Compilation instructions & requirements?

[opjose]

Are there instructions for compiling from source and the requirements for this?

Also has anyone tried cross compiling on a Linux X64 install?

Thanks!

Here is the way I was able to get a successful compile right out of the source code:
At high level:
1-Download (from here) and extract (preferably in the home directly) the arm compiler (make sure it is the bare metal and aarch64-none-elf).
2-Add the pathway to the bin folder of the arm complier (the folder you just downloaded and placed in your home directory) to the rest of your PATH by adding this extra line (export PATH=":$PATH") in your .bashrc
3-git clone --recursive https://github.com/dwhinham/mt32-pi.git. (recursive will assure you are downloading all the necessary dependancies).
4- [optional, if you want the latest version]: Download the latest source code from (https://github.com/dwhinham/mt32-pi/releases) and overwrite it on the mt32-pi folder that you just cloned. The source code alone does not include the dependancies. Therefore, it is necessary to have step 3 done first and place the latest source code on it.
5- make veryclean
6- For Raspberry Pi 3 or Zero 2 used "make BOARD=pi3-64" and for Raspberry Pi 4 use make BOARD=pi4-64
7- Copy kernel8.bin to your SD card (walla!)

This almost works for me, but something is broken. Maybe something in a recent update?

`make[3]: Leaving directory '/home/user/mt32-pi/external/circle-stdlib/build/circle-newlib'
make[2]: Leaving directory '/home/user/mt32-pi/external/circle-stdlib/build/circle-newlib'

When I correct the path in Config.mk for the ../cmake/aarch64-none-elf.cmake it just brakes even more by giving a successful compile of munt, but the pathing and source Makefile stays static with building munt.

I was able to compile this correctly using ubuntu 22.04 instead of 18.04.

Maybe someone can setup a docker container so people can quickly setup something.

Hello,
I'm trying to compile (updating to last release v 0.13.0 ) with Ubuntu 22.04 (WSL) with the suggested compiler arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-elf, using different installation of cmake (3.26 , 3.22. etc..)
I'm always have this error:

patching file src/utils/fluidsynth_priv.h
CMake Error at /usr/local/share/cmake-3.20/Modules/FindPkgConfig.cmake:556 (message):
A required package was not found
Call Stack (most recent call first):
/usr/local/share/cmake-3.20/Modules/FindPkgConfig.cmake:778 (_pkg_check_modules_internal)
CMakeLists.txt:483 (pkg_check_modules)

Any suggestions?

Help me please,

Regards
