Trying to compile Ulab for RP2 using a MBP M1

[alport]

Describe the bug A clear and concise description of what the bug is. Give the ulab version

When I execute the supplied script: RP2.sh, I get the following error: [ -d build-PICO ] || cmake -S . -B build-PICO -DPICO_BUILD_DOCS=0 -DMICROPY_BOARD=PICO -DUSER_C_MODULES=/Users/mike/ulab/code/micropython.cmake /bin/sh: cmake: command not found make: *** [all] Error 127

Any ideas? Alternately, it would really help if someone could supply the final binary which I could upload directly to the RP2 using Thonny.

To Reproduce ./RP2.sh

Expected behavior Should compile the RP2 firmware to the micropython/ports/rp2/build directory.

Context I get the following when I execute the supplied script.

@alport As far as I understand, this issue has nothing to do with ulab: it seems to me that you don't have cmake on your system. You can find some pointers here: https://cmake.org/install/

[alport]

Thanks, but need some more help:

I installed Cmake for the "Mac 10.13 or later". It seems like I had then to configure it for a Command Line Use, by executing the Cmake app, and following the instructions:

After copying CMake.app into /Applications (or a custom location), run it and follow the “How to Install For Command Line Use” menu item for instructions to make the command-line tools (e.g. cmake) available in the PATH.

One may add CMake to the PATH:

 PATH="/Applications/CMake.app/Contents/bin":"$PATH"

which is what I did - and then repeated the ./RP2.sh, which gave me the following error log:

[ -d build-PICO ] || cmake -S . -B build-PICO -DPICO_BUILD_DOCS=0 -DMICROPY_BOARD=PICO -DUSER_C_MODULES=/Users/mike/ulab/code/micropython.cmake PICO_SDK_PATH is /Users/mike/micropython/lib/pico-sdk Defaulting PICO_PLATFORM to rp2040 since not specified.

CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage -- Configuring incomplete, errors occurred! make: *** [all] Error 1

I am also trying a parallel install on another Intel based MBP - but get the same error.

Again, your help would be appreciated...! Thanks,

[alport]

If my problem seems too difficult/involved to figure, an alternative would be if you could provide the actual binary that I could upload to the RP2 using Thonny - would that be possible?

[v923z]

@alport Would https://github.com/pimoroni/pimoroni-pico/releases/download/v0.1.0/pimoroni-pico-micropython.uf2 work for you? I don't know, whether later versions of the firmware include ulab. Based on https://github.com/pimoroni/pimoroni-pico/blob/main/micropython/modules/micropython.cmake, I would assume that ulab is included in all versions after 0.1: https://github.com/pimoroni/pimoroni-pico/releases But, on the other hand, you can simply try it out, and if you can't import it, then it is not there. Have you seen https://github.com/pimoroni/pimoroni-pico/blob/main/setting-up-the-pico-sdk.md?

@Gadgetoid Philip, is this something that should be fixed here in the long run? It seems to me that the compiler is not set properly in the cmake file, but I can't really comment on the issue.

I don't think so. It just looks like gcc-arm-none-eabi isn't installed or available in PATH.

The crux of the error is:

CMake Error at /Users/mike/micropython/lib/pico-sdk/cmake/preload/toolchains/find_compiler.cmake:28 (message):
Compiler 'arm-none-eabi-gcc' not found, you can specify search path with
"PICO_TOOLCHAIN_PATH".

@alport I don't have any experience building from macOS, but I'd recommend getting the basic Pico Examples building against the SDK first before upping the ante to MicroPython + Modules. There's a guide here, but I can't vouch for its accuracy: https://blog.smittytone.net/2021/02/02/program-raspberry-pi-pico-c-mac/

Other than that, I think you're on the right track.

[alport]

Thanks again for the reply. Yes, I has previously seen the Pimoroni Github site, but discounted it since it seemed to be a compile for the PicoSystem - a handheld gaming screen. But I am willing to try your .uf2 link and will report back.

[Gadgetoid]

seemed to be a compile for the PicoSystem

Not at all- it's a build with MicroPython bindings for all of our RP2040 C product libraries. Intended for the original "Pico" board and variants thereof. (of which I suppose the PicoSystem is one!)

[alport]

Thanks, your .uf2 link works - now have another toy to play with - ulab!!!

[v923z]

@alport Mike, can we close the issue, or do you still have difficulties with the compilation?
