This is probably a conda issue instead of Rccp itself, but maybe someone has ideas on what to do about it. I've installed R via conda: r-base v3.4.1 from the "r" channel. When trying to install Rccp (or any packages depending on Rccp) with install.packages(), I get the error:

/ebio/abt3_projects/software/dev/miniconda3/envs/test/bin/x86_64-conda_cos6-linux-gnu-c++  -I/ebio/abt3_projects/software/dev/miniconda3/envs/test/lib/R/include -DNDEBUG -I../inst/include/  -D_FORTIFY_SOURCE=2 -O2 -I/ebio/abt3_projects/software/dev/miniconda3/envs/test/include   -fpic  -fvisibility-inlines-hidden  -fmessage-length=0 -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -pipe -I/ebio/abt3_projects/software/dev/miniconda3/envs/test/include  -c Date.cpp -o Date.o

/ebio/abt3_projects/software/dev/miniconda3/envs/test/lib/R/etc/Makeconf:167: recipe for target 'Date.o' failed

I've tried conda install gcc_linux-64, but this doesn't install x86_64-conda_cos6-linux-gnu-c++. The closest file to this is "x86_64-conda_cos6-linux-gnu-c++filt", and symlinking this as "x86_64-conda_cos6-linux-gnu-c++" doesn't work.

Is there a way to bypass using x86_64-conda_cos6-linux-gnu-c++?

I've tried the suggestions at this post on stackoverflow, but nothing's working. I don't want to abandon using conda environments, but I can't install all the R packages I need via conda (eg., the "r" or "bioconda" channels), and installing packages with install.packages() keeps generating x86_64-conda_cos6-linux-gnu-c++: command not found errors for certain R packages.
