Because clang is the default compiler for R on MacOS. So you would make it difficult for other people (let alone CRAN) to make use of the package. However, I think there is something wrong about your macOS machine. I have just tried to compile your package on a macOS machine that I have access to, and I got quite different results: $ R CMD INSTALL bambi_1.0.tar.gz * installing to library ‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library’ * installing *source* package ‘bambi’ ... ** libs /usr/local/clang4/bin/clang++ -std=gnu++11 -I/Library/Frameworks/R.framework/Resources/include -DNDEBUG -I../inst/include/ -I"/Library/Frameworks/R.framework/Versions/3.4/Resources/library/Rcpp/include" -I/usr/local/include -fPIC -Wall -g -O2 -c RcppExports.cpp -o RcppExports.o /usr/local/clang4/bin/clang++ -std=gnu++11 -I/Library/Frameworks/R.framework/Resources/include -DNDEBUG -I../inst/include/ -I"/Library/Frameworks/R.framework/Versions/3.4/Resources/library/Rcpp/include" -I/usr/local/include -fPIC -Wall -g -O2 -c bambi.cpp -o bambi.o bambi.cpp:7:14: fatal error: 'bam_lmdb.h' file not found #include "bam_lmdb.h" ^~~~~~~~~~~~ 1 error generated. make: *** [bambi.o] Error 1 ERROR: compilation failed for package ‘bambi’ * removing ‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library/bambi’ I had not installed the necessary C library, so unsurprisingly the compilation step already failed. What I find interesting is that in my case "-std=gnu++11“ and "-I../inst/include/" are present in the command line options for clang++. These are also missing from what you quoted and are also a consequence of src/Makevars. It almost looks as if this file got lost on your macOS box … Greetings Ralf _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
