Tomek,
Fortran symbols are not included C headers (even though they are part of the
library) so probably the easiest is to add
-Wno-error=implicit-function-declaration.
However, if you just want to test Accelerate BLAS, use libRblas.vecLib.dylib,
because that is a simple re-export of the Accelerate framework - it doesn't
include any actual code:
$ otool -l /Library/Frameworks/R.framework/Resources/lib/libRblas.vecLib.dylib
| grep -A2 REEXPORT
cmd LC_REEXPORT_DYLIB
cmdsize 96
name
/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate (offset
24)
The blas00.c is just a dummy file to test the symbols R is using (without their
prototypes), but on macOS that doesn't even matter as we don't bind them at
compile time anyway so all symbols are re-exported instead.
Cheers,
Simon
