# I am trying to build amdgpu_top package
$ git clone https://github.com/Umio-Yasuno/amdgpu_top
$ cd amdgpu_top
$ cargo install --locked --path . --no-default-features --features="tui"
$ cargo build --release --target powerpc64le-unknown-linux-gnu # target ppc64le architecture

# got error
#	package amdgpu_top-0:0.2.0-1.powerpc64le is intended for a different architecture
# let's double check the RPM one more time

Unsure if it is the fault of cargo-generate-rpm or rpm itself?

@runlevel5 This is the first time I have heard of the PowerPC 64 LE architecture. I have no PowerPC machine regardless of endian/bits.

cargo-generate-rpm/src/build_target.rs

Line 57 in 52bbfe7

match arch {

It seems to me that we can add a conversion for PowerPC 64 LE to the match expression here. I don't know the proper value, but from your text I'm guessing "powerpc64le" => "ppc64le"?

Yes powerpc64le is ppc64le

PowerPC is used to be more popular in the old days when Apple was producing consumer desktop/laptop. After moving away from PowerPC, the CPU lives on in the enterprise section. Recently IBM and other parties have tried to promote this architecture with the OpenPOWER initiative. The Raptor Computing System Blackbird is probably one of the most affordable OpenPOWER-based workstation since 2019. The price is out of reach for many people but eventually it would get cheaper as more people start embracing it

Thanks for the PR and the detailed explanation of powerpc64le!
