I have bought, downloaded and then installed uFlex for Unity. The install seemed to go without any errors, but when I try to run any of the example scenes I get lots of errors. The first and most serious sounding of which is:
DllNotFoundException: flexRelease_x64
uFlex.FlexSolver.Start () (at Assets/uFlex/Scripts/Solver/FlexSolver.cs:102)
Also the scenes don't seem to run/work. Have tried googling to see if it's a common error but that didn't show up anything. Tried finding the missing DLL but not sure where to put it, or whether it's platform/version specific?
Any thoughts on how to troubleshoot this
Anyone else have similar issues?
Not sure if it's relevant but I'm running Unity Version 2017.2.ob11 Personal, and my OS is Ubuntu 16.04.5 LTS. I have windows installed as well - is switching to running Unity under Windows likely to help?
It won't and shouldn't work on Linux at this point.
Read the requirement from the plugin page:
NVidia GPU with at least CUDA 3.0 compute capability
Windows 64 bit (Win 32bit experimental, Android and Linux support planned)
The support is currently for Windows. You get the exception because the dll for Linux has not been provided. It can't load Windows dll on Linux. If the native side (C++) of the plugin is open-source, you can compile it for Linux and include it in your project then it should work. Since it's not, your only option at this moment is to switch to Windows.
I'm using Ubuntu 14.04 (64 bit). After installing leJOS_NXJ_0.9.1beta-3, I was able to flash the NXT device. However, when I tried to upload a program, it showed a message "Found NXT: NXT 0016530CDF15" and then just stuck there.
I also tried Eclipse with leJOS plugin, and got the same problem. It showed
Program has been linked successfully
Uploading ...
Found NXT: NXT 0016530CDF15
and it got stucked there.
Can anybody help me with this issue?
Thanks,

This site might be able to help, it provides the information to install and configure correctly all the software necessary for you to develop Java programs for the NXT, maybe by following this site it will hopefully fix the problem.
This tutorial will show you how to install and configure all the software necessary for you to develop Java programs for the LEGO Mindstorms NXT. Java is much more powerful and flexible than the original NXT-G software that LEGO provides. We will be using the Eclipse editor to write the actual Java code and to download this into the NXT. This combination enables you to conveniently write software and to quickly test it on the NXT. Of course there are many other Java editors, but we consider this combination to be particularly convenient. This tutorial focuses on the Windows XP platform, A Mac OS X tutorial is also available. We have two additional steps for Windows Vista. You will work through the following five steps - See more at: http://www.bartneck.de/2008/03/04/java-lego-nxt-eclipse-tutorial/#sthash.h1ZOZvlX.dpuf
What's missing in dbgeng.dll in windows 7 Vs the dbgeng.dll distributed with debugging tools for windows ?
Very late to the party on this one but I've run into one very significant difference recently:
The dbgeng.dll built into windows installations will not support remote debugging where as the one installed with debugging tools does!
There appear to be other differences also that I didn't dig deeper into - all I knew was a working program using the built in dll started crashing when using the debugging tools one... which was a pain considering I would have liked to use the remote debugging facility out of the box.
This post shows the difference between Windows 7 and Windows 8 preview, I believe Windows 8 version is similar or possibly same as latest one that ships that is in debugging tools because when I do use dependencyWalker I notice that the one in Debugging Tools also has this new exported method DebugCreateEx which is also in the latest version
Windows 7 System 32 version:
Dependency walker:
Debugging tools version:

Hope this helps in some way to explain the differences, especially the post at the top.
Situation: I've already written an ActiveX control for my IE users which works perfectly. I build the .ocx, CAB it up, sign it, and put it on the site with an EMBED tag. Users load the page, the yellow bar shows up asking if they want to install it: all they have to do is click it, and we're off.
Now I need to build support for FF, Chrome, and Safari (on Mac). From my research, NPAPI is the way to do this, and Firebreath is supposed to make it easier. But from what I have read, deployment is not so easy. Windows users would have to run "regsvr32" on a DLL (which none of my web users would actually do). I have no idea what would happen on a Mac. I believe the user has to copy it to a directory like /Library/Internet\ Plugins/, which is also a non-starter for deployment. Firefox users would download/run an .xpi. Chrome is supposed to run a .crx.
Does anyone out there have experience with this? How do you do a easy-for-users-to-run deployment of an NPAPI plugin for the other big 3 browsers?
This is a question that is raised a lot by FireBreath users, so it's probably about time I responded in more detail on a forum that is easier to find than the project google group.
First of all, to clear up the regsvr32 thing, FireBreath does indeed support "self registering" for all browsers; that means when you call regsvr32 it installs registry keys not just for IE but also for NPAPI browsers using the methods linked to by DReJ (+1 for that info, btw, thanks. Many don't know where to find it).
However, self-registering DLLs is highly discouraged in the installer world and by Microsoft. There are a lot of reasons for this. You've done a pretty good job of summarizing the other install options in your post; You can use a .cab on IE and a .XPI on firefox, but of course those don't help you on other browsers.
The method recommended by the FireBreath team (which I lead) is to use an MSI installer for all browsers. Personally, I dislike having things work differently on different browsers for an install, so I use javascript to detect the presence (or absence) of the plugin and then prompt the user to download and run the MSI installer.
FireBreath has "built-in" support for building MSI installers with WiX. If you install WiX 3.0 or later on your machine and re-run the prep script it will create a _WiXInstaller project that will build a basic MSI to install your plugin for all browsers as part of the Visual Studio build process. You can modify the .wxs template that will be left in your home directory to customize it.
More info can be found on the FireBreath wiki:
http://www.firebreath.org/display/documentation/WiX+Installer+Help
http://www.firebreath.org/display/~me#iaincollins.com/Potential+Installer+Improvements
If you are really in love with using your .cab installer for IE (I've had problems with them, but some seem to have good luck with them) you can distribute the MSI file inside your CAB and have it run when the CAB is installed. The advantage to this is that when you install the MSI it installs everything for IE, Firefox, Safari, Chrome, and Opera (as well as other browsers which are compatible with the same plugin technologies that those browsers use).
As a quick note, the reason that an MSI is the ideal solution for installing plugins (as opposed to using something that calls DllRegisterServer like regsvr32) is that the MSI is transaction based, so when you uninstall it will always reverse what was put in; that means that you don't have to worry about supporting uninstalling 10 different old installer versions that put things in different places, etc, because the MSI system takes care of uninstalling everything cleanly when you upgrade.
Hope that helps!
For NPAPI plugin you shouldn't run "regsvr32", in Windows you need to write some stuff to the register and on Mac or Linux you need to copy the plugin to specified locations (see "Installing Plug-ins"). I think the easiest way to deploy NPAPI plugin on Windows is to create windows installer that will install both activeX and NPAPI versions of the plugin (for example, you can look how deployment is done for commercial plugins like Unity3D, Roozz or Silverlight). The same is for Mac - just create installer.
I'm not aware of any way to install a plugin from within Safari.
Also, keep in mind that while you may think of the extension-style deployment as easier for users, it's not all that uncommon for Mac users to use more than one browser. If you make them re-install your plugin in each browser they will be confused (since that's not how browser plugins are generally deployed on the Mac) and annoyed. An installer or a manual drag-and-drop installation are the standard ways of deploying plugins on the Mac.
Does anyone know of a good software development framework or similar that has the following properties?
Cross platform: it should be runnable on XP, Vista, OSX and common versions of Linux (such as Ubuntu and Kubuntu).
No installation: Be able to run the software from a USB stick without having to copy anything to the host machine.
Have good GUI support (this is why this question doesn't give a suitable answer, as far as I can tell).
Permissive licensing such as LGPL or BSD or such.
Among the softer requirements are having a set of abstractions for the most common backend functionality, such as sockets, file IO, and so on (There is usually some platform specific adaptations necessary), and supporting a good language such as Python or C++, though it is usually fun to learn a new one (i.e. not perl).
I think possible candidates are Qt 4.5 or above (but IFAIK Qt software will not run on Vista without any installation(?)), some wxWidgets or maybe wxPython solution, perhaps gtkmm. The examples I have found have failed on one or another of the requirements. This does not mean that no such examples exist, it just means that I have not found any. So I was wondering if anyone out there know of any existing solutions to this?
Some clarifications;
By "framework" I mean something like Qt or gtkmm or python with a widget package.
This is about being able to run the finished product on multiple platforms, from a stick, without installation, it is not about having a portable development environment.
It is not a boot stick.
It is ok to have to build the software specifically for the different targets, if necessary.
The use case I am seeing is that you have some software that you rely on (such as project planning, administration of information, analysis tools or similar) that:
does not rely on having an internet connection being available.
is run on different host machines where it is not really ok to install anything.
is moved by a user via a physical medium (such as a USB stick).
is run on different operating systems, such as Windows, Vista, Ubuntu, OSX.
works on the same data on these different hosts (the data can be stored on the host or on the stick).
is not really restricted in how big the bundled framework is (unless it is several gigabytes, which is not really realistic).
It is also ok to have parallel installations on the stick as long as the software behaves the same and can work on the same data when run on the different targets.
A different view on the use case would be that I have five newly installed machines with Vista, XP, OSX, Ubuntu and Kubuntu respectively in front of me. I would like to, without having to install anything new on the machines, be able to run the same software from a single USB stick (meeting the above GUI requirements and so on) on each of these five machines (though, if necessary from different bundles on the stick).
Is this possible?
Edit:
I have experimented a little with a Qt app that uses some widgets and a sqlite database. It was easy to get it to work on an ubuntu dist and on osx. For windows xp and vista I had to copy QtCored4.dll, QtGuid4.dll, QtSqld4.dll and mingwm10.dll to distribution directory (this was debug code) and I copied the qsqlited4.dll to a folder named "sqldrivers" in the distribution directory.
You mention wxWidgets but dismiss it as failing at least one of the requirements.
I don't know what your requirements are and in what way wxWidgets wouldn't work for you, but IMO it does fulfill them:
Cross platform: it should be runnable on XP, Vista, OSX and common versions of Linux.
It does run on those platforms, but "common versions of Linux" isn't good enough, as you can never be sure that the necessary GUI libraries for wxGTK (which should not be linked to statically) will be installed. This is however a problem for other solutions as well, unless you plan to put everything onto the stick.
No installation: Be able to run the software from a USB stick without having to copy anything to the host machine.
See the previous point, you would need to specify which libraries are needed on Linux. Also you could specify at build time not to use some of the system-provided libraries (for example for graphics, compression, regexes) but to use the wxWidgets-internal libraries instead.
Have good GUI support
Check.
Permissive licensing such as LGPL or BSD or such.
Check. You can statically link wxWidgets into your application too.
supporting a good language such as Python or C++
Supports both, and there are bindings to other languages as well.
having a set of abstractions for the most common backend functionality, such as sockets, file IO, and so on
It does have some abstractions like that, but you can link to other cross-platform libraries as well.
We use wxWidgets for FlameRobin, a graphical administration program for the Firebird SQL server. It has active ports to Windows, Linux and Mac OS X, and has been compiled for at least some BSD variant and Solaris as well. It definitely runs from a stick on Windows, I haven't tried with Linux or Mac OS X, but I don't see why it shouldn't there too.
Java.
It has GUI support.
It provides your network/file/etc. abstractions.
It is cross-platform. Most platforms you can think of have a JRE available.
No need to install a JRE. Most users probably already have one, and if not, you can run the appropriate JRE right off the stick.
You can provide several startup scripts for various platforms to run the app under the appropriate JRE.
Something else to consider is HTML+Javascript. :D
You can look at Mono it cross platform, has GUI (GTK+, or Winforms 2.0) and I can execute code without installing.
This might not be crossplatform, but is maybe even better, it dont even use the platform : linux on a stick :-)

Well, it depends on what you mean by 'package'. Kylix came close to being such a thing. It was QT based, and it allowed you to write once and compile for Windows + Linux. However, it was not an open source solution.
I asked a similar question in this link
http://www.24hsoftware.com/DevelopersForum/CrossPlatform-C-Library.html
and the best asnswer seems to be QT.
I have started using QT, but it is not as easy as I expected mainly due to deployment problems due to the DLL hell, Winsxs hell and manifest hell.
Tclkit is a single-file, self-contained Tcl/Tk system. The mac version I have is about 3.8 megs. You can get a version for just about any modern OS. I carry around a thumb drive that has mac, windows and linux binaries so I can run my scripts on any platform. No install is required, just copy one file wherever you want.
The most recent versions of tcklit use native, themed widgets (though, on *nix there really isn't a single "native" set of widgets...)
