Hi All, Instead of using embedded asm ( __asm), how could I write a arm64.s file and integrate to a command line test project with c files ? #include <stdio.h> extern int myadd(int a, int b); int main(int argc, const char * argv[]) { // insert code here... printf("Hello, World!\n"); int r = myadd( 10 , 4); return 0; } And .s file .global myadd .p2align 2 .type myadd,%function myadd: // Function "myadd" entry point. .fnstart add r0, r0, r1 // Function arguments are in R0 and R1. Add together // and put the result in R0. bx lr // Return by branching to the address in the link // register. .fnend Error -- /Users/prokashsinha/Arm/ArmAndC/asmfunction.s:9:1: error: unknown directive .type myadd,%function ^ /Users/prokashsinha/Arm/ArmAndC/asmfunction.s:12:1: error: unknown directive .fnstart ^ /Users/prokashsinha/Arm/ArmAndC/asmfunction.s:13:5: error: invalid operand for instruction add r0, r0, r1 ^ /Users/prokashsinha/Arm/ArmAndC/asmfunction.s:15:1: error: unrecognized instruction mnemonic, did you mean: b, bcax, bl, br, sb, tbx? bx lr ^ /Users/prokashsinha/Arm/ArmAndC/asmfunction.s:17:1: error: unknown directive .fnend ^

Folks I'm trying to handle a linking problem coming out of linking a command line app to a c++ based library. But if I defined those methods inline with the class definition, no problem is there ...

Folks, I've a bare bone XPC Service, built with Xcode 12.x. I can get it work under Xcode interactive debugger. But from command line I get the Illegal instruction. A similar project with XPC client don't see the problem. Any help ? Eventually it would be part of launchctl based daemon TIA -P

On 11.3 and 11.4 I see some of the log entries are missing when using os_log(Default, "...."); Wondering if there is a configuration param I should use. Also does it matter, if I have my own serial and concurrent queues ( 'm not worried about the sequence of the print, just that will it print into log , so some form of $ low collect I can use) Thanks, Prokash
