compiler-errors - CGAL 编译器错误 : undefined reference to `CGAL::assertion_fail(char const*, char const*, int, char const*)'

Question

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;
}

我添加了行

#include <CGAL/Cartesian.h>

因为我想看看如何用更多的库编译。然后我在终端上写了这一行

g++ -lCGAL -lgmp prova.cpp

但是我得到了这个错误:

/tmp/cc9DA7Ml.o: In function 'CGAL::Interval_nt::Test_runtime_rounding_modes::Test_runtime_rounding_modes()':

prova.cpp:(.text._ZN4CGAL11Interval_ntILb0EE27Test_runtime_rounding_modesC2Ev[_ZN4CGAL11Interval_ntILb0EE27Test_runtime_rounding_modesC5Ev]+0xd2): undefined reference to 'CGAL::assertion_fail(char const*, char const*, int, char const*)'

prova.cpp:(.text._ZN4CGAL11Interval_ntILb0EE27Test_runtime_rounding_modesC2Ev[_ZN4CGAL11Interval_ntILb0EE27Test_runtime_rounding_modesC5Ev]+0x180): undefined reference to 'CGAL::assertion_fail(char const*, char const*, int, char const*)'

collect2: error: ld returned 1 exit status

即使我写了这些行中的任何一行，我也得到了同样的错误:

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

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

g++ -lCartesian.a -lCGAL -lgmp prova.cpp

或

g++ -lCartesian -lCGAL -lgmp prova.cpp

终端报错

/usr/bin/ld: cannot find -lCartesian.a

collect2: error: ld returned 1 exit status

最后如果我写了

g++ -I/usr/include/CGAL -L/usr/include/CGAL -lCGAL -lgmp prova.cpp

我得到了一长串类似这样的错误:

长长的列表是这样结束的:

return typename Real_embeddable_traits< Real_embeddable >::Is_finite()( x );

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

Answer 1

g++ prova.cpp -lCGAL

有效...看来这只是一个顺序问题。
