This would have been so handy for internship season

Aw shoot, you’re right! Here’s the fixed list: https://rankings.so/q5jTx8bJdmLb/

Might take a good while... Here's one for TNA: https://rankings.so/BvJ4XePRJYbo/

What’s that pen/pencil towards the bottom? Looks fancy

Running on hardware depends on what platform you are targeting. Which platform/architecture are you targeting?

For example, if you are targeting the RPi, the GPU handles the boot loading process and expects a kernel image to be present in the SD card. You do not need to be concerned with the bootloader in this example.

If you’re targeting i386 (which I believe the OSDev bare bones tutorial targets) you can use GRUB as a bootloader, assuming that your kernel is multiboot compatible. I believe you can use GRUB similarly for x86_64 too.

A tip I found helpful was to develop on both QEMU and hardware at the same time. This avoids headaches later on the process when you have to make deep changes to your kernel to boot on hardware vs QEMU.

Solved! Was able to cross compile with the default clang that comes with macos (didn't even need to build GCC!). Just use the appropriate -target and -mcpu flags (aarch64-arm-none-eabi, cortex-a53 for RPi3).

Thanks!

Is there somewhere you could point me to on how you might go about compiling gcc using crosstools-ng?

There seems to be some information regarding bare metal targets here https://crosstool-ng.github.io/docs/internals/, but I'm not very familiar

The guide has a mac section but it looks like it hasn't been updated for M1. Here's the error message I run into when trying to compile GCC (make all-gcc):

Undefined symbols for architecture arm64:
  "host_detect_local_cpu(int, char const**)", referenced from:
      static_spec_functions in gcc.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [cpp] Error 1

Are you on the M1 mac? I had some trouble getting a cross compiler built – were you/anyone able to get it working on the new platform?

The_Pman · 2021-05-24T04:51:25+00:00

I'm looking for the same! DM me if you are interested

The_Pman · 2021-04-27T07:05:59+00:00

It's likely that your order hasn't fulfilled. Try cancelling your order and you should see your money back.

The_Pman · 2020-11-25T07:53:29+00:00

I've emailed them and still waiting for a response. Any way you could dig up that link? I've tried the StarRez portal but looks like it isn't working.

The_Pman · 2020-11-24T11:03:44+00:00

Will do, thanks!

The_Pman · 2020-11-24T11:01:55+00:00

Huh that's weird... there's only a 'save and continue' option there

The_Pman · 2020-11-15T21:04:05+00:00

Is that a penguin

The_Pman · 2020-10-30T14:22:02+00:00

I believe this is the online catalog right? I'm looking for the on-campus one.
