When I run the Twain implemented framework I get this error: NO TWAIN DATASOURE IS NOT INSTALLED. I am using Window7 64-bit. I downloaded some drivers from SourceforgeTWAIN DSM FILES.
The download directory contains:
TWAINDSM.dll
TWAINDSM64.msm
I copied the TWAINDSM.dll file into C:\Windows\SysWOW64. My doubt is how do I get the twain relevant .ds files.Iam don't know about dotnet relevant stuff. Please help me.
You can download TWAIN sample data source here.
The DSM and DS are different. The DSM looks for data sources.

Trying to build qt5 with buildroot. I need to download the source so that everything is compiled through the cross-compiler.
One of my project relies on the 'Config-file Packages' (CMake helper config file) provided by Qt5 in the binary tarball at this location Qt5.8.0/5.8/gcc_64/lib/cmake.
Problem: I can't find that folder anywhere in the source. When I take one example file (e.g. Qt5Config.cmake), I can't find any git repo hosting it.
Had a look at Ubuntu packages and it is being distributed in qtbase5-dev. When I look at this package documentation, it says it is using qtbase-opensource-src 5.5.1+dfsg-16ubuntu7.4 as the source package. Had a look at the source package for 5.8 but the cmake files are not there.
I could upload those files in an ad-hoc git repo, but that just seems weird that those files are not hosted by the qt repo.
What am I missing?
The cmake files are generated while build. On Linux the results are installed to qt/lib/cmake.
I downloaded Qt5.6 VS2013 32bit and try to run the official example of QtWebEngine.
I just followed the instruction but
When linking it gives out an error of
LNK1104 file not found c:\Users\qt\work\install\lib\Qt5Widgetsd.lib.
However, I have no idea of where this path c:\Users\qt\work\install\lib\ comes from.
I did text search in all directories of example folder and no hits other than generated files(makefiles and pdbs).
I also checked system environment variables but no hits.
Furthermore, I checked Qt Creator'r Projects panel and its Build Environment and still no hits.
Did I miss something?
P.S. this error was given out by linking DemoBrowser example of QtWebEngineWidgets pro
The link is generated by qmake when it generates the build scrip from the qt project file (*.pro). It is based from the qmake application path that is generaly installed together with the libraries (check you qt kit setup to change it if needed: Jst browse to qmake.exe application).
Then try regenerate the build script. It should fix the issue.
You may also have issue with installation not being in debug mode; you are trying to use Qt5Widgetsd.lib library instead of the non-debug one Qt5Widgets.lib
I just installed Qt, Qt creator and g++ on the latest version of Mint, and attempted to compile the default hello world project. After configuring a compiler kit I get the following error:
bits/c++config.h: No such file or directiry
/usr/include/c++/4.7/utility
No surprise there is no such file at that location. It appears this is some sort of config file where you specify what architecture you're compiling for.
What package do I install, or how do I write or generate this config file?
c++config.h is not in /usr/include, but rather in an architechture-dependent path. What you need is one of the libstdc++ development packages. You have not specified your platform details but my guess is that what you need is libstdc++6-4.7-dev as the error message refers to 4.7. See full list of packages containing c++config.h under Ubuntu and Ubuntu-likes here.
I don't know of a specific package search for Mint but the Ubuntu one has hit the nail on the head for me.
edit: ah drat, I only noticed this was 8 months old immediately after I posted the answer. Is this bad?
I have no idea why, but when i export my java program into a Jar it just wont run. There are no errors when building or running it. When I run the program through eclipse it work perfectly.
Anyone had this problem before or care to take a look?
regards,
Matt
As Shark said, it has to be exported as an Executable JAR file. Just exporting your project to a JAR is insufficient.
Here's a nice write-up on making Executable JAR files:

If you want to make it from Eclipse, Export as Java | Runnable JAR.
windows 8 installed java 1.6 without the correct paths. I installed jdk 1.8 and it worked.
I am trying to compile the SpeechMe project: http://projects.developer.nokia.com/speechme/wiki so that I can use the voice recognition in another project I want to make.
I have followed all the instructions and downloaded the full sources of Sphinxbase and Pocketsphinx and used them to add all the missing files to the Sphinxbase and Pocketsphinx directories included in SpeechMe. I have compiled them all in the order the wiki says and they all returned: "***Build Complete" but it seems that they did not produce any output files?
I then tried compiling SpeechMe in Qt Creator but it gives me these three errors:
Here is the build log for all configurations: http://sdrv.ms/PxlD6r
Please help, I really don't understand why this is not working!
I'm guessing Carbide should have created those 3 files when compiling but it didn't, any ideas why and what I can do to fix it?
Files must be created inside pocketsphinx tree but they shouldn't be placed in the required location. Most likely you need to find library files and put them into the required folder manually.
Another reason might be that you are compiled a debug version of pocketsphinx while the latest project is looking for a release version of the libraries.
