Compile flutter project with clang.

[shigomany]

Introduction

I would like to integrate ccache into my flutter project, but I ran into a problem when compiling.

There is also a discussion about this

In a recent release, I thought this problem would disappear thanks to this PR #3538

Platform

iOS

Environment

Production, Develop

Installed

CocoaPods

Version

8.20.0

Did it work on previous versions?

No

Steps to Reproduce

1. Change the Pod file configuration like this:

config.build_settings["CC"] = "clang"
config.build_settings["LD"] = "clang"
config.build_settings["CXX"] = "clang++"
config.build_settings["LDPLUSPLUS"] = "clang++"

2. In ios folder run:

pod update

3. In Flutter project run:

flutter build ios --no-codesign

Hello @shigomany, thanks for reaching out. Can you try the following branch in your cocoapod file to see if it solves the problem: fix/headers-out-of-strict

pod 'Sentry', :git => 'https://github.com/getsentry/sentry-cocoa', :branch => 'fix/headers-out-of-strict'

There's almost one mistake left:
