Compilation of R #4

Closed pbroser closed 2 years ago

pbroser commented 2 years ago

Dear Eric Dunipace,

When I am trying to use the hilbertSort.cpp with the R commands:

library(RcppCGAL) Sys.setenv("CGAL_DIR" = "/opt/homebrew/Cellar/cgal/5.4.1/include") Rcpp::sourceCpp("hilbertSort.cpp")

I get the following error:

"R.framework/Versions/4.2-arm64/Resources/library/RcppCGAL/include/CGAL/config.h:128:10: fatal error: 'boost/config.hpp' file not found"

Even when I am using the homebrew Cgal Version with R I get the same error library(RcppCGAL) Sys.setenv("CGAL_DIR" = "/opt/homebrew/Cellar/cgal/5.4.1/include") Rcpp::sourceCpp("hilbertSort.cpp")

Any idea how to fix this?

Many Greetings

Philip

Hi Philip,

Thanks for highlighting this. Have you tried attaching the boost headers package in R? From the warning, it looks like the header files are trying to find a boost library on your system and cannot.

Let me know if that works, and I will update the readme file accordingly.

Hey,

I just updated my R to 4.2 and got the same error you did. I modified the code in the readme file so include the appropriate R packages. That should work but if it doesn't, let me know!

Thanks again for bringing this to my attention!

Dear Eric,

Thanks for your reply, I still get the following error when I am trying to compile the hilbert sort.cpp given in the readme file: /Library/Frameworks/R.framework/Versions/4.2-arm64/Resources/library/RcppCGAL/include/CGAL/config.h:128:10: fatal error: 'boost/config.hpp' file not found

include <boost/config.hpp>

     ^~~~~~~~~~~~~~~~~~

18 warnings and 1 error generated. make: *** [HilbertSort.o] Error 1 Fehler in Rcpp::sourceCpp("HilbertSort.cpp") : Error 1 occurred building shared library.

I will send you the cpp and R file I am susing. What I realized that in the boos directory has no config.h.

My terminal shows:

(base) @. CGAL % pwd /Library/Frameworks/R.framework/Versions/4.2-arm64/Resources/library/RcppCGAL/include/CGAL (base) @. CGAL % cd boost (base) @. boost % ls bimap bimap.hpp graph iterator parameter.h (base) @. boost %

I tryed to redictrect R to my CGAL homebrew installation with

Sys.setenv("CGAL_DIR" = "/opt/homebrew/opt/cgal")

Sys.setenv("BOOST_DIR" = "/opt/homebrew/opt/boost") <- doest not change anythinkg

but the package still used the CGAL installation of R.

See attached R script and the cpp File.

Greetings

Philip

You’re looking at the boost folder in CGAL, not the boost library. Do you have boost installed or the BH header files loaded?

Part of the problem with trying to use your home-brew is that the Github version already comes installed with CGAL so the package will ignore your variable telling it to use your library. The one included in the package is better to use if you’re building and submitting other R packages as it has some hacky code to make it acceptable to CRAN maintainers.
