我想用我构建的两个测试编译node.c,list.c和helper-functions.c。链接C和C++文件

我敢肯定,我没有写我的makefile,因为我应该。你可以检查一下吗?

CFLAGS= -Wall -Wvla -Werror 
CXXFLAGS= -lgtest -lgtest_main -pthread 

all: 
    mkdir -p build 
    gcc -c node.c $(CFLAGS) -o build/node.o 
    gcc -c list.c $(CFLAGS) -o build/list.o 
    gcc -c tests/helper-functions.c -o build/helper-functions.o 
    g++ tests/node-tests.cpp $(CXXFLAGS) -o build/node-tests.o 
    g++ tests/list-tests.cpp $(CXXFLAGS) -o build/list-tests.o 
    g++ build/list.o build/node.o build/helper-functions.o build/node-tests.o build/list-tests.o -o build/tests.out 
    ./build/tests.out 

当我跑make,输出为:

mkdir -p build 
gcc -c node.c -Wall -Wvla -Werror -o build/node.o 
gcc -c list.c -Wall -Wvla -Werror -o build/list.o 
gcc -c tests/helper-functions.c -o build/helper-functions.o 
g++ tests/node-tests.cpp -lgtest -lgtest_main -pthread -o build/node-tests.o 
/tmp/ccFTgPVe.o: In function `CreateNode_FirstTest_Test::TestBody()': 
node-tests.cpp:(.text+0x21): undefined reference to `createNode' 
node-tests.cpp:(.text+0x31): undefined reference to `data' 
node-tests.cpp:(.text+0x108): undefined reference to `next' 
node-tests.cpp:(.text+0x1db): undefined reference to `freeNode' 
collect2: error: ld returned 1 exit status 
make: *** [all] Error 1 

有definitly在节点TEST.CPP所有这些函数的参考。

节点tests.cpp:

extern "C" 
{ 
    #include "../../../../headers/list.h" 
    #include "../../../../headers/node.h" 
    #include "helper-functions.h" 
    #include <assert.h> 
} 
#include "gtest/gtest.h" 
#include <iostream> 
#include <cstdlib> 
#include <string> 


// Node* CreateNode(void* data,const size_t dataLength,void* deepCopy(void*,const size_t)); 

TEST(CreateNode, FirstTest) { 

    int x=10; 
    Node* pos=createNode(&x,sizeof(x)); 
    EXPECT_TRUE(*(int*)data(pos)==x); 
    EXPECT_TRUE(next(pos)==NULL); 
    freeNode(pos); 
} 

的列表tests.cpp类似于节点tests.cpp。

如果我写了它,你可以检查我的makefile吗?如果不是请参考相关答案,因为其中有27个。 –

我们不是免费的调试服务。重复应回答你的问题。如果没有,请说明**特定问题**,以及它与dup中的问题有何不同。 – Olaf
