我在跟踪these instructions编译名为SDPB的程序时遇到问题。总而言之，我在Mac OS X Yosemite上安装了一个需要Boost，GMP和OpenMP的程序。所有单独的代码片段都会编译，但是当它的链接时间到来时，我得到Undefined symbols for architecture x86_64。
我的问题与this question基本相同。但是，我无法得到那里的答案为我工作。我仍然得到同样的错误。
经过更多的搜索，我看到有类似问题的人得到的答案指出了clang和gcc之间的冲突。更具体地说，混合库libstdc ++和libc ++存在问题。
因此，我确保使用gcc重新编译Boost和GMP，以便使用libstdc ++构建所有内容。这没有用。然后我下载了一个与OpenMP兼容的clang实现，并尝试使用libc ++构建所有内容。这也行不通。然后，我使用带有-stdlib=libstdc++标志的clang尝试了各种排列，依此类推。似乎没什么用。错误的细节似乎随着各种变化而有所改变。我将在下面发布几个片段。当然，我总是使用更新的makefile来编译SDPB，我总是使用--enable-cxx标志配置GMP作为上面链接的答案。
这里是我在用gcc编译GMP和Boost后用gcc编译SDPB时收到的错误的片段。
