Remove ALWAYS_SEARCH_USER_PATHS=YES from podspec?

[toreolsensan]

I'm using CorePlot 2.2 in my project. After doing pod install, building in Xcode 8.1 gives me the following warning:

warning: using 'ALWAYS_SEARCH_USER_PATHS = YES' while building targets which define modules ('DEFINES_MODULE = YES') may fail. Please migrate to using 'ALWAYS_SEARCH_USER_PATHS = NO'.

I tracked the source of this setting to CorePlot, and managed to get rid of the warnings by changing the setting to NO locally by doing pod spec edit CorePlot before rebuilding pod install/Xcode build.

Would you consider changing this setting? I suspect that commit 114de15 which reintroduced this setting didn't really need to, and that adding the HEADER_SEARCH_PATHS would be enough in that case, but I haven't really investigated this.

This isn't a big deal, but having fewer build warnings is always nice.

That setting was added to fix issue #243 last year. I'm not sure if its still needed with newer versions of Xcode in some situations.

I was able to reproduce this problem in my Cocoapods test project with Xcode 8.2. I fixed it by overriding the "Always Search User Paths" setting in the app to "No". Does that work for you? Note that you need to change the setting at the target level—Cocopods uses an .xcconfig file that overrides the project-wide setting.

Thanks for taking your time to respond to this! You are correct that the warnings go away if you override the setting on the target in Xcode. However that causes pod install to complain:

[!] The `MyProject [Debug]` target overrides the `ALWAYS_SEARCH_USER_PATHS` build setting defined in `Pods/Target Support Files/Pods-MyProject/Pods-MyProject.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

Perhaps that's preferrable since it's not run so often but I still wonder if reintroducing ALWAYS_SEARCH_USER_PATHS=YES in that bugfix was strictly needed…

Xcode 8.3, released today, indicates that ALWAYS_SEARCH_USER_PATHS is now deprecated:

The "Always Search User Paths" build setting is deprecated and may not be supported by a future version of Xcode. Projects which are relying on this feature should migrate to separate user vs. system header include semantics and set this build setting to "No". (16364329)

By virtue of Core Plot forcing this setting, our project always emits several annoying compiler warnings on build. Seems like no better time to get rid of this.

Fixed on the release-2.3 branch.

hey, what status has 2.3? Will it ever be released?

[eskroch]

I'll release it after the final version of Xcode 9 is released this fall.

Any update?

I'm working on resolving the last open pull request. I'll finalize the release after that is taken care of.

Hey, I hit this issue today, any update on this? 🙂
