compiling

[InterFiction]

I'm trying to learn to compile projects into an exe file, but I'm having a hard time doing it. I'm not sure what to do. lol, even when programming console apps I never built an exe, I was just learning the language...but anyway

I was messing around in MinGW, and finally ended up with an exe file in my Debug folder for the project. When I tried to run it I got and error saying something like "mingWM10.dll" is missing..

I'm not sure about how to compile the project right..

any ideas?

The compilation went fine, but you have to ensure that the application can find its needed dlls. So have a look at the documentation on how to deploy a win application. It is very well described there.

Hey thanks. You wouldn't happen to have a link for the online documentation to the section I need? I've got a copy of the qt creator documentation here, but I don't know where to click in the documentation, or if I'm even looking at the right documentation for what you were talking about, lol.


this is the doc from QTcreator is that what you're talking about?

look here: http://doc.qt.nokia.com/latest/deployment.html and here: http://doc.qt.nokia.com/latest/deployment-windows.html

If you can't find anything in the documentation, google is your friend.

Hey, thanks for the links. I'll have a look through, and see what I can find. I've already tried Google, I find the links, and information a bit confusing..most of it aimed at people that know what they're doing, lol, that's why I posted here...I'm gonna read through the links though, thanks.

Hey, I'm trying to follow along with the second link. I've got MinGW open. it says to go to the dir of qt. I've done that. on this pc it's C:\QtSDK\QtCreator\bin\ . That's where the exe file for qt creator is. It says to type a configure command, and then nmake sub-src to configure, and build qt statically...

when ever I type these commands into MinGW it says they are not internal or external commands, operable programs, or batch files.. Something like that...

any ideas on how to fix this?

[Lykurg]

Ahh, first read, then go to action! You don't need to build Qt static! What you are looking for is at the bottom of the page. You successfully build your app. Fine, now you just have to deploy it alongside the right dlls. So make a new directory and copy the exe there.

Start the exe -> mingw.dll is missing
copy the mingw.dll to the directory
Start the exe -> QtCore.dll is missing
copy the QtCore.dll in the directory
...

ohh okay, I see what you're saying, haha, sorry about that. Just kinda excited to get it going. I'll read the links you gave a bit more, before I post again, thanks for the info.

I used that walker tool. It's telling me what I need, but I don't know where to find the files. Are they all stored in one location

Added after 15 minutes:

okay, I've got some of the dlls found in the bin directory coppied over into the root dir of my app, but there's two that aren't there. They aren't in the bin dir of qt..is there a safe place to find the ones that aren't on my computer? MINGWM10 is missing, and LIBGCC_S_DW2-1 is missing.

[ChrisW67]

Both of those files are on your computer. They are shipped with the MingW compiler suite, either in the Qt SDK bundle or a standalone MingW installation. Look in the mingw/bin folder.

[InterFiction]

Hey thanks for the info. That's where it was. You'll have to forgive me. I've never done this before. I searched through start and it didn't turn up nothing, look around in the folders a bit, but couldn't find it..it was there though, thanks.

Added after 7 minutes:

Hey, now that I've found them all, and understand how to find them, lol, I've got them into my project folder, and the app works. Thanks guys. That leads me to a new question. Is there a way to place these in another folder in my root so that the program still finds them. That way everything can be organized, or is this something that has to be done programatically?

[ChrisW67]

If you are using Qt Creator then these files should be found when you run the program from within the IDE - development does not require moving the files. If you want to run the program outside of the IDE during dev I would suggest you add the MingW bin and Qt bin directories to the system path rather than copying the files elsewhere on your system.

When you deploy the application you will have to place the files on the target computer using your installer of choice. I would recommend putting the two MingW/GCC and Qt library files in the same directory as your application and not in a system location.

You might also consider an external tool which is very simple to use, such as HM NIS Edit (http://hmne.sourceforge.net/). This is actually very nice because it generates an installation wizard that Windows users will be familiar with. You still have to know what and where the pertinent .dll files are on your system though, so this thread is still quite useful. Make sure that when you are ready to deploy you toggle from debug to release build targets in Qt Creator.

Setting up on the one hand and deploying on the other are to me the hardest things to settle into, so I appreciate threads like this. Thanks.
