[Bioc-devel] octad.db check windows i386 not enough memory

[Hervé Pagès]

Hi Evgenii,

A process cannot allocate more than 3Gb of memory on 32-bit Windows so 
it looks like the process running the runsRGES() examples is hitting 
that limit. What doesn't help is that 'R CMD check' concatenates all the 
examples from all the man pages into a single file before running the 
code from this file so even if a particular example doesn't require a 
lot of memory it could fail because other examples before it created big 
objects that are sticking around.

The good news is that you're submitting a package for inclusion to the 
next version of Bioconductor (BioC 3.15) and we're going to drop support 
for 32-bit Windows for this new version. That's because BioC 3.15 will 
be based on R 4.2 which will also drop support for 32-bit Windows.

In the mean time, you should be able to disable the 32-bit checks by 
adding a .BBSoptions file in the top-level folder of your package. With 
the following line in it:

UnsupportedPlatforms: win32

I don't know if the SPB (Single Package Builder) will recognize this but 
it's worth the try.

Cheers,
H.
