I have installed monodevelop and have written a hello world program in C# console but when in run configuration I choose "run in external console" check box and click on run button monodevelop says: Cannot execute "{Project Path}"
Os: Debian, Kali 2
Edit: and Console.ReadLine() Doesn't work in default run configuration.
I had the same problem, here is my solution.
OS: Linux Mint 18.1 Cinnamon 64-Bit
Monodevelop: 6.1.2.44 flatpak installation
afaik MonoDevelop needs xterm or gnome-terminal for running a program in an external console. If both are missing you get "Cannot execute..." errors.
The MonoDevelop log shows:
~/.var/app/com.xamarin.MonoDevelop/cache/MonoDevelop-6.0/Logs/Ide.log
ERROR [2017-01-10 19:47:49Z]: Cannot execute "/home/...exe"
System.InvalidOperationException: Cannot start process because a file name has not been provided.
In my case i had to install xterm and copy it and it's dependencies to the flatpak runtime:
sudo apt-get install xterm
cp -v /usr/bin/xterm ~/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/1.4/active/files/bin/
cp -v /usr/lib/x86_64-linux-gnu/libXaw* ~/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/1.4/active/files/lib/
cp -v /usr/lib/x86_64-linux-gnu/libXmu* ~/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/1.4/active/files/lib/
cp -v /usr/lib/x86_64-linux-gnu/libutempter* ~/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/1.4/active/files/lib/
cp -v /lib/x86_64-linux-gnu/libpng12* ~/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/1.4/active/files/lib/
cp -v /lib/x86_64-linux-gnu/libtinfo* ~/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/1.4/active/files/lib/
Maybe not the best solution but it works for me.
I found a couple of ways around this:
1.
Instead of creating a console application, create a GTK 2.0 project. For example:
using System;
using Gtk;
namespace Test
{
class MainClass
{
public static void Main(string[] args)
{
/*Application.Init();
MainWindow win = new MainWindow();
win.Show();
Application.Run(); */
Console.WriteLine("Hello World");
}
}
}
And in the Application Output pad, you will see "Hello World".
mono-runtime (sudo apt-get install mono-runtime)
and go to the bin/Debug/ directory. There you will find an .exe file and you can simply execute it as ./{{NameOfProject}}.exe
I had this problem on on Ubuntu 20.04 (using the latest monodevelop from PPA)
It was because on 20.04,
gnome-terminal-server had moved from /usr/lib/gnome-terminal/ to /usr/libexec/
Monodevelop needs to be updated to take care of this.
My temporary fix:
cd /usr/lib
sudo mkdir gnome-terminal
sudo ln -s /usr/libexec/gnome-terminal-server
Here's an automated two-liner for the "copy xterm" approach (tested on Ubuntu 16.04):
ldd `which xterm` | awk '{if ($2 == \"=>\") print $3}' | grep / | xargs -I{} cp -Lnv {} .local/share/flatpak/runtime/org.freedesktop.Sdk/x86_64/1.4/active/files/lib/
cp -nv `which xterm` .local/share/flatpak/runtime/org.freedesktop.Sdk/x86_64/1.4/active/files/bin/
I had to open a terminal window in Linux Mint Sylvia, and switch to the Project's name, then from there to the bin/Debug folder. I saw that there was an exe created by monoDevelop. I changed the exe's mode to executable. Then I ran the exe by typing its name.exe and it worked.
