openglada build problem.

openglada build problem.

[pincerfae]

I hate to be a bother, but I'm having issues with the openglada bindings.

I do everything right via the gprbuild option, as instructed in the readme.

The problem I have is when I try to build and run the included examples.

gnatmake -d -PC:\openglada\glfw_test.gpr -XGLFW_Version=2 -XLIBRARY_TYPE=static -XAuto_Exceptions=enabled -XMode=debug -XWindowing_System=windows
gnatbind -x C:\openglada\obj\glfw_test-display.ali
gnatlink C:\openglada\obj\glfw_test-display.ali -g C:\openglada\lib\libGlfwAda.a C:\openglada\lib\libOpenGLAda.a -lglfw -lwinmm -lgdi32 -lOpenGL32 -lGdi32 -o C:\openglada\bin\glfw_test-display.exe
c:/gnat/2014/bin/../libexec/gcc/i686-pc-mingw32/4.7.4/ld.exe: cannot find -lglfw
collect2.exe: error: ld returned 1 exit status
gnatlink: error when calling C:\GNAT\2014\bin\gcc.exe
gnatmake: *** link failed.

this is run within GNAT GPS..
what am I doing wrong?

libglfw.a missing?

GLFW is not standard Windows GL, AFAIK. You must install it and its 
libraries first.

and just how do I go about doing that?
I've all but given up on trying to get gl-ANYTHING to work with ada.

I've not tried openGL with Ada. But if you can't get it to build,
and want to try Fortran instead, then I have detailed instructions
how to build fortran with openGL and examples build statically that
you can download and run on linux as is. It took one 10 days of
full-time work to figure how to build Fortran with open-GL. It
is not easy, since openGL comes with many libraries and many dependencies.

This was all on Linux. On windows, no way I will even try this. Linux
is much easier to build software on.

It is a shame that the openglada demo programs depend on other
libraries.

http://flyx.github.io/OpenGLAda/ (just above the "Getting the Code"
heading) has links to GLFW, SOIL snd FTGL.At least
http://www.glfw.org/download.html contains links to Windows binaries.

A static build version could be provided, so user do not have to install
many other things to make the demo program even run. This is what I did with
the Fortran openGL. Yes, the demos are much larger in size now, but
it is only one file. Download and run. It includes inside it all
the libraries needed linked in statically.

Having to download many other libraries just to see a demo program,
will discourage people from even trying it.

well said, nasser.
I like learning ada, a lot. but this whole patchwork of getting anything to work is very discouraging.
delphi/pascal and opengl isn't much better, as I've found.

I'm sorry but it's seriously not difficult if you know how to use the
tools. You need to look at he gnat options. This is not m$'s c++ IDE where
everything is done for you.

and WHERE did I mention anything about C/C++? Oh wait, I didn't, did I?
lose the goddamned attitude. 



I downloaded the glfw, with no clue on where to install the files, because there's NO INSTRUCTIONS on where to put them.
This has been my problem. I view the readme for every opengl binding I've downloaded (as there are only three), and I still get error messages about 'missing -lgfw'. WHEN I AM ACTUALLY USING THE GNAT COMPILER...

The main issue I am seeing (and have been seeing for quite a while), is that a lot of these so-called bindings seem to be written and packaged for people running *nix systems, and not windows (WHICH IS WHAT I'M USING).

until you can say something that'll actually help me towards resolving this problem, refrain from saying anything further.


I downloaded glfw after receiving the -lglfw not found message when trying to gprbuild in msys.
nothing from the examples will build (which obviously includes using GNAT/GPS(DUH!), because it's missing glfw.

The problem is there lacks any specifics on where to put the contents of glfw or where to add it as a reference to solve this problem.

it was mentioned before, that Ada seems to favour anything that's NOT a Windows OS.

There should be a disclaimer. You can use Ada with OpenGL as long as it's not using a Windows OS.

If you have nothing helpful to offer, MOVE ON...


I am fed up of seeing this meessage every time I want to see ANY examples in felix krause's opengl binding.

gnatmake -d -PC:\openglada\glfw_test.gpr -XGLFW_Version=2 -XLIBRARY_TYPE=static -XAuto_Exceptions=enabled -XMode=debug -XWindowing_System=windows glfw_test-display.adb -j2
gnatbind -x C:\openglada\obj\glfw_test-display.ali
gnatlink C:\openglada\obj\glfw_test-display.ali -g C:\openglada\lib\libGlfwAda.a C:\openglada\lib\libOpenGLAda.a -lglfw -lwinmm -lgdi32 -lOpenGL32 -lGdi32 -o C:\openglada\bin\glfw_test-display.exe
c:/gnat/2014/bin/../libexec/gcc/i686-pc-mingw32/4.7.4/ld.exe: cannot find -lglfw
collect2.exe: error: ld returned 1 exit status
gnatlink: error when calling C:\GNAT\2014\bin\gcc.exe
gnatmake: *** link failed.

all this just to be able to view an example of a binding. unacceptable.

glfw is on my drive. according to

Binding cannot install things they are bound to.

But you need a [static/import] *library* of.

The library must be located on the library path used by the gcc and so
ultimately by GNAT. This has little to do with Ada or bindings. If you
don't have it on the path you must ensure that the gcc switch
-L<library-path> appears *before* -lglfw. There are dozens different way to
achieve linking to a certain library. Sorry for repeating but this is a
routine when working with gcc.
