gsl error when trying to compile OpenABM-Covid19 R package on MacOS

[lampk]

Dear all,

I have followed instruction to compile R package but haven't successful yet. I have installed gsl 2.71 through brew, swig@3.0.12, and successfully build R/OpenABMCovid19.R and src/covid19_wrap_R.c. However, I cannot build or install the package and the error seems to relate to 'gsl/gsl_rng.h' not found.

I have tried 3 different computers using MacOS and they all produced errors related to "gsl_rng.h" (MacBook Pro M1 - Big Sur - R version 4.0.4, MacBook Pro Intel - Big Sur - R version 4.0.1, iMac - Catalina - R version 4.1.0)

Below are errors when I used MacBook Pro M1, OS Big Sur, R version 4.0.4., and tried devtools::document(), or devtools::build():

Error: Could not find tools necessary to compile a package Call pkgbuild::check_build_tools(debug = TRUE) to diagnose the problem.

Below is error when I tried R CMD INSTALL --no-multiarch --with-keep.source OpenABM-Covid19-master:

• installing to library ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library’
• installing source package ‘OpenABMCovid19’ ... using staged installation libs clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I/usr/local/include -fPIC -I/usr/local/opt/gsl/include -c R_C_interface.c -o R_C_interface.o In file included from R_C_interface.c:7: In file included from ./model.h:17: In file included from ./individual.h:16: In file included from ./params.h:11: ./constant.h:11:10: fatal error: 'gsl/gsl_rng.h' file not found

This issue is due to mis-specification of path to gsl in the Makevars file. After correct gsl path in the Makevars, the compilation works fine.
