I recently needed to install R 3.2 to get a package from Bioconductor working, but after I installed, I get the following error:
[16:16:11 20] $ r
dyld: Library not loaded: /usr/local/lib/gcc/4.9/libgfortran.3.dylib
Referenced from: /usr/local/Cellar/r/3.2.0/R.framework/Versions/3.2/Resources/lib/libR.dylib
Reason: image not found
Trace/BPT trap: 5
Sure enough, brew was set to use gcc 5, so I told brew to use the 4.9 version
brew switch gcc 4.9
which got R running, but then R would fail in the middle of a package install (specifically when I ran biocLite('DESeq2')
.
Since then, I have tried a number of things, including trying to install gcc 4.8 (but I can't seem to get R to use it, even via ~/.R/Makevars
). Even if 4.9 is not installed, R insists on calling the path shown above.
The windows version of R seems to say 4.9 does not work with 3.2:
R-devel temporarily used a new toolchain based on 4.9.2 gcc, put together by Duncan Murdoch using build scripts written by a contractor. However, there were too many incompatibilities with existing code, and this toolchain will not be used for R 3.2.0. See notes for details on building and testing the new toolchain.
Any help would be greatly appreciated!
Edit: I tried installing from source, as suggested by @lmw., but it fails:

GCC has been built with multilib support. Notably, OpenMP may not work:

If you need OpenMP support you may want to
brew reinstall gcc --without-multilib

Edit 2:
Just for the fun of it, I tried installing r
without the --build-from-source
option, and it worked. See my solution below. (I think building from source may have fixed the issue with the gcc 5
upgrade, which got things working. I am not going to try it (things are finally working again...why screw with it?), but I wonder if I could remove the variables I set in ~/.R/Makevars
(again, see solution below).
Rebuilding R from source fixes the same problem for me.
brew reinstall r --build-from-source
This was resolved by this commit, with new bottles for R. Make sure you brew update
and brew upgrade r
.
