I have a MacBook Pro with Core 2 Duo processors (64bit). I
originally
had a straight install of Fedora 8 on it, which worked
fine. My first
mistake was trying to upgrade to Fedora 9. It had problems
upgrading
basic packages. Then I tried a clean install of Fedora 9
(backup /
format / install). I had better luck getting a functional
system, but
now I've run into another roadblock....

I use my laptop as a development platform in a network with
a mix of
i386 and x86_64 linux boxes. On the current project I'm
working on, we
develop for the "lowest common denominator",
which is i386. Other
projects we compile to x86_64 so I need to be able to do
both relatively
transparently. The libraries for the current project are on
our network
fileserver and are i386. With fedora 8 this was no problem
whatsoever -
I just use the "-m32" switch when compiling on my
machine and everything
worked. With Fedora 9 the first hint of disaster was an
error message

"/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h:
No such file or
directory"

Okay, so for whatever reason, the i386 compatibility
libraries /
includes / whatever weren't installed. I go to install
them and guess
what, there is no such animal in any of the fedora 9
repositories. Doing
a little more research, I find that the
"gnu/stubs" files are in
glibc-headers. Fedora 9 uses version 2.8.3 for x86_64. I
find the
glibc-headers-2.8.3.i386.rpm file on RPMFIND. When I try to
install it,
many of the files conflict with ones from
glibc-headers-2.8.3.x86_64.rpm.

I had an experience like this
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory

But Ralf gave me direction and helped me here.

# rpm -qf /usr/include/gnu/stubs-32.h
glibc-devel-2.8-3.i386

The solution was to install the .i386 packages for what you need. I just did a yum list nameofpackage* and I have x86_64 bit machine as well, I got the i386 packages and was good to go. You may need to do the same.

As for the names of the packages, I do not know which ones specifically you need.

How can I compile and link C, C++, and FORTRAN code for the
i386
architecture on my x86_64 machine.

Install the i386 devel packages and this should work:).

Regards,

Antonio
