c++ - 如何在 C++ 代码中链接 STL？

Question

我在MySql 5.5.7rc 的源文件sql_parse.cc 中写了一些代码。我在那里使用了 vector、allocator 等，但编译器未与标准模板库 (STL) 链接。谁能建议我该怎么做？

这是错误消息:

libsql.a(sql_parse.cc.o): In function `std::vector<std::basic_string<char,  
std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char,

std::char_traits<char>, std::allocator<char> > const&)':

你应该已经给出了命令行。我怀疑您使用 gcc 进行链接，在这种情况下您应该使用 g++ 或添加 -lstdc++ 选项。
