Installing packages in R Code Environment (Conda-forge?)

tgb417

Using Macintosh with High Sierra (10.13.5)

I'm trying to install the following packages into a Code Env and having difficulties.

• deSolve
• flexsurv
• muhaz

If I use Conda to do this. DSS can't find the packages. (Makes sense, they are not in the "standard" list of conda packages)

If I Request the R package directly in the Code Envs setup I'm getting a compilation error.

ld: warning: directory not found for option '-L/opt/conda/conda-bld/r-base_1519528683708/_build_env/lib/gcc/x86_64-apple-darwin11.4.2/4.8.5'
ld: warning: directory not found for option '-L/opt/conda/conda-bld/r-base_1519528683708/_build_env/lib/gcc'
ld: warning: directory not found for option '-L/opt/conda/conda-bld/r-base_1519528683708/_build_env/lib'
ld: library not found for -lquadmath
clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [muhaz.so] Error 1
ERROR: compilation failed for package ‘muhaz’

This happens even though I've had no problems installing with RStudio installed compiling the same packages. (My guess is that I have some sort of path not set in the DSS environment.

Questions:

• Can one use conda-forge package with DSS? Some of what I'm looking for is there.
• Anyone work through a situation like the above with this kind of compilation issue?

Hi,

You can use conda-forge by adding options for the "conda" command. In your code env settings, uncheck "inherit global settings", and add "-c" and "conda-forge" as options. Beware that conda-forge very often causes incompatibilities with other packages, though



Your compilation issue comes from the fact that you don't have the libquadmath development headers, which is required in order to compile code using it. It may be possible to install this via brew

Clément thanks so much for the quick reply.

There are two options when one unchecks "Inherit global settings
* Extra options for 'conda create'
* Extra options for 'conda install'

I presume you are referencing the second option 'conda install'.

It seems a bit odd that you need two lines one for each of the parameters. I'm not clear if I need the double quotes or not. And the reference documentation is not clear on this point regarding this page. I've tried both and did not achieve a successful install.

Looks like there were a bunch of other prerequisites that were being attempted to be installed.

```Updating code environment according to spec ...

These R packages install just fine on my non-anaconda RStudio on the same machine. What I'm not clear about is what is the best way to get conda to install the library libquadmath. Or have DSS reference the library in my non-anaconda environment.

I've tried installing
gcc
libgcc
mkl
mpmath

from conda.

libgcc seems to include a libquadmath.0.dylib file.
