Building a texlive environment in Cygwin

[Drew Abbott]

Hi,

I am trying to set up texlive in Cygwin and installing the texlive
package seems to get me most of the way there. I tried to compile a
test document using the fontspec package (lualatex test.tex), but ran
into errors about a missing package (! LaTeX Error: File
`fontspec.sty' not found.). On my other machines, texlive seems to
download packages on its own, as needed. Is there further
configuration required? I could not find any guidance easily on
setting up a working environment in Cygwin.

Thanks,
Drew
