【问题描述】:
我是 CGAL 的新手,我在 Ubuntu 16.04 上使用 CGAL 4.7-4。 我正在尝试编译和运行一个非常简单的.cpp。代码如下:
#include <iostream>
#include <CGAL/Cartesian.h>
int main()
{
int p=2;
std::cout << "hello " << p << std::endl;
return 0;
}
我加了一行
#include <CGAL/Cartesian.h>
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
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:
prova.cpp:(.text._ZN4CGAL11Interval_ntILb0EE27Test_runtime_rounding_modesC2Ev[_ZN4CGAL11Interval_ntILb0EE27Test_runtime_rounding_modesC5Ev]+0xd2): 未定义引用 'CGAL::assertion_fail(char const*, char const*, int, char const*)'

collect2: 错误:ld 返回 1 个退出状态
即使我写了以下任何一行,我也会遇到同样的错误:
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
g++ -I/usr/include -L/usr/bin -lCGAL -lgmp prova.cpp
g++ -I/usr/bin -L/usr/lib -lCGAL -lgmp prova.cpp
如果我写了
g++ -lCartesian.a -lCGAL -lgmp prova.cpp
或
g++ -lCartesian -lCGAL -lgmp prova.cpp
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
如果我写到最后
g++ -I/usr/include/CGAL -L/usr/include/CGAL -lCGAL -lgmp prova.cpp
我收到了一长串类似这样的错误:

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。
