前段时间我安装了osx-gcc-installer。在我尝试使用自制软件安装opencv之前，这不是问题。 Brew医生抱怨osx-gcc-installer，所以我卸载了命令行工具，xcode和osx-gcc-installer的每个标志。
现在当我再次安装xcode以及命令行工具时，我不断遇到相同的错误。以下是尝试安装webp的输出（我的酿造医生说我需要）。非常感谢任何帮助：
终端输出

和config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by libwebp configure 0.4.0, which was
generated by GNU Autoconf 2.68. Invocation command line was
$ ./configure --disable-dependency-tracking --enable-libwebpmux --enable-libwebpdemux --enable-libwebpdecoder --prefix=/usr/local/Cellar/webp/0.4.0_1

编辑： 经过一些调查后，我想我的/ usr / bin / ld可能有问题：
$ /usr/bin/ld
ld: warning: -arch not specified
ld: warning: -macosx_version_min not specificed, assuming 10.7
ld: no object files specified for inferred architecture x86_64
操作系统不是我的强项，所以我可能会偏离主题。希望这有助于拥有更多操作系统知识的人。
EDIT2：
尝试从config.log输出编译测试代码会导致以下结果：

答案 0 :(得分：0)
这是一个奇怪的情况，当然是我从未遇到的具体情况。我已经看到了ld的问题，特别是在Xcode 5.x和一些旧的/替代架构之后。因此，它远非理想，但我不怀疑以下相关的解决方法可能会让您启动并运行。
