I'm new to R and I use Eclipse a lot so I decided to install the StatET plugin in eclipse. Everything went smoothly except that I have the same problem as shown here...
Random true facts:
Windows XP Version 5.1.2600
Eclipse 3.6
StatET 0.9.2
I tried to install rj-0.5.2-1 from here, which is the package recommended for StatET 0.9.2. I put the tar.gz file in the same directory as R.exe and successfully installed it, here is the command line output...
H:\DATA\R\R-2.13.0\bin>R CMD INSTALL --no-test-load rj_*.tar.gz
* installing to library 'H:/DATA/R/R-2.13.0/library'
* installing *source* package 'rj' ...
** R
** inst
** preparing package for lazy loading
** help
No man pages found in package 'rj'
*** installing help indices
** building package indices ...
* DONE (rj)
H:\DATA\R\R-2.13.0\bin>
When it was done I could see the rj folder in the H:\DATA\R\R-2.13.0\library folder, so I thought it worked. However when I start Eclipse and start the RJ console I still get this error message...
[INFO] The R package 'rj' is not available, R-StatET tools cannot be initialized.
I also tried installing the rj-0.5.5-3 package since the binaries are precompiled; however, that didn't work either. I still get the same error message.
I noticed that at the bottom of the stackoverflow page I posted above that there is a post by Allan Stokes that states this error message is not true. Is this correct? How can I tell if this error message is a Eclipse/StatET bug or that my rj package is not installed properly? Any ideas?
Not sure if it is allowed to answer your own question, but I managed to get it working and I thought I'd post my solution. For some reason R was not recognizing the rj library when it was installed on my H: drive which is a portable drive, not my system drive. I uninstalled R and reinstalled it on my C: drive, which is my system drive. I installed rJava and rj just like before and in the r console I ran...
("rj" %in% installed.packages()[,"Package"])
it returned true indicating that the package was there, this command returned false when R was installed on my H: drive. I went into Eclipse/StatET and setup my R environment with the new location of R and ran RJ and there was no error. I'm not sure why this solution worked. Maybe the rj package need to be installed in a very specific manner. I don't understand why some libraries worked on the H: drive and some didn't. The rJava package would work on the H: drive and that the rj package wouldn't. Why is this? Ah well, it's working now. The info on this mailing list helped a lot...

After I upgraded Netbeans from 12.6 to 13, Netbeans doesn't start. When I start it from the command line, I got the following message:

What's the reason? How can I fix it?
This is caused by old nb-javac (Netbeans Java Compiler) modules installed in an older Netbeans version, which are incompatible with nb-javac, which is now bundled in Netbeans.
It's necessary to remove those old modules. You can find them in the Netbeans user directory. On Linux this is for example in ~/.netbeans or in ~/snap/netbeans/current, if installed as a Snap package. Those nb-javac files are in the modules directory in that directory (e.g. ~/.netbeans/modules) and include nbjavac in the name, e.g. org-netbeans-modules-nbjavac-api.jar. Delete all such files that include nbjavac. Then start Netbeans again, all should work now.
This problem was reported for a development version of Netbeans 13 on the developers' mailing list: https://www.mail-archive.com/dev#netbeans.apache.org/msg09777.html. There are original instructions that helped me to fix this issue. I wasn't using any development build of Netbeans, I just upgraded from the regular version 12.6 to the version 13 of Netbeans. In Netbeans 12.6, I installed the nb-javac plugin, which probably brought these incompatible modules that needed to be removed.

I am using Windows 10 and Strawberry Perl. I found this nice tutorial on building a 3D engine in Perl. Which requires SDL. For a couple of days I've been trying to install it, but it doesn't work. First I tried via CPAN, no success. No I am trying manually, but I am getting error messages when using "make". If I type "perl -V:make" it says I should use "dmake". If I do so, there's a dmake warning, telling me to use gmake instead. If I do that, there's the following message:
"to undefined at C:/Perl64/site/lib/ExtUtils/Install.pm line 1199. gmake: *** [Makefile:942: pm_to_blib] Error 2"
Any suggestions how to fix this? Or is there an easy (easier) way to install SDL?
It seems like the Perl SDL module uses SDL version 1.2.14, whereas the documentation says
The best course of action is to move to SDL 2.0 or later as quickly as
possible
So, I would recommend looking at the Python bindings PySDL2 instead. The following worked for me on Windows 10:
Downloaded Python 3.8 from here:
https://www.python.org/ftp/python/3.8.2/python-3.8.2-amd64.exe
Then added the following to the User enviroment variables for "Path" (NOTE: at the beginning, not at the end):
%USERPROFILE%\AppData\Local\Programs\Python\Python38
%USERPROFILE%\AppData\Local\Programs\Python\Python38\Scripts
Then, from the command prompt install pysdl2:
>pip install pysdl2

Then, add a new User environment variable PYTHONPATH with value:
%USERPROFILE%\AppData\Local\Programs\Python\Python38\Lib\site-packages
Close the command prompt, and reopen a new one to update the environment variables. Then I created a test Python script:
import sys
import sdl2.ext
resource_dir=r'C:\Users\hakon\AppData\Local\Programs\Python\Python38\Lib\site-packages\sdl2\examples'
RESOURCES = sdl2.ext.Resources(resource_dir, "resources")
sdl2.ext.init()
window = sdl2.ext.Window("Hello World!", size=(640, 480))
window.show()
factory = sdl2.ext.SpriteFactory(sdl2.ext.SOFTWARE)
sprite = factory.from_image(RESOURCES.get_path("hello.bmp"))
spriterenderer = factory.create_sprite_render_system(window)
spriterenderer.render(sprite)
processor = sdl2.ext.TestEventProcessor()
processor.run(window)
sdl2.ext.quit()
and finally run it from the command prompt:
> python test.py
I installed the jre7 and jdk1.7 and android sdk and avd manager perfectly my emulator is working properly but when i run the program which i wrote it is showing

I am using basic4android in my laptop without any problem but in case of my desktop system it is showing the above error...
I have understood from Erel that this is fixed with Basic4Android v2.50 or above. One can also instead install the latest Java 6 version and use it for compilation.
The use of Java 6 was successful in my case.
I think that the problem is with the jdk that you are running. Try with jdk1.6.0_25. I use this one and never update this version because the version 7 have some issues with security.
I have a Synology DS212j NAS (cpu Feroceon 88FR131 rev 1 (v5l)) with the optware ipkg installed. I am trying to build mongo-nonx86 on it.
"scons all" gives me the following messages:
scons: Reading SConscript files ...
scons version: 2.0.1
python version: 2 5 6 'final' 0
Checking whether the C++ compiler worksyes
Checking for C library stdc++... no
can't find stdc++ library which is needed
I have the stdc++ library installed, I also have ssl installed. My underlying question is how can I get scons to tell me more about what is really missing, where it is looking, how it is looking etc. I have so far found no options which generate any more useful diagnostic output?
Obviously a ready-made solution for getting mongodb working on this great little box would be even more welcome :-)
Well even if you do have it installed, it doesn't seem to think so, here is what I would try to do, install libssl-dev, then try to install the dev package for libstdc++, which is: libstdc++-dev.
Then see if you can compile it.
I realize there are several posts on this, so apologies if I'm breaching etiquette. In my case, I've tried several of them, and I just can't seem to get the rj issue (of having it installed properly) resolved.
I tried the CMD INSTALL recommendation and literally copied the tar file to my R executable directory
R CMD INSTALL --no-test-load rj_*.tar.gz
I used a DOS cmd window to run it, and it failed using the * notation, so I substituted the exact rj tar file name by navigating to the path...
C:\Program Files\R\R-2.12.1\bin\x64\rj_0.5.0-5.tar.gz
and running
R CMD INSTALL --no-test-load rj_0.5.0-5.tar.gz
This seemed to work as R shows all Java packages installed (inc. Rjava)
> ("rj" %in% installed.packages()[,"Package"])
[1] TRUE
> ("rJava" %in% installed.packages()[,"Package"])
[1] TRUE
>
Yet, in the eclipse environment, I'm still getting rj missing error.
Any thoughts on what to try next? I really want to get the debug capability to work here and pulling my hair out over this.
Oh, and also even though it shows installed in R. If I try to launch inside R, I get:
> library(rj)
Error : .onLoad failed in loadNamespace() for 'rj', details:
call: .jcall("de/walware/rj/server/RJ", "Lde/walware/rj/server/RJ;",
