error: invalid use of incomplete type error: invalid use of incomplete type 一. 首先,要确定自己定义的类是完整的,构造函数,析构函数都有,函数的声明及定义分开在.h和.cpp中实现。 如果确定类是完整的,仍然出现error: invalid use of incomplete type的报错,那么问题出现在该类的使用上,而不是类的实现上....

When I define the test() method outside of the class, the compiler gives me a "invalid use of incomplete type" error, but it works fine when the function is defined inline. I am defining the entire class and the definitions in the same file, so why is it giving me this error? La...
Re: Trying to change SPI driver compile error "error invalid use of incomplete type 'spi_t'" Postbythemindfactory»Tue Dec 10, 2019 5:48 pm I think this is happening as spi_struct_t is not defined in any .h files, its defined within a .c file, so the compiler does not know th...
简而言之,所谓"struct tcphdr"是一个来自外部的被include的库文件的结构体.而且它这个结构体的构造有点诡异.我不知道什么是__extension__ union,这会让它更难处理吗? struct tcphdr { __extension__ union { struct { uint16_t th_sport; /* source port */ uint16_t th_dport; /* destination port...
