I got it to configure it

compile and install "apparently" successfully, but "package require TclMagick"
spews out:

   /usr/local/lib/TclMagick0.45/libTclMagick.so: undefined symbol:

I gave it another try afterall - with graphicsmagick.

I switched to graphicsmagick.
(This also removes imagemagick)
#tcl-dev and tk-dev are already installed
apt install graphicsmagick-imagemagick-compat
apt install graphicsmagick-libmagick-dev-compat

Ok, did that, too...

Downloaded the graphicsmagick source and created the TclMagick
subdirectory from it

You seem to have found a version 0.46 ...

The link to sourceforge seems to offer only 0.40 to 0.45 (all
from year 2005) and their cvs servers seem no longer active
(connection timeout after about 2 minutes)

So, please, let me know where you got 0.46 from.


With 0.45, this is what I get (now with graphicsmagick):

./configure

With those graphicsmagick packages installed, there existed now
an executable /usr/bin/Wand-config which I had to pass to configure
as: --with-magick=/usr/bin/Wand-config

(otherwise, configure would abort with "configure: error: You must
specify the Graphics/ImageMagick-config script with --with-magick!")

make install

build-process emits a big number of warnings, about sign-conversions...
but it seems to end with success.

This is the line that creates the dynamic lib:

gcc -shared  .libs/libTclMagick_la-TclMagick.o  -L/usr/lib -ldl
-lGraphicsMagickWand -lGraphicsMagick -ljbig -lwebp -lwebpmux -lheif
-lde265 -llcms2 -ltiff -lfreetype -ljpeg -lpng16 -lwmflite -lXext -lSM
-lICE -lX11 -llzma -lbz2 -lxml2 -lz -lzstd -lm -lpthread -lgomp
-Wl,-Bsymbolic-functions -Wl,-z -Wl,relro -Wl,-z -Wl,now -Wl,-soname
-Wl,libTclMagick.so.0 -o .libs/libTclMagick.so.0.0.0

To my surprise, this neither links to stubs nor to any -ltcl at all.

But still:
$ tclsh
% package require TclMagick
couldn't load file "/usr/local/lib/TclMagick0.45/libTclMagick.so":
/usr/local/lib/TclMagick0.45/libTclMagick.so: undefined symbol:
tclStubsPtr
%

I don't see how I could change any linking to stubs...
Adding  --with-tcl=/path/to/tcl8.6.14/unix to configure also didn't
change anything.
