Hi Folks,
I've recently transitioned to Debian 8.0 and was having a hard time
getting Rmpi to work.
I believed I'd successfully installed dependencies via
> sudo apt-get install r-cran-rmpi
> apt-show-versions r-cran-rmpi
r-cran-rmpi:amd64/jessie 0.6-5-1 uptodate
but when installing the package I was still getting
checking mpi.h presence... no
checking for mpi.h... no
configure: error: "Cannot find mpi.h header file"
ERROR: configuration failed for package ‘Rmpi’
I discovered that /usr/lib/openmpi/include/ was missing
In hindsight, it is obvious that header files are only included when the
dev version of openmpi is intalled:
> sudo apt-get install libopenmpi-dev
After which Rmpi package installed without error.
I'm not very familiar with debian package management, but wouldn't most
debian R users be building package from source? If so, maybe
libopenmpi-dev should be added as a dependency of r-cran-rmpi ? If not,
hopefully this post will help other users like me.
best,
-skye
