Compile given source files so that they can subsequently be collected
into a shared object using
R CMD SHLIB or an executable
R CMD LINK.
A list of the names of source files to be compiled. Currently, C, C++, Objective C, Objective C++ and Fortran are supported; the corresponding files should have the extensions ‘.c’, ‘.cc’ (or ‘.cpp’), ‘.m’, ‘.mm’ (or ‘.M’), ‘.f’ and ‘.f90’ or ‘.f95’, respectively.
A list of compile-relevant settings, or for obtaining information about usage and version of the utility.
R CMD SHLIB can both compile and link files into a
shared object: since it knows what run-time libraries are needed
when passed C++, Fortran and Objective C(++) sources, passing source
R CMD SHLIB is more reliable.
Ratfor is not supported. If you have Ratfor source code, you need to convert it to FORTRAN. (On some Solaris systems mixing Ratfor and FORTRAN code will work.)
Objective C and Objective C++ support is optional and will work only if the corresponding compilers were available at R configure time: their main usage is on macOS.
Compilation arranges to include the paths to the R public C/C++ headers.
As this compiles code suitable for incorporation into a shared object, it generates PIC code: that might occasionally be undesirable for the main code of an executable program.
This is a
make-based facility, so will not compile a source file
if a newer corresponding ‘.o’ file is present.
Some binary distributions of R have
