devEMF package in R 3.5 on macOS doesn't build

Question

I'm trying to install and build from source the package devEMF but it doesn't build. I've tried to install on macOS 10.11.6 and 10.13.4 with the same exact result. In both system I have a R install with Homebrew.

Any idea about what could be the problem?

Thanks!

Answer 1

A recent change in some combination of clang / OSX CoreText API / R exposed a bug in the devEMF package, whereby it relied on an "int" data type being automatically cast to an "enum" data type.

devEMF version 3.6-1 fixes this bug by directly using the appropriate enum constant.

Answer 2

Ok! I figured it out! Seems that the problem was the makevars.

This is my makevars file

# Remove the comment on -fopenmp for compiling data.table package
CC=/usr/local/opt/llvm/bin/clang #-fopenmp
CXX=/usr/local/opt/llvm/bin/clang++ #-fopenmp
# -O3 should be faster than -O2 (default) level optimisation ..
CFLAGS=-g -O3 -Wall -pedantic -std=gnu99 -mtune=native -pipe
CXXFLAGS=-g -O3 -Wall -pedantic -std=c++11 -mtune=native -pipe
LDFLAGS=-L/usr/local/opt/gettext/lib -L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib
CPPFLAGS=-I/usr/local/opt/gettext/include -I/usr/local/opt/llvm/include

I commented all lines and installed it perfectly. Perhaps it isn't compatible with LLVM. I don't know.
