SPEC: How to specify package ARCH for REQUIRES?

[Christian Rohrmeier SCHERING DE]

Hallo All,

OS: RHEL 3 AS
Arch: X86_64

The Question in Brief:
How do I specify in the REQUIRES section of an RPM SPEC file which
architecture of  a depency is to be installed when there is one package
with two or more different architctures available?

More Detailed Information:
I am trying to make a virtual package that, when installed, brings in a
number of other packages. The packages are requirements for some other
software: Oracle has specified that the following packages need to be
installed:

make
gcc.x86_64
gcc-c++.x86_64
libstdc++.i386
libstdc++.x86_64
etc.

Notice that the i386 version libstdc++  is to be installed as well as the
x86_64 version!

If I try to specify that in my SPEC file as such:

Requires: make, gcc.x86_64, gcc-c++.x86_64, libstdc++.i386,
libstdc++.x86_64

then, using Yum for example, or APT, or whatever, the package won't install
because there is no such package "libstdc++.i386" for example.

If I set the SPEC as such:

Requires: make, gcc, gcc-c++, libstdc++

Then the package installs just fine, however, only the x86_64 versions of
the dependencies are installed, not the (as Oracle specifically wants) the
i386 version.

Looking at the RPMs themeselves, for example libstdc++:

[root xxx os]# rpm -qp libstdc++-3.2.3-52.i386.rpm
libstdc++-3.2.3-52
[root xxx os]# rpm -qp libstdc++-3.2.3-52.x86_64.rpm
libstdc++-3.2.3-52

There are two packages, one for i386 and one for x86_64. Further
information on the packages:

[root xxx os]# rpm -qpi libstdc++-3.2.3-52.x86_64.rpm

RPM evidently isn't able to destinguish between the two. They are
identical!

Hence: How do I specify in the REQUIRES section of an RPM SPEC file which
achitecture of  a depency is to be installed when there is one package with
two or more different architctures available?

Many thanks,

Christian
