That's usually ok.

But apparently not in this case :)
/*
While I try to build the package, a quick note from IRC for upstream:
I'd say https://bugs.debian.org/810017 was just asking for it:
https://sources.debian.net/src/psi4/1:0.3-4/doc/sphinxman/document_options_c.pl/#L6
*/
Ok, after some debugging (and guessing what the code tries to do,
which is not very obviuous to me):
The second error arises when
$Module = 'SCF' and $Subsection = 'Parallel Runtime', and indeed,
Data::Dumper'ing %hash shows:
$VAR35 = 'SCF';
$VAR36 = {
'DFSCF Algorithm ' => {
and all kind of other "subsections" but no "Parallel Runtime".
What works (as in: the build finishes and there are no errors or
warnings in this part) and is maybe not completely off and against
the author's intentions is to test for the existence of the specific
"subsection" hash key with:
- if (defined(%{$hash{$Module}{$Subsection}})) {
+ if (exists($hash{$Module}{$Subsection})) {
(Discussing this with upstream to make sure it does what it's
supposed to might be a good idea. And to fix this for everybody not
just for Debian of course. But for now it might be better than a
failing build.)
Cheers,
gregor
