"Illegal instruction: 4" on Mid-2010 Mac Mini, MacOS 10.13.6

[hbent]

dmidecode compiled with -O0 -g3 on a Mid-2010 Mac Mini, MacOS 10.13.6. I am not really a Mac person and I'm at a loss as to how to proceed:

bash-3.2# gmake dmidecode
gcc -W -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wmissing-prototypes -Winline -Wundef -D_FILE_OFFSET_BITS=64 -O0 -g3 -Wno-constant-logical-operand -c dmidecode.c -o dmidecode.o
gcc -W -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wmissing-prototypes -Winline -Wundef -D_FILE_OFFSET_BITS=64 -O0 -g3 -Wno-constant-logical-operand -c dmiopt.c -o dmiopt.o
gcc -W -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wmissing-prototypes -Winline -Wundef -D_FILE_OFFSET_BITS=64 -O0 -g3 -Wno-constant-logical-operand -c dmioem.c -o dmioem.o
gcc -W -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wmissing-prototypes -Winline -Wundef -D_FILE_OFFSET_BITS=64 -O0 -g3 -Wno-constant-logical-operand -c util.c -o util.o
gcc -framework CoreServices -framework IOKit dmidecode.o dmiopt.o dmioem.o util.o -o dmidecode
bash-3.2# ./dmidecode

@hbent
Follow your instructions, Why does it still prompt "illegal instruction: 4".
My computer's operating system is MacOS Catalina v10.15.I hope you can answer my question,thank you.

For some reason, latest code is older than 3.1 relese.

if (NULL != properties)
     CFRelease(properties);

must be commented out.
