执行3D常将中实体的pick操作,结果出现了编译错误:invalid application of 'sizeof' to incomplete type 'Qt3DRender::QPickEvent' Qt3DRender::QObjectPicker *picker = new Qt3DRender::QObjectPicker(m_sphereEntity); picker->setHoverEnabled(true); picker->setEnabled(true); connect(picker, &Qt3DRender:...
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...
使用std::unique_ptr报错:memory:error invalid application of 'sizeof' to incomplete type '***' 排查后,不使用std::unique_ptr就ok。 使用的std::unique_ptr包装的类型是在第三方库,看不到具体结构和实现,使用前置声明来包含使用的。 纠其原因,从报错可以看出: std::unique_ptr中需要静态检测类型的大小st...
error: invalid application of 'sizeof' to incomplete type 'struct PolyNode' 2、解决方案 如果你的目的是隐藏这个结构体(structure)的实现,那么你可以在可以访问到这个结构体的 C 文件(比如上面的 poly.c 文件)中这样做: structPolyNode *init_PolyNode(...){structPolyNode*P=malloc(sizeof(structPolyNode));...
Whatever thing I tried, the compiler game me errors like invalid application of ‘sizeof’ to incomplete type ‘pcap’ or like forward declaration of ‘pcap_t’ {aka ‘struct pcap’}. However, it looks like pcap_t is just a typedef for struct pcap, and I could not find the ac...
我把程序移植到了dev-c++上,错误为invalid application of `sizeof' to incomplete type `({anonymous})' 结论: 1.IAR给的错误提示不如GCC的具体,嵌入式编程遇到的问题,可以试着移植到PC上,debug相对容易 2.sizeof不能用在extern变量 为此我做了一个函数 int unpackfn_len(void) { return NELEMS(unpackfn...
invalid application of ‘sizeof’ to incomplete type sizeof 后面所跟的数据类型没有定义,或者找不到定义的地方 eg: 头文件中定义结构体如下: struct PersonaL{ char name[]; int age; }; 但是在cpp中使用时如下: struct personal a; int len = sizeof(a);...
error: invalid application of 'sizeof' to an incomplete type 'JNINativeMethod []' android studio比较奇葩得把new char[100]{"fff"}这样的直接写成字面值常量 而window 的jni则必须使用这种 -- 尴尬 然后发现2个jni文件 定义的东西不一样一个是const一个没有,这就尴尬了,我写出jni的时候跨平台测试就...
Now when it compiles, it'll have the actual type declared here during tests. Some details may have to shift depending on where you have your declarations and the types involved, etc., but I think this shows the overall gist? Best of luck!
