Builind on Ubuntu-Gnome 22, location of submodule?

[octimis]

After running ./autogen.sh --prefix=/usr , from the instruction here (link).

I got the errors:

configure.ac:307: error: required file 'mate-submodules/Makefile.in' not found
configure.ac:307: error: required file 'mate-submodules/libegg/Makefile.in' not found

I found the following thread with the same issue:
#1560

I have 'git' installed but no submodule:
:$ git submodule init
fatal: not a git repository (or any of the parent directories): .git

I came across this website on adding a submodule, but the issue is I don't know what url to use for the submodule:
git submodule add [submodule-repository-url]

To run git submodule init and git submodule update you need to have the .git folder from cloning the repo in the directory you are running it from. Alternately, in the releases the necessary files for the build (no use of git needed) will be found in mate-submodules and the libegg directory within it. These can be copied to other caja build directories of course, and then the package should be ready to configure and build. Moving these to a subproject allows them to be kept in sync across all packages that use them

There's no .git folder in the caja-master.zip file. The caja-master/mate-submodules/ folder is blank.

There wouldn't be, that's a snapshot of the package not the repo itself. You need git clone to copy the repo to run git on, or to download one of the RELEASES from https://pub.mate-desktop.org/releases/1.28/ to copy the files from

That helped. Thanks.
I copied and pasted the folder mate-submodule from the link you provided. Alternatively I also tried using the folder from here, and I got the message:

libcaja-extension/Makefile.am:70: error: HAVE_INTROSPECTION does not appear in AM_CONDITIONAL
autoreconf: error: automake failed with exit status: 1

I also deleted the caja files from initial execution of ./autogen.sh --prefix=/usr, and unzipped caja-master again.

Edit: installing gobject-introspection partially solved the issue, but now it's saying certain packages can't be found even though they're clearly installed according to 'synaptic package manager' and 'apt-file'.

I've never done it this way, the error you got on the 2nd method looks like a version mismatch but I cannot really diagnose this

I edited my previous post, and was able to get caja to compile.
I followed the instructions here, to enable the viewing of large thumbnails.
Unfortunately the invidiual icons are still spaced far apart and the image is blurry, instead of just using the original image source (not pictured). I.e. it's like an image that is originally 150x150 is stretched out to 250x250. The images work as desired in Dolphin file browser with command shown in the linked post.
I also went to Edit>Preferences>Preview, and set 'only for files smaller than' to 4 GB, still not working.

Edit: After deleting everything inside ~/.cache/thumbnails the pictures load their resolutions properly but not for video files, even those with embedded thumbnails. I didn't have to do this with Dolphin.

This is unrelated to the orginal issue
