Operating Systems Linux SuSE 64 bit Porting Problem !!! Post 302275047 by skaushal.schip on Friday 9th of January 2009 04:21:55 AM

Hi Otheus,

You are right on the point that I want to know the architecture of the CPU. Doing "isainfo" on Solaris gives the CPU architecture but the command is not working on Linux. I also did "cat /proc/cpuinfo" but its not providing the architecture type which I could use in -march switch. Even in gcc manual i could not find the appropriate value.
To check the appropriate flags to get desired warnings I wrote a sample code which is as follows:

#include <iostream>

using namespace std;

int main()
{
unsigned long ul = ~1UL;
int i = 20,j;
int *ip = &i;
i = ul;
j = (int) ip;
return 1;
}

If I build the code on 64 bit machine I should get warnings for the following two lines:
i = ul;
j = (int) ip;
But when i copiled it with "gcc -c -m64 -Wall -Wmissing-prototypes" I am getting only one warning i.e. "warnings.cpp:11: warning: cast from pointer to integer of different size". I am not getting warning for long to int assignement for the line "i = ul;".
Could you suggest me something on this.

Regards,
Saurabh
