Compilation fails - Githubissues

Hello Daniel,

I Seem to be having an issue on windows regarding the compilation of the package.

The error log is as follows:

> devtools::install()

I feel like the relevant line would be ...

:init.c:(.rdata+0x64): undefined reference to `Peptides_absoluteCharge'
init.o:init.c:(.rdata+0x70): undefined reference to `Peptides_chargeList'
init.o:init.c:(.rdata+0x7c): undefined reference to `Peptides_RcppExport_registerCCallable'

is there any particular compiler that would be required that I am not aware of ?

unfortunately , my knowledge of c/cpp is not enough to help with further debugging.

Kindest wishes, Sebastian
