c - Apple LLVM 编译器 4.0 报错

Question

抱歉我的英语不好，我是法国人。

我从 C 语言开始，在构建过程中遇到错误

error: -fobjc-arc is not supported with fragile abi
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

我试图在网上找到一些解决方案，但没有结果..

谢谢你帮我..

我相信发生这种情况是因为您正在使用 ARC 为 32 位 x86 编译代码。如果要使用 ARC，则必须编译为 64 位架构。
