我写这段代码来读取3个文件,TM是方阵的大小,LER是一个数组的行数,从最后一个值定义一个非方矩阵(ler/2)*2
然后......代码读取一个具有某种关系的文件,所有都是数字并分配给C [ler].
然后...... C [ler]被分配给B [ler/2] [2].
B [ler/2] [2]中每行的那些坐标分配给a和b.
a和b是矩阵A [tm] [tm]的行和列,其中加1.
我的代码崩溃,我不知道错误是什么.
当我尝试编译它时,编译器gcc -g -o MatSim MatSim.cpp提示:
/usr/include/c++/4.6/iostream:75: undefined reference to `std::ios_base::Init::Init()'
/usr/include/c++/4.6/iostream:75: undefined reference to `std::ios_base::Init::~Init()'
collect2: ld returned 1 exit status
另外,当我尝试编译它时,编译器f77 -o MatSim MatSim.cpp提示:
/tmp/cc6ewlkf.o: In function `__static_initialization_and_destruction_0(int, int)':
MatSim.cpp:(.text+0x17ad4a): undefined reference to `std::ios_base::Init::Init()'
MatSim.cpp:(.text+0x17ad4f): undefined reference to `std::ios_base::Init::~Init()'
collect2: ld returned 1 exit status
解
主要问题是库问题,使用以下代码编译代码:
g++ -g -o MatSim MatSim.cpp -lstdc
还是行不通？安装库:
sudo apt-get install g++-multilib
我将上一个问题中的以下代码剪切并粘贴到名为"avishay.cpp"的文件中,然后运行
gcc avishay.cpp
仅从链接器获取以下错误消息.出了什么问题,我该怎么做？
