If you use TeX Live 2015 or up-to date Miktex distributions, make4ht should be installed already on your system.
You need to install it only if you use older distribution or try new features which aren't accessible in the version
included in the distributions.
You need a teX distribution such as TeX Live or Miktex. It must include tex4ht system, Noto fonts and texlua script. All modern
distributions include it. You also need Pandoc in order to make the documentation and
latexmk, which should be included in your TeX distro.
Run these commands:
make
make install
make4ht is installed to /usr/local/bin directory by default. The
directory can be changed by passing it's location to the BIN_DIR variable:
make install BIN_DIR=~/.local/bin/
See a guide by Volker Gottwald on how
to install make4ht and tex4ebook.
Create a batch file for make4ht somewhere in the path:
texlua "C:\full\path\to\make4ht" %*
you can find directories in the path with
path
command, or you can create new directory and add it to the path.
Note for Miktex users: you may need to create texmf directory first. See
this answer on TeX.sx.
If you get the following error message:
latexmk -lualatex make4ht-doc.tex
Latexmk: -lualatex bad option
Latexmk: Bad options specified
Use
latexmk -help
to get usage information
make: *** [make4ht-doc.pdf] Error 10
then you have old version of latexmk. Try to replace line:
latexmk -lualatex make4ht-doc.tex
in the Makefile with
lualatex make4ht-doc.tex
lualatex make4ht-doc.tex
latexmk takes care of correct number of compilations needed to produce the correct document.
If you get following error message:
/usr/local/bin/make4ht:5: module 'make4ht-lib' not found:
no field package.preload['make4ht-lib']
[kpse lua searcher] file not found: 'make4ht-lib'
[kpse C searcher] file not found: 'make4ht-lib'
then try to run command
texhash
this will update the TeX file database and newly installed files should be usable.
