LaTeX compilation failures

[khinsen]

The make pdf step fails for several reason.

First, there are duplicated backslashes in several of the generated files. I patched two files (see below), which seems to fix all these issues. But then I get another error message that I don't see how to fix:

! Undefined control sequence.

Ah - the macro \SupplementalLastPage is defined at the end of a run, on the last page. Next time the page footer gives the page number and the total number of pages. If there is no .aux file, that failed.

Now changed so that the footer is conditional: if \SupplementalLastPage is not defined, there is a warning rather than a failure; if \SupplementalLastPage is defined, its value is used. The alternative would be to interactively type r to TeX to ignore the error - but of course that also ignores any other errors and therefore isn't as safe as this solution.

thanks for all your work.

This problem happened [past tense:-] because the macro \SupplementalLastPage was defined at the end of a run, on the last page. Next time the page footer then gives the page number and the total number of pages.

However, if there is no .aux file - or if there has been any early termination of the Latex run so \SupplementalLastPage never gets to typeset the last page - the idea failed.

Now fixed so that the footer is conditional, so if \SupplementalLastPage is not defined, there is a warning rather than a failure; or if \SupplementalLastPage is defined, its value is used.

The alternative - which I'd been using without thinking - was to interactively type r to TeX to ignore the error, so that the run completes and \SupplementalLastPage gets defined - but of course that also ignores any other errors and therefore isn't as robust as this new solution.

best,

Harold
