[fedora-arm] Cross-compiler settings for rpmbuild

[Shakthi Kannan]

Hi,

The hardware device I use for testing is armv4, while the pre-built
rootfs is armv5. I have a custom toolchain which I would like to use
to build the packages from .src.rpm. How can I achieve that with the
rpmbuild process? I don't have an option of building on the target
hardware.

1. If I would like to cross-compile, what should be the BuildArch?

2. Where can I set the cross-compiler settings, for example:

%__cc            /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-gcc
%__cpp          /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-g++
%__cxx           /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-g++
%__ld             /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-ld
%__nm           /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-nm
%__objcopy   /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-objcopy
%__objdump  /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-objdump
%__ranlib       /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-ranlib
%__strip         /usr/local/arm/3.4.3/bin/arm-none-linux-gnueabi-strip

I see that /usr/lib/rpm has lot of configuration files and settings,
and /usr/lib/rpm/platform is for native builds?

Appreciate any inputs in this regard,

Thanks!

SK
