多定义C ++ / C谷歌测试

所以我看到了类似的问题，我按照他们说的去做。我已经确保我的.h和.cpp文件在我的主测试文件中。

所以我真的不确定出了什么问题。我修复了这样的早期错误，但这是我抓住的。我感谢一些帮助。

矩阵乘法.h

Matrix-Multiply.h
#ifndef __MATRIX_MULTIPLY_H
#define __MATRIX_MULTIPLY_H  
#include<stdio.h>
#include<stdlib.h>

float *expectedFinalMatrixOutput(int mA,int nA,int mB,int nB,float *matA,float *matB);
int readFiles(const char *matAFile,const char *matBFile);

#endif //__MATRIX_MULTIPLY_H

矩阵乘法.cpp

//.cpp file
#include<stdio.h>
#include<stdlib.h>
float *expectedFinalMatrixOutput(int mA,int nA,int mB,int nB,float *matA,float *matB)
{
int m = mA;
int n = nB;
int size = m * n;
float *finalMatrix[size];
//build both matrices
//for both the matA Column and matB Row need to be the 
//same before even multiplying
//dot product matrix
//the end matrix needs the have the same number of rows as 
//matA and same number of columns as matB
return *finalMatrix;
}
int readFiles(const char *matAFile,const char *matBFile)
{
int flag;
//read in file for matrixs
//set flag for whether true or false
//verify row and column being taken have actual values and 
//that the sized are correct
return flag;
}

基质Multiply_unittests.cpp

// tests.cpp
#include "Matrix-Multiply.h"
#include "Matrix-Multiply.cpp"
#include<gtest/gtest.h>
#include<stdio.h>
TEST(matrixSize,emptyMatrix)
{
float *matA = NULL;
float *matB = NULL;
float *matrix = 
expectedFinalMatrixOutput(0,0,0,0,matA,matB);
ASSERT_EQ(*(matrix),0);
}
TEST(dotTest,oneByoneMatrix) 
{
float fMatrix[1] = {1};
float sMatrix[1] = {1};
float *matrix = expectedFinalMatrixOutput(1,1,1,1,fMatrix,sMatrix);
ASSERT_EQ(matrix[0],1);
}
TEST(dotTest,twoBytwoMatrix)
{
float fMatrix[4] = {1,1,1,1};
float sMatrix[4] = {1,1,1,1};
float *matrix = expectedFinalMatrixOutput(2,2,2,2,fMatrix,sMatrix);
for(int i =0;i<4;i++)
{
EXPECT_EQ(2,matrix[i]);
}
}
TEST(ReadFilesTest,filesExist)
{
const char *matA = "../src/Matrix1_3_3.txt";
const char *matB = "../src/Matrix2_3_3.txt";
ASSERT_EQ(0,readFiles(matA,matB));
}
TEST(ReadFilesTest,filesDontExist)
{
const char *matA = "../src/notReal.txt";
const char *matB = "../src/Matrix2_3_3.txt";
ASSERT_EQ(0,readFiles(matA,matB));
}
TEST(ReadFilesTest,matrixSizeNotCompatible)
{
const char *matA = "../src/Matrix1_3_3.txt";
const char *matB = "../src/Matrix2_2_2.txt";
ASSERT_EQ(0,readFiles(matA,matB));
}
int main(int argc,char **argv)
{
testing::InitGoogleTest(&argc,argv);
return RUN_ALL_TESTS();
}

抱歉，如果它不是全部在一行上。我试着这样想。但我得到的错误是：

obj/Matrix-Multiply.o: In function `expectedFinalMatrixOutput(int, int, int, 
int, float*, float*)':
Matrix-Multiply.cpp:(.text+0x0): multiple definition of 
`expectedFinalMatrixOutput(int, int, int, int, float*, float*)'

collect2: error: ld returned 1 exit status

我正在使用谷歌测试，并且已经打电话进行gtest 但是，当我调用 make test 时会发生此错误。

任何帮助不胜感激
