This seems to be a problem with you compiler installation. What is the output of c++ -Wl,--version?

kamulchik commented 2 months ago

I am so sorry. Yes, it is compiler depends problem. Resolved.

SpotlightKid commented 2 months ago

No problem. Glad you could get it working.

kamulchik commented 2 months ago

No problem. Glad you could get it working.

Not yet. I resolve a problem compiler installation. But can't install python-rtmidi. I have opkg packet manager, and i not have a package libasound2-dev or jack. But i have libasound.so.2. And i have a alsactl. Path: find / -name "libasound*" /storage/.opt/lib/libasound.so.2.0.0 /storage/.opt/lib/libasound.so.2 /usr/lib/libasound.so /usr/lib/libasound.so.2 /usr/lib/libasound.so.2.0.0

find / -name "alsactl" /storage/.opt/sbin/alsactl /usr/sbin/alsactl

Any workaround for install python-rtmidi. Current ERROR:

SpotlightKid commented 2 months ago

You need not only the ALSA libraries, but also the header files, which are usually installed in /usr/include/alsa adn included via /usr/include/asoundlib.h.

In don't know which package on your distro (openwrt?) provides these files. Maybe alsa-lib?

Distro: CoreElec. find / -name "asound*" /proc/asound /storage/.opt/include/sound/asound.h /storage/.opt/include/sound/asound_fm.h /storage/.opt/var/lock/asound.state.lock /storage/.opt/var/lib/alsa/asound.state

opkg install alsa-lib Package alsa-lib (1.2.9-1) installed in root is up to date.

SpotlightKid commented 2 months ago

Nope, these are not the droids...err...headers we're looking for.

SpotlightKid commented 2 months ago

It seems the header files are not included in the alsa-lib package:

https://github.com/openwrt/packages/blob/openwrt-22.03/libs/alsa-lib/Makefile#L71

So, if you want to compile python-rtmidi on this system, you need to find way to provide these headers and an alsa.pc pkgconfig file in a location where pkgconfig can find it, which returns the correct cflags and ldflags for the alsa lib.

kamulchik commented 2 months ago

@SpotlightKid i built alsa libs from sources and copy to directory files to "include" dir such as asoundlib.h, asoundef.h etc... I got a new error. Please, tell me what i can investigation for this error:

P.s. i now, that this hardest method for install rtmidi, but i don't know other...

You also need the Python header files, so Python.h etc. in the directory returned by pkgconfig --cflags python3.

I thought that meson would detect this when checking for Python's presence, but obviously it doesn't and I should have included a more thorough check that the Python headers are present. I will add this in future python-rtmidi versions.

I think your distro is not really meant for building software directly on the device. In the long run, you're probably better off setting up a cross-compilation build environment on your PC.

How i can check it? Because directory have a Python header files:

Sorry, my assessment was a bit hasty. It seems that your system has the Python headers installed after all.

So it is probably a problem with the C++ code generated by Cython.

I'm not sure if it is using the generated C++ code from the source distribution or if it is generating it on your system.

Are you compiling from the source distribution (e.g. by using pip install) or from the git repo?

From PyPi, like a manual. https://spotlightkid.github.io/python-rtmidi/installation.html Section "From PyPI"

SpotlightKid commented 2 months ago

Can you try installing from the git repo as described here?

git clone --recursive https://github.com/SpotlightKid/python-rtmidi.git
cd python-rtmidi
[sudo] python -m pip install build installer
python -m build --wheel
[sudo] python -m installer dist/*.whl

@kamulchik Any luck compiling python-rtmidi on CoreElec yet?

You are right. So I lost a lot of time for tries. At now, i have beautiful error: module 'venv' has no attribute 'EnvBuilder'. When envvuilder installed : ^) I need more time....
