在 Linux 机器上，我的代码可以成功构建。
但是，在我的 Mac 上，除非我删除这部分，否则无法构建相同的命令:
void split_is(const std::string &s, string delim_regex, std::vector<std::string> &elems) {
// Terribly slow and inefficient, sorry. Should probably fix this at some point
boost::algorithm::split_regex(elems, s, regex(delim_regex));
std::vector<std::string> non_zero_elems;
for(int e = 0; e < elems.size(); e++){
if (elems[e].length() > 0){
non_zero_elems.push_back(elems[e]);
}
}
elems = non_zero_elems; }
我使用的命令是:
g++ -lboost_regex -lgurobi_c++ -lgurobi60 -stdlib=libstdc++ -lpthread
-lm -Wall -m64 -fPIE -fexceptions -frounding-math -O2 -I/Library/gurobi604/mac64/include/ -I/usr/local/include/ -L/Library/gurobi604/mac64/lib/ -L/usr/local/lib/ main.cpp tools.cpp treeofdevil.cpp solver.cpp periodicfunction.cpp -o ising.exe /usr/local/lib/libboost_regex.a
有谁知道可能会出现什么问题？谢谢。
我得到的错误是:

最佳答案
我怀疑您在这里发生的不止一件事；移动 -lboost_regex 应该可以解决其中的一些问题。
我怀疑您遇到的主要问题是您已经使用 libc++ 构建了部分程序(可能是 boost 库)，而其余部分使用了 libstdc++。
您的构建命令明确指出 -stdlib=libstdc++，但错误消息提到了 std::__1::....，这是 libc++ 中存在的地方.
关于c++ - 在 MacOS 上 boost 正则表达式构建失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31573031/
