar() =
        stdout.WriteLine("abc")

    let foo (str:string) =
        stdout.WriteLine(str)
        bar()

    [<EntryPointAttribute>]
    let main _ =
        let s = "Foo!"
        foo s
        stdout.WriteLine("callmekohei")
        0

functional-programming/fsharp/temp took 3s
➜ ls
FSharp.Core.dll Program.exe     Program.exe.mdb Program.fs

and then try to run sdb:

functional-programming/fsharp/temp
➜ fsharpc --debug+ Program.fs

functional-programming/fsharp/temp took 3s
➜ ls

functional-programming/fsharp/temp
➜ sdb

'RuntimePrefix' = '/Library/Frameworks/Mono.framework/Versions/Current/Commands/' (was '/Library/Frameworks/Mono.framework/Versions/Current/Commands/')
(sdb) bp add func ABC.DEF.foo
Breakpoint '0' added for method 'ABC.DEF.foo'
(sdb) r Program.exe
Failed to connect to 'Program.exe'
(sdb)

I do not know what to do now, or where to go,

Sorry for that reading the readme part I read the RuntimePrefix, And is important that this expect a bin folder withi is not in my setup:

/Library/Frameworks/Mono.framework 
➜ ls -l
total 0
lrwxr-xr-x  1 root  admin   55 24 jun 23:49 Commands -> /Library/Frameworks/Mono.framework/Versions/Current/bin
lrwxr-xr-x  1 root  admin   59 24 jun 23:49 Headers -> /Library/Frameworks/Mono.framework/Versions/Current/include
lrwxr-xr-x  1 root  admin   52 24 jun 23:49 Home -> /Library/Frameworks/Mono.framework/Versions/Current/
lrwxr-xr-x  1 root  admin   55 24 jun 23:49 Libraries -> /Library/Frameworks/Mono.framework/Versions/Current/lib
lrwxr-xr-x  1 root  admin   73 24 jun 23:49 Mono -> /Library/Frameworks/Mono.framework/Versions/Current/lib/libmono-2.0.dylib
drwxr-xr-x  4 root  admin  128 24 jun 23:49 Versions

So I change the runtimeprefix to:

(sdb) cfg s RuntimePrefix /Library/Frameworks/Mono.framework/Versions/Current/
'RuntimePrefix' = '/Library/Frameworks/Mono.framework/Versions/Current/' (was '/Library/Frameworks/Mono.framework/Versions/Current/Commands/')

Then finally it worked:

functional-programming/fsharp/temp took 2m 38s ➜ ls FSharp.Core.dll Program.exe Program.exe.mdb Program.fs

functional-programming/fsharp/temp ➜ sdb Welcome to the Mono soft debugger (sdb 1.6.7116.16617) Type 'help' for a list of commands or 'quit' to exit

(sdb) bp add func ABC.DEF.foo
Breakpoint '0' added for method 'ABC.DEF.foo'
(sdb) run Program.exe

(sdb)

I will close this issue, but I think that this could help for documenting this setup

@anquegi

if you do trace source code , please add --optimize- :-)
