I install libopencv-dev package in Ubuntu 14.04,64bit.
After installation, I though the package should install the libraries and headers to /usr, but I can't find any libraries or headers.
Then I dpkg -L libopencv-dev, get those info:
igsrd#~>sudo dpkg -L libopencv-dev

Is that mean the package doesn't have any libraries or headers?
It shouldn't be that situation, right?
libopencv-dev is, as it's package description says, a meta package. It has dependencies to a number of packages that do contain the necessary libraries and header files, such as libopencv-core-dev, libopencv-imgproc-dev and so on.
Since dependencies are automatically installed, you indirectly have all you need. This is a standard pattern in packaging so you can either pick exactly the components you need or simply install the meta package.
If you are not sure, install libopencv-dev.

I'm trying to install the lualdap via luarocks with sudo luarocks install lualdap, but I am greeted with
Installing https://luarocks.org/lualdap-1.2.4.rc1-0.src.rock
Error: Could not find header file for LBER
No file lber.h in /usr/local/include
You may have to install LBER in your system and/or pass LBER_DIR or LBER_INCDIR to the luarocks command.
Example: luarocks install lualdap LBER_DIR=/usr/local
Notes:
I am on Lua 5.3.
I've installed OpenSSL and HTTP.
I've tried the LBER_DIR=/usr/local parameter.
I've looked around for what rock file I need to download to get this lber.h file, but am not having any luck with it. How can I get this lber.h file?
lber.h is not a file specific to Lua, but part of a library that needs to be installed on your system in order for the lualdap rock to be compiled.
On Ubuntu-like systems, you can install it with:
sudo apt-get install libldap2-dev
I have opencv 3.4.1 installed from source on my ubuntu. But when running command catkin_make -DCMAKE_BUILD_TYPE=Release I get error:

[EDIT] I get the same error compiling using clion or catkin_make directly from terminal, but clion creates special packages for release and debug versions. I don't quite understand these packages but in files CMakeCache.txt i found folowing lines:

I don't understand what these metrics_lib_LIB_DEPENDS are, and from where do they come from.
I also used erroneously sudo find / -name "opencv" -exec rm -i {} \; to remove opencv and I had the same problem.
I solved with :
sudo apt remove libopencv-dev
sudo apt remove libopencv-core3.2
However not all the opencv lib will be unistalled with this, so you need to remove all the opencv lib installed with ros (in my case I needed to remove also opencv-data). You can find them with:
sudo apt list --installed | grep opencv
after that you can install again ros melodic (or whatever you are using) :
sudo apt install ros-melodic-desktop-full
Problem was that I uninstalled previous version of opencv via next command:
sudo find / -name "*opencv*" -exec rm -i {} \;
By doing this I also erased the contents of the ROS OpenCV library. Later even after reinstalling ROS, these libraries did not reinstall because the system thinks they are installed but nothing was in them. I had to apt-get each library individually.
Don't purge OpenCV...
I want to install MongoDB C++ Driver, so first is mongocxx
I follow this installation:
http://mongocxx.org/mongocxx-v3/installation/
but I can not pass step 4
when I run this in mongo-cxx-driver/build
sudo cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
it shows
-- Auto-configuring bsoncxx to use MNMLSTC for polyfills since C++17 is inactive

second question,
Step 2: Choose a C++17 polyfill how can I set MNMLSTC/core?
does anyone can help me,I already trap here for a long time ?
my env:
mongo-c-driver 1.15.1
libmongoc-1.0
mongocxx-3.4.x
Cmake is complaining about not finding a package configuration file (xxx.cmake), probably because you didn't build libmongoc/libbson.
I've tried to reproduce your issue and hit the same problem when I only installed them (apt-get install), so my suggestion is that you get the sources and build them as described at: http://mongoc.org/libmongoc/current/installing.html
Here's the list of commands (with the latest version of mongo-c-driver=1.15.1) which I just tried and worked fine:
wget https://github.com/mongodb/mongo-c-driver/releases/download/1.15.1/mongo-c-driver-1.15.1.tar.gz
tar xzf mongo-c-driver-1.15.1.tar.gz
cd mongo-c-driver-1.15.1
mkdir cmake-build
cd cmake-build
cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF ..
make
sudo make install
At this point you can go back into mongocxx/build and run again the command you were stuck at:
cd ../../mongo-cxx-driver/build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
In the institute we use Scientific Linux 5 on the cluster and I need to deploy an app that uses a modern OpenCV distribution (2.3.1 or 2.4.0). I don't have root privileges on the cluster.
Essentially, how do I package all the dynamic binary dependencies of ffmpeg (and hopefully x264), opencv so that I can xcopy-deploy my app?
I have a working installation of OpenCV 2.3.1 on Ubuntu. If there was a way to controllably load the executable and copy along all the dynamic dependencies, I could use it.
Thanks,
Vadim
You don't need to install OpenCV in the computers if you don't have permission to do so.
Place the OpenCV libraries and it's dependencies somewhere in the system and before you execute your application make sure you adjust LD_LIBRARY_PATH to add these paths.
To retrieve the list of dependencies of a certain binary application/library, use ldd. You might be interested in reading this post: Copying shared library dependencies
1) Install GCC 4.7.3
sudo apt-get update
sudo apt-get install build-essential
2) Install CMake 2.8.10.1
sudo apt-get install cmake cmake-curses-gui
3) Download OpenCV 2.4.5
cd ~/Downloads
tar -xf opencv-2.4.5.tar.gz
cd opencv-2.4.5
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j4
sudo make install
cd ../..
rm -rf opencv-2.4.5*
OpenBR uses OpenCV for face recognition. A clear documentation is available to install OpenBR,Here's the link!
I have been trying some different java compilers over the weekend and decided to stick with javac this morning. I then proceeded to clean up the mess that was caused by my testing and removed every last trace of java and did a fresh 'apt-get install openjdk-6-jdk' after autoremove and autoclean.
The following weirdness was then encountered:
tarskin#5-PARA-11-0120:~$ javac
The program 'javac' can be found in the following packages:
* openjdk-6-jdk
* ecj
* gcj-4.4-jdk
* gcj-4.6-jdk
* gcj-4.5-jdk
* openjdk-7-jdk
Try: sudo apt-get install <selected package>
I had allready installed openjdk but i tried it anyhow yielding:
tarskin#5-PARA-11-0120:~$ sudo apt-get install openjdk-6-jdk
[sudo] password for tarskin:
Reading package lists... Done
Building dependency tree
Reading state information... Done
openjdk-6-jdk is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
tarskin#5-PARA-11-0120:~$
I know i must be doing something stupid but I have no idea what, if anyone else could give a pointer in the right direction that would be very much appreciated...
Cheers
EDIT: Found some other weird aspects about the 'new' instance of my java distro, it doesn't seem to recognise for example 'Pattern' or 'Matcher' that should be coming from the regex import shrugs.
TL;DR: install java-1.6.0-openjdk-devel
I had a similar issue on Fedora, but used rpm -q -l to list the contents of the (pre-installed) java-1.6.0-openjdk package, and discovered that it doesn't include javac. It is in fact only a JRE, not a JDK, as implied by the installation instructions on http://openjdk.java.net/install/ . To get javac, I installed java-1.6.0-openjdk-devel . Not exactly what I expected, because the usual packaging conventions would indicate that is the package for doing openjdk development (i.e., working on the JVM), not for developing programs with it.
Basically, openjdk's package naming doesn't follow either standard Java conventions (would require calling it a JRE somewhere), or standard Linux packaging conventions (using -devel indicates it is used for developing the package w/o -devel itself).
As per http://openjdk.java.net/install/, to install the OpenJDK-6 JRE only:
$ sudo apt-get install openjdk-6-jre
To install the full JDK:
$ sudo apt-get install openjdk-6-jdk
Check /etc/alternatives and /usr/bin. One or both will contain links to old Java versions which you had installed. When those links are broken, you can get the error message above.
To update the links after installing a new version of Java, try update-alternatives
First to check if javac is installed try to look for that file:
1. locate javac
2. or find / -name javac
And also you can check at this website with instrucions on how to install java on Ubuntu (i suppose you are on ubuntu):
http://openjdk.java.net/install/
You can also check:
http://packages.ubuntu.com/hardy/i386/openjdk-6-jdk/filelist for the files installed by the pacakge, and you can notice that javac should be installed.
Maybe you also need to run:
Open the terminal and run this command to install OpenJDK 7.0 on Ubuntu Oneiric:
sudo update-alternatives --config java
