[bgl-discuss] configure sizeof fix, perhaps

["Ivan R. Judson" <judson@xxxxxxxxxxx>]

Hi my name is Ivan, and I'm a blue gene hacker [crowd says, "Hi, Ivan"],

I ran into this problem:

checking build system type... powerpc64-unknown-linux-gnu checking host
system type... powerpc64-unknown-linux-gnu checking for int... yes checking
size of int... configure: error: cannot compute sizeof (int), 77

Here's the fix:

1: grab the autoconf macro archive: http://www.gnu.org/software/ac-archive/
2: unpack it and put it someplace useful, say path <p>
3: Edit configure.in and replace:

AC_CHECK_SIZEOF(int)
AC_CHECK_SIZEOF(long)

with:

AC_COMPILE_CHECK_SIZEOF(int)
AC_COMPILE_CHECK_SIZEOF(long)

4: Then run aclocal -I <p>
5: run autoconf
6: run configure again and see if it works.


This recipe has worked for me, now I'm up to being hosed by pthreads. Is
there any special magic there?
