Hello again, Chris, thanks for the fast response to my previous post. That kind of responsiveness can only lead to one thing: more bug reports and requests! Here's one. According to the tutorial (Section 3.3 Building GiNaC), I can build the documentation with "make" commands such as $ make html $ make pdf Here is what I get when I try this (using ginac version 1.3.4). I am running the "make" commands in the same directory where I just completed the usual "./configure" (with no options) and "make" commands. First I tried "make html": -------------------------------------------------------------------- $ make html make: *** No rule to make target `html'. Stop. -------------------------------------------------------------------- Next, "make pdf": -------------------------------------------------------------------- $ make pdf ... snip (lots of latex stuff) ... Output written on ginac.pdf (118 pages, 753760 bytes). Transcript written on ginac.log. make[2]: Leaving directory `/home/wweckesser/test_ginac_doc/ginac-1.3.4/doc/tutorial' Making pdf in reference make[2]: Entering directory `/home/wweckesser/test_ginac_doc/ginac-1.3.4/doc/reference' warning: target reference.pdf disabled by configuration This is pdfeTeX, Version 3.14159-1.10b-2.1 (Web2C 7.4.5) entering extended mode ! I can't find file `reference.tex'. <*> reference.tex Please type another input file name: --------------------------------------------------------------------- "make pdf" successfully builds the file ginac.pdf in doc/tutorial, but something goes wrong in doc/reference.
