I'm installing Apache Spark which uses its own copy of SBT to set things up.
I'm using Linux Mint in a VirtualBox VM.
Here's a snippet from the error when I run sudo ./sbt/sbt compile from the Spark directory spark-0.9.0-incubating:
[error] (core/compile:compile) java.io.IOException: Cannot run program "javac": error=2, No such file or directory
[error] Total time: 181 s, completed Mar 9, 2014 12:48:03 PM
I can run java and javac from the command line just fine: e.g. javac -version gives javac 1.6.0_31
The correct jdk1.6.0_31/bin is in my PATH.
I read that the error might be due to the 64-bit JDK that I had installed, but I get the same error with the 32 bit JDK.
How can I sort out the issue?
edit: Using bash shell.
DISCLAIMER I'm mostly guessing now and still am unsure I should've responding here rather than adding a comment. Until it's clear, the DISCLAIMER remains.
When you execute java and javac from the command line, what user are you at that moment? I'm pretty sure your problems surface because the users you operate are different.
Please notice that you're executing sudo ./sbt/sbt compile as root (due to the way sudo works), but you say nothing about what user(s) you've been using to execute javac and java commands.
Add jdk1.6.0_31/bin to PATH for root and you'll be all set (as far as the configuration of Java's concerned).
I'd also recommend setting JAVA_HOME to point to jdk1.6.0_31 as it may help at times -- many applications are using it as the way to find the location of Java.
As a workaround, you may edit ./sbt/sbt and add PATH and JAVA_HOME appropriately.
You need to include the javac executable. To do this in Ubuntu please run the following command:
sudo apt-get install openjdk-7-jdk
It also places it within your path variable.

I am working in Ubuntu 16.04. I need to install gradle and the gradle is installed when i checked with sudo apt list --installed command but when i use gradle -version command it shows the following error,
JAVA_HOME is set to an invalid directory: /usr/lib/jvm/java-8-oracle/jre/bin/java
In sudo vim /etc/environment file,

I don't know where i made mistakes. Please help me.
Thanks.
On a 64bit openSuse 64 42.1 box;
readlink -f $(which java)
provided;
/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/jre/bin/java
But;
export JAVA_HOME=/usr/lib64/jvm/jre-1.8.0-openjdk
is the path that worked and allowed java emulator to run.
So i think we have to manually browse our file system and see what path to choose.
Today I faced this problem. I am using the default java that comes with your linux distro (so in my case, linux mint).
$ whereis java
This command gave me
java: /usr/bin/java /usr/share/java
So, I opened /user/bin. There was a link to Java. I right clicked it and selected follow original link. This lead me to /usr/lib/jvm/java-11-openjdk-amd64/bin/java.
So now that I know where this java is, I opened my .bashrc file, and edited the JAVA_HOME.
So for my case,
## My Custom variables
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
This solved the problem.
Now if you are using some other java (say you downloaded from oracle and extracted the zip file ...), then you have to add that location. So for example, if your java is in /home/user/.sdkman/candidates/java/current, then
export JAVA_HOME=/home/user/.sdkman/candidates/java/current
export PATH=$JAVA_HOME/bin:$PATH
I see a mismatch. In your enviornment file the JAVA_HOME is set to "/usr/lib/jvm/java-8-openjdk-amd64/" and your mentioned that the error that you got relates to the JAVA_HOME as "/usr/lib/jvm/java-8-oracle/jre/bin/java"
If you JAVA is really installed in /usr/lib/jvm/java-8-oracle directory, then you need to ensure that the JAVA_HOME is set to that directory. And also your PATH reflects $JAVA_HOME/bin in it.
I typically install Oracle JDK/JRE separately in a separate directory such as /usr/local/jdk1.8.0 etc.
check the jvm installtion folder from Files
eg : /usr/lib/jvm/java-12-oracle
then in terminal run sudo nano /etc/environment and add the line
JAVA_HOME="/usr/lib/jvm/java-12-oracle"
Then open terminal and run
export JAVA_HOME="/usr/lib/jvm/java-12-oracle"
Java JDK is installed, everything works great, also maven works great.
I followed the instructions from the site, downloaded the bat file, set the path and at the command prompt started the installation with the command lein self-install.
what i got in response is downloading leiningen now ....
after a while, C: \ windows \ system32> appeared below that line and it stays that way for several hours.
What more should I do?
The command line normally uses a prompt like > or similar to indicate it is waiting for a command. Then you type something followed by the <return> key:
> lein --version
Leiningen 2.9.8 on Java 1.8.0_322 OpenJDK 64-Bit Server VM
>
Here I typed lein --version, then <ret>, and the computer responded with a 1-liner about the version of Leiningen and Java that are installed. Then it displayed the prompt again, waiting for the next command.
You can use the cd (change directory) command to move around. With no prompt it will send you back to your "home" directory. See docs for the BASH or ZSH shell.
For Windows, I highly recommend installing the BASH Shell and git from this site:
https://gitforwindows.org/
IMHO the bash shell is greatly superior to the built-in Windows shell from CMD.EXE
I try to install the riscv tool to my Ubuntu 18.04.4 LTS server.
Use the following git repo and follow its build procedure:
spike simulator
GNU tool
Installation (Newlib)
riscv pk
Issue spike pk hello, gives me
Failed to run dtc: No such file or directory
Child dtb process failed
I have already installed the device-tree-compiler through apt command.
And checked with which dtc, outputs /usr/bin/dtc
What might be the problem?
Any help would be appreciated.
I run those commands on a command-line interface, not capable to run any graphic user interface. Not sure if that causes this problem.
The spike simulator is my first attempt to execute riscv code, I am also welcome to other recommendations.
I figure it out by creating a symbolic link using ln -s $(which dtc) and the problem is solved.
I have run into an ERROR with SBT today. It can best be shown with the sbt sbt-version command:

[info] Set current project to eric (in build file:/home/eric/)

No changes (that I know of) to either my SBT or Java setup.
Any ideas on what might be causing this or how to fix the error?
Thank you!
I had the same issue, especially when the TERM environment variable is set to xterm-256color. Setting it to a different value fixed the issue for me, e.g.
export TERM=xterm-color
I found the package which causes this issue: ncurses. I downgraded ncurses to version ncurses-6.0+20170429-1 (I am using Arch Linux) and SBT starts just fine.
Steps for Arch Linux:
cd /var/cache/pacman/pkg
sudo pacman -U ncurses-6.0+20170429-1-x86_64.pkg.tar.xz # or some other older version
Steps for Mac: see https://github.com/jline/jline2/issues/281
I think this issue was introduced with ncurses version 20170506, see: http://invisible-island.net/ncurses/NEWS.html#index-t20170506
+ modify tic/infocmp display of numeric values to use hexadecimal when
they are "close" to a power of two, making the result more readable.
I filed an issue on the SBT issue tracker: https://github.com/sbt/sbt/issues/3240
Edit: SBT version 0.13.16 includes the fix for this problem.
You can add export TERM=xterm-color to the top of /usr/share/sbt/bin/sbt because $HOME/.sbtconfig is deprecated.
sbt command is just a script. It load $HOME/.sbtconfig at the very beginning, so just put
export TERM=xterm-color
as #user3113045 said in the conf file, sbt will work. In that case your other term commands will still use xterm-256color.
This resolved the issue in my case (Linux Users):
Open your terminal
Navigate to your project directory
type "export TERM=xterm-color" in your terminal without the quotes
Hit ENTER
That is all and then you are good to go.
One year passed... now it happened to me.
So, ncurses did change, and the corresponding sbt part was ...I guess... probably only implemented based on random guessed tests and observations/bugs and not any spec nor RFC. (So far, sbt is the only program with this ncurses issue that I know of.)
In case you can't simply upgrade sbt nor downgrade ncurses, you could change the TERM environment variable as mentioned in the other answers.
trivial fix:
If your sbt script is some bash script (most likely, unless you run DOS' .bat files)
$ file /usr/bin/sbt
/usr/bin/sbt: Bourne-Again shell script, ASCII text executable
, then it might suffice to add this workaround:
TERM="${TERM/xterm-256color/xterm-color}"
If you can, change sbt version in build.properties to higher. 13.16 work for me.
For Ubuntu 20.04 Users, Open your terminal and run the bellow CMDs
Go to this "/usr/share/sbt/bin" directory ( $ cd /usr/share/sbt/bin )
give the permission to edit file ( $ sudo chmod -R 777 sbt )
Open the sbt text file in this directory ( $ nano sbt )
Add this "export TERM=xterm-color" cmd in top and save ( Ctrl + X )
Ex:-
#!/usr/bin/env bash
export TERM=xterm-color
set +e
I can't write a comment as my score is too low, but user3113045's answer worked when I added export TERM=xterm-color to my .zshrc file
I faced this issue when i am using activator which uses sbt internally.
I am using Ubuntu and this error was frustrating me.
I started facing this issue when i ran
$ activator gen-idea (tool which as per the intellij is legacy)
After this i tried to delete all the cache that this tool generated.
I deleted the .ivy and .sbt directories from my home folder and ran the activator cleanFiles compile command which resolved my issue.
My programming experience is about 1 year of C/C++ experience from high school, but I did my research and wrote a simple program with OpenCL a few months ago. I was able to compile and run this on an Apple computer relatively easily with g++ and the --framework option. Now I'm on my Ubuntu machine and I have no idea how to compile it. The correct drivers have been downloaded along with ATI's Stream SDK (I have an ATI Radeon HD5870). Any help would be appreciated!
Try
locate libOpenCL.so
If it is in one of the standard directories (most likely /usr/lib, or /usr/local/lib) you need to replace "--framework OpenCL" with "-lOpenCL". If g++ cannot find the lib you can tell g++ to look in a specific directory by adding "-L/path/to/library".
I wish I had my Linux to be more helpful... It is probably best if you redownload the ati-stream-sdk, after extracting it, open the Terminal and "cd /path/to/extracted/files"; in that directory execute make && sudo make install
make you probably know this from windows, this compiles, whatever needs to be compiled
&& chains commands together, the following commands will only be executed if the first command succeeded
sudo make install this will put the files in the expected places (sudo executes a command with superuser priviledges, you will have to enter your password)
Hope that helps.
You might be missing the dynamic libraries from the dynamic linker configuration.
Search for where the libraries are. Most likely /usr/lib, or /usr/local/lib.
Make sure the path location is also configured at one of these places:
LD_LIBRARY_PATH - you can set it in you environment shell, like .bashrc
/etc/ld.so.conf - you will need to call ldconfig to update the cache and it requires root access to change the file.
Reason
Aside from #bjoernz, my system can't find the libOpenCL.so file
It's because the correct file directory is missing
After searchig over the internet, I found out that libOpenCL.so file can provided by ocl-icd-opencl-dev package
Solution
You just need to install the package mentioned above by typing into cmd
sudo apt update
sudo apt install ocl-icd-opencl-dev
Therefore, libOpenCL.so can be found under /usr/lib/x86_64-linux-gnu/ folder
My System Information
OS: Ubuntu 16.04 LTS
GPU: NVIDIA GeForce GTX 660
GPU Driver: nvidia-375
