LNK2019 错误,无法解析的外部符号
错误逐字显示
1>yes.obj : error LNK2019: unresolved external symbol "int __cdecl availableMoves(int * const,int (* const)[4],int)" (?availableMoves@@YAHQAHQAY03HH@Z) referenced in function "void __cdecl solveGame(int * const,int (* const)[4])" (?solveGame@@YAXQAHQAY03H@Z)
我以前从未见过此错误。这是我认为它所指的两个功能。
int availableMoves(int a[15], int b[36][3],int openSpace){
int count=0;
for(int i=0; i<36;i++){
if(i < 36 && b[i][2] == openSpace && isPeg(b[i][0],a) && isPeg(b[i][1],a) ){
count++;
}
}
return count;
}
和
void solveGame(int a[15], int b[36][4]) {
int empSpace;
int movesLeft;
if(pegCount(a) < 2) {
cout<<"game over"<<endl;
} else {
empSpace = findEmpty(a);
if(movesLeft = availableMoves(a,b,empSpace) < 1 ) {
temp[index] = empSpace;
d--;
c[d][0] = 0;
c[d][1] = 0;
c[d][2] = 0;
c[d][3] = 0;
a[b[c[d][3]][0]] = 1;
a[b[c[d][3]][0]] = 1;
a[b[c[d][3]][0]] = 0;
b[c[d][3]][3] = 0;
index++;
} else if(movesLeft >= 1) {
chooseMove( a, b, empSpace);
index = 0;
for(int i=0; i<4; i++) {
temp[i] = -1;
}
}
d++;
solveGame( a, b);
}
}
The error verbatim reads
1>yes.obj : error LNK2019: unresolved external symbol "int __cdecl availableMoves(int * const,int (* const)[4],int)" (?availableMoves@@YAHQAHQAY03HH@Z) referenced in function "void __cdecl solveGame(int * const,int (* const)[4])" (?solveGame@@YAXQAHQAY03H@Z)
I've never seen this error before. Here are the two functions I believe it's referring to though.
int availableMoves(int a[15], int b[36][3],int openSpace){
int count=0;
for(int i=0; i<36;i++){
if(i < 36 && b[i][2] == openSpace && isPeg(b[i][0],a) && isPeg(b[i][1],a) ){
count++;
}
}
return count;
}
and
void solveGame(int a[15], int b[36][4]) {
int empSpace;
int movesLeft;
if(pegCount(a) < 2) {
cout<<"game over"<<endl;
} else {
empSpace = findEmpty(a);
if(movesLeft = availableMoves(a,b,empSpace) < 1 ) {
temp[index] = empSpace;
d--;
c[d][0] = 0;
c[d][1] = 0;
c[d][2] = 0;
c[d][3] = 0;
a[b[c[d][3]][0]] = 1;
a[b[c[d][3]][0]] = 1;
a[b[c[d][3]][0]] = 0;
b[c[d][3]][3] = 0;
index++;
} else if(movesLeft >= 1) {
chooseMove( a, b, empSpace);
index = 0;
for(int i=0; i<4; i++) {
temp[i] = -1;
}
}
d++;
solveGame( a, b);
}
}

您当前的声明与定义不匹配。
您可能在使用函数
availableMoves()
之前声明了该函数,但随后实现了不同的函数:由于编译器首先看到该声明,因此它将使用它来解析代码块中的调用。但是,该函数不会导出,因为它具有不同的签名。
Your current declaration doesn't match the definition.
You probably have declared the function
availableMoves()
before you use it, but then you implement a different function:Since the compiler sees that declaration first, it will use it to resolve the call in the block of code. However, that function is not exported, as it has a different signature.

可能会产生问题。
in solved game
in available moves
that could create a problem.
不错:您使用了不兼容的数组维度!请注意,错误消息的一部分显示
为虽然
availableMoves()
的定义如下所示:尽管忽略参数的第一个维度,但所有其他维度必须完全匹配。但是,您尝试使用不兼容的尺寸调用此函数:
Nice one: you use incompatible array dimensions! Note that part of the error message reads
While the definition of
availableMoves()
looks like this:Although the first dimension of the arguments is ignored, all other dimensions have to match exactly. You try to call this function with incompatible dimensions, however:
