How to identity processor architecture
Hi Dear,
I just wanna to know my processor architecture(32bit or 64 bit) through c programming.
According to me the sizeof of pointer will give the result. Like below coding.
int main()
{
int *ptr;
printf("%d",sizeof(ptr));
}Please correct me if i am wrong...
Any suggestion or help would be appreciated.
Thanks,
Prabhu
What if one is compiling 32bit code on a 64bit processor? Would 4 be an acceptable result to you in that case?

the size of the integer variable will be equal to your processor architecture(32bit or 64 bit).

Hi Enrico,
I am not sure.
No, because 32bit code will tell the datatype size and i think pointer variable depends on architecture.
So 64 bit processor needs 64 address line to point the data location. So pointer variable needs to be 8 byte.
please correct me if i am worng.

Please don't top post and please use the new list address, ok? :)
IMO, I second your opinion. And as addition, I think it's worth to check /proc/cpuinfo too in "address sizes" field
NB: I was thinking, if in x64, it is operating in full 32 bit mode (not hybrid one), it is supposed to yield 32 bit address too, right?

I guess a 64bit processor does need 64bit addresses to reference memory. But at the same time, if 32 bit programs are to run unmodified on 64 bit architectures there needs to be ways in which 32bit pointers can still work. So, I am almost 100% sure that compiling 32bit code, even on a 64bit processor, should yield 4 for sizeof(void*)

You are 100% right. Tried this on 2 laptops:
printf("Is this a %s-bit machine?\n", ((sizeof(void*) == 4) ? "32" : "64"));
32-Bit ubuntu (10.10) on 64-bit proc:

Hi Mandeep,
Thanks a lot.
So is there any other way available to identify the processor architecture using c code?? . The program needs to return correct processor architecture(32bit or 64bit) irrespective to the OS architecture.

Thanks a lot folks.
Adding more detail on this.
Below detail helps to understand CPU architecture. _*
*__*Finding CPU Arch*_
$ grep flags /proc/cpuinfo | uniq | egrep -o -w "rm|tm|lm"
Under "Flags" section in /proc/cpuinfo, you will find any of the
flags "tm" or
"rm" or "lm"
* rm (Real Mode) means it is a 16 bit processor
* tm (Transparent Mode) means it is a 32 bit processor
* lm (Long Mode) means it is a 64 bit processor
Is this only way to find the processor architecture ????
Any C programming technique apart from using this /proc/cpuinfo detail?
Thanks,
Prabhu

What about using the machine field of uname(2):
$ man 2 uname
Quoting from that man page:
[...] the operating system presumably knows its name, release
and version. It also knows what hardware it runs on.
Perhaps a downside, it returns the machine type as a string. Does that do what you want?
I also find "man linux32" rather interesting:
setarch - change reported architecture in new program environment and set personality flags
Might be useful for testing.

Also , the below one could help.

Both Ideas give the Kernel architecture not cpu architecture.
You can get exact cpu architecture through lshw command.

Wrong mailing list, you should ask such question on busybox mailing list,
besides this is a kernel related mailing list or gcc-powerpc mailing list.

Busybox for powerpc doesnt compile
In reply to yy HongHi,
?Thanks for the details. Glibc configures, makes, and installs fine:
../glibc-2.9/configure
--host=powerpc-linux --target=powerpc-linux- --prefix=/opt/mpc8250/tools/glibc2.9 --build=i686-pc-linux-gnu --with-headers=/opt/mpc8250/tools/ppc_6xx/usr/include/ --cache-file=config.cache
Now, I try to compile busybox.1.17.1 as :
?make ARCH=powerpc CROSS_COMPILE=powerpc-linux-
At the very end, errors as :
Trying libraries: crypt m
?Library crypt is not needed, excluding it ?Library m is not needed, excluding it
Final link with: <none>
powerpc-linux-strip: there are no sections to be copied!
make: *** [busybox] Error 1
.config:CONFIG_EXTRA_CFLAGS="-I/opt/mpc8250/tools/ppc_6xx/usr/include/ -L/opt/mpc8250/tools/ppc_6xx/usr/lib/ -L/opt/mpc8250/tools/glibc2.9/opt/mpc8250/tools/glibc2.9/lib -nostdlib"
Can any please suggest why?

It seems you toolchian dosen't contain libcrypt.you can compile it into your toolchain and try again.
Also tried:

Any clues as to why this happens?

No, because 32bit code will tell the datatype size and i think pointer variable depends on architecture.
So 64 bit processor needs 64 address line to point the data location. So pointer variable needs to be 8 byte.Please don't top post and please use the new list address, ok? :)
Sure, Thanks for your reply.

IMO, I second your opinion. And as addition, I think it's worth to check
/proc/cpuinfotoo in "address sizes" field
I am getting below output for /proc/cpuinfo . I hope *cpu family : 6 *means x86 family(32 bit processor). What if its 64 bit processor. ( I dont have system to check this.)

NB: I was thinking, if in x64, it is operating in full 32 bit mode (not hybrid one), it is supposed to yield 32 bit address too, right?
I'm sorry . I have no idea about this.
Thanks,

according to http://en.wikipedia.org/wiki/Pentium_Dual-Core, yours falls into Allendale core category, which is already using Intel 64 technology. So, unless I am mistaken somewhere, yours is x64. The problem is, is it working in hybrid 64/32 bit or in full 32 bit ....?

Why not simply use CPUID ?

In this case solution is not portable and uses arch specific methods. I think most 64-bit systems today use LP64 data model.
