I've been struggling to get my application deployed properly for several weeks now (it's a hobby), and I just don't know what else to try.
I started a new project in Qt Creator (2.6.1), by selecting Applications -> Qt Quick 2 Application (Built-in Elements). I tweaked the QML to make the background blue and text red:
main.qml
import QtQuick 2.0
Rectangle {
width: 360
height: 360
color: "blue" // Added!
Text {
text: qsTr("Hello World")
anchors.centerIn: parent
color: "red" // Added!
}
MouseArea {
anchors.fill: parent
onClicked: {
Qt.quit();
}
}
}
I'm using Qt 5.0.1 and the x86 MSVC 2010 compiler. I built the Release version and it ran fine in QtCreator. If you need more compiler specifics, I'll post them.
To deploy, I created a new folder on my desktop called HelloWorld/ and copied everything from H:\Qt\Qt5.0.1\5.0.1\msvc2010\bin\* and H:\Qt\Qt5.0.1\5.0.1\msvc2010\plugins\* and 'H:\Qt\Qt5.0.1\5.0.1\msvc2010\qml* into it, along with the Release HelloWorld.exe executable.
Overkill? Yes. But I'm desperate.
When I run HelloWorld/HelloWorld.exe in Windows 7 64-bit, the application runs fine. But when I copy this HelloWorld/ folder over into a virtual machine running Windows XP 32-bit, it shows a properly-sized window, but with nothing in it (white, with no text). When clicking in the center of the window, the window closes as it should.
So I loaded the executable in Dependency Walker, but nothing looked out of the ordinary (IESHIMS.DLL and WER.DLL were of course missing). I ran Start Profile, and got a slew of red errors:

I also tried to run a debug version, but I only have the 64-bit versions of the MSVC100 dll's, so I can't copy them to the XP machine (I can only run the 32-bit redistributable). I don't know what other tools I can use to try to solve my problem.
I know I must be doing something stupid, but I really can't find anything on the internet to help. It's really frustrating to spend so much time developing a Qt application, and then get stuck trying to deploy it.
I should note that the program runs just fine in a Windows 7 32-bit virtual machine (after MSVC2012 redistributable has been installed).
The application I'm really interested in running, runs really strangely in Windows XP. When I first run it, the window sizes properly and a couple text strings show up. But none of the Rectangle{} elements are displayed. I left the app running for a few minutes as I made myself some coffee, and when I returned to my computer, the window was blinking random shapes and text, to the beat of the text cursor! What the heck is that?! It looked like a basic math function was screwed up, so parts of the interface were being displayed at improper sizes and positions. I even saw the real interface show up for one blink of the mouse cursor (and yes, the random shapes appear and disappear to the beat of the mouse cursor).
On a whim, I tried using the application (clicking where I know a text box exists), to populate one of the lists, and it worked! The application is running completely fine, except for the graphics. I know Qt 5.0 reworked some of the OpenGL handling, right? Could this be a bug, or maybe a library I haven't installed?
I also encountered the same problem when deploying quick 2.0 application on Windows XP builded by Qt 5.1 rc1 with ANGLE; It's seems to be ANGLE problem, on http://qt-project.org/wiki/Qt-5-on-Windows-ANGLE-and-OpenGL is recommended to use OPENGL for XP, also Qt 5.1 with OPENGL works for me on Windows XP
Install Microsoft Visual C++ 2010 Redistributable Package (x86)
on client machine (windows xp).
Use release build, not debug build, You seems to be using Debug
version.
Don't use OpenGL(Most of XP Users may note have updated OpenGL
version, otherwise you may have to force them to upgrade it.)
Update
Use OpenGL for Windows XP. User have to install or upgrade their OpenGL drivers. Read this.
Try using the MinGW version instead of the VC++ one. It's likely that there are layers and layers of .Net stuff preventing you from running on XP. XP came out before 90% of the current .Net stuff existed which is why it wont work as it's not installed.
Just a guess but its worth a shot.

I'm working on a VC++ app, and my job is to correct some bugs in it, the code was mainly written by a student last year.
It is a graphical application that uses both SFML and TGUI.
It targets 32bits architectures but actually its only working well on x64 computers.
On a x64 , absolutly everything works perfectly , but on a 32-bits systems , the text displayed using sf:Text and sf:Font just prints black blocks after the first call to the function that sets sf:Text's string.
I know that code targeting 32bits systems should work fine on x64 , and that's why I am lost. I checked which system architecture I am targeting.
I am using compatibles , 32bits , last updated SFML and TGUi libraries.
I checked a billion times if I got the right dlls, include and lib paths . The linker > start property got all .lib that both sfml and tgui relies on.
I know that the Font is loaded, but I know that it doesn't stay set on the Text even if the variable containing the font isn't destroyed and that I have set the font on the text earlier.
This is how the font is loaded and associated with the text :
MainWindow.cpp :
Font& MainWindow::m_fontDisplayer = m_data.getFont_1();
//init displayer
m_data.getDisplayer().setFont(m_fontDisplayer);
m_data.setDisplayer("");
m_data.getDisplayer().setCharacterSize(54);
m_data.getDisplayer().setFillColor(Color(0, 0, 0, 255));
DataManager(m_data):
Font DataManager::m_font_1 = Font();
if (!m_font_1.loadFromFile("Ressources/font_1.ttf"))
{
printf("\nCould not find font_1.ttf font.");
}
void DataManager::setDisplayer(std::string s) {
if (m_displayer.getFont() == NULL) {
//m_displayer.setFont(m_font_1);
}
m_displayer.setString(s);
m_displayer.setPosition(sf::Vector2f(320 - m_displayer.getGlobalBounds().width,82));}
This function is the one that maked me say that the font isn't set to the Text after some time.(m_displayer is sf::Text)Because I have set a stop point at the commented line and that it is accessed even if setting the font is the first thing that i do. Actually , that "if" statement was only to check the stop point, It doesn't fix the problem (makes my app crash on 32bit), and it would be too long because sf:Font operations are really heavy.
What could possibly cause that compatibility issue between the two architectures?
To add to what i said , I'm sure that the only difference between the systems im testing on is the architecture and not windows version. I tried on multiple computers, and again , the problems only appaers on 32-bit computers.
Thanks to anyone that could explain and help me understand the problem.
EDIT : I cleared the text about Tgui issues as i solved them.
So I am a newbie to OpenModelica. I have a bit of experience using LMS Amesim. I created my first simple model using OM and simulated it from within the OMeditor.
When I switch to the plot window, there are NO output variables to plot. That tells me that the simulation may not have run. However, no error messages popped up. When I checked the model, I found it to be fine (not overconstrained or underconstrained).
What gives? This is OM 1.14 on Linux Ubuntu 16.04.
My Modelica file is a simple 2nd order system with feedback control is available via pastebin here or may be downloaded here via google drive link
The messages that I have from the output window are:
/tmp/OpenModelica_drN/OMEdit/Feedback/Feedback -port=35318 -logFormat=xmltcp -override=startTime=0,stopTime=100,stepSize=0.2,tolerance=1e-6,solver=dassl,outputFormat=csv,variableFilter=.* -r=/tmp/OpenModelica_drN/OMEdit/Feedback/Feedback_res.csv -w -lv=LOG_STATS -inputPath=/tmp/OpenModelica_drN/OMEdit/Feedback -outputPath=/tmp/OpenModelica_drN/OMEdit/Feedback
The initialization finished successfully without homotopy method.
The simulation finished successfully.
This was a bug. Should be fixed now:

I am using the following library to connect via USB to an external device:
https://github.com/node-serialport/node-serialport
I set up the following sample project to narrow down where the issue might be:
https://github.com/nyoung697/node-serial-test
This code works on my Mac. The device I am connecting to accepts an ascii command and the carriage return to terminate that command.
In the example project, I am passing in 'V\r' and am expecting the version of the device to be returned. When I run this code on my Mac, I get the expected response.
However, when I run it on my Windows 10 machine, I do not get any response at all. Neither the port.on('data') or port.on('error') events are hit.
I tested downgrading the serialport library to version 4.0.7 and it does work.
Does anyone have any ideas what might have changed between 4 => 6?
P.S. I edited this question, as I originally thought it had something to do with Electron, however after doing this simple test with only node.js, I believe I have narrowed it down to this version of the library on Windows.
Okay... I just figured this out.
All I needed to do was add the property 'rtscts' to the openOptions object I pass in to the constructor and set it to true.
const SERIAL_PORT_SETTINGS = {
baudRate: 115200,
rtscts: true
};
let port = new SerialPort(devicePath, SERIAL_PORT_SETTINGS);
I figured this out by digging around in the release notes. I noticed that from v5.x.x to 6.0.0 the breaking changes included making this value default to false.
windows: We previously hard coded to have RTS on for windows at all times it now default to off.
This looks like a bug in either NSProgressIndicator or Xcode 9 to me:
Run Xcode 9 Beta 1 or Beta 4, in macOS 10.12.6.
File > New Project, macOS, Cocoa app, Objective-C or Swift, ARC or not, no storyboards, latest (10.13) SDK.
In the app target's environment, set CA_ASSERT_MAIN_THREAD_TRANSACTIONS=1.
In app delegate, add a IBOutlet progressIndicator.
In the nib, add a NSProgressIndicator to the window, connect to that outlet. Leave the checkbox Indeterminate switched on.
In -applicationDidFinishLaunching, call -startAnimation: on progressIndicator.
Build and run.
Expected Result:
Progress indicator should happily show indeterminate progress, because I did everything on the main thread.
Actual Result:
App crashes, citing CA_ASSERT_MAIN_THREAD_TRANSACTIONS, when
-startAnimation: is called.
You can see this in a tiny demo project.
Did I do anything wrong? Is my Expected Result incorrect?
P.S. I asked this on Apple's Developer Forums, but still awaiting moderator approval after 2 working days, so I deleted it and came here instead :(
Update: Still lacking an explanation, I filed Apple Bug 33593575.
This was a bug in NSProgressIndicator. Your bug report (thank you for filing!) was marked as a duplicate of an earlier bug, which was already resolved in macOS 10.13.
I've been trying for hours, but can't build and use Light Table. Every time I try to run deploy/LightTable, it hangs on a screen that simply says "Light Table". I receive this error*:
[14381:0519/204037:INFO:CONSOLE(27860)] "Uncaught TypeError: Cannot read property 'thread_STAR_' of undefined", source: file:///home/zaz/Desktop/LightTable/builds/lighttable-0.8.0-linux/resources/app/core/node_modules/lighttable/bootstrap.js (27860)
Here's what I've tried:
git clone https://github.com/LightTable/LightTable.git
cd LightTable
bash linux_deps.sh
./deploy/LightTable # creates frozen window, throws the error above
cd deploy
./LightTable # creates frozen window, throws the error above
./ltbin # creates frozen window, throws the error above
I also tried similar things after checking out the atom-shell branch and the 0.7.2 tag (and cleaning up all the files from the previous build). Each time, I received the error above.
Does anyone know what's going on here?
Has Light Table been completely abandoned? It seems the last commit was in March.
* Depending on the version I was trying to run, I also received other errors, but I don't think they're relevant (the error above was the only one that appeared for all versions):
[18593:0519/222845:INFO:gpu_info_collector_x11.cc(80)] NVCtrl extension does not exist.

A year later (question was written in May 2015, now is June 2016), LightTable 0.8.1 is out, and I tried both Linux binary and cloned it from git, and it works fine.
For complete info, I'm using also Atom, and although I had not problems with "Cannot read property 'something' of undefined"" in Atom core, I met such problems in two or three Atom packages.
Both editors are based on same electron platform, LightTable is beautiful eye candy with quite revolutionary REPL integration, but it needs more polish to be usable to same extent as Atom.
For example, LightTable does not have workspace saving by default, that is done via plugin. That's ridiculous.
But although Atom looks so nice and powerful compared to simple editors, with realy huuuge number of available packages/plugins, LightTable is more elegant.
As I don't want to start new semi-religious war Atom vs LightTable resembling vi-vs-emacs, I'll stop here. :)
I can't replicate your problems in LightTable v0.8.1, so I think that answers this question. If not, please add errors you get with v0.8.1.
