Installing janus-gateway error on CentOS7 - webrtc

I want to install janus-gateway on CentOS7.
I read the following document and tried installation.
https://github.com/meetecho/janus-gateway/blob/master/README.md
git clone https://github.com/meetecho/janus-gateway.git
cd janus-gateway
sh autogen.sh
./configure --prefix=/opt/janus
However, configuring janus-gateway will cause an error. The error is as follows.
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... yes
checking whether to build static libraries... no
checking for pkg-config... /bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for JANUS... no
configure: error: Package requirements (
glib-2.0 >= 2.34
libconfig
nice
jansson >= 2.5
libssl >= 1.0.1
libcrypto
) were not met:
No package 'nice' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables JANUS_CFLAGS
and JANUS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
I installed libnice(libnice-0.1.3-4.el7.x86_64) in the following way.
yum install libnice
How can I solve it?
Thank you.

try this and rebuild
echo "export PKG_CONFIG_PATH=/usr/lib/pkgconfig" >> ~/.bashrc
source ~/.bashrc

Disclaimer: I am using Ubuntu 18.04 when testing this.
If you are using Ubuntu system and trying to install Janus and running this code
./configure --prefix=/opt/janus
And then getting this error: No package 'nice' found
Make sure you have been installation of the nice from aptitude.
sudo install aptitude
aptitude install libmicrohttpd-dev libjansson-dev \
libssl-dev libsrtp-dev libsofia-sip-ua-dev libglib2.0-dev \
libopus-dev libogg-dev libcurl4-openssl-dev liblua5.3-dev \
libconfig-dev pkg-config gengetopt libtool automake
For some reason installation of nice using the answer from Frank, Ahmet or Zallfire doesn't work in Ubuntu. It has to be installed using aptitude.

You should download libnice source code to install.
https://gitlab.freedesktop.org/libnice/libnice

You need the development libnice.
yum install libnice-devel

Running CMake on Amazon Linux

I am trying to build OpenJpeg on an AWS Amazon Linux EC2 instance. I installed cmake and gcc and had no issues during installation. When I try to cmake openjpeg I get the following error:
-- Check if the system is big endian
-- Searching 16 bit integer
CMake Error at /usr/share/cmake/Modules/TestBigEndian.cmake:44 (message):
no suitable type found
Call Stack (most recent call first):
CMakeLists.txt:164 (TEST_BIG_ENDIAN)
-- Configuring incomplete, errors occurred!
Checking the error logs it seems CMake is unable to determine the size of integers, shorts and longs. The full error log can be found in this gist
How can I work this out and make CMake work?
Amazon has a guide: Preparing to Compile Software, which proposes the following command to install a C compiler.
sudo yum groupinstall "Development Tools"
Next, you can download and build Cmake yourself: Install Cmake 3.
wget https://cmake.org/files/v3.18/cmake-3.18.0.tar.gz
tar -xvzf cmake-3.18.0.tar.gz
cd cmake-3.18.0
./bootstrap
make
sudo make install
Note: the last make actually needs sudo.
This works in the most recent Amazon Linux image (Nov 2021):
# Install sudo, wget and openssl, which is required for building CMake
yum install sudo wget openssl-devel -y
# Install development tools
sudo yum groupinstall "Development Tools" -y
# Download, build and install cmake
wget https://cmake.org/files/v3.18/cmake-3.18.0.tar.gz
tar -xvzf cmake-3.18.0.tar.gz
cd cmake-3.18.0
./bootstrap
make
sudo make install
Though this does not actually answer why the error was happening but I was able to build OpenJpeg by building CMake from source. So I just removed Cmake which was installed via yum and I believe was 2.8.12. Downloaded the latest CMake3 sources (v 3.10) built Cmake and openjpeg and all my other packages with no issues.
You could try to set up a Docker container to replicate correct environment. This way, you could form a container on your local machine, make sure it all builds on the container environment, and later use this environment on the EC2.
There is a project on Github that provides a Docker image which can be used to compile for Lambda and test stuff locally. Have a look: https://github.com/lambci/docker-lambda

Not able to install mod_perl module on the server

In my site I am getting an error : an error occurred while processing this directive
It was working fine before moving to the new server. So when I checked I found that mod_perl module is missing. So I tried to install it by downloading the module to the server and then tried to run using Perl Makefile.pl but it was asking for apache src and I was not able to find it. I can see /usr/bin/apache/ folder but no source file inside the folder.
So I tried to install the module from Cpanel but I got the following error:
The C compiler is not functional and auto repair failed. Perl module installs require a working C compiler. Please repair the C compiler and try again.
Please let me know how to install it as I have tried most of the cases searching the net.
Thanks in advance
It's probably best to use your distro's packaging system to install mod_perl, especially, if apache is installed from a package too.
Yum based systems:
yum install mod_perl
Deb based systems
apt-get install mod_perl
you may need to enable the module using a2enmod
Mostly gcc is either corrupted or not present on your system. Please try to re/install gcc on your system
sudo apt-get update
sudo apt-get install build-essential
On Redhat:
yum update
yum install devtoolset-2-toolchain
It seems like a problem with your installation of gcc. You're using CloudLinux, so you should use yum to reinstall gcc.
$ sudo -i yum install gcc
But you don't need gcc if you install the pre-build packages.
$ sudo -i yum install mod_perl
Either way, you're going to need to get to grips with package installation for your system - and for that you're going to need root access.

cmake not working, could not exec qmake

I am using Ubuntu 14.04. I'm trying to install a program which requires cmake. When I run cmake src/ I get:
qmake: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory
What am I doing wrong?
Does the trick:
sudo apt-get install qt4-qmake
You do not need to install half a gigabyte of qt sdk!
I read on another post that the problem has something to do with CMake not being able to find Qt4 qmake.
However in my case, it was simply a matter of not having qt4-qmake. This solved it (but weighs a heavy 440MB):
sudo apt-get install qt-sdk
For newer versions of Ubuntu, if you have only installed version 5 of the Qt Framework, you may get this error. If you want to use Qt version 5 by default, then you should run the following command to fix the error:
sudo apt install qt5-default
You need the qt dependences:
sudo apt-get install qt4-qmake libqt4-dev
as it says in docs: https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#debian--ubuntu
sudo apt-get update
sudo apt-get install qt5-default libqt5webkit5-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer1.0-x
works for me in Ubuntu 18.04
You can use QtCreator to compile the cmake project too. This is only advantageous over the accepted answer if you already have QtCreator installed, I notice you are using a qmake project so this might be likely.
The main advantage of this is that qt creator will be configured to use the qmake tool without the need to install the command line configured version of qmake.
Incidentally, I get this error if I try to run the qmake executable bundled with QtCreator on the command line.

Configuration for Java binding for ZeroMQ (0MQ) with no root privileges on Linux

I am a novice with zeroMQ and I am stuck at binding ØMQ with java on a server running CentOS release 5.9.
Unfortunately, I do not have super user/root privileges on the server and am trying to install ØMQ as a normal user with restricted privileges. I have installed ØMQ by following instructions on http://www.zeromq.org/area:download
Make sure that libtool, autoconf, automake are installed.
Check whether uuid-dev package, uuid/e2fsprogs RPM or equivalent on your system is installed.
Unpack the .tar.gz source archive.
Run ./configure, followed by make.
Could not run the following obviously
To install ØMQ system-wide run sudo make install.
On Linux, run sudo ldconfig after installing ØMQ.
Then I attempted to install jzmq.
Cloned [git clone https://github.com/zeromq/jzmq.git]
Ran autogen.sh
Ran configure
At this point I get the following error
checking for ZeroMQ... no
checking zmq.h usability... no
checking zmq.h presence... no
checking for zmq.h... no
configure: error: cannot find zmq.h
As a result of the above error I am not able to run java tests and get error "no jzmq in java.library.path".
Can anybody help/direct me to how to get java binding for zeromq work when you dont have root privileges to install it? Its difficult to get IT department to install a new software on servers.
Appreciate your help.
Note: I do not have write permissions to /usr directory
Thanks
GBP
This can be overcome by adding --with-zeromq=/home/user/zeromq (installation directory of zeromq)
./configure --with-zeromq=/home/user/zeromq
Other steps include
export LD_LIBRARY_PATH=/home/user/zeromq/lib
You can also use JeroMQ (https://github.com/zeromq/jeromq) which is a pure Java implementation of ZeroMQ
I got this working by running autogen.sh on OEL 6 then running configure / compiling / installing on CentOS 5.9. I briefly looked into why autogen.sh was failing and the problem was the tool chain was too old. Since I had a more up-to-date system with a modern tool chain available running autogen.sh on something other than CentOS 5 was the easiest path for me. I'm sure it works fine with other modern Linux variants, I had OEL 6 at my finger tips.
I also did not have access to a standard directory for installation. To get that working I added zmq.jar to my class path, and the run-time linker needed to be able to find the zeromq and jzmq run-time libraries.
I faced the same issue on CentOS 6.5 and found that you need to install "gcc-c++" for this to work.
I used the following to install dependencies:
yum -y install jdk zeromq-devel unzip libtool gcc autoconf automake gcc-c++ python
Note that "jdk" comes from our private repository and it's same what can be downloaded from java.com
The following public repositories are installed on server:
atomic
Actually, I ended up having this same issue, and the following script worked for me, where I installed zeromq into ~ (so that I have ~/lib contains libzmq.a libzmq.la libzmq.so libzmq.so.3 libzmq.so.3.1.0 pkgconfig)
./autogen.sh ./configure --prefix=$HOME \ #because you don't have root privileges
--with-zeromq=$HOME --includedir=$HOME/include/ --libdir=$HOME/lib/
./make
./make -n install
#to check to see if it installs it to the right location
make install

Apache installation; libpcre error

When installing Apache on Ubuntu 11.10, I get the following error:
configure: error: APR not found. Please read the documentation.
I followed the instructions here, then, I get the error below:
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
What am I doing wrong and how can I resolve it?
1. Download PCRE from PCRE.org
2. Compile it with a prefix and install it:
./configure --prefix=/usr/local/pcre
make
make install
3. Go back to where your Apache installation is and compile Apache with PCRE:
--with-pcre=/usr/local/pcre
For me (Fedora Linux), it was enough to just install the pcre-devel: yum install -y pcre-devel. Didn't even have to use --with-pcre afterwards.
Debian
In a clean installation of Debian 9.5, during the installation of Apache it is necessary to have some packages and libraries to avoid errors. Next I show the type of error and its respective solution
Configuration
configure: error: no acceptable C compiler found in $PATH
$ sudo apt-get install build-essential
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
$ sudo apt-get install libpcre3-dev
Then I make the configuration indicating that it is installed in the path /usr/local and not in /usr/local/apache2, otherwise I will have library errors. The idea is that the libraries created for httpd end in /usr/local/lib so that the dynamic linker knows them.
$ configure --prefix /usr/local
Compilation
And for the compilation the following the installation of some packages also would avoid us errors in a clean installation of Debian.
xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory.
$ sudo apt-get install libexpat1-dev.
It is recommended to use the -j3 parameter to make the compilation faster. Although it could also be ignored.
$ make -j3
I was other problem compiling apache2 in CentOS with pcre. I installed pcre in other location "/custom/location/pcre" and configure command throw the following error
configure: error: Did not find pcre-config script at "/custom/location/pcre"
to solve it changing the flag --with-pcre=/custom/location/pcre to --with-pcre=/custom/location/pcre/bin/pcre2-config
BTW, on CentOS 7.6 before building httpd, please install pcre-devel
`$ sudo yum install pcre-devel`
In RHEL 3 is not necessary setting parameter --with-pcre pointing to pcre-config. Only need pcre path
My configure command:
./configure --prefix=/usr/local/apache2 --with-pcre=/usr/local/pcre
This worked for me:
sudo apt-get install libpcre3-dev
In ubuntu
This worked for me
./configure --prefix /u01/apache --with-included-apr --with-pcre=/usr/local/pcre/bin/pcre2-config
