Dear bioconductor team,

When I try to run the msPurity package on R (which is using the XCMS package) I run in the following warning message:

Warning message:
In fun(libname, pkgname) :
  mzR has been built against a different Rcpp version (0.12.8)
than is installed on your system (0.12.11). This might lead to errors
when loading mzR. If you encounter such issues, please send a report,
including the output of sessionInfo() to the Bioc support forum at 
https://support.bioconductor.org/. For details see also
https://github.com/sneumann/mzR/wiki/mzR-Rcpp-compiler-linker-issue.

I already tried to solve them according to the instructions on "

https://github.com/sneumann/mzR/wiki/mzR-Rcpp-compiler-linker-issue" but it did not help. 

Here is also the sessionInfo which was mentioned in the warning message (hope I understood that right):

Do you know if there is a way to solve this problem or do I have to give you more information on it first? Anyway many thanks for your help in advance!

What you see is a warning that highlights the version mismatch. In most cases, it can be ignored and everything will work as expected. In the past, when Rcpp had more substantial changes, error happened. If this happens, please report back. Otherwise, enjoy mzR and msPurity.
