Sorry to bother with a beginner question. I am following the basic tutorial at https://www.kodymirus.cz/tex4ht-doc/BasicTutorial.html#basic-tutorial. I download a clean copy of my project from https://gitlab.com/jim.hefferon/toc. I check that it compiles with make. Then based on the tutorial I ran make4ht book.tex and got this.
jim@millstone:~/src/computing/src$ make4ht book.tex [STATUS] make4ht: Conversion started [STATUS] make4ht: Input file: book.tex [ERROR] htlatex: Compilation errors in the htlatex run [ERROR] htlatex: Filename Line Message [ERROR] htlatex: ? 26 Package biblatex Error: Patching 'endnotes' package failed. [ERROR] htlatex: ? 28 TeX capacity exceeded, sorry [input stack size=10000]. [FATAL] make4ht-lib: Fatal error. Command htlatex returned exit code 1 I don't see any .log file or any other idea where to start debugging. No doubt I've missed what to do. I have just today updated my TeX LIve, and I have a copy of endnotes.sty. The book is 160K lines of LaTeX and I certainly did not expect it to run without a hitch, but where do I start in to try to figure out what to adjust?
