I'm trying to compile a program called PEAR and it seems there is something wrong at this step.
I have Xcode installed.

I am trying to use MacBook Air 2022 compile a package. However, when I compiled the Makeile, the error of Undefined symbols for architecture arm64 responsed. I looked for many resolutions but all unhelpful.
The Makefile as follow:
CC = gcc-12 -Os -fopenmp
CFLAGS = -L/usr/local/sac/lib -lsac -lsacio -lm
BIN = ../bin
FDTCC: FDTCC.o sacio.o
${CC} -o ${BIN}/$# $^ ${CFLAGS}
clean:
rm -f \*.o
the whole error as follow:
gcc-12 -Os -fopenmp -o ../bin/FDTCC FDTCC.o sacio.o -L/usr/local/sac/lib -lsac -lsacio -lm

Could anyone tell me how to slove this error, thanks.
I'am trying to compile jab code (cf. https://jabcode.org/create) on my MacBook with M1 ARM. I do succeed with the first step of compiling jabcode with the given Makefile:

ld: symbol(s) not found for architecture arm64

make: \*\*\* \[bin/jabcodeWriter\] Error 1
I already tried to add -lstdc++ to CFLAGS in all Makefiles, as suggested here, which generates warnings of "'linker' input unused" for jabcode and does not resolve the problems when trying to compile jacbodeReader of jabcodeWriter.
Also I tried to compile as x86_64, following this question, by adding -arch x86_64 to CFLAGS in each Makefile. The error remained as above Undefined symbols for architecture x86_64 and
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Sorry if the answer is obvious, I'm no expert in C/C++ and Makefiles and could not find any solution here.
I've checked the sources on github and I've checked the flags that you pass to g++ and the answer is quite simple.
You are linking against a static tiff library that wasn't build for your architecture. Look at the folder to which you point with the -L flag.
The author states that he tested it on his ubuntu machine so presumably it is build for the amd64 architecture.
To solve this you need to get the dependencies that you link (tiff is one of them) for your machine and link against it. On MacOS that is usually done using the homebrew package manager.
I tried to assemble a Hello World but ld is throwing me a couple of errors.
Hello World:

nasm & ld:
nasm -f elf64 main.asm
ld main.o -o main
ld gives me these errors:

Undefined symbols for architecture unknown:

I tried using nasm with macho64
nasm -f macho64 main.asm
and got the following errors from ld:
ld: warning: alignment (1) of atom '_start' is too small and may result in unaligned pointers

Thanks in advance
So I'm trying to assemble this piece of 16bit assembly code on my Mac (Monterey):
global _main
section .text
_main:
mov ah, 0x0e
mov al, '!'
int 0x10
mov ah, 0x4c
int 0x21
I am using the NASM assembler, and have so far managed to get it assembled into a .com file using the following command:
nasm testing.asm -o test.com -f bin
However when trying to link this into an executable using LD with the following command:
ld -e _main -static -o test test.com -arch x86_64
it comes up with the error:
standing-x86_64 but attempting to link with file built for
unknown-unsupported file format ( 0xB4 0x0E 0xB0 0x21 0xCD 0x10 0xB7

architecture x86_64: "_main", referenced from:
-u command line option ld: symbol(s) not found for architecture x86_64 ```
Does anyone know how to fix this?
I have problem with compilation .asm file on macOS can somebody help me?
Here is my repository:
https://github.com/ondrej-111/Asm.git
I tried to compile it with this commands:
nasm -f elf -d macho64 asm_io.asm
nasm -f elf prvy.asm
gcc -c driver.c
gcc -o prvy driver.o prvy.o asm_io.o
but I always get the same error:
ld: warning: ld: warning: ignoring file asm_io.o, file was built for

I searched some similar issues but any one helped me to fix it.( I tried this - How can I run this assembly code on OS X?)
