see following example:

R is compiled and use the following CC and CFLAGS definition

bigmess:epactsR/src > R CMD config CC
gcc -std=gnu99
bigmess:epactsR/src > R CMD config CFLAGS
-Wall -g

so building C sources lead to the following

bigmess:epactsR/src > R CMD SHLIB index.c
gcc -std=gnu99 -I/local/gensoft2/adm/lib64/R/include -DNDEBUG
-I/usr/local/include-fpic  -Wall -g  -c index.c -o index.o

normal, it uses defintion from RHOME/etc/Makeconf


when I set upp a ~/.R/Makevars that overwrite CC and CFLAGS definition.

bigmess:epactsR/src > cat ~/.R/Makevars
CC=gcc
CFLAGS=-O3
bigmess:epactsR/src > R CMD SHLIB index.c
gcc -I/local/gensoft2/adm/lib64/R/include -DNDEBUG  -I/usr/local/include
   -fpic  -O3 -c index.c -o index.o
gcc -std=gnu99 -shared -L/usr/local/lib64 -o index.so index.o


OK CC and CFLAGS are honored and set accordingly to ~/.R/Makevars


but when I try to use src/Makevars, it is ignored

bigmess:epactsR/src > cat ~/.R/Makevars
cat: /home/edeveaud/.R/Makevars: No such file or directory
bigmess:epactsR/src > cat ./Makevars
CC = gcc
CFLAGS=-O3
bigmess:epactsR/src > R CMD SHLIB index.c
gcc -std=gnu99 -I/local/gensoft2/adm/lib64/R/include -DNDEBUG
-I/usr/local/include-fpic  -Wall -g  -c index.c -o index.o


what I have missed or is there something wrong ?


Use PKG_CFLAGS instead of CFLAGS; CC cannot be changed in Makevars. See 
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Using-Makevars

PS I tested the ssame behaviour with various version of R from R/2.15 to
R/3.3

[R] src/Makevars ignored ?

[Eric Deveaud]

Hello,

as far as I understood the R library generic compilation mechanism, 
compilation of C//C++ sources is controlde


1) at system level by the ocntentos RHOME/etc/Makeconf
2) at user level by the content of ~/.R/Makevars
3) at package level by the content of src/Makevars

Problem I have is that src/Makevars is ignored


see following example:

-Wall -g

so building C sources lead to the following

bigmess:epactsR/src > R CMD SHLIB index.c
gcc -std=gnu99 -I/local/gensoft2/adm/lib64/R/include -DNDEBUG 
-I/usr/local/include-fpic  -Wall -g  -c index.c -o index.o


normal, it uses defintion from RHOME/etc/Makeconf


when I set upp a ~/.R/Makevars that overwrite CC and CFLAGS definition.
