~/.R/Makevars ignored during installation

[bearloga]

As I mentioned in #119, I was installing the package and noticed that it was using clang++ as the compiler:

* installing *source* package ‘httpuv’ ...
** libs
clang++ -std=gnu++11 -I/Library/Frameworks/R.framework/Resources/include -DNDEBUG -I./libuv/include -I./http-parser -I./sha1 -I./base64  -I"/Users/mpopov/Library/R/3.4/library/Rcpp/include" -I"/Users/mpopov/Library/R/3.4/library/BH/include" -I"/Users/mpopov/Library/R/3.4/library/later/include" -I/usr/local/include   -fPIC  -Wall -g -O2 -c RcppExports-legacy.cpp -o RcppExports-legacy.o
...
clang++ -std=gnu++11 -I/Library/Frameworks/R.framework/Resources/include -DNDEBUG -I./libuv/include -I./http-parser -I./sha1 -I./base64  -I"/Users/mpopov/Library/R/3.4/library/Rcpp/include" -I"/Users/mpopov/Library/R/3.4/library/BH/include" -I"/Users/mpopov/Library/R/3.4/library/later/include" -I/usr/local/include   -fPIC  -Wall -g -O2 -c websockets.cpp -o websockets.o
cp -p -f libuv/m4/lt_obsolete.m4 libuv/m4/lt~obsolete.m4
(cd libuv \
		&& touch Makefile.in aclocal.m4 configure m4/lt~obsolete.m4 \
		&& CC="gcc-7" CFLAGS="-Wall -g -O2  -fPIC " AR="ar" RANLIB="ranlib" LDFLAGS="-L/usr/local/lib" ./configure )
checking for a BSD-compatible install... /usr/bin/install -c
...

even though my ~/.R/Makevars includes the following:

VER=-7
CC=gcc${VER}
CXX=g++${VER}
CXX1X=g++${VER}
FC=gfortran${VER}
F77=gfortran${VER}
MAKE=make -j4

I'm not sure how problematic or deliberate this actually is, so please feel free to close the issue if this is by design.

Thanks!

I think you need to set CXX11.

See the Makeconf file for all the default settings. On a Mac, it's usually at: /Library/Frameworks/R.framework/Resources/etc/Makeconf

[bearloga]

You were correct and thank you so much for the pointer!

@bearloga Anyway you can direct my setting of CXX11? In checking my Makeconf I have this:
kingkong:etc fjlicht$ head Makeconf
#etc/Makeconf. Generated from Makeconf.in by configure.

#${R_HOME}/etc/Makeconf

#R was configured using the following call
#(not including env. vars and site configuration)
#configure 'CC=clang' 'CXX=clang++' 'OBJC=clang' 'CFLAGS=-Wall -g -O2' 'CXXFLAGS=-Wall -g -O2' 'OBJCFLAGS=-Wall -g -O2' 'FCFLAGS=-Wall -g -O2' 'F77FLAGS=-Wall -g -O2' '--enable-memory-profiling' '--x-libraries=/opt/X11/lib' '--enable-R-framework' 'PKG_CONFIG_PATH=/usr/lib/pkgconfig:/opt/X11/lib/pkgconfig:/usr/local/lib/pkgconfig'

##This fails if it contains spaces, or if it is quoted
include $(R_SHARE_DIR)/make/vars.mk

Any help would be appreciated.

@fjlicht: did you happen to install R with Homebrew or MacPorts, rather than downloading the binary from https://cran.r-project.org/bin/macosx/

[fjlicht]

@bearloga I believe that I downloaded and installed the binary. I have since transitioned to another comp/system and can not check back to where I was last year. Thank you for investigating, I can try and pull it up if I get a moment later this week, if that would be of help?
