[R-pkg-devel] DLL requires the use of native symbols

[Ivan Krylov]

Dear Simon,

Could you please look into this? The machines running r-release-macos-*
checks seem to have MassSpecWavelet < 1.66 installed instead of the
current version, 1.68. I think that MassSpecWavelet >= 1.66 would be
version-appropriate for R-4.3 (Bioconductor >= 3.17).

Interesting. It's not you, it's the MassSpecWavelet package, but the
error has already been fixed there. Look at the traceback produced for
the error:

>> Error in localMaximumSlidingWindow(x, winSize) :
>>  DLL requires the use of native symbols
>> Calls: MPC_DANM ... getLocalMaximumCWT -> localMaximum ->
>>        localMaximumSlidingWindow

The error happens in a function called 'localMaximumSlidingWindow',
called from 'localMaximum', called from 'getLocalMaximumCWT'.
'getLocalMaximumCWT' belongs to the MassSpecWavelet package.

The problem is that the maintainer sets R_forceSymbols(info, TRUE)
but then uses .Call() with a string containing the name of the function
instead of a special object that directly refers to that function. The
fix for that has been committed half a year ago
<https://code.bioconductor.org/browse/MassSpecWavelet/commit/496de2969b2f43f8be00f1966611497fa3053937>
and became part of the 1.66.0 release and the following versions of the
package. The fixed package versions went into Bioconductor 3.17 (for
R-4.3) but not 3.16 (for R-4.2).
