需求
今天编译时,报错: =error: binding reference of type ‘CalibrationVoltage::RefFloat_kParamNum’ {aka ‘float (&)[3]’} to ‘const float [3]’ discards qualifiers=, 我觉得很奇怪,我明明加了 const 了,为啥还是说没有 const 呢?
using RefFloat_kParamNum = float (&) [kParamNum];
RefFloat_kChannelNum_kParamNum CalibrateParam(const RefFloat_kParamNum output);
解决
怀疑是因为 const
和 using
一起作用的结果,所以稍微修改了一下,就
ok 了。根本原因要等后续再查了。
using RefFloat_const_kParamNum = const float (&) [kParamNum];
RefFloat_kChannelNum_kParamNum CalibrateParam(RefFloat_const_kParamNum output);
参考
C++编译出现binding ‘const string {aka const std::__cxx11::basic_string<char>}’ to reference of type ‘std
