Hi, can you point me to the definition that the ARM v7 processor with a floating-point unit should use "armv7hl" instead of "armv7l". Thank you.

I'm afraid that this is a case of "defined by implementation", and I can't find a quote from any specification document. It seems simply to be the case that armv7hl package repositories exist (eg. Fedora).
What I find at best is some mentions of them, in RPM source code. https://github.com/rpm-software-management/rpm/blob/master/rpmrc.in
If RPM architecture naming is not very well specified, maybe it's not the best leg for VST to stand on?
@x42, perhaps you know more on this?
I too have wondered where to find the canonical reference of "RPM Terminology" that the VST3 spec mentions.
@x42, perhaps you know more on this?
Not really, I have only got armv7hl RPM packages. I was not aware that any RPM provided armv7l
packages, until now.
"armv7hl" is the most widespread ad-hoc architecture used for .rpm [1], the only "armv7l" RPMs were made by openSuSE and are discontinued since 8 years [2]. What's worse is that Fedora recently changed to use armhfp
[3].

I'm beginning to think that as well. Perhaps https://steinbergmedia.github.io/vst3_doc/vstinterfaces/vst3loc.html#linuxformat
should make it explicit. Remove the "based on the RPM Terminology", and suggest uname -m
instead.

[2] https://lists.opensuse.org/opensuse-arm/2012-05/msg00037.html established armv7hl
and mentions that there's no standard

OK, thanks both for your comments. We will change the documentation to use "uname -m" and make a hint about an implementation in module_linux.cpp.
Hi, the
VST 3 Locations / Format
documentation indicates the following as Linux is concerned.MyPlugin.vst3/Contents/XXXX-linux => with XXXX the architecture name (based on the RPM Terminology + "-linux"),
I am told that this specification is in disagreement with the practice currently found in some hosts and plugins, including the hosting code provided by Steinberg.
This is the current state of things:
armv7hl
uname
of this processor, as used by most code out there, indicatesarmv7l
If the specification is to be believed, I should use
armv7hl
, but my users report this as non-working. (eg. Reaper host for Raspberry Pi computer)If the plugin author should use
uname -m
as naming convention as opposed to RPM, it will be great to make this clear in the document.notify @x42, author of VST3 support in the Ardour DAW
