"Failed to locate the 'texi2pdf' output file"

Just thought I would mention that the issue below (and in https://stat.ethz.ch/pipermail/r-devel/2013-April/066318.html) is still not resolved.

It hasn't been a big problem, but it potentially could be, if a critical package were to have this error on release day, then all its dependencies would fail to build, which would probably require us to postpone our release.

See the complete thread (link above) for followup posts which establish that this has nothing to do with databases, sockets, or virus scanners, and occurs even in packages that have no dependencies or R code in them. The post below from Henrik points to a possible cause.

Thanks,
Dan

Dan,

This error looks _very_ similar to what I reported regarding the use of
'foreach' inside a windows vignette, on the bioc-devel email list.  As you
say, it looks funny that it lists the tex file, yet fails to find it.

It's not looking for the TeX file, but the PDF file - that is what the
error message is referring to by "Failed to locate the 'texi2pdf'
output file".  [ Note that in this error message I use the term
"vignette" in a conceptual sense, not necessarily the vignette
*source* file (here *.Rnw) - maybe that is what is confusing. ]
Immediately after calling tools::texi2pdf("OrganismDbi.tex"), the code
tries to locate the texi2pdf output file, that is, 'OrganismDbi.pdf',
which it cannot find.  This indicates that tools::texi2pdf() gave an
error (an error message which is currently not reported/available),
which in turn indicates that the 'OrganismDbi.tex' file is
corrupt/incomplete.

The issue had to do with closing relevant connections (for foreach, this
was a Windows issue because the default foreach backend on Windows uses
connections).   For my particular case, solving it was a bit difficult
because I could not just close all connections since a vignette is being
run inside sink().

The package name makes me suspect a database connection. As a starting
point I suggest closing all existing connections in the vignette.

I think it's worth looking into what Kasper says - that's hopefully the reason.

PS. I do find it odd that these issues starting to occur now, because
most of the vignette framework is performing the same steps as in R (<
3.0.0).  The main difference is see is that it now validates/asserts
that the expected output file is there *immediately* after trying to
generate them (using weave, tangle, and texi2pdf).  If for some reason
texi2pdf generates the PDF in a background process which is not
completed in full when returning the control to R, then the PDF is not
there and you would get this error.  I don't know if this can happen.
The reason why I came to think of this is because I recall that I've
seen this behavior when using bitmap() and Ghostscript to create PNGs.
 Just a shot from the hip, though.

Hi,
Every day a few Bioconductor packages (different ones each day) fail
to build, on Windows only, with an error like this:

D:\biocbld\bbs-2.13-bioc\meat>D:\biocbld\bbs-2.13-bioc\R\bin\R.exe CMD
build --keep-empty-dirs --no-resave-data OrganismDbi
[...]
Error in find_vignette_product(name, by = "texi2pdf", engine = engine) :
  Failed to locate the 'texi2pdf' output file (by engine

files exists in directory '.': 'OrganismDbi.Rnw', 'OrganismDbi.tex',
'databaseTypes.pdf'
Calls: <Anonymous> -> find_vignette_product

This is puzzling to me because I would have thought that
'OrganismDbi.tex' was the file it was looking for, yet it says that
file exists.

These build errors are transient...if I re-run the build, the error
does not recur. So I was hesitant to report the problem because can't
be reproduced consistently. Nevertheless it is a problem.
