Description

Build for iOS fails with

with clang: error: no such file or directory: '/Users/user/Library/Developer/Xcode/DerivedData/app-eziwvgytfcyckcazzowfryoaspuu/Build/Products/Debug-appletvsimulator/libRCTAnimation.a'

libRCTAntimation seems to be linked correctly to me. I am unsure on why appletvsimulator should be an issue. This is targeted as a iPhone project.

@JonesN3 what was the problem?

[GloboM]

I'm having a similar issue with Lottie framework. This is the error i got:

'/Users/user/Library/Developer/Xcode/DerivedData/APP_RN/Build/Products/Debug-appletvsimulator/Lottie.framework/Lottie'

I'm having this issue only after updating xcode from 9.4 to xcode 10.

[sidferreira]

@GloboM Me too... Mine is with libBVLinearGradient...

[sidferreira]

trying

mxcl/PromiseKit#907

[sidferreira]

@GloboM Man, I just found in Workspace Settings an option Build System. I changed to Legacy and also changed the Derived Data to be relative. Seem that worked.

[JonesN3]

I am sorry for closing this without any solution. I have no idea what caused this or what solved it for me. I spent some hours re-building, re-linking and cleaning, and in the end it solved itself.

This solved it for me: switching to the legacy build system

[smashed-potatoes]

I had the same issue with the 'Debug-appletvsimulator' DerivedData path being used - I tracked the issue down to linking the wrong target version of the library I was using. If you run into this, make sure to select "libxxx.a from 'xxx'...." and not "libxxx.a from 'xxx_tvOS'...." when adding the link under Build Phase (where xxx is the library).

@smashed-potatoes Thanks, saved me tons of time. This actually fixes the errors instead of ignoring them.

Beware that changing to the legacy build system just ignores the errors, it doesn't actually fix them, if Apple decides to make this new build system mandatory you'll have to fix the errors anyway. I would suggest reading your errors carefully and looking for a solution like the above solution by @smashed-potatoes.
