我正在编写一个具有类似矩阵结构的类,我希望有一个名为minor的成员函数与矩阵操作相同.这会触发一些错误.我系统上的最小测试用例:
#include <iterator>
void minor(int row, int col);
编译时,clang提供以下错误:
$ clang++ -Weverything -std=c++11 test.cpp
test.cpp:2:21: error: too many arguments provided to function-like macro invocation
void minor(int row, int col);
^
/usr/include/x86_64-linux-gnu/sys/sysmacros.h:67:10: note: macro 'minor' defined here
# define minor(dev) gnu_dev_minor (dev)
^
test.cpp:2:6: error: variable has incomplete type 'void'
void minor(int row, int col);
^
2 errors generated.

sys/sysmacros.h的相关部分是:
/* Access the functions with their traditional names. */
# define major(dev) gnu_dev_major (dev)
# define minor(dev) gnu_dev_minor (dev)
