I would like to create an executable file of my project. I've looked at several tutorials to do this but all the ones I'm looking at do it on the same package. The problem is that my project has many packages and I can't create the executable.
I tried to do in shell in the root folder of my project : javac *.java but it does not work
So I tried to do the same command but in one of the package where some of my classes are. This time I have this error : App.java:3: error: package javafx.application (its an import for my project) does not exist
However, I have the impression to make the right command.
if you want to see what I have
My project :
to the root project has one of the packages with 2 classes
this 2 classes
so in shell I do :
my commande from the package
my error
my commande from the root project and my error
thank you in advance if you can help me a little and thank you for taking the time.

I downloaded the source for AdaControl from the SourceForge Repo. Using GNAT 2017 CE, I get the following error on make:
$ make build
gprbuild build.gpr adactl -cargs -bargs -largs
build.gpr:1:06: unknown project file: "asis"
gprbuild: "build.gpr" processing failed
make: *** [adactl] Error 4
The instructions make it sound like this is all I need to do, and offer no troubleshooting suggestions:
Go to the root directory of the distribution and type:
make build make install
As this related question notes, I have managed to get ASIS to build, though it also comes packaged with GNAT 2017 CE.
That message means that ASIS4GNAT isn't installed in a place where gprbuild (and the rest of your GCC/Ada tool-chain) can find it.
You can use the command gnatls -v to get an idea about where your GCC/Ada tool-chain expects project files to be located.
Compare that to where you actually installed ASIS4GNAT, and you may be closer to a solution.
I'm currently an undergraduate researcher and I've been tasked with researching knowledge defined networking. The research in particular deals with very advanced code that's way beyond my minimal knowledge of omnet. The first instruction to build the network is to run the makefile (found here: https://bpaste.net/show/d26a592a563a) to generate the "networkRL" needed by the python script.
I've imported all of the files needed for the simulation but whenever I try to run the makefile I get an error:
"Error starting process.
Cannot run program "C:\Users\Sierra\DRL\omnet\router\makefile": Launching failed"
Or when I try to run the entire simulation it asks:
"Enter parameter 'NetworkAll.node0.tcontroller.folderName':"
I'm not sure if these are simple problems to solve and I'm just inexperienced, but any help would be greatly appreciated. I can post all of the source, ned, and header files if necessary. I didn't want to pack this entire post with 15+ code links if the makefile was the only one needed to solve this issue.
I'm using OMNeT version 4.6 on Windows 10 if that information is relevant
The term "run the makefile" means: run make in the directory where makefile is located. In OMNeT++ one can do this in two ways.
First way:
Open mingwenv.cmd from OMNeT++ main directory.
In the mingw console go to main directory of the project, for example:
cd /C/Users/Sierra/DRL/
In the mingw console type:
make
Second way:
In OMNeT++ choose File | Import.. |Existing Project into Workspace and select the project.
Build the project choosing Project | Build Project.
According the second error: open omnetpp.ini and set value for folderName parameter, for example:
**.folderName = "/c/some/directory"
or
**.node0.tcontroller.folderName = "/c/some/directory"
I'm interested in learning about kde environment. So I read the contribution page on wiki, git cloned the kompare repo and built it. But an attempt to execute the binary gave me an error saying Could not load our KompareNavigationPart. The console showed the following error about kservice:
> ./kompare
kf5.kxmlgui: cannot find .rc file "kompareui.rc" for component "kompare"
kf5.kservice.services: KMimeTypeTrader: couldn't find service type "Kompare/ViewPart"
Please ensure that the .desktop file for it is installed; then run kbuildsycoca5.
kf5.kxmlgui: cannot find .rc file "kompareui.rc" for component "kompare"
Aborting aboutToFinish handling.
I couldn't find anything about it in the readme or the project wiki. I've installed the kde-development-meta package on arch linux. Can anyone help me get started with development on kde platform?
Short answer: Use "cmake -DCMAKE_INSTALL_PREFIX=/usr" and "make install".
Long answer: It looks like you tried to run from the build directory, but the KDE plugin loader does not look there by default. You could adjust the various path variables to additionally point to your build directory. The variables are mentioned at https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source#Set_up_the_runtime_environment
You can also use "make install" to install to a run-time directory. If you did not change the defaults of cmake via -D option, this will be "/usr/local/", and in this case you also have to adjust the various path variables to include that directory, unless your distribution already configured this for you.
I'm reading Foundations of Qt Development - by Johan Thelin.
Here quote from page 450 about Building QMake Project.
If you choose to create a Makefile using QMake, you can build your project using a simple make command (or nmake if you’re using Visual Studio). You can clean up your intermediate files using make clean. The slightly more brutal step is to run make distclean, which cleans up all generated files, including the Makefile. You will have to run QMake again to get a Makefile for make.
I tried hard to clean the files using 'make clean'. But cmd displaying the message 'make' is not recognized as an internal or external command, operable program or batch file.
I searched here and tried to find the PATH to make inside Qt directory. But not successful. Then according to this solution I tried to use mingw32-make also. But same results.
Anyone of you can help me?
If you using mingw32, try mingw32-make clean. Remember, you must add mingw's bin directory to User Enviroment to use this command. Follow "My Computer" > "Properties" > "Advanced" > "Environment Variables" > "Path" and add ;C:\Qt\Tools\mingw492_32\bin
OR
use command: setx PATH %PATH%;C:\Qt\Tools\mingw492_32\bin
I'm trying to get PyQt5 working with WinPython. PyQt5 comes with a readme file for installation, and I have unsuccessfully tried a few combinations of what I thought the first part of the readme tells me to do.
I have:
Windows 7 Home Premium 64-bit
WinPython-64bit-2.7.9.1
Qt 5.4
PyQt-gpl-5.4
PyQt-gpl-5.4 is in the folder (only partially sure that this is where I should have put it)
C:\WinPython-64bit-2.7.9.1\python-2.7.9.amd64\Lib\site-packages\PyQt-gpl-5.4
My current attempt at getting everything working is: I'm trying to run the configure.py file in PyQt-gpl-5.4, but when I do so I consistently get the following error:
Error: PyQt5 requires Qt v5.0 or later. You seem to be using v4.8.6.
Make sure the correct version of qmake is on your PATH.
What I think is the required version of qmake being referred to is in the folder
C:\Qt\5.4\mingw491_32\bin
However, I have no idea how to fix the error by adding the qmake in this folder to PATH. My most recent attempt was to add the folder using Spyder's Tools->PYTHONPATH manager, but this made no difference. I also tried adding it using sys.path.append('C:\Qt\5.4\mingw491_32\bin'), but this didn't work either. I have since removed the folder name from both of these locations.
How do I get PyQt5 working with WinPython-64bit-2.7.9.1, or I think equivalently, how to I get the configure.py file in the PyQt-gpl-5.4 folder to run?
Thanks.
You definitely don't want the source code (i.e. PyQt-gpl-5.4) in the site-packages folder, because that's where the compiled modules will end up. Instead, it should just go in a temporary folder whilst you compile it.
When you run configure.py, you must take care to use the executable for the specific python that you are targeting. I do not know anything about WinPython, but for a normal python installation this means doing something like this:
C:\Python34\python configure.py
As a first step, before attempting to actually compile anything, it would be advisable to take at look at all the configuration options that are available, like this:
C:\Python34\python configure.py --help
(There's also the Installing PyQt5 section in the PyQt Docs).
This will tell you, for instance, that the simplest way to specify the Qt installation you are targeting would be something like this:
C:\Python34\python configure.py --qmake C:\Qt\5.4\mingw491_32\bin\qmake
EDIT:
Sorry, that last part is wrong: the --qmake option isn't available on Windows, so you have to add the directory containing the qmake executable to your PATH. This can be done with the following command:
set PATH=%PATH%;C:\Qt\5.4\mingw491_32\bin
