How to execute the application ?

[rmantovani68]

Hello Mirko,

I am trying to build and execute the example application.
I tried :

mkdir _build
meson _build
cd _build
ninja

after these operations I get the _build/src directory containing:

roberto@roberto-virtual-machine:~/prj/examples-MyFirstApplication-main/_build/src$ ls -l
total 8
-rwxr-xr-x 1 roberto roberto 1265 Dec 13 11:25 myfirstapplication
-rw-rw-r-- 1 roberto roberto 2416 Dec 13 11:25 myfirstapplication.gresource
roberto@roberto-virtual-machine:~/prj/examples-MyFirstApplication-main/_build/src$ 

If I try to execute the file 'myfirstapplication' I get this result:

roberto@roberto-virtual-machine:~/prj/examples-MyFirstApplication-main/_build/src$ ./myfirstapplication 
Traceback (most recent call last):
  File "/home/roberto/prj/examples-MyFirstApplication-main/_build/src/./myfirstapplication", line 37, in <module>
    resource = Gio.Resource.load(os.path.join(pkgdatadir, 'myfirstapplication.gresource'))
gi.repository.GLib.GError: g-file-error-quark: Failed to open file “/usr/local/share/myfirstapplication/myfirstapplication.gresource”: open() failed: No such file or directory (4)

What I need to do to execute the application ?

Here the output of the command executed:
