RcppEigen.h：在Centos 7上安装…RcppEigen的过程中没有此类文件或目录

Question

I'm not new to R but can't figure out what went wrong. I'm just trying to install RcppEigen package using install.packages('RcppEigen') and receive the above error.

The command below (issued by the installer) fails:

 g++ -m64  -I/usr/include/R -DNDEBUG  -I"/usr/lib64/R/library/Rcpp/include" -I/usr/local/include  -std=c++11 -fpic  -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches   -m64 -mtune=generic  -c RcppEigen.cpp -o RcppEigen.o

I have installed both R-Rcpp and R-Rcpp-devel version 0.12.12 from EPEL repository as well as eigen3-devel v 3.2.5 (not sure whether it is required but anyway ...)

I cloned RcppEigen from Github and tried to build in RStudio - the same error.

Makevars has PKG_CXXFLAGS = -I../inst/include but the compiler is invoked as below:

g++ -m64  -I/usr/include/R -DNDEBUG  -I"/home/zer0hedge/R/x86_64-redhat-linux-gnu-library/3.4/Rcpp/include" -I/usr/local/include  -std=c++11 -fpic  -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches   -m64 -mtune=generic  -c RcppEigen.cpp -o RcppEigen.o

Answer 1

For some reason, I had PKG_CXXFLAGS defined in $HOME/.R/Makevars . It erroneously overrided PKG_CXXFLAGS in Makevars in src directory of the package and prevented compilation of C++ files
