I'm trying to implement OCR recognition through Tessarect.
But at the moment I'm stuck with this error.
This is what I've done so far:
Homebrew tessarect
Download the API
Link the Jar with my project (build path > Configure build path > Add external Jar's
But when I compile my code this is the error
Error opening data file D:/Tess4J/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
Warning: Invalid resolution 0 dpi. Using 70 instead.
I've downloaded the eng trained data and I've tried different stuff but I can't figure out how to solve this.
I'm running eclipse in macOS Catalina.
Thanks!
My situation
Set your datapath correctly.
Your location D:/Tess4J/tessdata/eng.traineddata is wrong

I am trying to get Eclipse 4.11.0 running on my RHEL 6.10 system but it crashes when I try to run it. It points me to a log file that states:
...UnsatisfiedLinkError org.eclipse.swt.internal.gtk.OS._cachejvmptr()V
I tried running it again and it crashed again with a different log file entry:
...UnsatisfiedLinkError Could not load SWT library
It was looking for:
~/.swt/lib/linux/x86_64/libswt-pi4-gtk-4924r25.so
but the only file in that directory was libswt-pi3-gtk-4924r25.so
I also found libswt-pi3-gtk-4924r25.so in eclipse/configuration/org.eclipse.osgi/458/0/.cp.
I removed my ~/.swt directory and ran it again. Once again I got:
...UnsatisfiedLinkError org.eclipse.swt.internal.gtk.OS._cachejvmptr()V
I noticed that it made the ~/.swt/… directory structure and put the libswt-pi3-gtk-4924r25.so file in it so I tried to run it again and it (not surprisingly) gave me the following:
...UnsatisfiedLinkError Could not load SWT library
Does this have something to do with the version of gtk that I'm running on my system? Why does eclipse include the libswt-pi3-gtk.4924r25.so library in their installation, then look for the libswt-pi4-gtk-4924r25.so library?
Installing libgthread resolved the issue for me (SLES15, GTK3).
I'm trying to build my OwnCloud client. I'm using "Generic Build Instructions" from this link - https://doc.owncloud.org/desktop/2.5/building.html.
I'm stuck at 3 step with an error:
Could NOT find Qt5Keychain (missing: QTKEYCHAIN_LIBRARY)
I downloaded Qtkeychain and compiled it using this link - https://github.com/frankosterfeld/qtkeychain/wiki.
Everything is in my C disk. PATHS are set correctly. Can someone tell me what am missing here.
Adding PATH photo:
Adding a photo to be clear what am talking about:
How did you compile qtkeychain?
With the environment variable %QTDIR% set correctly, e.g. C:\Qt\Qt5.6.0\5.6\msvc2015, you should be able to compile qtkeychain
cmake -G "MinGW Makefiles" .
mingw32-make
and get a 32bit file named "libqt5keychain.dll.a".
You can then add the directory containing this file to your Windows path environment variable. This should work (it does for Nextcloud, at least).
I just try to update a project from Qt5.5.1 to Qt5.6 and now it fails during linking.

The programm compiled fine with QT5.5.1 using qbs.
Now I added the new QT Version and I get these errors.
I have no idea, why qbs adding two time the "lib" prefix, nor why qbs is trying to use it at all. This program should use the shared libraries of Qt.
Could someone give me a hint, how I can fix this? Or what the cause of the problem might be?
This issue was resolved in qbs 1.5.0.
I'm trying to use OProfile on Eclipse (3.8). The Juno version of oprofile didn't work, so I installed the Luna one. This one at least starts up, but can never find the libraries.
Here is the error:
ns3-dev-lena-profiling-debug: error while loading shared libraries: libns3-dev-lte- debug.so: cannot open shared object file: No such file or directory
profiled app exited with the following status: 127
I know that that means I need to add the library path. So I went to Profiling Tools Configurations, and specified the path under environmental variables as:
name: LD_LIBRARY_PATH
value: {workspace_loc:ns3dev2}/build (appended)
I manually checked and the library is located in the build folder. Furthermore, this library path works fine if I debug the same project instead (or run it...).
I've deleted the configuration and remade it, but it's the same error.
I also tried adding the same path to PATH instead of LD_LIBRARY_PATH, but that doesn't make any difference. (Just tried it for the hell of it).
Any thoughts?
Edit, I get the same problem on Eclipse 4.4 (Luna). I found the logs for the errors and the error is:
!ENTRY org.eclipse.linuxtools.oprofile.core 4 0 2014-10-27 12:33:07.200
!MESSAGE opreport process error output: warning: /no-vmlinux could not be found.
we are using PDFlib for personalizing PDFs.
The pdflib.jar library and the libpdf_java.so file are both in the folder:
/home/user/my/custom/library/path/
I start the server with this argument:
java -Djava.library.path=/home/user/my/custom/library/path/
like it is mentioned in the pdflib tutorial
After deploying on my jBoss5 Server i got this error message:
ERROR [STDERR] Cannot load the PDFlib shared library/DLL for Java.
Make sure to properly install the native PDFlib library. For your
information, the current value of java.library.path is:
/home/user/my/custom/library/path/
So, the path ist correct (i tried it with and without the / at the end)
If I put the jar and the lib in my /usr/lib folder, everything works fine, but not with my custom folders.
I use it on a linux 64bit, if that matters!
The custom folder and the files got chmod 755 - so this shouldn't be the problem
Looking forward to your hints!
