I have been working on OpenCV installation from the last 4 days but still can't find a way to install it without errors.
collect2: error: ld returned 1 exit status
apps/visualisation/CMakeFiles/opencv_visualisation.dir/build.make:104: recipe for target 'bin/opencv_visualisation' failed
make[2]: *** [bin/opencv_visualisation] Error 1

It shouldn't be too difficult:
# Get all the up-to-date tools you'll need
sudo apt-get update
sudo apt-get install git cmake build-essential
# Get latest greatest OpenCV from GitHub
cd
git clone https://github.com/opencv/opencv.git
# Go build and install that puppy
cd opencv
mkdir build
cd build
cmake ..
make -j 8
sudo make install
Maybe try running the file from this link. The good thing about this is that it abstracts so many things from you. You need not manually run all the commands. Run it on the ubuntu terminal as bash install-opencv.sh.
Just let me know incase of any errors.

I'm trying to build libsodium-sys dependency in an Azure Docker VM which is based on debian.
Have spend a couple of hours trying to fix this build error, but can't figure out what's going on.
I fixed a couple of build errors by installing missing dependencies as the Azure Docker VM seems very vanilla. Executed commands are below the error.
error: failed to run custom build command for `libsodium-sys v0.2.6 (https://github.com/cjdelisle/sodiumoxide?rev=76dc0e6e587b8c8a4bb193ebba9f8ae8f090b81b#76dc0e6e)`

I am trying to get this running https://github.com/Katou2/Optical_Flow_GPU_Opencv3 but am facing an issue where make does not detect my opencv_contrib module. Here are the steps that I have done up till cmake.
conda create -n opticalflow python=3.6 anaconda
conda activate opticalflow
git clone https://github.com/Katou2/Optical_Flow_GPU_Opencv3
cd Optical_Flow_GPU_Opencv3
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_CUDA=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules -D BUILD_TIFF=ON ..
And this is the output that I get with no error.

The problem comes when I run make.

So the error mentions that the file opencv2/cudaoptflow.hpp is not found and I read through https://github.com/open-mmlab/mmaction/issues/39 says that the error is due to the opencv_contrib module not having been installed. However, I am certain that I already have opencv_contrib installed because I have this command executed.
pip install opencv-contrib-python
and have also verified it as I am able to call the cv2.xfeatures2d method which requires opencv_contrib to run.
import cv2
help(cv2.xfeatures2d) # cv2.xfeatures2d requires opencv_contrib
I wanted to install pgAudit on my CentOS 6 32-bit, I already installed PostgreSQL 10 + pgAdmin4 from PostgreSQL Linux run installer that I downloaded from DBEnterprise
I followed the guide from here, here are the steps I followed :
git clone https://github.com/postgres/postgres.git
go into the folder by cd postgres and then git checkout REL_10_STABLE
./configure after that make install -s
cd contrib
Clone the pgAudit extension by git clone https://github.com/pgaudit/pgaudit.git
cd pgaudit
git checkout REL_10_STABLE
make -s check
make install
I'm stuck at step 8. Here's the result :
[root#localhost pgaudit]# make -s check
============== creating temporary instance ==============
============== initializing database system ==============
pg_regress: initdb failed
Examine /root/postgres/contrib/pgaudit/log/initdb.log for the reason.
Command was: "initdb" -D "/root/postgres/contrib/pgaudit/./tmp_check/data" --no-clean --no-sync > "/root/postgres/contrib/pgaudit/log/initdb.log" 2>&1
make: *** [check] Error 2
I opened the initdb.log at /root/postgres/contrib/pgaudit/log/initdb.log like how it told me to, and it says :
Running in no-clean mode. Mistakes will not be cleaned up.
initdb: cannot be run as root
Please log in (using, e.g., "su") as the (unprivileged) user that will
own the server process.
So I tried it again after I logged in as postgres, here's the result :
bash-4.1$ make -s check
make[3]: stat: ../../src/include/utils/errcodes.h: Permission denied
/bin/sh: line 0: cd: utils/: Not a directory

I'm really new to both Linux and PostgreSQL, so I don't know why it failed and what is the solution for this. Thanks in advance!
Look like your db user not having a login shell.
You can try with:
sudo -u postgres psql template
Or:
sudo -u postgres bash
I have installed mosquitto using the command apt-get install mosquitto. It is installed successfully on my system, but I got version "1.4.5". I want to downgrade to version 1.4.4, so I was trying using the source tar file. Under folder, I am running the command make and it is throwing an error:

make[1]: Entering directory `/home/ubuntu/org.eclipse.mosquitto-1.4.4/lib'

make[1]: *** [mosquitto.o] Error 1
make[1]: Leaving directory `/home/ubuntu/org.eclipse.mosquitto-1.4.4/lib'

What is going wrong here?. Is there any another way to install 1.4.4 version of mosquitto?
Thanks
You're missing dependencies needed for compilation.
Try:
apt-get install libc-ares-dev libssl-dev libwrap0-dev uthash-dev uuid-dev
If you want libwebsockets support you can either install libwebsockets-dev, or better install it manually from source - that will get you version 1.5 instead of the old 1.2 that is in Debian/Ubuntu.
If you install the manually compiled version with
make prefix=/usr install
then it will overwrite the existing binary and you can use it with the existing system services.
I'm cross-compiling the Dart runtime using the instruction here.
I've installed all the dependencies as specified. I've also cloned the git repository with the necessary tool chain.
I'm running the runtime compilation with this command:
./tools/build.py -m release -a arm --toolchain=../tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf runtime
The compilation starts with no problem then it stops with this error:

BUILD FAILED
Am I missing any dependency or package?
I hit the same problem. On my ubuntu 14.04 system /usr/include/asm didn't exist. It was called asm-generic instead. I sym-linked it and the build was able to continue.
cd /usr/include
sudo ln -s asm-generic/ asm
The build was able to continue after that.
This is probably because you're trying to build an application without some of the include paths correctly set, for example using a 32-bit gcc on a 64-bit platform.
To resolve:
sudo apt-get install gcc-multilib
I'm not sure why this happens, but sometimes /usr/include/asm gets deleted. My teammates who looked at their Ubuntu x86-64 workstations found that the asm symlink was:
0 lrwxrwxrwx 1 root root 20 May 22 2013 /usr/include/asm -> x86_64-linux-gnu/asm
And the command to recreate it is:
$ cd /usr/include
$ sudo ln -s x86_64-linux-gnu/asm asm
The files in /usr/include/asm-generic are sometimes, but not always, equivalent to the files in the x86-64 specific directory; so it's difficult to recommend symlinking it as a workaround.
