Do not pass `compiler_flags` to `xcodebuild`

[mohemian-92817281]

You can declaratively specify build settings (e.g. frameworks, compiler flags) in your podspec. This is easier to maintain and replicate than build settings embedded in your Xcode project.

How would I go about doing that? I found nothing in the docs or in the help.

I would like to build a framework out of my pod with bitcode enabled and I feel stuck. I'm grateful for any hint.

The CocoaPods guides have a section for different podspec attributes

Thanks for the quick reply and pointing me in the right direction!

I found an example here. facebook.compiler_flags = '-Wno-incomplete-implementation -Wno-missing-prototypes'

So I tried to use it in my podspec file like this: s.compiler_flags = '-Wno-implicit-function-declaration'

And build the static library using pod package --library ExampleSDK.podspec

Unfortunately the build fails. Output:

Build command failed: xcodebuild GCC_PREPROCESSOR_DEFINITIONS='PodsDummy_Pods_ExampleSDK=PodsDummy_PodPackage_ExampleSDK' -Wno-implicit-function-declaration ARCHS="x86_64 i386 arm64 armv7 armv7s" CONFIGURATION_BUILD_DIR=build clean build  -configuration Release -target Pods -project Pods/Pods.xcodeproj 2>&1
Output:
    xcodebuild: error: invalid option '-Wno-implicit-function-declaration'

Thanks again for your reply.

Seems like you have found a bug with passing some custom compiler_flags.

[segiddins]

Those need to be passed as other c flags or other cpp flags

[neonichu]

Which already should be happening anyway through the generated Xcode project by CP itself, not sure why this additional code is even there.

I am using cocoapods version 0.39.0 by the way.

Edit: And cocoapods-packager-1.3.0 cocoapods-packager-1.3.0 depends on cocoapods (>= 0.38.2)

[mohemian-92817281]

Using cocoapods version 1.0.0.beta.7 I get a different error.

Command

/usr/local/bin/pod package --verbose --library ExampleSDK.podspec

I managed to achieve what I wanted to achieve by explicitly exporting OTHER_CFLAGS before running pod package.

export OTHER_CFLAGS='-fembed-bitcode' # enable bitcode
pod package --embedded ExampleSDK.podspec

Maybe this helps someone who has a similar problem. In any case, thanks again for your support and quick response.

I want to export CC and CXX env var, but I find that it doesn't work.
