I downloaded QwtPlot3D project from here
https://sourceforge.net/projects/qwtplot3d/files/
When I run qmake on the project file in the zip, I get following result:
WARNING: Unable to generate output for: C:/path/Makefile.Debug [TEMPLATE vclib]
QIODevice::write: device not open
Same when I try to build from QtCreator.
Any ideas ?
Thank you very much.
You are creating the file in a location that does not exist on the computer.
You could change the location of the folder to be created.

I've installed veins_inet project with omnet++ 5.0 and sumo 0.28. When I try to run the .ini on veins_example file this error appears:
Error in the module(omnetp::cModule) Scenario during network setup: Class Veins::VeinsInetManager not found
How do I solve this problem?
Is this the whole error message?
This kind of error can happen when the project is not properly created. To check that, verify if there is a folder named "Includes" in your project (you can see it in eclipse). If no, create a new project in Eclipse New | Project | OMNeT++, and paste your files there.
EDITED:
Hi all,
I used the Qt Documentations for creating an installer for my Qt app using Qt Installer Framework.
I think I'm at the final step. Please have a look at the issue:
I have a package_directory folder on my Windows Desktop with these sub-folders. The config.xml file contains this. The data subfolder contains the data.7z file. I then created a licens.txt file on my Desktop. The meta subfolder contains a package.xml file with this content.
Then I created a folder named Result on my Desktop and pasted the Cal.exe file from the Release folder onto it.
And finally Ran the following command:
C:\Qt\QtIFW2.0.3\bin\binarycreator.exe -c C:\Users\CS\Desktop\package_directory\config\config.xml -p C:\Users\CS\Desktop\package_directory\packages C:\Users\CS\Desktop\Result\Cal.exe
The installer was created in the Result folder. But I got the following message from the command line:
Warning: The <Name> tag in the 'C:/Users/CS/Desktop/package_directory/packag
es/com.vendor.product/meta/package.xml' is ignored - the installer uses the path
element right before the 'meta' ('com.vendor.product').
C:\Qt\QtIFW2.0.3\bin>
Should I ignore it? If not how to solve it, too, please?
The installer file exists in the Result folder on Desktop. When I install it and select a folder on Start Menu (say Accessories or Start Up) to have the shortcut of the program, no shortcut will be created or saved there!! :(
What is the reason for that problem and how should I solve it please?
so i downloaded codeblocks codeblocks-13.12mingw-setup-TDM-GCC-481.exe
when i try to run main.cpp i get this error message:
Failed to open 'C:\Users\$imba\Documents\Codeblocks projects\test\main.cpp'.
this is a detailed summary of what i did prior to opening main.cpp
i selected the defaults all the way through the end. I created a seperate folder (called Codeblocks projects) in my documents to save the projects in.
now when i went to create a new folder, i selected console application, C++ and then i named my project test. i decided to create the project in the Codeblocks projects folder that i created. the resulting filename comes out to be C:\Users\$imba\Documents\Codeblocks projects\test\test.cbd
i then selected
GNU GCC Compiler,
'Create Debug Configuration: Debug'
output dir: bin\Debug\
object dir.: obj\Debug\
i selected create Release configuration,: 'Release'
output dir.: bin\release\
objects output dir.: obj\ Release
Finish
when i double click on main.cpp is when i get the error message
Failed to open 'C:\Users\$imba\Documents\Codeblocks projects\test\main.cpp'.
please help, i need this program for my course.
Try saving it in a folder in C:\, like C:\Cpp\. Code::Blocks may be having problems with the space or the $ in the file path.
I just created a new folder CB-Project under my D: drive where I have codeblocks installed.
You may want to look in the directory that you have CB installed in first, you may also find this in program file (x86) or the codeblocks sub directory. Look for a file named that may have proj or project in it's name. If you don't find it you can just create a new folder. You will have to put the new folder name in the CB path so it will find it.
Hi while trying out jni example in this link http://wendro.blogspot.com/2010/03/jni-example-eclipse-dev-cpp.html?showComment=1309930446765#c5048550711511727724
with eclipse Helios windows xp am getting this error in eclipse console
"error: cannot access MyFirstWrapper,
class file for MyFirstWrapper not found,
javadoc: error - Class MyFirstWrapper not found.
Error: No classes were specified on the command line. Try -help."
what i have to do..???
Alternatively, set your run configuration's Working Directory to the project's bin. in the arguments, set flag -d to change where the output file goes to your cpp folder. For example:
Working Directory: ${workspace_loc:/ProjectRoot/bin}
Arguments: -d ${workspace_loc:/ProjectRoot/cpp} full.package.name.path.to.Class
Hi Thanks i only got the answer
i did like this i got a jni header file generated inside cpp folder
In Eclipse Run Tools, External Tools Configurations,
Name:Jni
Location:My javah.exe location
D:\ProgramFiles\Java\jdk1.6.0_17\bin\javah.exe
Working Directory: my javah file location
${workspace_loc:/jni_hello_world/cpp}
And the most important point is inside Arguments we have to give first as our .class location then jni command like below
-classpath E:\Workspace\JNI\jni_hello_world\bin
-jni MyFirstWrapper
