I'm trying to just build webkit on windows. As usual I started with webkit site and trying to get developer tools setup. I'm struck basically at the cygwin Installation itself.
The cygwin-downloader gets all the packages and runs the setup normally.
As per the installation instructions, I selected the Install from Local Directory Option (cygwin install and source package directories are different).
There was some initial turbulance in finding the packages, somehow i could let it find the packages. The screen looks like this now.
I selected the packages (all) and then proceeded with next. It just ran very fast and exited saying nothing needs to be installed. It looked like this.
After I ran the cygwin shorcut from the desktop its shouting something is missing.
I don't understand what am I missing here. Also at some link it says we need a port to build webkit. If thats the case, how does anyone port webkit to their applications without building the webkit alone?
I know this is not a programming question. but this will help most of the people who are taking baby steps in understanding and build WebKit. Thanks!
According to this, it's seems a cygwin-downloader's bug.
However, there is a workaround...
Just copy {cygwin-downloader}\setup.ini file to a {cygwin-downloader}\x86\ directory. Then reopen setup.exe. It will show you a package list without turbulence. You don't need to click all from the package list. Just click Next.

I want to build a GUI for some fortran code I have. GTK-Fortran seemed like a simple option, but I'm having trouble getting everything installed in the correct place.
I am using Windows 8. I have gfortran (version 4.8.1), Cmake, and GTK+ 3 installed. As far as I can tell, the last thing I need to do is include GTK-Fortran, which I download from https://github.com/jerryd/gtk-fortran (the link to download the .zip file is on the right side of the page), but all of the instructions on what to do with it are incredibly vague to me. The INSTALL instructions seem to want me to make a new directory, C:\build, and then do something with cmake, but I'm not sure what that something is or how to do it.
I have GTK+ 3 in C:\GTK, and its bin is included in the path. I would like to just put the GTK-Fortran files within the GTK folder, but I don't think that will actually give me access to the GTK-Fortran files.
Could someone give me very clear instructions on what to do with the files for GTK-Fortran so that I can call them from my own fortran code?
The simplest way for using gtk-fortran under Windows is to install MSYS2/MINGW64, following the installation steps described in the wiki of the project:

I've been having a problem with including Shoes in a Shoes app for Windows. The packager tool works perfectly when I don't ask to include Shoes in the app: I get an .exe that, if launched on a Shoes-less computer, downloads Shoes and then runs as expected.
However, when I ask it to include Shoes, the packager seems to get stuck on something from the get-go. At least, in some other cases, the packager does make an executable, even if it didn't contain Shoes. Here, it just freezes.
I even tried the solution proposed here, but I couldn't manage building shoes. After cloning the rubyinstaller repository and downloading the requisite elements, the rake command aborts prematurely.
Installer may be a corrupted one
or may contains some missing files.
So,its better to download another and try again.
May be installer itself is buggy. Try other packaging software. The great one for Windows is NSIS here.
It has a simple scripting which will help you to make your installer more adaptive.
And you could search an old version of this product.
I am trying to install the latest SVN Update OpenSceneGraph-3.1.4 on Mac OS X Mountain Lion.
Do I need to install a specific WindowSystemInterface ?
$ osgviewer cow.osg
View::setUpViewAcrossAllScreens() : Error, no WindowSystemInterface available, cannot create windows.
Viewer::realize() - failed to set up any windows.
I build and re-build many times, using CMake with or without Gui, compiling Unix files or from within Xcode, but still same problem.
Thank you!
If you'd like a more recent Mac OSG binary which includes a
user-runnable installer, OSG Frameworks supporting both 32 and 64-bit
archs, etc. you can use the one published by ARToolworks:
http://www.artoolworks.com/dist/openscenegraph/3.1.x/
It doesn't include the COLLADA (.dae) plugin but most other plugins
are present.
Regards, Phil.
It sounds like somehow the GraphicsWindow*.cpp file didn't compile and link and execute, as this is what provides the WindowSystemInterface. This is an unusual condition, as normally this is built automatically, linked in and executed as the library starts up and the user is never the wiser.
I'm not sure what to advise you, only to re-check you build process as something has gone very wrong.
I've tried to use MonoDevelop 2.4 and 2.6 with Ubuntu 11.04, but neither of them seems to actually provide any way of running the project. (As the picture shows, the Run, Step, and Debug items are disabled -- both on the toolbar and inside the menus.)
This is true for all project types I've seen so far -- C#, Python, etc...
But mono-debugger is installed. Is there some post-setup task that I need to do manually, for this to work?
Looking over https://github.com/mono/monodevelop/blob/master/main/src/core/MonoDevelop.Ide/MonoDevelop.Ide.Commands/ProjectCommands.cs
Perhaps you haven't selected a 'Project'? Open up the Solution pad and click on the Test1 project (not the solution at the root of the tree, but the project just below it).
I'm just guessing here since I don't have Ubuntu and can't actually test anything.
Edit: actually, it looks like clicking on the Solution would work as well.
From looking at the code, another possibility is that you don't have a build target? Not sure how that would happen, but unless you only opened Main.cs and not actually Test1.sln, I don't know what to suggest.
When you opened the project, which file did you open? Test1.sln? Test1.csproj? Or Main.cs?
Try looking for mono-mdb and more packages in synaptic, this may fix this issue.
Don't remember exact names, Linux box at home...
Did you really open the project? It looks like you just opened Main.cs. It won't work that way.
Make sure you installed the compilers (mcs etc)
edit: The real solution to this is now that OpenCV supports python 3. I'm leaving the details below for anyone who happens to be stuck with an old setup.
I'm trying to get OpenCV working with Python 3. A friend showed me ctypes-opencv that appears to work with Python 3. The problem is I totally can not figure out how to "install" or get any code working. I've followed all instructions I could find from a few people mentioning installs on google and none of those seemed to work or I couldn't even get through the basics that they mentioned.
I am just hacking around with the version of IDLE that came with Python 3. No IDE.
Start with OpenCV:
The only windows installer for OpenCV 2.1 is a visual studio installer. I assume that means that it installs files that make it easier to use in Visual Studio. However, does it also mean that I can't use that installer with Python 3? I tried the vs installer together with ctypes-opencv as below, and I got errors that the dlls were not in my path (but my path variable did include the OpenCV bin folder with dlls). Is this the wrong direction?
The apparent alternative is to build OpenCV myself. I tried following the directions here and all I get is "project files may be invalid" from the CMake gui application when pressing the "Configure" button. Same when following these hints from Stack Overflow. I'm suspicious that this is also the wrong direction since I am not currently using any of the tools that are listed in the CMake configure. Is this also the wrong direction?
Next ctypes-opencv:
I installed this and the installer recognizes Python3.1 and puts itself into the site-packages folder. If I try to run demos, it tells me the dlls are not in the path although they are, as mentioned above.
Summary:
I think I generally understand each piece here (code, compile, dll, imports, ...) but I do not know how all the pieces fit together and where I am going wrong. Can someone please tell me what steps or understanding I am missing here?
I get the feeling that I need to be reading a book or two to fill in the holes in my understanding of how all these pieces fit together. I wouldn't even know what area of books to get though so any suggestions there would be appreciated as well.
Python's ctypes is a wrapper around the opencv dll files, as long as you can point to the compiled libraries it doesn't matter what the source code is set up to be edited in. For windows I would simply run the installer, then try to load the dll with ctypes. If you can get that far, any other errors can be fixed by looking at the ctypes wrapper file and editing the load section to look like your test file.
Christoph Gohlke maintains Windows binaries for many Python packages, including the production version of OpenCV 3.0 with Python 3.x bindings, released 4 June 2015:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv
To install, just download the 64-bit or 32-bit .whl file appropriate for your system, then run pip install [filename]. Then the instruction import cv2 should work in your Python 3.x interpreter.
Yakiimo san, OpenCV 2.1 DLL can be loaded with ctypes. I have tested it.
p.s. I have set the C;\OpenCV2.1\bin in Env Path.
