I have ElementaryOS installed. I am running Processing IDE in the terminal by running ./processing in the processing-3.3.4 directory. I'm getting this error:
java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory
This is a known issue that is being worked on. As of this moment, it doesn't look like they have released a fix, so I would try the previous version.
In the future, I recommend searching with Google for the specific error you're getting before posting to a forum. It can be hard to know what to search for, so here's an explanation of my process.
First I tried searching for "elementary os" processing cannot open shared object file "libjli.so" but since that didn't give me anything obvious, I assumed that this is not a widespread problem with Elementary OS. Note that I put quotes around "elementary os" and "libjli.so". This ensures that Google treats these as phrases, so pages with the word "elementary" and the word "os" will not match unless those two words are side-by-side.
Next I searched for processing ide cannot open shared object file "libjli.so" which gave me a link to the main Issues page on the github project. On that page, I searched for libjli.so which gave me one result, which is the issue I linked here.
I hope that helps you in the future.

So while attempting to install JDK via new task on task manager, it gives me the following error message:
Unable to install Java
There are errors in the following switches: "(1).exe";
Check that the commands are valid and try again.
I searched for the problem using "There are errors in the following switches" and turned up only one result which didn't help (surprising, considering the internet we live in today). Any and all diagnostic help is much appreciated, I've run out of things to try.
Note: Only this .exe is giving me issues, all other .exe s run fine.
(The original poster has probably moved on. This is for people who encounter the same problem and find this Q&A via a Google search.)
The Question does not include enough information to diagnose the problem. Based on the little that has been provided, I would consider the following:
Maybe the ".exe" came from a suspect source. Download it again from the official Oracle Java download site. (Don't trust 3rd-party download sites. They may be serving up an installer that is actually a trojan horse, or loaded up with bloatware...)
The executable name "(1).exe" is most unusual. Maybe it is the name that is causing the installer to get confused. If the name got changed when you downloaded the file, try changing it back to whatever it should be ... or downloading it again.
You didn't say clearly how you tried to run the installer. Maybe you actually did invoke it the wrong way; e.g. with /(1).exe as a "switch".
Should I attempt a manual installation? Placing files where they need to go.
No. Bad idea. The installer should work if you have a genuine one and you run it the right way.
I'm a total Java noob so please understand =) I need a quick advice on how to fix the issue.
I cloned the official selenium git repo, changed the code a bit (need to dump the page into some specified dirs), and tried to rebuilt it:
./go //java/server/src/org/openqa/selenium/remote/server:server:uber //java/client/src/org/openqa/selenium:client-combined:uber
It was successful but when I tried to execute it I got this:
$ java -jar build/java/server/src/org/openqa/selenium/remote/server/server-standalone.jar
Failed to load Main-Class manifest attribute from
build/java/server/src/org/openqa/selenium/remote/server/server-standalone.jar
Tried to check classpath, CLASS_PATH and CLASSPATH env variables (as a friend of mine suggested) - I simply don't have any.
At the same time, the pre-compiled standalone server from the official downloads works out of the box.
The official docs didn't help. There's nothing about it there.
So - I need a quick advice how to compile it? Thanks.
P.S. JDK 8 (latest), Mac OS 10.7
P.P.S. That friend of mine tried to build it by himself and he was lucky - he got a new build/dist folder where the target big file was. But in my case, the build folder is created, but there's not 'dist' folder in it.
Finally found the answer: I should have built it like that:
./go clean release
it's really strange that all the docs state I need to use these long /bla/bla/:uber things to get a whole single 'uber' server.
Update: The problem was solved with the help of MathWorks. I've published the answer below.
I need to control a program (Zemax) from Matlab. Unfortunately, Zemax only supports DDE for such control, which Matlab does not support any more. It works, but stops working on 64 bit platform after a few (presumable 63) DDE calls.
I wonder if there are working solutions. I could probably program a DLL with correct DDE support and then use DDE in Matlab via this DLL. This is a major effort for me. A more suitable solution would be to use Java DDE methods. Following another post here, I've discovered the JDDE library. However I cannot make it work: Even if I am in the directory with the DLL and JAR files, executing
import pretty-tools.JDDE-2.0.3.*
works fine but calling
a = com.pretty_tools.dde.client.DDEClientConversation()
afterwards (as done here) results in
Undefined variable "com" or class "com.pretty_tools.dde.client.DDEClientConversation".
I have very limited writing privileges on my PC, so I have added the javaclasspath.txt file with the jar/dll location to the directory indicated by prefdir. The file looks like this:
C:\Users\xxxxxxxx\Documents\matlab toolbox\jdde\pretty-tools-JDDE-2.0.3.jar
Calling javaclasspath shows a long listing with the last lines being:
...
C:\Program Files\MATLAB\R2012b\java\jarext\webservices\ws_client_core\mw-service-client-core.jar
C:\Users\kkarapet\Documents\matlab toolbox\jdde\pretty-tools-JDDE-2.0.3.jar
DYNAMIC JAVA PATH
<empty>
So path seems to be set correctly. What am I doing wrong?
With the help of MathWorks support, I've found the answer. Here is how to make JDDE work with Matlab 2012b, without admin privileges:
Download and unpack JDDE files (DLLs and JAR) into some folder. Let's say it's $path-to-jdde$\.
In Matlab, type prefdir. Open the resulting directory and create two files there, javaclasspath.txt and javalibrarypath.txt.
In javaclasspath.txt, add $path-to-jdde$\pretty-tools-JDDE-2.0.3.jar.
In javalibrarypath.txt, add $path-to-jdde$\.
Restart Matlab.
Now call ddeConv = com.pretty_tools.dde.client.DDEClientConversation; and start using the created object as described in JavaDoc. E.g. to connect to Zemax, run Zemax and then in call ddeConv.connect('Zemax', 'abc').
Step 2 above can only be done starting Matlab version R2012b. With an older version, if you have the write rights on the Matlab installation directory, you should be able to replace step 2 by editing the files librarypath.txt and classpath.txt in $MATLABROOT$\toolbox\local. I could not verify it so if you confirm it please let me know in the comment below.
I'm looking for a way to convert the javadocs from my open source project (generated in Eclipse) to GitHub MarkDown, or come up with some other simple solution to display my documentation on GitHub (shy of simply adding a docs directory). Is there a simple solution for this? Can I simply point the GitHub README.md to my docs directory? Is there something more elegant? I have been striking out on Google.
I don't think it's possible to make a usable Javadoc with MarkDown. The best solution is probably to commit the Javadoc you generated on the gh-pages branch (or in the docs/ directory depending on the settings of your project). It will be available at :
http://username.github.io/projectname
Here is an example from one of my projects:
http://ebourg.github.io/jsign/apidocs/
Currently you can also host your Javadoc with Github Pages from not only a gh-pages branch, but directly from the /docs folder within your master branch. You can check the help section on this topic, here (also check attached image below).
Also, there's a project on Github that targets some conversion of Javadoc to Markdown (have not tried it yet, just leaving the reference).
Do NOT check Javadocs into the source control for your project
Especially not into the master branch! I followed the other answers to this question for about a year before deciding it was a really bad idea. Why?
It made it too difficult to review diffs. I even made a script (see below) to update only the Javadoc pages that substantially changed, but it still was a mess.
It fooled IntelliJ's refactoring tools. I just tried to change .x() to .getX() and had to approve/reject every "x" in the Javadocs. Maybe I forgot to exclude the folder in IntelliJ, but if you ever use sed/grep/find on your project, you have to remember to exclude it every time.
It adds a bunch of data in git that just shouldn't be there, potentially making pull and clone commands take longer... FOREVER! Even if you later "remove" the folder, it's still stored in git.
Where should javadocs go?
It's probably best to post them on https://javadoc.io/, your web site, or AWS or heroku. If you must check javadoc into source control, make a separate project just for Javadocs so you'll never need to look at the diff. You can follow other people's answers for how to do this.
"I read your post, but I'm doing it anyway"
Here's my script to update fewer javadocs. It only copies files with substantial changes from the target/apidocs folder to the docs/apidocs folder. It also adds new files and deletes no longer used ones. I think I used poor names, newfile and oldfile, but it works. I mean, it wasn't enough to justify checking javadoc into my project's source control, but it helps.
#!/usr/bin/env bash
# -I means ignore lines matching a regular expression
# -q means "quiet" - only tell whether files differ or not
# -r means "recursive" - explore subdirectories
# -N means "treat absent files as empty" which makes absent files show up in Quiet mode.
diff -I '<!-- Generated by javadoc ' \
-I '<meta name="date" content="' \
-I '<title>' \
-I 'parent.document.title=' \
-N \
-qr \
docs/apidocs/ target/apidocs/ > target/javadocPatch.txt
# Now read in the output file created by the previous command and
# Update only files that have substantial changes.
while read ignore1 oldfile ignore2 newfile ignore3
do
if [ ! -f "$oldfile" ]
then
echo "Added $oldfile"
echo -n >$oldfile
cp -fu $newfile $oldfile
elif [ ! -f "$newfile" ]
then
echo "Deleted $newfile"
rm $newfile
else
echo "cp -fu $newfile $oldfile"
cp -fu $newfile $oldfile
fi
done < "target/javadocPatch.txt"
It might be a bit off topic but I believe what OP is looking for is a mechanism to automatically make javadoc available as a new version of the project is published.
If this is the case, then you can try: http://javadoc.io
It's a free service hosting javadocs for open source project, currently supporting maven central and bintray (jcenter).
You can generate a link to the latest version of your project. For example, this link https://javadoc.io/doc/org.springframework/spring-core always point to the latest version of spring-core, which is 5.2.0.RELEASE at the time I write this answer.
Declaimer: I run javadoc.io
Edit 01.02.2012:
FWIW: 4.7.0 linux packages are broken AFAIK, they
can be fixed or 4.6 packages used instead...
No need to use
custom Qt for Jambi – Smar 2 days ago
Thanks to SMAR, I was finally able to resolve this
issue by downloading the an older version of
qtjambi 4.6.3 ( http://qt-jambi.org/downloads/ ). The only problem was that the
designer did not know where to find my jvm which
I solved by adding these two entries to /etc/bash.bashrc:
# custom PATH exports
export JAVA_HOME=/usr/lib/jvm/java-6-sun
PATH=$PATH:$JAVA_HOME/bin
Then I just had to run (everything was in the qtjambi-folder):
designer.sh --> save it as .jui --> convert it with juic into a .java file --> and load it with netbeans :)
Hope this is somehow helpful to others too.
Thanks for the great and fast help!
Original post:
Good evening,
I am not completely sure if this topic is enough about programming but I am having some problems setting up Qtjambi. I have followed a lot of "howtos" and instructions so I am a little confused about what to do next. Qtjambi works as I have written a example program with netbeans. Although I have created some ui files that I want to implement which doesnt work.
I am trying to get this to run for like a week and I really need this because of my finals in 2 months. I try to give as much useful details as possible.
I am using LinuxMint (ubuntu derivate), downloaded qtjambi v 4.7.0
after trying out
bash qtjambi.sh
I got an error of mismatching versions
Cannot mix incompatible Qt library (version 0x40704) with this library (version 0x40700)
So I downloaded, compiled and installed
qt-everywhere-opensource-src-4.7.0 to /usr/local/Trolltech/Qt-4.7.0/
I know that I have to tell the system where to find all the binarys so I added to the /etc/bash.bashrc
#custom PATH exports
PATH=$PATH:/home/michi/Scripts
PATH=$PATH:/usr/local/Trolltech/Qt-4.7.0/bin/
export LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.7.0/lib
export QT_PLUGIN_PATH=/usr/local/Trolltech/Qt-4.7.0/plugins
JAVA_DIR=/usr/lib/jvm/java-6-sun-1.6.0.26/
export JAMBI_PATH=/usr/local/lib/qtjambi-linux64-community-4.7.0/
I followed through the instructions of:
http://www.davidlauzon.net/2010/01/getting-started-with-qt-jambi-on-linux/
Which generally talks about getting jambi-designer to work.
http://jpnurmi.kapsi.fi/blog/2008/03/16/how-to-switch-qt-version-in-ubuntu/
How to manage multiple Qt versions.. These commands worked but had no effect
I finally gave up on trying to run the designer and tried to "convert" the .ui files to .jui files with the program juic which is located in the qtjambi/bin folder. But also here I get an error:
michi#BALMORA ~/Documents/unterlagen/pr_scw/Qt/Qtrainer/test $ which juic
/usr/local/bin/juic
michi#BALMORA ~/Documents/unterlagen/pr_scw/Qt/Qtrainer/test $ juic -cp .
juic: no .jui files found in CLASSPATH
michi#BALMORA ~/Documents/unterlagen/pr_scw/Qt/Qtrainer/test $ /usr/locallib/qtjambi-linux64-community-4.7.0/bin/juic -cp .
juic: no .jui files found in CLASSPATH
It would be great if you could help/guide or redirect me to "better" instructions.
