Architecture 使用Qt Creator编译CGAL时出错

我在Qt Creator中尝试使用CGAL编译一些代码时出错

这是我的.pro文件：

QT       += core

QT       -= gui

TARGET = TestCCGALAppliConsole
CONFIG   += console
CONFIG   -= app_bundle
CONFIG   -= x86_64
CONFIG   += i386

TEMPLATE = app

INCLUDEPATH += /opt/local/include
LIBS        += -L/opt/local/include

SOURCES += main.cpp



win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../opt/local/lib/release/ -lCGAL
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../opt/local/lib/debug/ -lCGAL
else:unix: LIBS += -L$$PWD/../../../opt/local/lib/ -lCGAL

INCLUDEPATH += $$PWD/../../../opt/local/include
DEPENDPATH += $$PWD/../../../opt/local/include


win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../opt/local/lib/release/ -lCGAL_ImageIO
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../opt/local/lib/debug/ -lCGAL_ImageIO
else:unix: LIBS += -L$$PWD/../../../opt/local/lib/ -lCGAL_ImageIO

INCLUDEPATH += $$PWD/../../../opt/local/include
DEPENDPATH += $$PWD/../../../opt/local/include

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../opt/local/lib/release/ -lCGAL_Core
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../opt/local/lib/debug/ -lCGAL_Core
else:unix: LIBS += -L$$PWD/../../../opt/local/lib/ -lCGAL_Core

INCLUDEPATH += $$PWD/../../../opt/local/include
DEPENDPATH += $$PWD/../../../opt/local/include

当我有了这段代码（这只是一个示例），它就可以工作了

#include <iostream>
#include <CGAL/Simple_cartesian.h>
#include <CGAL/Exact_predicates_exact_constructions_kernel.h>

typedef CGAL::Simple_cartesian<double> Kernel;
typedef Kernel::Point_2 Point_2;
typedef CGAL::Exact_predicates_exact_constructions_kernel Kernel2;
typedef Kernel2::Point_2 Point_2_2;

int main()
{
   // Point_2_2  p1(0, 0.3), q1(1, 0.6), r1(2, 0.9);
  {
    Point_2 p(0, 0.3), q(1, 0.6), r(2, 0.9);
    std::cout << (CGAL::collinear(p,q,r) ? "collinear\n" : "not collinear\n");
  }
  {
    Point_2 p(0, 1.0/3.0), q(1, 2.0/3.0), r(2, 1);
    std::cout << (CGAL::collinear(p,q,r) ? "collinear\n" : "not collinear\n");
  }
  {
    Point_2 p(0,0), q(1, 1), r(2, 2);
    std::cout << (CGAL::collinear(p,q,r) ? "collinear\n" : "not collinear\n");
  }
  return 0;
}

std:：无法显示实际执行的命令行以及完整的错误消息。您可能缺少
-lmpfr-lgmp
。如果您使用它，CMake将为您处理。我直接在Qt Creator中编译，这是完整的错误消息。我添加了
-lmpfr-lgmp
，但它无法解决问题。您报告的错误是太短。请尝试找出找不到的符号。它应该是完整编译日志中的某个内容。我终于解决了这个问题，添加了
-lmpfr-lgm
，它几乎适用于所有内容，但是，当我使用
时，我遇到了相同的错误，只有当我使用此标题时……我认为我发现了问题
