Re: [Texmacs-dev] TeXmacs & Webassembly

[Massimiliano Gubinelli]

I'm not sure I understand the log correctly. Which page have you requested? It 
seems is not finding the files but it is strange since in this case it should 
not request for qtloader.js or the others.

The files TeXmacs.* have to be right in the directory where you invoke the 
python script (i.e. in $PWD). And then you visit http://localhost:TeXmacs.html 
in the browser.
