I haven't thought about Web REDUCE for a while, but I guess it's time that I did!</div>

15 April 2024: The version currently on the REDUCE web site is the latest revision of REDUCE built using Emscripten 2.0.34, because I have had problems using later Emscripten versions.</div>

So "/csl/new-embedded/for-emscripten/Makefile" should reliably build REDUCE 6745 using Emscripten 2.0.34.</div>

If somebody with the appropriate expertise can get the latest version of REDUCE to build with the latest version of Emscripten then that would be great; please let me know how to do it!</div>

In the meantime, I have more or less decided to stay with the build that currently works, but to update the version of REDUCE, i.e. the packages directory. I think that should work although I haven't actually done it yet.</div>

Once you have built REDUCE, you can play around with it using Node.js or the web files in the for-emscripten directory. And, of course, you can play around with Web REDUCE.</div>

As for "known problems", I list some on the web site, but I'll try to say a bit more later when I have more time, maybe tomorrow. But a key problem is the inherent asynchronicity of JavaScript/WebAssembly.</div>

<div style="font-size:11pt">Thanks, that's very helpful! I assumed that because the github<br>
version describes itself as a 'mirror' it would have exactly the same<br>
code in it, but apparently not: I tried the svn version and it worked<br>
just fine (for the regular version).<br>
<br>
Now I want to try to build the emscripten version. I am looking at<br>
the instructions at<br>
<a href="https://sourceforge.net/p/reduce-algebra/code/HEAD/tree/trunk/csl/new-embedded/for-emscripten/">https://sourceforge.net/p/reduce-algebra/code/HEAD/tree/trunk/csl/new-embedded/for-emscripten/</a><br>
that are linked from<br>
<a href="https://reduce-algebra.sourceforge.io/web-reduce/about.php?start">https://reduce-algebra.sourceforge.io/web-reduce/about.php?start</a> as<br>
"for details of how to build this version of REDUCE". But whenever I<br>
run any of the 'make' commands I get errors like<br>
<br>
make: *** No rule to make target 'allocate.o', needed by 'reduce.js'. Stop.<br>
<br>
I know you said that isn't your corner of the project, but maybe<br>
someone else can help me with this?<br>
