Invalid desktop entry file error - midi2input

Question 1

I decided to use a midi controller for certain tasks, so I've used midi2input for this.

The application compiled with no errors however, when I click on the icon I get:

Invalid desktop entry file: '~/.local/share/applications/m2i.desktop

These are the contents of the desktop entry:

[Desktop Entry] 
Encoding=UTF-8 
Version=1.0 
Type=Application 
Terminal=true 
Exec=/usr/local/bin/ 
Name=Midi2Input 
Icon=/home/emm/midi2input/build/res/icons/hicolor/512x512/apps/m2i-light.png

Any ideas?

The png exists. I've also just altered the Exec line as you suggested and I've also re-built it and it's still giving the same error.

Current desktop entry:

[Desktop Entry]  
Encoding=UTF-8  
Version=1.0  
Type=Application  
Terminal=false  
Exec=/usr/local/bin/m2i  
Name=midi2input  
DBusActivatable=false  
Icon=/home/emm/midi2input/build/res/icons/hicolor/512x512/apps/m2i-light.png  
StartupNotify=true

emm@i3:~$ ls -al /usr/local/bin/m2i
-rwxr-xr-x 1 root root 606864 Jul 21 12:28 /usr/local/bin/m2i
emm@i3:~$ ls -al /home/emm/midi2input/build/res/icons/hicolor/512x512/apps/m2i-light.png

Question 2

Если вы уверены, что указанный файл Exec правильный, прокомментируйте строки в файлах .desktop и попробуйте запустить m2i ], пока вы не определите виновника.

Вы можете комментировать один за другим или комментировать их в виде групп (метод деления пополам).

Пожалуйста, опубликуйте вывод

ls -al /usr/local/bin/m2i
ls -al /home/emm/midi2input/build/res/icons/hicolor/512x512/apps/m2i-light.png

Question 3

Question 4

You have not specified the full path of the executable.

You have only put:

Exec=/usr/local/bin/

See the documentation on Desktop Entry Specification - GNOME Developer

Exec

Program to execute, possibly with arguments. See the Exec key for details on how this key works. The Exec key is required if DBusActivatable is not set to true. Even if DBusActivatable is true, Exec should be specified for compatibility with implementations that do not understand DBusActivatable.

Not to be confused with:

Name

Specific name of the application, for example "Mozilla".
