中的错误当<字符串>时包含在内
_gnu_cxx::snprintf has not been declared
当我在我的 cpp 中包含字符串时。此错误位于此行：
using ::__gnu_cxx::snprintf;
cstdio 是按此顺序包含的：
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/string:47,
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/bits/char_traits.h:46,
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/bits/stl_algobase.h:70,
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/iosfwd:45,
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/iosfwd:45,
_gnu_cxx::snprintf has not been declared
when I include string in my cpp. This error is in on this line:
using ::__gnu_cxx::snprintf;
cstdio is include in this order:
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/string:47,
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include/c++/4.2.1/bits/char_traits.h:46,

我通过在标题中添加 #define _GLIBCXX_USE_C99_DYNAMIC 1 解决了这个问题。
I solved this by adding #define _GLIBCXX_USE_C99_DYNAMIC 1 in my header.
