Hi,
I have R version 2.8.1 and Rtools 28 installed (as you might guess, set up
years ago). In Rtools the MinGW GCC 4.2 compiler toolset is included.
For my regular C/C++ programs I have also installed, separately, the full
MinGW bundle with the latest GCC 4.5 compiler tools. So I have two g++
variants on the same machine.
According to the Rtools documentation, the bin directory of it shall be in
the system PATH, and very early in the PATH (first elements). Presently the
bin directory of the Rtools-MinGW is front.
Fine but Ok for my daily C++ work I actually prefer that the regular
(non-Rtools) MinGW compiler is invoked, hence I would prefer putting that in
front. But then, of course, invoking g++ from R development would refer to
the regular MinGW compiler toolset. When I do R development, would you expect
it to cause problems if actually the regular MinGW (gcc 4.5) is invoked, and
not the version that came bundled with Rtools (4.2) ? Or is this something I
should better stay away from ?
If not likely to work, what would you suggest to do instead ?
Follow the posting guide and update your R before posting ....
We do not support ancient versions of R, and it is very likely that R
2.8.1 does not work correctly with gcc 4.5.2: there are
incompatibilities in the argument passing.
thanks and best,
Thomas
