我正在使用ndk编译我的项目，我想使用c++_static来构建我的项目。为此我正在使用 -
APP_STL := c++_static
并且
APP_CPPFLAGS := -std=c++11 -pthread -frtti -Wno-format-extra-args -Wno-format-zero-length -Wdeprecated-declarations -fno-builtin-cos -fno-builtin-sin -fno-builtin-cosf -fno-builtin-sinf -fexceptionsin
在Application.mk
但是这给了我错误：

请帮我解决这个问题。之前我使用gnustl_shared构建了我的项目，它工作正常，但由于某些约束，我需要使用c++ static或c++_shared构建我的项目。

使用LLVM libc ++ STL包含<complex>时遇到了同样的问题。一个解决方案＆＃39;对我有用的是在ndk-bundle/sources/cxx-stl/llvm-libc++/include/cmath中注释掉这些特定的行。
答案 1 :(得分：1)
NDK中的std lib不太可能出错。
我最近遇到过类似的问题，有精确的堆栈但有不同的NDK版本（16b）。 我试图用cmake编译愚蠢。
原来我在包含路径中有“-I src / folly / folly”文件夹，并且由于某种原因cmake没有把系统包括在内。
编译器在folly文件夹中查找<math>和其他系统库。
一旦我从包含列表中删除了这个文件夹，问题就消失了。
