Greetings, and please excuse the delay in this reply.
I thought this was fixed in the following snippet of 2.6.8pre:
AC_MSG_CHECKING([for ADDR_NO_RANDOMIZE constant])
AC_TRY_RUN([#include <sys/personality.h>
#include <stdio.h>
int main(int argc,char *argv[],char *envp[]) {
FILE *f;
if (!(f=fopen("conftest1","w"))) return -1;
fprintf(f,"%x",ADDR_NO_RANDOMIZE);
return 0;
}],
ADDR_NO_RANDOMIZE=`cat
conftest1`,ADDR_NO_RANDOMIZE=0,ADDR_NO_RANDOMIZE=0)
if test "$ADDR_NO_RANDOMIZE" = "0" ; then
AC_MSG_RESULT([no, assuming 0x40000])
AC_DEFINE_UNQUOTED(ADDR_NO_RANDOMIZE,0x40000)
else
AC_MSG_RESULT([yes, $ADDR_NO_RANDOMIZE])
fi
Is it possible this code is not what you are testing? If it is, could
you please send your configure output?
Take care,
