[R-pkg-devel] what is difference between Mac setup of rhub and CRAN

[Gábor Csárdi]

The R-hub macOS machine is also 10.11.6, and has XCode 8.2.1, but does
not use the CRAN clang 4.0.0 compiler currently. Seems like your
package has compiled code, so this _might_ matter. Sometimes there are
issues when linking C++ libs produced by different compilers, because
the ABIs can be slightly different. E.g. exceptions are sometimes lost
between compilation units. So if you are linking to a system library
that was compiled with the standard macOS compiler, then this can come
up. I suggest you download the clang compiler from CRAN and try to
reproduce it locally.

Best,
Gabor
