My Intent
I have an image generated by BitBake on which I'm interested in changing the window manager to metacity or maybe something similar.
My Process
I've added require recipes-graphics/images/core-image-x11.bb into my core recipe, which provides a simple Matchbox terminal window but seemingly no other functionality. If I add matchbox-desktop and matchbox-session-sato, it adds a bit more usability but not what I'm looking for.
I've included the default package from the metacity_2.34.13.bb recipe from the meta-gnome layer from the OpenEmbedded Metadata Index in the IMAGE_INSTALL variable of my core image. This installs several components including a metacity command in /usr/bin. If I run that command, I get the following message:
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications
(metacity:1124): GLib-GIO-ERROR **: Settings schema 'org.gnome.metacity' is not installed
Trace/breakpoint trap
I've navigated to /usr/share/glib-2.0/schemas and run glib-compile-schemas ., then run:
startx
metacity --replace
again. Now, the output is:
Window manager error: Unable to open X display
I haven't found a clear solution to this error which applies to my specific situation.
Update (2/29):
I may have now found a solution to this error, using these commands:
X&
export DISPLAY=:0
metacity&
At this point, I seem to be running something on one of my VTs. I can run demos like glxgears in that VT (glxgears is included in the mesa-demos recipe), but I don't know how to actually create a usable environment.
My question(s)
I'm not using much from meta-openembedded/meta-gnome (just metacity) or meta/recipes-gnome (adwaita-icon-theme, gnome-desktop3, gsettings-desktop-schemas and gtk+3), so am I missing some recipe which automates the addition of metacity?
(if not Question 1) How can I solve the error Window manager error: Unable to open X display?
The x11-common recipe adds a X session script that will run /usr/bin/x-session-manager: that is responsible for starting your desktop environment.
The way to implement a new session/DE in OE-Core is to use update-alternatives for "x-session-manager": see the matchbox-session recipe for the default implementation and mini-x-session recipe for an alternative.
mini-x-session might be modifiable for your needs so you don't need to write a new one: A /etc/mini_x/session file like this might do the trick:
# start any apps here, e.g. "my-desktop &"
exec metacity
Going from this (a running window manager) to "usable environment" might still be lots and lots of work, depending on your definition of usable.

I really hope that someone could help me out with my problem.
I want to start an exe File (VSeeFace - see https://www.vseeface.icu for more information) on my Mac with wineskin. VseeFace is an application for Vtubing.
The application starts normally via Wineskin, but as soon as I try to open my avatar (a .vrm file), the software stops and I don't know why. I have searched everywhere and found nothing about my problem, but perhaps that is also due to my limited knowledge of development skills.
Can anyone help me please?
My Mac:
MacOS Monterey Version 12.4
Radeon Pro 575X 4 GB
My Wineskin Setup:
Wrapper Version Wineskin 2.9.1.5
Engine WS11WineCX64Bit22.0.1-1
Config Utility - Windows-Version 8
VseeFace Software – https://www.vseeface.icu/#download
They also describe how it will work on Linux or maybe Mac,
https://www.vseeface.icu/#running-on-linux-and-maybe-mac
For the Facetracking I run OpenSeeFace (but that seemed to work, I could see the green light of the iMac camera, but I couldn't test it because of my software problem).
I mean I could run the application but on the most important Screen it stops working.
In the debug.log file I noticed the following messages:

I have a Windows 10 laptop where no TeX distribution was ever installed before (double-checked for config directories, files, and environment variables).
Wanting to install TeX Live 2021, I followed the full installation guide and also read the Windows-specific warnings. I've now tried several times, following different installation procedures - cleaning up everything (deleting base & user directories, environment variables, etc) before each time - but still don't manage to get a working installation. Before I report a bug at tex-live#tug, I wanted to ask for advice here, in case I'm doing something wrong. Here is what I did, step by step, and the problems I encountered in the process.
1. First I tried running the recommended online installer install-tl-windows.exe. It never got past the screen that tries to contact or load from a repository, even after a 30-min wait. Tried a dozen times, choosing different mirrors nearby and far away. No luck.
2. Then I downloaded and unpacked the install-tl.zip and run install-tl-windows.bat therein. This time the main installation window appeared. I left all default paths and environment variables (note that I do have write access to C:); in the selection scheme I unselected all languages except US & UK English, unselected XeTeX, LuaTeX, ConTeXt; also unselected TeXworks (I use Emacs), and clicked Install. After one to three hours (depending on the mirror I chose), the installation was complete.
I tried compiling a minimal latex document (see below), and got an error similar to the one in this old question:
I can't find the format file `pdflatex.fmt'
Following the advice in the answers to that question and similar questions elsewhere online such as this, I tried running texhash and fmtutil-sys --all. The latter gave the error
no appropriate script or programme found fmtutil.
for which there are also many posts online.
2a. Not understanding what the problem could be, I re-tried with all possible combinations of the following three options: (a) choosing different mirrors; (b) leaving the full selection of packages (ie without unselecting some languages, LuaTeX etc); (c) redoing the procedure by choosing "Run as Administrator". No luck.
3. At this point I tried downloading the ISO file with the full installation. Mounted the image and run install-tl-windows.bat (as normal user, as recommended; I repeat that I do have write access to C:). Everything proceeded as in step 2. above. At the end of the installation I tried running pdflatex on the minimal latex document. New error this time:
This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2021/W32TeX) (preloaded format=pdflatex)

! LaTeX Error: File `article.cls' not found.
Very strange. A file search revealed that article.cls is in the TeXLive file system; but kpathsea did not see it indeed.
4. At this point I opened the TeX Live Shell from the Start Menu; selected a CTAN mirror; updated the TL Manager which was not up to date; updated all packages; run Regenerate filename database; and run Regenerate formats. With the latter I got this error:
tex live shell:

I tried to continue anyway with Regenerate fontmaps, and then tried again pdflatex on the minimal document. New error:

(Fatal format file error; I'm stymied)
5. I tried again steps 3. and 4., but with "Run as Administrator". Same errors.
OK at this point I give up and really don't know what to do. Am I doing something wrong? For the moment I have to concur with this post: installation of TeX Live 2021 is an utter failure.
Here is the minimal latex file I used for testing (copy & paste):
\documentclass{article}
\begin{document}
test
\section{Section}
test
\end{document}
Found, that the download is not working because the system path to "cmd.exe" is not found. Therefore: open a cmd window and add the system path prior to starting the .bat file (set PATH=%PATH%;C:\Windows\system32)
I am trying to build a python 3.5 environment that supports an old hddm library. Standard approaches fail due to my/anaconda's apparent inability in ignore (or downgrade) the 10.1 cuda library in favor of an older one that works with hddm.
There is a yml file available that describes a successful environment. But the advertised command
conda env create -file hddm_py35.yml
fails with an error listing all of the packages "not found." Here are the errors.

The failure occurred within seconds. I get the feeling that conda didn't even try to look for these packages!?!?
Am I supposed to download these packages, put them somewhere, and then tell conda to find them on my hard drive?
Is there a flag that tells conda to do its usually find-and-load for all "missing" packages -- but only in the environment I'm describing? In my base environment (3.8) I don't wish to downgrade.
Should make a new 3.5 environment and then work through the list one-by-one and uninstall/remove/downgrade each package by hand?
Meta question: This must be a FAQ, and yet I'm not able to google for the answer. That usually means googling for "conda install environment from yaml file" doesn't contain the appropriate vocabulary for, well, trying to induce conda to install an environment from a yaml file. What question should I have asked?
1) Am I supposed to download these packages, put them somewhere, and then
tell conda to find them on my hard drive?
Not necessary. But searching for the versions on anaconda.org helps identify channels for one-by-one manual download.
2) Is there a flag that tells conda to do its usually find-and-load for all
"missing" packages -- but only in the environment I'm describing? In my base
environment (3.8) I don't wish to downgrade.
There is no evidence that conda will automatically download files listed in a yaml file that are missing in the present environment.
3) Should make a new 3.5 environment and then work through the list one-by-
one and uninstall/remove/downgrade each package by hand?
Yes.

There is no evidence that yaml files are anything other than lists of version of packages in an environment. They cannot be used to make new environments (unless all of the components are already present in the host environment, maybe) so their value is largely annotative. Evidently.
For the case of making an environment for hddm in 2020, well, don't try. Cuda support will work against you. There is a hddm host at https://colab.research.google.com/ that is properly configured (without cuda disruption) so that you can use it to kick tires, etc. Getting hddm to work in any other context probably requires dedicated hardware so that the cuda driver can be manipulated for this application only and not break any other applications in the process.
I have successfully built OpenDDS 3.13.2 from source. Here is my environment:
Windows 10
Visual Studio 2017 (re-targeted Solution to SDK 10.0.17763.0)
Tried all Configuration/Platform combinations
I successfully used the configure script from the VS command prompt, built everything by opening the generated solution in the same command prompt, and finally ran the Messenger example (publisher and subscriber), and even configured it to use RTPS successfully.
However, when I try to create my own IDL and use the tao_idl, it crashes. Here's my test (using the proper environment from setenv.cmd):
> tao_idl (no args)
IDL: No input files
Second test:
> tao_idl Test.idl (crashes)
I get no error message, and am unable to locate logs or any indication of what went wrong. The same thing happens when I used opendds_idl.
What is the best approach to debug this, and/or are there pre-built binaries available for the IDL compiler(s) (both TAO and OpenDDS)?
After about a day of troubleshooting, I have determined a solution. Despite being able to call tao_idl and opendds_idl yourself, you should basically never do it. There are a good amount of command-line arguments needed to get both to work, and if they're not present, each exe will crash without the proper reasoning why.
I will add my steps below to create a new basic two-exe pub/sub project using OpenDDS:
Create your own IDL file.
Starting with the DCPS Messenger example, modify the .mpc file, replacing Messenger.idl with your IDL file name.
Create a new file called <your project>.mwc, and add the following contents:
workspace {
// the -relative and -include cmdlines make it so this workspace
// does not have to be in the $DDS_ROOT directory tree.
// tell MPC to substitute our DDS_ROOT environment variables for relative paths
cmdline += -relative DDS_ROOT=$DDS_ROOT
// tell the projects where to find the DDS base projects (*.mpb)
cmdline += -include $DDS_ROOT/MPC/config
}
Open a new VS command-line terminal and run $DDS_ROOT/setenv.cmd, or open a regular terminal if you have those environment variables set via Windows settings.
Navigate to your project directory and call: mwc.pl -type vs2017, replacing "vs2017" as needed for your build tool/IDE.
Open up the generated solution, and retarget it as necessary for your Windows SDK version.
Build the <your project>_IDL project first. If you notice in the output window, it is invoking the tao_idl and opendds_idl commands automatically. You can view the .vcxproj files to see the full command-line arguments that were the original problem.
Modify the publisher.cpp, subscriber.cpp, and DataReaderListenerImpl.cpp files to match your new IDL. Run the example as usual and ta-da!
For completeness, the full commands for both tao_idl and opendds_idl are as follows:
> opendds_idl -Sa -St "<your file>.idl"
> tao_idl -Wb,pre_include=ace/pre.h -Wb,post_include=ace/post.h -I$(TAO_ROOT) -Sa -St -I$(DDS_ROOT) "<your file>.idl"
> tao_idl -Wb,pre_include=ace/pre.h -Wb,post_include=ace/post.h -I$(TAO_ROOT) -Sa -St -I$(DDS_ROOT) "<your file>TypeSupport.idl"
I use GTK3 , codeblcks IDE, glade3 in windows 7...
In my application i have a button which when clicked should open a gtk_file_chooser_dialog...
But gives the fillowing error..
Glib-GIO-ERROR**:No GSettings schemas are installed on the system
static void on_save_clicked(GtkWidget *widget,gpointer data)
{
GtkWidget *dialog;
//dialog=gtk_file_chooser_dialog_new("Save it",GTK_WINDOW(gtk_builder_get_object(builder,"mainwindow")),GTK_FILE_CHOOSER_ACTION_SAVE,GTK_STOCK_OK,GTK_RESPONSE_OK,GTK_STOCK_CANCEL,GTK_RESPONSE_CANCEL);
//dialog=GTK_FILE_CHOOSER_DIALOG(gtk_builder_get_object(builder,"filechooserdialog"));
gtk_widget_show_all(dialog);
gint resp=gtk_dialog_run(GTK_DIALOG(dialog));
if(resp==GTK_RESPONSE_OK)
g_print("%s\n",gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(dialog)));
}
I use g_signal_connect(...) to call this function when the button is clicked...
I cannot understand the problem...
I got the very same error when trying to open a FileChooserDialog.

I 'm running a Gtk3 interface with python3 on Linux.
Gtk3 and all its dependencies were installed from the sources.
I found the solution on this forum http://forum.tinycorelinux.net/index.php?topic=13699.0
I just set XDG_DATA_DIRS variable with the path to where the gtk schema files are located and it works.
$ ls /home/user1/ctcils/dusserm/applications/gtk/3.12.1/share/glib-2.0/schemas/
gschemas.compiled org.gtk.exampleapp.gschema.xml org.gtk.Settings.FileChooser.gschema.xml
org.gtk.Demo.gschema.xml org.gtk.Settings.ColorChooser.gschema.xml
$ export XDG_DATA_DIRS=/Produits/publics/x86_64.Linux.RH6/glib/2.40.0/share/:/home/user1/ctcils/dusserm/applications/gtk/3.12.1/share/
There are probably few errors in there.
If you commented both, the dialog.show_all () will produce error because, it hasn't been instantiate yet you asked to be shown.
If you use the first one, object Gtk.FileChooserDialog param has to end with NULL (in c), read the doc
If you use the second one, check your glade signal property in your glade window
Check your gtk installation
Quoting from this StackOverflow answer,
Seems you're not the one having this problem, and it also happens on Windows on MinGW. Luckily, that person gave a solution:
The thing, as it seems as I was running the test-widget example (that I
built with gtksourceview-3.0.0 using MSVC), was that I need to compile the
org.gtk.Settings.FileChooser.gschema.xml file (from GTK+-3.x, under
$(srcroot)/gtk) with the glib-compile-schemas utility that is from GLib,
which will generate gschemas.compiled in the same folder.
After that, place that gschemas.compiled file in the this folder:
$(parent_folder_of_the_gtk3_dll)\share\glib-2.0\schemas
and one will be set to use the gtkfilechooser without the puzzling
[GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser'
is not installed] error.
I will add to my GLib project files to compile the glib-compile-schemas
utility and add to my GTK+-3.x project files to compile the
the org.gtk.Settings.FileChooser.gschema.xml shortly.
