Hi,

I cloned the tkdom repo, opened it, and then tried to build it with the following options:
<pre>./configure --with-tcl='/usr/local/opt/tcl-tk/lib' --enable-html5</pre>
<pre>make</pre>

and I receive the following error:

<pre>
gcc -dynamiclib -pipe  -Os -DNDEBUG -Wall -fno-common -I/usr/local/opt/tcl-tk/include -I/usr/local/opt/tcl-tk/include  -L/usr/local/opt/tcl-tk/lib -L/usr/local/opt/tcl-tk/lib -prebind -headerpad_max_install_names -Wl,-search_paths_first  -Wl,-single_module -current_version 0.9.2 -compatibility_version 0.9.2 -o libtdom0.9.2.dylib xmlrole.o xmltok.o xmlparse.o xmlsimple.o dom.o domhtml.o domhtml5.o domjson.o domxpath.o domxslt.o domlock.o tcldom.o nodecmd.o tdominit.o tclexpat.o tclpull.o tdomStubInit.o -L/usr/local/Cellar/gumbo-parser/0.10.1/lib -lgumbo  -L/usr/local/Cellar/tcl-tk/8.6.10/lib -ltclstub8.6

</pre>

I've experimented with both <pre>--disable stubs</pre> and removing <pre>--enable-html5</pre> and receive the same error when building, in the linking step.

My system:
<pre>
MacOS Catalina
10.15.5
</pre>

My clang version:
<pre>
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin19.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
</pre>

My tcl version:
<pre>
tcl-tk: stable 8.6.10
</pre>

Thanks
