I am working for a web application using praat features. I have written a script for that and it is working fine in ubuntu. But now i want to run these .praat scripts in a remote ubuntu server and I have already installed praat but when I run praat it gives me the following error:

(praat:1364): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(praat:1364): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

(praat:1364): Gtk-WARNING **: Screen for GtkWindow not set; you must always set a screen for a GtkWindow before using the window

(praat:1364): Gdk-CRITICAL **: IA__gdk_window_new: assertion 'GDK_IS_WINDOW (parent)' failed Segmentation fault (core dumped)

Please tell me way a that I can run a praat script in remote ubuntu server.

When compiling Praat for use as a server for commands from your web pages, you may not need sound or a GUI. Do

cp makefiles/makefile.defs.linux.nogui ./makefile.defs

which creates the executable praat_nogui. If you don't need graphics (.e.g PNG files) either (i.e. you need only Praat's computation), you can create an even lighter edition:

cp makefiles/makefile.defs.linux.barren ./makefile.defs

which creates the executable praat_barren. Then type make to build the program. If your Unix isn’t Linux, you may have to edit the library names in the makefile.

Also you can download praat6030_linux64nogui.tar.gz or praat6030_linux64barren.tar.gz from https://github.com/praat/praat/releases

I had the same problem and rebuilding praat from source using the makefile.defs.linuxs.pulse configuration solved it for me. I had to do some minor changes to get the build to work. You can find the modifications on github.

Edit: Using makefile definitions from makefile.defs.linux.barren now solves the issue.
