Please provide instructions for building on aarch64 on Linux #324

Please provide instructions for building on aarch64 on Linux. Using

git clone https://github.com/asb2m10/dexed.git
cd dexed
git submodule update --init --recursive
./scripts/get-juce.sh
./scripts/projuce-lin.sh
./scripts/build-lin.sh

does NOT work as the processor architecture seems to be hardcoded at least in projuce-lin.sh.

probonopd commented 2 years ago

It must be possible somehow because https://kx.studio is offering working builds.

JUCE provides/requires use of an x86-64 binary.

Thanks @jbates-duality however I want to build for ARM 64-bit, not Intel/AMD 64-bit.

Since https://kx.studio/ is offering working builds, it must be possible to build Dexed for that architecture somehow.

Please use CMake to build Dexed, it should now work out of the box: https://github.com/asb2m10/dexed/blob/master/README_cmake.md

Thank you very much @asb2m10.

(Semi unrelated side note: Have you seen MiniDexed, the "embedded" version of Dexed running on bare metal Raspberry Pi without a Linux kernel?)

Hi there. Thanks for getting back to us. It is appreciated.

I've pulled and followed the cmake instructions. I think that a compiler flag needs to be added, at least for the default compiler on a fresh raspbian install. When I have some time tonight, I might dig into this a bit. Here's the diagnostic:

Hi,

Don't hesitate to provide pull-request with the missing compiler flag. I'm on gcc 11.2.0 (arch linux), the CMake built was originally made on debian, I'm surprised it doesn't work on your side.
