I'm using CGAL , libQGLViewer libraries in a project on QT creator , Fedora 27
but it shows errors on the header file of the libraries
Compile output:

We cannot help without taking a look at the app.d. From the errors it seems that you did not import windows module that defines the various Windows-specific types.. Start with the following two typical imports:
import core.runtime;
import core.sys.windows.windows;
I strongly suggest you reading the following guide: https://wiki.dlang.org/D_for_Win32

I see the source code in gdft.c, gdhelper.h and php.h, found this line:
#ifdef HAVE_DMALLOC
#include <dmalloc.h>
#endif
it maybe dmalloc caused this error, but I don't know why the error msg show malloc.h, I checked /usr/include, it has malloc.h and dmalloc.h two files
I install the package libdmalloc and libdmalloc-dev and I try to reinstall dmalloc with sourcecode but it's not helpful
What are the causes of these and how do I deal it ?
I use Qt 4.6.3 to write application for FriendlyARM. I am trying to pass 2 pointers (pointing to classes axesParam1 and mainWin) to current class localTime but get these errors :

I did not declared setChildern to accept int* as an argument so why is it insisting on int*?
I have included the header file localtime.h
#ifndef LOCALTIME_H
#define LOCALTIME_H
#include <QWidget>
#include "axesparam1.h"
#include "mainwin.h"
namespace Ui {
class localTime;
}
class localTime : public QWidget {
Q_OBJECT
public:
localTime(QWidget *parent = 0);
~localTime();
void setChildren(axesParam1 *);
void setHome(mainWin *);
protected:
void changeEvent(QEvent *e);
private:
Ui::localTime *ui;
axesParam1 *P1;
mainWin *w;
};
#endif // LOCALTIME_H
You look too far down. Before you look at setChildern you should look into axesparam1 and/or mainwin.
localtime.h:17: error: 'axesParam1' has not been declared
localtime.h:18: error: 'mainWin' has not been declared
You have some syntex error earlier. setChildern is only some follow-up error.
In class called UserForms, I define a list (QList) or SqlQueryModel objects (subclass of QSqlQueryModel), as in this Qt tutorial.
In userforms.h:
QList<SqlQueryModel> userModels;
Then in my main code, I want to iterate over userModel, so I tried both of the following:
UserForm selectedUF = formSelectorDiag.getSelectedUF();
QList<SqlQueryModel>::iterator umIt;
for(umIt = selectedUF.userModels.begin(); umIt != selectedUF.userModels.end(); umIt++){
SqlQueryModel model = *umIt;
// Additional code removed since error happens on previous line.
}
And:
QListIterator<SqlQueryModel> umIt(selectedUF.userModels);
With both, I get a "copy constructor" error, although, I don't copy the constructor (or I don't think I do). Cf sqlquerymodel.h:
class SqlQueryModel : public QSqlQueryModel
{
Q_OBJECT
void generateRoleNames();
public:
explicit SqlQueryModel(QObject *parent = 0);
void setQuery(const QString &query, const QSqlDatabase &db = QSqlDatabase());
void setQuery(const QSqlQuery &query);
QVariant data(const QModelIndex &index, int role) const;
QHash<QString, QVariant> bindings; // Not used yet. Will be replaced by Binding class.
QString modelName;
QString query;
signals:
void bindedValueChanged();
public slots:
void search(QString);
void reset();
void updateBindings();
};

Any idea why?
QSqlQueryModel (and all other QObject-derived objects) can't be copied using copy constructor. QList requires its element type to have copy constructor. So, you need to use QList<SqlQueryModel*> instead of QList<SqlQueryModel>. You should create and delete your model objects manually using new and delete.
I am serializing the cl_long2 type from OpenCL which is defined like this (simplified from /usr/include/CL/cl_platform.hpp):
typedef int64_t cl_long;
typedef union
{
cl_long __attribute__ ((aligned(16))) s[2];
struct{ cl_long x, y; };
struct{ cl_long s0, s1; };
struct{ cl_long lo, hi; };
} cl_long2;
I defined the following stand-alone serialization function:
namespace boost{ namespace serialization {
template<class Archive> void serialize(Archive &ar, cl_long2 &i, const unsigned version){
ar & make_nvp("x",i.x);
ar & make_nvp("y",i.y);
}
}};
When I compile my code, which invokes a serialization of cl_long2 from as a class member, I am getting the following error, which I cannot understand (the error is the same if it is not a std::vector<cl_long2>, just a stand-alone variable):

/usr/include/boost/archive/detail/check.hpp:60:5: error: static assertion failed: "typex::value"
The same error appears regardless of whether the archive type is xml or binary. I am using boost::serialization 1.46.
Any hints?
**EDIT: A smaller example including error is at http://ideone.com/4UgCn
If you look at the line where the assertion fails (detail/check.hpp:60), there is a comment right above it:
// trap attempts to serialize objects marked
// not_serializable
BOOST_STATIC_ASSERT(typex::value);
The documentation of this 'not_serializable' trait says that you have to enable this long2 type first. As you found out, this is done by:
BOOST_CLASS_IMPLEMENTATION(long2,boost::serialization::object_serializable)
