我在 stackoverflow 上查了很多类似的问题，但还没有找到答案。
我正在尝试在 Lion OSX 上安装 memcached 作为 shown here .
这是我得到的:
j-court-demones-macbook-pro:libevent-1.4.12-stable jcourtdemone$ ./configure; make
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... no

checking for nawk... no
checking for awk... awk
checking whether make sets $(MAKE)... yes

configure: error: in `/tmp/libevent-1.4.12-stable':
configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** No targets specified and no makefile found. Stop.
我已经按照几个地方的建议重新安装了 Xcode，但没有成功。
这是我的配置日志:

最佳答案
我安装了 10.8 和带有命令行工具的 Xcode 4.4，但仍然收到此错误。我没有重新安装 Xcode，而是注意到我的 config.log 中有两行相关的行:
configure:5130: checking for C compiler version
configure:5139: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc --version >&5
那条路对我来说并不存在。相反，我有:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain
C 编译器(“cc”)位于该 xctoolchain 目录内。我为 OSX10.8.xctoolchain 创建了一个符号链接(symbolic link)以指向 XcodeDefault.xctoolchain 并修复了它。现在memcached安装脚本可以找到编译器版本并继续前进。
cd /Applications/Xcode.app/Contents/Developer/Toolchains
sudo ln -s XcodeDefault.xctoolchain OSX10.8.xctoolchain
正如评论中所建议的，如果您在 Yosemite (10.10) 或 Mavericks (10.9) 上遇到此问题，您可以更新上面的符号链接(symbolic link)命令以指向该特定版本 (OSX10.9.xctoolchain或OSX10.10.xctoolchain)。
