So I am a total newbie (and you may have guessed because this is my first post/question here). I have a working OpenCV 2.4.8 install with Windows 8.1, running Visual Studio 2013 Express. I have downloaded OpenFrameworks for Windows ZIP archive and unzipped it. Now, I am stuck with the fact that I know nothing about what next to do. The setup guides on OpenFrameworks are how to install the IDE, not OF. The tutorials that are available are also more geared toward Macs, which I don't have access to for development purposes.
So, in short, I need some help in getting OpenFrameworks installed within Visual Studio 2013 EXPRESS, for my robotics high school robotics team, FRC.
By the way, has anyone successfully exploited the available resources from both, OpenCV and OpenFrameworks? If so, please let me know how I can get started integrating both together! ;)
So here's a little bit about me environment:
5 OSes (WIN8.1,WIN7, 250GB HDD, WIN7 32GB SSD, Ubuntu, under Wubi 30GB vDISK, Ubuntu, under Wubi 24GB vDISK), 6GB RAM, 1.5GB RAMDISK (can be disabled), i3-2367 (very slow) with CPU GOVERNOR PERFORMANCE under Ubuntu.
Thank you for your time and help, and peace!
if you would like to use with visual studio 2010, download the respective package from the below link.
http://openframeworks.cc/download/older.html
the latest version supports 2012 or above, which is 0.8 (I say, prefer the latest one, as it has good examples to start with)
After the installation, if you go to the respective directory of openframeworks, you will find a folder named project generator, use it to generate your project file. follow the below link to get an idea.
http://openframeworks.cc/tutorials/introduction/002_projectGenerator.html
As you are interested in opencv, you can use the addon available in openframworks ofxopencv and use couple of examples in examples folder to get used to its interface.

I am trying to embed Google's V8 in my game engine. I'm targeting 3 operating systems: Windows, Linux and OS X.
I haven't had any problems with building for Windows - I used NuGet packages. But I'm trying to build V8 for Linux and the problem is - I'm doing this on Windows (Windows 10 if it matters).
Google doesn't exactly say how to compile V8 for Linux using Windows and now I'm really confused, as I have no idea. So far I have depot_tools, properly fetched v8 (using fetch command), Python and MinGW.
I've tried with v8gen.py, but it seems that it generates build files only for Visual Studio. As I said, I don't need VS files.
My question is: What should I do?
This is not possible out-of-the-box with the current build tools and configurations that V8 provides. As suggested in the comments, using a VM might be the quickest way to get this working for you.
If it is very important for you long-term, or for other developers as well, you could look at submitting patches to V8 to make this possible, but I don't have a good sense of how much work that would be.
I've got a C++ VS2013 solution with 3 projects, using OpenCV 2.4.10, easylogging++ and Dlib libraries. The problem is that our client is now migrating to Linux (Ubuntu Server). I've looked into Cygwin and MinGW and a few questions here on stackoverflow, but I'm still lost as to where I should start. I need this done as soon as possible, so the simpler solution would be best. I really appreciate any help you can provide.
I recommend using cmake build system on ubuntu. Using Opencv and easylogging on ubuntu out of the box could be a matter of minutes. dlib's website also mentions a simple cmake building steps that works on ubuntu.
After you get your libraries up and running, build your code and see if there are any system-dependent functions then google how to standardize them across systems. If your code is already standardized it should run right then and there.
You can then ask about any specific issues you meet on the way.
For a long time opencv has been (and still is,) the main infrastructure for 2d development.
When going 3d, PCL is the natural choise: it has vast range of algorithms implemented, online API documentation, and the backbone of the industry's leading companies.
That said, How can it be that the last binary is for IDE 5 years ago?(!!!) last update was in 2013 (probably due to the death of OPENNI, thank you Apple), the implementation is obsolete , and I am not even talking about c++1x, nevertheless the futuristic compute capability 5.x.
Is PCL a dead project? are there's any predecessors?
I too work with PCL and find the outdated libraries frustrating. However as PhilLab mentioned the GitHub page is still active.
HOWEVER: Thanks to Tsuksa Sugiura there exists a perfect pre-built package for Windows + VS2015. He even maintains this and updates it. Both x86 and x64.
ALSO it is possible to use 1.8.0 RC2 on the NVidia Tegra platforms, such as the Jetson TX1. here the CMake system is working relatively well.
AND ROS supports it (again defaults to 1.7.2, but can run on 1.8.x)
So to conclude; sure no one is packing it into tidy releases, but the package is slowly getting advanced. And it kind of is our only choice...
Also to the moderators: I would have commented this on PhilLab's answer as I feel this doesn't dignify a new answer... but on this strange community you can answer before being able to comment. Sorry.
I share your frustration with the outdated prebuilts (outdated both in IDE version and PCL version) but the project is still quite active on GitHub: https://github.com/PointCloudLibrary/pcl/commits/master.
The release cycle seems to be quite lengthy but the commits come in steadily
Edit: Release 1.8.0 is in preparation and the lack of Windows builds is because the lack of a Windows programmer
Edit (06/2018): The newest versions include windows prebuilds
Now the best option to use PCL on windows is using the vcpkg package management system to manage the dependencies and binaries.
Is there anyway I can do USB programming in Qt? I am using Qt Creator 2.6 which is based on Qt version 5.0.0 and it is the latest Qt Creator which works with the Microsoft Visual Studio 2010 compiler.
I have the toy called "Dreamcheeky Thunder Missile Launcher" and I need to program this USB based device.
I have tried LibUSB but it messed up everything. It even renamed the device port and I had to undo everything using USBDview software. But I guess I installed it incorrectly. I followed these instructions. It is instructions for 64 bit, but I got 32 bit and since the instructions seems not to have big difference (instead the download file) I followed it. This is what I downloaded - libusb-win32-bin-1.2.6.0.zip
Whatever the API you recommend it doesn't matter, even libusb, but please be kind enough to tell me how to install it properly.
My OS is windows 7 ultimate 32 bit.
ollo's answer is out of date. TL;DR is use libusb.info. A bit of explanation:
Originally there was libusb-0.1. Later they updated the API to libusb-1.0, but since libusb-0.1 had been around so long many projects didn't bother switching (kind of like Python 2/3). libusb-0.1 was not available for Windows, but libusb-1.0 is now available for all major platforms.
libusb-win32 is a port of libusb-0.1 to Windows. You shouldn't use it for new code.
libusb.org is the old website for libusb. The latest release is from 2012 and there are no Windows downloads.
libusb.info is the current website for libusb. It contains libusb-1.0 downloads for all platforms and you should use this for new code.
To further confuse things, the sourceforge libusb-win32 mailing list is still used for libusb.info's development.
There's another good instruction for libusb here: http://www.dreamincode.net/forums/topic/148707-introduction-to-using-libusb-10/
libusb:
libusb
libusb-win32 (windows port - use this on windows!)
If you stay on windows you can use
WinUSB:
WinUSB API
Example
Installation
For windows you can use both, but if your program has to be cross-platform you should use libusb.
How do Window's programmers profile their native C++ code?
On Unix/Linux you have gprof [thanks Evan] & valgrind (I personally used this one, although it's not a real profiler), and recently I'm on Mac and Solaris, which means I moved to dTrace. Now when I've had the need to profile on Windows in the past, like at my previous job, I used Intel's vtune, which is great, however it's commercial, and I don't have a license for private use, so I'm left wondering what's the standard (free is better) tool windows programmers commonly use?
Thanks in advance
You should give Xperf a try - it's a new system wide performance tool that can drill down to a particular application and what exactly it's doing inside itself as well as what's it's asking of the OS.
It's freely available on the Windows SDK for Windows Server 2008 and .NET Framework 3.5 ISO:
Install the SDK by downloading the ISO image, or using the Web based
installer.
Find the xperf MSI in the SDK's "bin" directory. It will be named
xperf_x86.msi, xperf_x64.msi, or
xperf_ia64.msi, depending on the
architecture for which you install the
SDK.
You can then install the xperf tools from the MSI directly, or copy
the xperf MSI file to another location
and install it from there. For
example, you could keep the MSI files
on a USB key.

Just verified that the xperf msi will not install except on windows Vista or Windows 2007.

I got AMD Code Analyst. It's free, and you don't need an AMD CPU ;)
It's a little basic compared to something like Intel's VTune, but the price is right.
This link talks about Linux, but I use the same technique in MSVC and in C#.
