The installation instructions do say to install Xcode but I just wonder why the command-line tools aren’t sufficient for PGI 17.10 on macOS. Is there no way to install PGI with just the CLI? Thanks!
PGI compilers don’t provide system headers, runtime libraries, and
linkers and (clang) ‘assemblers’. That comes from Xcode on OS X,
from Windows SDK on Windows, and from gcc on Linux.
It is a good practice, so we can be compatible with programs
compiled on other compilers.
Doesn’t all that come with the command-line tools, though? I have an entire compiler toolchain running and don’t have Xcode installed, exactly because I don’t need it.
Could you please clarify?
