- Subject: cannot compute sizeof (int), 77 on G5
Hi. Regardless of what cflags I use, making gcc seems to always die
during the configuration of libiberty. I get this error:
checking size of int... configure: error: cannot compute sizeof (int), 77
See `config.log' for more details.
make[1]: *** [configure-target-libiberty] Error 1
There doesn't appear to be anything particularly unusual in config.log:

it should be noted that what I'm attempting to do is build a bunch of
utilities (gcc with fortran in this instance) that will be shared among
all of our powerpc macs. It'll be shared via nfs on the desktops
(mostly G5s and maybe one or two G4s) and rsynced onto the laptops (all
G4s). I'm doing the building on a dual G5 with OSX Tiger and GCC 4.0.0
(that came with the apple's developer tools).
I suspect that this problem has something to do with building for a
powerpc32 on a powerpc64, but alas, I've been tasked with this and would
like to be able to do it if possible.
I've been running configure with these options:
--prefix="/seis/local/macPPC" --host="powerpc-apple-darwin"
--with-mpfr="/seis/local
/macPPC" --with-gmp="/seis/local/macPPC"
CFLAGS that I have used with this configuration in various attempts have
been -O3, -O2, -ftree-vectorize, and -no-cpp-precomp.
Thanks,
Philip
