| I dug a little bit deeper and found the following: the Perl module
| XML::DOM::Parser extends the module XML::Parser, which uses the expat
| library (package libexpat1 in Debian). The error that Joao gets:
| undefined entity at line 2915, column 62, byte 85921 at
| line 185
| comes for the expat library (I am 100% sure about this). What is
| intriguing is that the expat library have different behaviors in
| Joao's system than in Debian. However, I could replicate the bug
| above when I changed the first line of src/plplotdoc.xml.in to:
| <?xml version="1.0" standalone="yes"?>
| The standalone declaration tells the parser that the document has no
| external definitions. It seems that Joao system's expat library is
| assuming this.
| I did a commit recently that may fix this problem. I added an
| explicit declaration standalone="yes" to the temporary file that is
| parsed by api2txt.pl, which is a "concatenation" of plplotdoc.xml.in
| (yes, Alan, *.in!) and api.xml. I also added "text" definition for
| the entities usually found in api.xml. The nice side-effect of this
| change is that, contrary to what happened before, the output in the
| *.txt is correct, with entities like "°", ">", and "–"
| being translated into " degrees", ">", and "--", respectively.
| Test this, please.
Yes, it works. And also in a straight RH-8.0 from a colleague. And also
in a plain SuSE-8.1 from another colleague.
| When I will have some time, I will commit the change in
