trying to compile packages from source, but lacking /opt/local/bin/gcc-mp-5

%vjcair> R CMD config CC

/opt/local/bin/gcc-mp-5


I don't seem to be able to override this using environment variable CC.  And

I cannot see how to install gcc-mp-5.  This version of R was obtained from

r.research.att.com, R-3.4-branch-el-capitan.pkg.


I would have expected clang to be the c compiler for this build.  I will

appreciate any suggestions.  As it stands, any installation from source
requiring

compilation throws errors like

/bin/sh: /opt/local/bin/g++-mp-5: No such file or directory

It was for the released version of 3.4.2.  Problems with off-CRAN builds 
are best addressed to the builder, here Simon Urbanek.  But that is a 
month-old snapshot build ... I don't understand why you did not simply 
update it, and I see 'clang' in the current snapshot.

Yes, section 6.3.3. gives the solution.
Without alternate settings in the platform-specific Makevars, the most
recent binary gives the value of "R CMD config CC" noted in the original
posting.

Thank you for your assistance.

Vince,

I'm pretty sure you are using custom settings, because the binary uses clang:

$ R CMD config CC
clang
$ grep -r /opt/local/bin/ /Library/Frameworks/R.framework/
$ 

We don't have /opt/local on the build machine so it must be something configured in your system.
Please make sure you don't use custom package managers on you PATH since you'd be picking up non-CRAN R.

Cheers,
Simon

Of course -- there were forgotten settings in $HOME/.R/Makevars -- I should
have inferred that it was a private matter.  Apologies.
