tcp - 错误: ‘TCP_NODELAY’ was not declared in this scope

我正在尝试在Ubuntu 16.04中编译ChatScipt v7.55。但是当我使用make server命令时，出现此错误:

evserver.cpp: In function ‘int settcpnodelay(int)’:
evserver.cpp:263:40: error: ‘TCP_NODELAY’ was not declared in this scope
     return setsockopt(fd, IPPROTO_TCP, TCP_NODELAY, (void*) &on, sizeof(on));
                                        ^
Makefile:110: recipe for target 'evserver.o' failed
make: *** [evserver.o] Error 1

这是命令的完整结果:

************ LINUX VERSION ************
g++ -c  -std=c++11 -Wall  -funsigned-char  -Wno-write-strings -Wno-char-subscripts -Wno-strict-aliasing  -DLOCKUSERFILE=1  -DEVSERVER=1 -DEVSERVER_FORK=1  -DDISCARDPOSTGRES=1 -DDISCARDMONGO=1 -DDISCARDMYSQL=1  -Ievserver evserver.cpp -o evserver.o
evserver.cpp: In function ‘int settcpnodelay(int)’:
evserver.cpp:263:40: error: ‘TCP_NODELAY’ was not declared in this scope
     return setsockopt(fd, IPPROTO_TCP, TCP_NODELAY, (void*) &on, sizeof(on));
                                        ^
Makefile:110: recipe for target 'evserver.o' failed
make: *** [evserver.o] Error 1

有什么问题，我该如何解决？

最佳答案

我通过在#include <netinet/tcp.h>文件的上方添加evserver.cpp解决了该问题
