本文介绍了解决使用mysql5.1 C++ API及VC6.0进行编程时遇到的编译错误“errorC2146:syntaxerror:missing';'beforeidentifier'fd'”。通过分析错误原因，发现是因为缺少winsock2.h头文件的引入，并给出了具体的解决方案。

这几天用mysql5.1 c++ api +VC6.0编程时编译器报错：error C2146: syntax error : missing ';' before identifier 'fd'

跟进mysql_com.h文件中的  my_socket fd;     /* For Perl DBI/dbd */行，发现编译器对my_socket不能识别，而在mysql.h中对my_socket有定义：#define my_socket SOCKET，那么接下来就是SOCKET定义了。SOCKET定义是在winsock2.h中，但由于加了预定义#ifdef __LCC__所以头文件winsock2.h根本没有包含进来，没办法只有自己包含了。

解决办法：在#include<mysql.h>前加上#include<winsock2.h>即可！

遇到的坑记一下 如果你遇到了这样的错误： error C2146: syntax error : missing ‘;’ before identifier error C4430: missing type specifier - int assumed. 一条C2146错误跟着一条或多头C4430错误，可以考虑检查一下是否头文件互相包含。 如 -----AFile A.h------- #include"A.h" --------------------- -----BFile B.h-------

我们正在处理一个C/C++编译错误：error C2146: syntax error : missing ')' before identifier 'a1' 根据引用[1][2][3][4]中的信息，这种错误通常是由于语法错误导致的，具体来说是在标识符'a1'之前缺少一个右括号'...

大家不用找分号了，头文件的问题，要不就是没包含windows.h，要不就是循环包含了某个头文件，要不改一下头文件的顺序就可以了。 做了个小程序，吃过了循环包含头文件的苦了
