Processing of single chapter files is ok.
In my productfile I have:
\startproduct kniha
\component kap01
\component kap02
\stopproduct
Of course, I have both chapters saved like kap01.tex...
I have that directory structure:
\Pes\environ.tex
\Pes\kap01\kap01.tex
\Pes\kap02\kap02.tex
\Pes\kniha\kniha.tex – this is the product file.
But when I try to process the product file, it saves kniha.log, kniha.tuc but no pdf file. Interesting is, the console says exactly:
mkiv lua stats > result saved in file - kniha.pdf
But no, it really doesn't save anything…
