I have used this sample to build a toolchain. However I get 32-bit executables and the '-m64' switch is not recognised. There is obviously a gap in my knowledge which I can't seem to find an answer for on Google. Can I compile a 64-bit executable? If so, how? Thanks for any help.

Sometimes, I expect that when people open pull-requests that they actually test what they submit and I don’t have to do any work. Today I failed at that. Yeay! Arm64/aarch64 is kind of a new thing in crosstool-NG, and isn’t well supported. I took the pull-request for the sample without looking at the specs for the new raspberry pi 3. I had no clue it was 64-bit.

Good to know it's not just me being an idiot! I was hoping to use a toolchain generated with ct-ng to build a 64-bit root file-system using buildroot or just using the toolchain with cross-LFS. I will continue to tinker and at the same time wait to see if there are changes to this sample. It's true that at the moment there are only 32-bit images available. I expect ArchARM to come up with a 64-bit image soon enough though.

Indeed, but someone has to push the edge and give it a go? I need to get myself a PI3. I have to wait till the 15th to order mine, but that doesn’t mean I can’t start getting ct-ng there. I know there are others out there waiting for aarch64 support, so let’s do this. > > Mike Cheers, -Bryan > > > On 03/03/2016 00:28, Stefan Hallas Mulvad wrote: >> Hi Bryan, >> >> I did test this, but at this time there’s (to my knowledge) no os images available which supports 64 bit.

I didn’t realize RPI3 was a 64-bit cpu, and I assumed ct-ng did not have aarch64 support. 0/2… On the plus side, I have something to test: https://github.com/crosstool-ng/crosstool-ng/pull/362 Now, the hard part. You can’t run 64-bit binaries on 32-bit. Also, I’m not sure if you can boot aarch64 from a 32-bit bootloader? So you may have to start with making u-boot? I wish I had an RPI3, so I could help with that, but for now I’ll just have to be patient and wait to hear your progress. If you do make progress, and need help, post a git repo somewhere and I’ll try to help if I can. -Bryan > >> >> >> On 03/03/2016 00:28, Stefan Hallas Mulvad wrote: >>> Hi Bryan, >>> >>> I did test this, but at this time there’s (to my knowledge) no os images available which supports 64 bit.

Incidentally apologies for top-posting but that's another thing with not being able to see...and a bit lazy. But there's plenty of ARM Cortex A53 stuff online so I might be able to just use one of the other configs to hack it.

You’re looking for aarch64, which I’m also looking into - for the minute this works for RPi3 / raspbian.

Indeed, an ARMv8 processor can run both in 32 bits mode or 64 bits mode depending on the use cases. So a single board like the RPi3 can require the use of either an ARM toolchain, or an AArch64 toolchain. So, I think you should stick to configurations for processor cores, not boards. So: arm-cortex-a15 arm-cortex-a7 aarch64-cortex-a53 aarch64-cortex-a72 ... Then, a RPi3 user can chose either an arm-* toolchain or an aarch64-* toolchain depending on what he wants to do.

I can agree with that. I’ll look into renaming the samples soon!
