[R-pkg-devel] Problems with devtools::build() in R

[Jarrett Phillips]

Hi Ivan,

Yes, I can build a Fortran program successfully.

cat >hello.f90 <<EOF
program hello
 print *, 'Hello world'
end program
EOF
gfortran -o hello hello.f90 && ./hello

returns Hello world as expected.

`which gfortran`  returns

/usr/local/bin/gfortran



`gfortran -print-search-dirs` returns


install: /usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/

programs:
=/usr/local/gfortran/libexec/gcc/aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/libexec/gcc/aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/libexec/gcc/aarch64-apple-darwin22/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/../../../../aarch64-apple-darwin22/bin/aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/../../../../aarch64-apple-darwin22/bin/

libraries:
=/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/../../../../aarch64-apple-darwin22/lib/aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/../../../../aarch64-apple-darwin22/lib/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/../../../aarch64-apple-darwin22/12.2.0/:/usr/local/gfortran/lib/gcc/aarch64-apple-darwin22/12.2.0/../../../



file.path(R.home('etc'), 'Makeconf') in R returns


[1] "/Library/Frameworks/R.framework/Resources/etc/Makeconf"

Finally, yes, R CMD build fails for me bith through the Mac Terminal and
via devtools::build().


Cheers,

Jarrett
