After successful compilation with my make file, I attempt to run my python script and I receive an import error on my extension module (the c++ code) that reads "undefined symbol: _ZN5AgentC1Effff". All the boost-python stuff aside, I believe this to be a simple c++ linker error. Here...

这是因为你在调用函数ad之前没有事先声明。这样就可以了。include <stdio.h> int ad(int a,int b);main(){ int x,y,m;printf("Input x,y;");scanf ("%d%d",&x,&y);printf ("%d",ad(x,y));} int ad (int a,int b){ return (a+b);} ...

这是由于没有链接入绘图库导致的,Turbo C 2.0 需要这样设置:菜单 -> Options -> Linker -> Graphics library 设置为 On。Turbo C 3.0 需要这样设置:菜单 -> Options -> Linker -> Libraries,选中 Graphics library 再点 OK。再编译就不会遇到这个问题了。参考资料:http://tieba.baidu....
这个提示的意思是print符号没有定义。你程序中肯定错写了。你看看你的倒数第一个case语句:case 1:print("%d\n",indiv); 这句里面的printf你写成了print。少了个f,所以会出现错误
Linker Error:Undefined symbol '_main' in module cos 是说程序里没有 main 函数 c 程序里必须有 main 函数才行,程序从 main开始运行
main函数没有定义啊 include <stdlib.h>//其中有exit的说明 include <stdio.h>//其中有标准错误stderr的说明 void Error(char * message){ fprintf(stderr,"Error:%s\n",message);//输出错误信息 exit(1);//终止程序,返回1给操作系统 } main(){Error(*message);} //第二次回答 你给的...
建议你把extern写到main外面 直接命令行输入 tcc f1.c f2.c 就可以了 extern其实写不写都无所谓,只有变量才需要写extern。比如你写了一个全局变量在f1里面,f2里面要用必须写extern。函数你不写就表示extern。你不声明就调用,隐含extern int。
