Makefile works on macos but doesn't on linux

Question

I have a c program with a makefile that works perfectly on macos but when i try yo run it on linux it gives me a bunch of errors

gcc ./libft/libft.a srcs/main.o -o push_swap

collect2: error: ld returned 1 exit status
make: *** [Makefile:23: push_swap] Error 1

I believe the cause is the Makefile because it can't find the function that the makefile is suppose to compile too but im not sure about that. Anyways here is my makefile:

NAME = push_swap
LIBFT_PATH = libft
LIBFT = libft.a

SRC_FILES = main.c 
SRC_DIR = srcs/
SRC = ${addprefix ${SRC_DIR}, ${SRC_FILES}}
OBJ = ${SRC:.c=.o}

CC = gcc
CFLAGS = -Wall -Wextra -Werror -pg -g
AR = ar -rcs

%.o: %.c
    ${CC} -c -Imlx -c $< -o $@

all: ${NAME}

libft:
    @MAKE -sC ${LIBFT_PATH}

${NAME}: libft ${OBJ}
    ${CC} ${LIBFT_PATH}/${LIBFT} ${OBJ} -o ${NAME}

clean:
    rm -f ${OBJ}
    ${MAKE} -C ${LIBFT_PATH} clean

fclean: clean
    rm -f ${NAME}
    ${MAKE} -C ${LIBFT_PATH} fclean

re: fclean all

.PHONY: all clean flcean re
