I'm trying to build multi-file project. How do I use ino build in a way that doesn't give me a bunch of not declared in this scope error when using multiple files like Arduino IDE?
If you are already working on the command line you might want to learn about the C++ build process.
Then start to learn about SCONS. Once you understand this you do not want to mess with Arduino IDE + INO files anymore. A suitable sconstruct can be found here.

I would like to know if it is possible to use selective arduino libraries in our AVR projects. For Example: I am using Atmega328 and Atmel studio. I would like to use DS1307 related library file(twi.c and Wire.c source files I guess) in my project. Can we use individual libraries and then include applicable header files in our build? If so where are these libraries located and what is the extension? I saw few articles on building entire arduino project in Atmel studio and I am not interested in that. I want to manage without installing arduino if possible (I can install arduino only to get library if needed). I thought of including source files, but they are in C++ and I started getting error messages when included in C project. Is it possible to do without modifying the source files much?
After searching, i found that
Any 5V microcontroller with I2C built-in can easily use the DS1307.
check also first lines here.
I look quickly at DS1307.c and found it is not using any functions from wire.c
But instead of all that you could get source code for DS1307.c and implement any function begin with i2c by yourself and small modifications for interrupt functions. and you can use it in your code. i downloaded the library from this link.
There are a lot of twi/i2c libraries for avr, you could download most suitable one and rename it's function like the function called from DS1307.c
I'm trying to write my first Qt installer and having trouble. In my installer, in one of the packages, I need to run an .exe file at the end of the installation and add an environment variable as well.
I think the way to do it is with the script option in the package.xml file but I don't know how to write that script, I cannot find a step by step explanation of how to do it anywhere.
Can someone help?
I have been recently suffering the same fate as yourself but have managed, for the most part, to achieve what you are trying to do from the Qt installer framework examples and documentation found here http://qt-project.org/doc/qtinstallerframework-1.5/index.html and http://doc.qt.io/qtinstallerframework/qtifwexamples.html.
The information provided on these pages is a little ambiguous but with a little experimentation you should be able to create the install script that you require.
The package.xml file you would like to implement the install script requires that you add a
<Script>installscript.qs</Script>
tag and that the installscript.qs its self should be located in the meta folder of that package. The installscript.qs will then contain, among a few other things, a
component.addOperation("Execute".....)
command which will execute your required .exe. The same process for the environment variable could be implemented using the execute operation to run a batch file which creates the variable on the users system.
I have been trying over the last few weeks to implement the custom operations detailed in the qt installer framework documentation but have so far been unsuccessful so if you make any progress in this area feel free to pass the information on ;)
Guys I've written app in qt and when trying to run it (double click on *.exe) I'm getting error that this application cannot start because qtnetwork4.dll isn't available. I've searched my drive and I found few files with this name (and copied one by one every time trying to run my app) but none of them seems to work. How can I solve it?
place into your *.exe - folder appropriate dll-s from %QT_PATH%\bin\
There is an app called Dependency Walker that will let you know what functions in qtnetwork4.dll are being used in your program. It can be found at the following:
http://www.dependencywalker.com/
All of the DLLs your program use will be from the same installation as the qmake.exe that is used to compile the program. If you are using Qt Creator you can see where the qmake.exe your using is located by going to:
tools->options->Qt4
Get the DLLs that are located at the path displayed here to make sure they will work with your program.
On windows, DLL are looked for in folder where executable lies, then using "PATH" environenment variable.
In your case, you want to put your dll along your executable, taking them from the sdk you're using to compile
The following page provides a lot of additional information on the subject (example, plugins, strategy for building installers)
To force using QtNetwork and linking it, you have to put
QT += network
in your poject file.
If you're sure you're not using it, you can use
QT -= network
I'd like to offer my .Net library (which I'm developing in the SharpDevelop IDE) as a single dll. I've been manually using ILMerge to merge my compiled library and all its reference libraries together, but would like this done automatically.
I'd ideally like to have this automatic merge happen from within SharpDevelop, without having to set up an external build script. Is this possible?
SharpDevelop uses MSBuild to compile your code so the simplest way would be to create a post build step that runs ILMerge with the correct parameters. You can create a post build step from the Project Options under the Build Events tab. Alternatively you can directly edit your project file in Notepad.
I am new to Netbeans. I am wondering if someone can help me with project setup in netbeans. I am moving half million lines of Java code from a different IDE to Netbeans. I was able to get the code build and run in Netbeans easily. I have a project with many folders with dependencies among those folders. They have to be built in specific order. This is to enforce layering so that a module in lower layer cannot call into higher layers. I couldn't get that configured in Netbeans. Below is how my project looks like
project/
libA/
libB/
libC/
libD/
libE/
appA/
...
I have one project that builds all the libs and appA. The project build xml is stored under project/ folder. But the libs have dependencies among them. libB should be built after libA. libC after libA. libE depends on libD and libB etc.
I tried to change the order of source folders for libs in project properties. That didn't seem to make any difference. Even if I move libA after libB, it was building everything fine. I expected it to fail because libA didn't build yet.
Iam lost. Just wondering what the trick is to enforce this kind of dependencies. I created my project using "Java project using existing sources" wizard.
I appreciate your help
Thanks

Even though it would be a pain, you could just write your own ant build script and then just have Netbeans use that.
Basically:
write the custom ant build file
install the Ant plugin
create an Ant build file
right click the build file
run the selected target.
This would enable you to enforce whatever you need to do, but, if Netbeans is figuring out the correct order then why not just use it.
Does something break when you just compile and run in Netbeans?
Well! Lets say a team member added piece of code in lower level package that calls into higher layer code. It should fail because it breaks the layering. Because Netbeans seem to compile all the files in one javac invocation, the build compiles just fine. I want Netbeans to break the build in this case.
Writing my own ant script is another way of enforcing it. The whole point in using an IDE is to save yourself from writing your own make files (or ant scripts). This is something any IDE was able to accomplish 10 years back out of the box. I am wondering if I am missing something here.
