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

Question

我有使用 opengl 和 CGAL 的 c++ qt 项目，但我有以下错误:

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

我搜索了关于 -DENABLE_PRECOMPILED_HEADERS=OFF 的问题和大部分解决方案我在 .pro 文件中使用它并没有解决问题。

.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

    INCLUDEPATH +=/usr/include

当我从 .pro 文件中删除 INCLUDEPATH +=/usr/include 时问题就解决了
但在到达 CGAL 时出现另一个错误：

/usr/include/boost/graph/detail/adjacency_list.hpp:1755:5: note:   template argument deduction/substitution failed:

   Sqrt3(pmesh, Sqrt3_mask_3<PolygonMesh>(&pmesh, get(vertex_point,pmesh)), step);

有什么帮助吗？

Answer 1

删除最后一行

INCLUDEPATH +=/usr/include

在 .pro 文件中

如果这不起作用，请再次尝试运行 qmake

Answer 2

我通过添加解决了问题 QMAKE_CFLAGS_ISYSTEM = -I

到 .pro 文件

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

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

c++

opengl
