This is a CPUID code.
It successfully compiled on Pelles C.
So I'd like to compile it on MinGW. Since I don't wanna use the AT&T syntax, I change the code a little bitCode://Author - Niloy Mondal //Reference - Intel Instruction Set Reference Volume 2 #include <stdio.h> #include <conio.h> int main() { char *strFeatures[32]={ "FPU - x87 FPU on Chip", "VME - Virtual 8086 Enhancement", "DE - Debugging Extensions", "PSE - Page Size Extensions", "TSC - Time Stamp Counter", "MSR - RDMSR and WRMSR Support", "PAE - Physical Address Extensions", "MCE - Machine Check Exception", "CX8 - CMPXCHG8B instruction", "APIC - Advanced Programmable Interrupt Controller on Chip", " ", //Reserved "SEP - SYSENTER and SYSEXIT", "MTRR - Memory Type Range Register", "PGE - PTE Global Bit", "MCA - Machine Check Architecture", "CMOV - Condtional Move/Compare Instruction", "PAT - Page Attribute Table", "PSE-32 - Page Size Extension", "PSN - Processor Serial Number", "CLFSH - CFLUSH Instruction", " ", //Reserved "DS - Debug Store", "ACPI - Thermal Monitor and Clock Control", "MMX - MMX Technology", "FXSR - FXSAVE/FXRSTOR", "SSE- SSE Extensions", "SSE2 - SSE2 Extensions", "SS - Self Snoop", "HTT - Hyper Threading Tech", "TM - Thermal Monitor", " ", //Reserved "PBE - Pend.

gcc -masm=intel cpuid.c -o cpuid
And these are the error messages :
So how should I use Intel syntax on MinGW ?Code:C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x5c): undefined reference to `VendorID' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x62): undefined reference to `VendorID' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x68): undefined reference to `VendorID' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x6e): undefined reference to `VendorID' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x91): undefined reference to `VersionInfo' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x97): undefined reference to `FeatureInfo' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x9d): undefined reference to `Brand' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x30e): undefined reference to `i' C:/DOCUME~1/ADMINI~1.DIV/LOCALS~1/Temp/cceKbaaa.o:cpuid.c:(.text+0x315): undefined reference to `FeatureInfo' collect2: ld returned 1 exit status
