Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] Daisy build info

yes, the binary should work regardless of the host. You'll need to place it and the headers where your crosscompiler can find it.

Looking forward to seeing your projects.

I guess I can hopefully just use the arm-cortex-m7 build in the beta release. I still have to work out how I'm going to work with Daisy. I have three Noise Engineering Eurorack modules that are based on Daisy Seed, so I should try working with one of those first (probably Alia). I plan to start by adapting the Risset Harmonic Oscillator and the Binaural Reanimator designs that I made for the Qu-Bit Nebulae. It will probably be a while until I have anything to show/share....

Looking at crtosscompile.cmake, I see

SET(CMAKE_FIND_ROOT_PATH  /usr/arm-none-eabi /usr/lib/arm-none-eabi)

which suggests that maybe this has never been used on Windows.

The toolchain does seem to be in the path, since I can execute "arm-none-eabi-gcc.exe -v" without errors.

OK, I now have the Daisy toolchain installed, and the latest Csound develop. Following the instruction, I navigate to the build dir and execute

cmake .. -DCMAKE_INSTALL_PREFIX=../Daisy -DCUSTOM_CMAKE=../Daisy/Custom.cmake -DCMAKE_TOOLCHAIN_FILE=../Daisy/crosscompile.cmake

this produces an error:

  It fails with the following output:

So apparently it is passing gcc options to the MSVC compiler. What do I need to do to get it to use the Daisy toolchain instead?

Indeed, it was committed. It's in a PR now
https://github.com/csound/csound/pull/2267

But you don't need to build it yourself, just download the package from the latest release.
