我正在尝试编译使用ChatScript库的程序。这是我在名为main.cpp的文件中的代码：
#include <iostream>
#include "common.h"
using namespace std;
char* output2;
unsigned int InitSystem(int argc,char* argv[]);
void InitStandalone();
int main(int argc, char * argv[])
{
char * userID;
userID="one";
PerformChat("one",NULL,"hi",NULL,output2);
cout<<output2;
return 0;
}
我试图包含所有的ChatScript库，我也知道performChat函数在mainSystem.h文件中，我也包含它（正如你在第218行所见：{{3 }}）。
但在尝试使用此命令编译程序后：
g++ -std=c++11 main.cpp constructCode.cpp csocket.cpp dictionarySystem.cpp english.cpp evserver.cpp factSystem.cpp functionExecute.cpp infer.cpp jsmn.cpp json.cpp markSystem.cpp mongodb.cpp mysql.cpp os.cpp outputSystem.cpp patternSystem.cpp postgres.cpp privatesrc.cpp scriptCompile.cpp spellcheck.cpp systemVariables.cpp tagger.cpp testing.cpp textUtilities.cpp tokenSystem.cpp topicSystem.cpp userCache.cpp userSystem.cpp variableSystem.cpp -o myprogram
我收到了很多这样的错误!!

使用g++ -0 test test.cpp，您可以告诉编译器编译和链接程序，但是您错过了告诉编译器在哪里可以找到用于链接的必要库。
如果你写g++ -o test.o -c test.cpp，那么编译器只会编译而不是链接，你应该得到一个有效的test.o目标文件。
然后，您可以将所有内容链接在一起。为此，从GIT存储库中加载二进制文件;我想这是LinuxChatScript64文件。比方说，将文件放在.cpp - 文件所在的同一目录中。
然后，链接：
g++ -o myprogram test.o LinuxChatScript64
希望它有效。祝你好运！

我可以用这个命令编译我的程序：
g++ -std=c++11 main.cpp constructCode.cpp duktape/duktape.cpp evserver.cpp csocket.cpp cs_ev.c dictionarySystem.cpp englishTagger.cpp factSystem.cpp json.cpp functionExecute.cpp english.cpp infer.cpp javascript.cpp jsmn.cpp markSystem.cpp mysql.cpp mongodb.cpp os.cpp outputSystem.cpp patternSystem.cpp postgres.cpp privatesrc.cpp scriptCompile.cpp spellcheck.cpp secure.cpp systemVariables.cpp tagger.cpp testing.cpp textUtilities.cpp tokenSystem.cpp topicSystem.cpp userCache.cpp userSystem.cpp variableSystem.cpp mainSystem.cpp -o myapp -L/usr/lib64 -lrt -lcurl -pthread -Ievserver -DDISCARDSERVER=1 -DDISCARDPOSTGRES=1 -DDISCARDMONGO=1 -DDISCARDMYSQL=1 -DEVSERVER=1 -DEVSERVER_FORK=1
我从makefile中找到了选项，并在我的命令末尾添加了它们，如你所见（在-o myapp之后）

您不能仅使用标题（.h）文件进行编译。头文件提供签名，但实现在对象（.o）文件中，需要由编译器链接。
