Max gen~ build fails

Hi ,

I just tried to compile a fairly simple GEN patch (just a very long stereo-delay), following the WIKI pages, and got the following errors:

Omni@OmnisM1 max-gen-deploy % ./
Please type your plugin name, then press enter to confirm

Error: Process 61379dad96c4f7c7718404d5 failed, contact MOD Team for more details

Here is the patch and the inside of the gen object:


Hi @Omnichordman . Thanks for your report.

This is a different issue. Let us investigate and we’ll get back to you.


Can you try renaming the exported files as gen_exported.cpp and gen_exported.h and running the script again?

Hi falk,

I did that.

…and? same result?

It did not even start to compile with other names.
Funny thing is, I just found a delcore1 in the plugin list, which is my name for the gen object, before renaming.

Does not work though…

Yeah I found out why now.
One step of the cloud builder is not being run, which renames the includes in order to build.

This is made for GNU sed, so not sure if it runs on macOS as-is. But you can try:

sed -r 's/(namespace )(.*)\{/\1gen_exported \{/g' -i gen_exported.*
sed -r 's/(#include )(.*)/\1"gen_exported.h"/g' -i gen_exported.*

(which are the steps the cloud should be running but is not)

we basically want to edit the files to convert custom names to well-known name for compilation, that name being gen_exported.
after modifying the files you should be able to get this to work.

we will fix the MOD cloud side too, but that can take a bit.

Thanks Falk,
I will try that later. Can I use a terminal program for that?

I am not a coder, just Max/MSP experienced, tapping into GEN now…

You have to use the terminal :wink:

But okay, understable if you dont want to try, since I dont even know if it will work as-is.

I just pushed the fix to our cloud code, will need to rebuild the images and redeploy.
Now passing the ball to @acunha again :sweat_smile:

You bet I will try…. :wink:

Cloud pipeline has been fixed (or at least applied the tentative fix from falk :stuck_out_tongue: ).
@Omnichordman please try again.

It worked, I got a LoongDelay.lv2-duo.tar.gz file back. I had to rename the files to gen_exported though, before it worked. Now I am stuck somewhere else, see here:

Excuse my ignorance, it´s day three in lv2/Dwarf land…

I am a step futther now I guess, after reading your post here:

I got a loongdelay.lv2-dwarf.tar.gz file back without errors. I will explore how to get it a skin.

If you get into issues not being able to run mod-sdk (which to be honest needs some maintenance work on our side) we have been internally using a special build which provides a few extra developer tools. Basically v1.10 + carla + mod-sdk + valgrind.
Will post a build here once it is finished.

ok went a step ahead and added a little bit of documentation as well.
See Developer Images - MOD Wiki


@falkTX thanks for the headstart! I will look into it asap. Does it make sense to work from a Linux Ubuntu enviroment, insted of Mac OS? Seems like all the tools are ready and availiable there.
I could use my Raspi 3 for that.

for development, yes for sure.
while you can setup things while in macOS, there are always extra steps. but I cant recommend using as rasp-pi for development…

hi guys, just begining to start a patch up in max but don’t want to do much if the process for getting it onto dwarf is not stable. any thoughts on current state of max patch to running on the pedal. thanks

The Max-gen stuff works fine as far as we know.
But worth noting again that the whole thing refers to Max gen~ objects only, not to full Max projects.


You won’t be able to run max/msp on linux though (I mean I got it mostly to work in wine on amd64, except for the package manager and the MOD plugin), definitely not on a pi.

I’d recommend using pure data, together with hvcc, that will run on your pi for sure. The only downside is you need a bit more command-line skills to get a plugin built. There is no web-service taking care of the build for you like with the MOD plugin for Max/MSP.
