问题描述

我已经使用opengl和CGAL进行了c ++ qt项目，但是出现了以下错误:

I've c++ qt project using opengl and CGAL but I've the following error:

/usr/include/c++/7/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
 #include_next <stdlib.h>

我搜索了有关-DENABLE_PRECOMPILED_HEADERS = OFF的问题和大多数解决方案 我在.pro文件中使用它，但不能解决问题.

I searched about the problem and most of solutions about -DENABLE_PRECOMPILED_HEADERS=OFF I use it at .pro file and it doesn't solve the problem .

.pro文件:

QT       += core gui opengl
QT += xml
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = try_gui
TEMPLATE = app


    DEFINES += QT_DEPRECATED_WARNINGS

    #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0


     DENABLE_PRECOMPILED_HEADERS=OFF
    SOURCES += \
            main.cpp \
            mainwindow.cpp \
        my_polyhedron.cpp \
        myqglwidget.cpp

    HEADERS += \
            mainwindow.h \
        my_polyhedron.h \
        myqglwidget.h \
        My_Halfedge_base.h \
        My_Face_base.h

    FORMS += \
            mainwindow.ui

LIBS + = -L/lib64 -lgmp -lCGAL

LIBS += -L/lib64 -lgmp -lCGAL

    INCLUDEPATH +=/usr/include

当我从.pro文件中删除INCLUDEPATH + =/usr/include时，问题已解决
但出现有关达到CGAL的另一个错误:

the problem is solved when I remove INCLUDEPATH +=/usr/include from .pro file
but another errors are appears about reaching CGAL :

有什么帮助吗?

推荐答案

我通过添加解决问题 QMAKE_CFLAGS_ISYSTEM = -I

I solve the proble by adding QMAKE_CFLAGS_ISYSTEM = -I

到.pro文件
