It seems that binaries on the DTK are built for arm64e architecture, as you can see :
However, when I try to build binaries for arm64e it doesn't seem to work. Take this sample program:
Compiling it for either arm64 or arm64e works fine, but I can only run the arm64 version:
I don't know why the arm64e version is killed, I couldn't find anything suspicious in the logs.
Apple's docs don't seem to mention any differences between arm64 and arm64e, but since they build things for arm64e I assume that is what we should do too?
Code Block zsh % lipo -info /bin/ls Architectures in the fat file: /bin/ls are: x86_64 arm64e
However, when I try to build binaries for arm64e it doesn't seem to work. Take this sample program:
Code Block C #include <stdio.h> int main() { printf("Hello ARM\n"); return 0; }
Compiling it for either arm64 or arm64e works fine, but I can only run the arm64 version:
Code Block % clang -arch arm64 main.c && ./a.out Hello ARM % clang -arch arm64e main.c && ./a.out zsh: killed ./a.out
I don't know why the arm64e version is killed, I couldn't find anything suspicious in the logs.
