I downloaded tbb40_233oss_lin.tgz file from http://threadingbuildingblocks.org/ver.php?fid=174
I set "TBBROOT" variable to the directory in my bash_proflie and I unzipped the tar file and navigated to the bin folder and run tbbvars.sh file
I typed
sh tbbvars.sh intel64
I was trying to run examples but it complains as shown bleow
count_strings.cpp:38:37: fatal error: tbb/concurrent_hash_map.h: No such file or directory
I tried to set up the library path manually and I typed
g++ file.cpp -o output -L/path/to/the/lib/-ltbb
but it still complains.
How do I compile the sample code on Ubuntu?
Thanks in advance.
I installed it from the Ubuntu repository, and it works without any problems.

I am trying to install opencv on my raspberry pi 4 with raspian OS.
I am using this tutorial https://docs.opencv.org/3.4/d7/d9f/tutorial_linux_install.html and I have navigated to a build directory in my source directory /home/icetea/Desktop/working_dir/opencv/build
Then I execute this command:
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/home/icetea/Desktop/working_dir/opencv
I get this error:
CMake Error: The source directory "/home/icetea/Desktop/working_dir/opencv/build" does not appear to contain CMakeLists.txt
It thinks the build dir is the source dir. My source dir does 100% contain that .txt file, but my build dir is empty. I have tried executing this command while in the source dir and I get this error:
FATAL: In-source builds are not allowed. You should create a separate directory for build files
Anybody have any insight?
Thank you very much

Any help on how I can solve this error:
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory
Basically, to find the file:
sudo find / -name libavdevice.so.52
For example, you've found this file in the /usr/local/lib. Next include that library into your library path. Add this to your /etc/ld.so.conf:
/usr/local/lib
And finally after modifying this file run this:
sudo ldconfig
Reference: Ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file

On installing yuidoc I'm getting the following warning.
npm WARN package.json connect#1.9.2 No README.md file found!
When trying to start yuidoc --server later it shows me:
info: (yuidoc): Scanning for yuidoc.json file.
error: (yuidoc): Scanned 5001 directories looking for a yuidoc.json file, something is probably wrong here..
Thanks for help!
The warning is nothing to worry about.
The error is that you haven't provided a yuidoc.json file:

I tried to go inside the directory by using the terminal.

I'm a newbie and want to know the reason.
would you explain it for me.

You need space, after command cd
cd ..
You missed the space in between cd and ..:
cd ..
You are missing a space, should be cd ..
