Error installing libpd via Cocoapods #345

corporate-fun · 2022-03-17T18:55:33Z

I have included libpd in our Podfile like so:

        pod 'libpd-ios', '~> 0.11'

And upon installing I am seeing this error

Installing libpd-ios (0.11.0)

It looks like GitHub is deprecating open git:// links: link 1 and link 2

The fix appears to be to update the submodule links to use https instead. This is done in the latest commit but you will need to change your pod file to take the current git master and not the 0.11 version tag for now, until we release 0.12 soon.

thanks @danomatika. could you tell me what that would look like in the Podfile? I'm having trouble finding what url i should be using. I've tried:

pod 'libpd-ios', :git => 'https://github.com/libpd/pd-for-ios.git'

and

pod 'libpd-ios', :git => 'https://github.com/libpd/libpd.git'

and neither are working:

[!] Unable to find a specification for 'libpd-ios'.

I don’t know. I don’t use CocoaPods. The original Podspec was contributed but the author doesn’t maintain it. enohp ym morf tnes ----------- Dan Wilcox danomatika.com robotcowboy.com

I found that using this worked to have cocoapods clone properly:

pod 'libpd', :git => 'https://github.com/libpd/libpd', :submodules => true

However, now I'm experiencing a number of duplicate symbol build errors. for example:

duplicate symbol '_libpdreceive_new' in:
    /Users/rickyd/Library/Developer/Xcode/DerivedData/app-ajeklipqnvrtccfhmglxlafpojth/Build/Intermediates.noindex/Pods.build/Debug-iphoneos/libpd.build/Objects-normal/arm64/x_libpdreceive-0aba41783a6bffe5f385d4ba8116ee8e.o

...

Seems that there are a number of classes that are defined multiple times? I'm thinking maybe it's an issue with the spec file needing to be updated to exclude files that contain the duplicates but can't say for sure.

danomatika · 2022-03-24T17:24:01Z

Yes, the x_libpd files in pure-data/src probably need to be excluded.

I don't know the rules for making a PR for the project but I forked the repo and found that updating the podspec file to this works:

I think the podspec file in Cocoapods may need to be updated too. I'm not an iOS developer though and don't really know the full process for updating pod spec files

I'd be happy to look at a PR for this, if you can make one. Maybe include the following comment line above spec.exclude_files and below the current comment:

# also exclude libpd files included with the puredata source itself for now (until parity)

corporate-fun · 2022-03-25T15:45:07Z

Got one up now: #346

danomatika · 2022-03-25T20:55:23Z

Please test the current master. If the merge is now working, then I think we can close the issue.

danomatika · 2022-03-29T00:28:59Z

I will assume this works. Please reopen if not.

andresbrocco · 2024-03-14T17:49:56Z

I was running into similar issues, because my git was unable to fetch submodules through ssh. So I've run git config --global url."https://".insteadOf git:// as proposed by berteodoseo at this post, and everything worked.
