It seems MathGL doesn't have their internal
#include statements in order, and require you to be careful about what you
#include and in what order. In particular, ensure you
#include before any other MathGL header, and before that one ensure you
#include . Futhermore, when you use for example Qt-related functions, ensure you
#include . This should work:
I try to make
mathgl work, but the linker can't find the library. I installed it through the user repository from arch linux.
I just copied the example program:

HomogRotate3D creates a 3D rotation Matrix that rotates by (radian) angle about some arbitrary axis given by a Normalized Vector.
I wanted to program a custom OpenGL Widget inside a QML application to plot data with MathGL.
To do this i took a look at the Scene Graph example at http://doc.qt.io/qt-5/qtquick-scenegraph-openglunderqml-example.html
I then adapted the code to my needs and then the problem occurred, that the Image only flashes one rendercycle and after that doesn't appear anymore. Following are the important functions and bindings.
class GLRenderEngine : public QObject, public QOpenGLFunctions...

To solve this problem i switched to the QQuickFrameBuffer implementation and removed any glClear commands i had been using inside the render function, while the Clear Flag of the base class QQuickItem is enabled. It now works like a charm.
I am trying to use MathGL in my project. When i go through the package contents i can only find .a static library files, how can i use those to include that library in my Visual Studio project?
I have tried to include all the .a files by going to Project Properties->Configuration Properties->Linker->Input
and link all the .a files using "additional dependencies". But then i still get a ton of errors when i include the mgl.h file.
I guess my question is: is the way to use a library in your program is to include the needed .a files? and if yes, what is the correct way to do it?...

According with the documentation of MathGL, the libraries are into the directory mathgl/lib, and they are dinamic link libraries(dlls):
The same documentation says:
Use a precompiled binary. There are binaries for MinGW (platform Win32). For a precompiled variant one needs only to unpack the archive to the location of the Chapter 1: Overview 3 compiler (i.e. mathgl/lib in mingw/lib, mathgl/include in mingw/include and so on) or in arbitrary other folder and setup paths in compiler. By default, precompiled versions include the support of GSL (www.gsl.org) and PNG. So, one needs to have these libraries installed on system (it can be found, for example, at http://gnuwin32. sourceforge.net/packages.html).
So, you need to link the Dll instead of a static library, check this asnwer to see how to link a dll: Linking dll in Visual Studio
I am kind of new to C++ (used to be a Java developer, where this is way easier...) and I have to write an application, which has to plot some graphs and charts. To do so I want to use the MathGL library. And I learned, that I have to compile it myself in order to use it. So that's what I'm trying to do the last few days...
I am using Windows with MinGW and the CLion IDE. I started by extracting MathGL's source code into a folder and opening the folder with CLion. Then I downloaded the source codes of zlib and libpng and set the INCLUDE_DIR variables in the MathGL project to the respective folders and PNG_PNG_LIBRARY to png32. When I try to compile mgl_example via CLion it gives me the following error:...
ANSWERAnswered 2017-Apr-09 at 13:07
It looks like that missing header file is generated after running a configure for libpng (which under Windows you may be unable to do and need to generate yourself -> Cannot open include file: 'pnglibconf.h':No such file or directory)
But besides that, how did you get the impression that you need to build it from scratch in order to use it? You can also download the precompiled binaries and link them with your program (http://mathgl.sourceforge.net/doc_en/Installation.html - point 2).
edit: Looking at your edit, you need to specify the actual library file in Windows (probably something along the lines of png32.a or whatever your libpng compilation generated), assuming the linker also has the path where the library file is (see http://www.mingw.org/wiki/specify_the_libraries_for_the_linker_to_use)
