I just installed the latest Ubuntu Desktop 21.10 and built Tcl.

But Tk is not building on Ubuntu from the unix directory.

How can I get Tcl/Tk built and installed properly on Ubuntu please?

Don't the tk sources come with their own ./xlib/X11/Xlib.h ?
Maybe it is a matter of making sure that directory is in one of those "-I" (<--uppercase i) include paths?

That is a "fake" xlib/X11/Xlib.h for MS-Windows and MacOSX. Tk is written in terms of XLib and under MS-Windows and MacOSX some of the XLib-isms are
"faked" in terms of MS-Windows or MacOSX GUI features. Under actual UNIX or Linux, Tk uses the Xlib.h provided by X11. A typical Linux distro separates the X11 runtime (shared) libraries from the X11 development stuff (header
file, link libraries, etc.). Commonly a normal Linux Desktop install just installs the runtime. It is necessary to install the -dev (-devel under RedHat-ish distros) packages if one plans on building tcl/tk from sources.

The OP *could* have just installed tcl and tk from the distro:

sudo apt install tcl tk

But I guess he wanted to build from source...

Hi I know this is an old post but I've been through every forum trying to fix this issue. I need tkinter for my ubuntu virtual machine, I've checked im in the correct python, installed all the packages including the one Robert suggested (though
installing from distro so I shouldn't have to). Nothing. I even tried manually copying the tk8.6 directory into lib and tcl8.6, no effect.
Just:

lewie@lewie-virtual-machine:~/Downloads$ python3

self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)

/usr/local/lib/tcl8.6/tk8.6 /usr/local/lib/tk8.6 /usr/lib/tk8.6 /usr/lib/tk8.6 /lib/tk8.6 /usr/library

This probably means that tk wasn't installed properly.

incidentally the /tk8.6/ dir only contains "pkgIndex.tcl"
in case that's what's wrong.

Any help would be great

This probably means that tk wasn't installed properly.

incidentally the /tk8.6/ dir only contains "pkgIndex.tcl"
in case that's what's wrong.

This is strange at the very least. Besides pkgIndex.tcl, there should be
a folder with a lot of support files (scripts, icons, demos,...). It is basically this stuff:

https://github.com/tcltk/tk/tree/main/library

So maybe the package from your distro is simply broken? Or, the package
from the distro is installed somewhere else, and Tcl picks up a broken
version first and can't find the right version. You can check the path
where Tcl looks for packages like this:

(base) Apfelkiste:~ chris$ python3

import tkinter
interp=tkinter.Tcl()
interp.eval("set auto_path")

'/Users/chris/bin/anaconda3/lib/tcl8.6 /Users/chris/bin/anaconda3/lib'

and afterwards try to load Tk manually:

interp.eval("package require Tk")

'8.6.10'

then this should tell you, which version was loaded:

interp.eval("package ifneeded Tk 8.6.10")

'load /Users/chris/bin/anaconda3/lib/libtk8.6.dylib Tk'
