Please do as Satish previously suggested
~/petsc/lib/petsc/bin/win32fe/win32fe cl --use clang --verbose sizeof.c
Also do
clang sizeof.c
and send the output of both. Where sizeof.c is
#include <stdio.h>
int main(int argc,char **args)
{
printf("%d\n",(int)sizeof(int));
return 0;
}
I may have typos in my sample code so please fix those.
