pan*_*nda 3 linker compiler-errors g++ cgal
我是 CGAL 的新手,我在 Ubuntu 16.04 上使用 CGAL 4.7-4。我正在尝试编译并运行一个非常简单的 .cpp。这是代码:
#include <iostream>
#include <CGAL/Cartesian.h>
int main()
{
int p=2;
std::cout << "hello " << p << std::endl;
return 0;
}

我添加了该行
#include <CGAL/Cartesian.h>
Run Code Online (Sandbox Code Playgroud)
因为我想看看如何编译更多的库。然后我在终端上写了这一行
g++ -lCGAL -lgmp prova.cpp
Run Code Online (Sandbox Code Playgroud)
但我收到了这个错误:
/tmp/cc9DA7Ml.o:在函数'CGAL::Interval_nt::Test_runtime_rounding_modes::Test_runtime_rounding_modes()'中:

即使我写了以下任何一行,我也遇到了同样的错误:
g++ -lCGAL -lmpfr -lgmp prova.cpp
g++ -I/opt/local/include -L/opt/local/lib -lCGAL -lgmp prova.cpp
g++ -I/opt/local/include -L/opt/local/lib/ -lCGAL -lgmp prova.cpp

如果我写
g++ -lCartesian.a -lCGAL -lgmp prova.cpp
Run Code Online (Sandbox Code Playgroud)
或者
g++ -lCartesian -lCGAL -lgmp prova.cpp
Run Code Online (Sandbox Code Playgroud)
我在终端上收到此错误
/usr/bin/ld: 找不到 -lCartesian.a
collect2: 错误: ld 返回 1 个退出状态
最后如果我写
g++ -I/usr/include/CGAL -L/usr/include/CGAL -lCGAL -lgmp prova.cpp

我得到了很长的错误列表,如下所示:

我在网上看了很多,我知道编译的链接部分有问题(核心没有问题),但我真的不知道解决方案。你有什么主意吗?提前感谢您的帮助。
