如何将 CGAL 包含到 QT Creator 中的 QT 项目中？

发布于 2024-12-21 10:42:02 字数 153 浏览 2 评论 0原文

我正在尝试将 CGAL 中的一些示例代码作为 Qt 项目运行，以便在 Qt Creator 中运行。我预计我必须修改 .pro 文件。应该如何修改才能使用CGAL库？

我对 CGAL 并不熟悉，但一般，您需要将以下内容添加到您的 .pro 文件中：

INCLUDEPATH += /path/to/cgal/headers

LIBS += -Lpath/to/cgal/libraries -lcgal_dll_name

您可能还需要添加一些 DEFINES 如果 CGAL 需要它，即

DEFINES += SOME_MACRO_THAT_CGAL_REQUIRES

如果您专门在 CGAL 上寻求帮助，请澄清您的问题，我将删除此答案。

I'm not familiar with CGAL specifically, but in general, you would need to add the following to your .pro file:

INCLUDEPATH += /path/to/cgal/headers

LIBS += -Lpath/to/cgal/libraries -lcgal_dll_name

You may also need to add some DEFINES if CGAL requires it, i.e.

DEFINES += SOME_MACRO_THAT_CGAL_REQUIRES

If you were looking for help on CGAL specifically, please clarify your question and I will delete this answer.

虽然这是一个老问题，但为了获得更完整的答案，这就是我必须在 .pro 文件中执行的操作：

INCLUDEPATH +=   /usr/include/
LIBS        += -L/usr/include/
LIBS        += -lCGAL
LIBS        += -lgmp
LIBS        += -lmpfr // not really needed for me, but added since gmp had to be added too
QMAKE_CXXFLAGS += -frounding-math -O3

不要不要添加如下内容，它会让你遇到奇怪的错误消息的麻烦，如此链接。

INCLUDEPATH +=   /usr/include/CGAL # do NOT add this!
LIBS        += -L/usr/include/CGAL # do NOT add this!

Although this is an old question, just for the sake of having a more complete answer, this is what I had to do in the .pro file:

INCLUDEPATH +=   /usr/include/
LIBS        += -L/usr/include/
LIBS        += -lCGAL
LIBS        += -lgmp
LIBS        += -lmpfr // not really needed for me, but added since gmp had to be added too
QMAKE_CXXFLAGS += -frounding-math -O3

Do NOT add stuff like the following, it will get you into trouble with weird error messages, as discussed in this link.

INCLUDEPATH +=   /usr/include/CGAL # do NOT add this!
LIBS        += -L/usr/include/CGAL # do NOT add this!

我正在使用 Qt 4.8.6、gcc 和 Fedora 24，这是我的 Qt-CGAL 项目的 .pro ：

#-------------------------------------------------
#
# Project created by QtCreator 2017-01-08T14:50:29
#
#-------------------------------------------------    
QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = My CGAL_test
TEMPLATE = app

LIBS += -lgmp -lmpfr -lCGAL

SOURCES += main.cpp\
    mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

I'm using Qt 4.8.6, gcc and Fedora 24, and here is my .pro for Qt-CGAL projects :

#-------------------------------------------------
#
# Project created by QtCreator 2017-01-08T14:50:29
#
#-------------------------------------------------    
QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = My CGAL_test
TEMPLATE = app

LIBS += -lgmp -lmpfr -lCGAL

SOURCES += main.cpp\
    mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui
