Hi Cesar,

This might be another reason for you to consider compiling on your ARM system.

The R programs (like 3dMVM) are scripts that run R and load our compiled R_io.so library for dataset I/O. That version of AFNI has R_io.so linked to an Intel version of the build machine's R library.

But since 3dMVM is a script, in your case it is running an ARM version of R, and that is refusing to load Intel shared libraries. In order to use R_io.so, you would need to be running an Intel version of R.

Given that, the R version itself, and difficulty with our signing the complete package, you should probably consider compiling AFNI locally on an ARM mac.

Unfortunately, someone (with my initials) has not written convenient build scripts, and some are looking into the possibility of making a brew package, which has its own difficulties. But given an AFNI src directory, and assuming you have installed packages according to afni/src/other_builds/OS_notes.macos_11_ARM.txt, it might be enough to run:

cd afni/src
cp Makefile.macos_11_ARM_clang Makefile
make itall

and then sync the results to your abin. Is that something that you might consider?
