Problem creating a launcher

EdN · 05-08-2011, 04:52 AM

I am trying to create a launcher in Fedora 13 which will run a simple script named proj4a. I run this script from the command line as follows:
$ $HOME/proj4a >$HOME/proj4a_out
where proj4a is an executable file in my home directory and the output goes into a file, proj4a_out, in my home directory. Everything works fine.
I created a launcher called Proj4a and in the command field I entered the following:
' $HOME/proj4a >$HOME/proj4a_out'
When I click on the launcher it comes back with the following:
There was an error launching the application.
Details: Failed to execute child process "$HOME/proj4a >$HOME/proj4a_out" (No such file or directory)
I can't for the life of me figure out what is wrong here. Does anybody see what I'm missing?

I had a similar problem, which I fixed by putting a script file in the directory where I wanted to run the executable 'rpcemu', and that script was 'runrpcemu'...

Code:

#!/bin/sh
#
# Runs RPCemu
# installed in /home/terry/RPCemu-168

cd /home/terry/RPCemu-168

./rpcemu

My desktop launcher included the line...

Code:

Exec=/home/terry/RPCemu-168/runrpcemu

Not sure if my problem was exactly the same , but it is worth a try.

Cheers,
Terry

The launcher does not run a shell to execute the command so $HOME is treated literally. If you change $HOME to the required value (/home/<your user name>/) it should work.

I tried what you suggested and I now get the following message:
Details: Failed to execute child process "/home/enowak/proj4a >/home/enowak/proj4a_out" (No such file or directory)

I create a launcher by right-clicking my desktop and then clicking "create launcher...".
This produces a box which contains entries for Type:, Name:, Command:, and Comment: .
Did you put the line "Exec=/home/terry/RPCemu-168/runrpcemu" into the command: box?

No, the "Exec=" stuff is generated. You add the path to your shell, in my case it was '/home/terry/RPCemu-168/runrpcemu'.
Once you have created your launcher, you can go to your Desktop dir and drag your new launcher icon to an editor and check/edit the appropriate Exec line.
Here is the text of my launcher to run rpcemu...

Code:

#!/usr/bin/env xdg-open

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=true
Name[en_US]=RPCemu
Exec=/home/terry/RPCemu-168/runrpcemu
Name=RPCemu
Icon=/home/terry/RPCemu-168/src/rpcemu.ico

Hope that sorts it out.

Cheers,
Terry
