See `config.log' for more details.

知道为什么会有这样的错误吗？我已经安装了Xcode命令行工具，并且正在从终端运行configure命令

我已经安装了XCode 4.4，我非常确定已经安装了gcc，因为它提供了：

686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

我试过做：

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

但它不起作用。如果需要的话，这里有我的链接。似乎从日志中找不到gcc4.2

这怎么可能呢？

从config.log文件中，它试图使用不存在的编译器

gcc-4.2

。您需要告诉它使用一个确实存在的编译器，这通常是通过设置环境变量

CC
完成的，我刚刚编辑了.bash_配置文件，并注释掉了CC=行，因为我似乎认为它是以前安装MacPorts时留下的。
我有一行：export CFLAGS=“-arch-ppc-arch x86\u 64-g-O2-m64”在我的.profile文件中。删除-arch-ppc后，我可以成功运行./configure。
建议您可能需要选择其他gcc版本。
