The issue is the .so and .o files are only viable with the same architecture e.g. OS X is 64 bit and Windows is 32bit (mingw_32). Please remove them from dev-1/src and then you should be good to go. These files are automatically built on package install as they are the result of using a compiler.

After they are removed, try to create a .gitignore file with the following:

src/*.o
src/*.so
src/*.dll

This will make OS specific files not selectable for staging and, in turn, commits.

As a general rule of thumb, only keep .cpp or .h files within /src while using Rcpp.
