Problem building #25

Closed Grumpy666 closed 4 years ago

Grumpy666 commented 4 years ago

I'm trying to build the latest version but get the following error:

cc1: error: '-mfloat-abi=hard': selected processor lacks an FPU

I'm using "arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]" under MacOS.

Any hints?

Are you trying to build the master or the raspi2 branch?

Grumpy666 commented 4 years ago

I have tried both. Same result. I also get the error when trying to build the uspi submodule.

chregu82 commented 4 years ago

Raspi2 branch is work in progress. It won't boot. I checked my gcc version, I'm on 7.4.0, which seems to work. You probably need to change some compiler options for newer gcc, but I'm not sure.

Ok, I’ll try to dig up an old version of the tool chain.

Thanks

PiGFX should now be buildable with the latest toolchain.
