I'm using Ubuntu 14.04 and I am updating the rpmbuild spec file of an application that now uses Qt.
The packages that I need are the following:
sudo apt-get build-essential
sudo apt-get install mesa-common-dev -y
sudo apt-get install libglu1-mesa-dev -y
sudo apt-get qt5-default
sudo apt-get qtwebengine5-dev
I know the spec file has "BuildRequires" and "Requires" dependency tags...any help in writing this as well as some examples would be helpful. I have a working spec file I just need to add the dependencies.
I think there is some confusion here. spec files are used to generate rpm files. However Ubuntu uses deb files.
Supposing you really want to create an rpm; then you need to know this:
BuildRequires
these packages are required for building the rpm. Typically you will need build-essential and the '*-dev` packages for building your application
Requires
these packages are required upon installation for your application to work; mostly you don't need your build-tools anymore, but you still need the qt5-default for example.
PS: on a little side note I might be one of the only people in the world building deb packages using spec files with a special conversion script https://bitbucket.org/klaussfreire/spec2deb/src/default/ but I wouldn't really recommend that.

I need to test if some firmware is compatible with older ethtool versions.
The machine I am using currently have ethtool version 5.16, but I need to install ethtool version 5.13
I got the compressed file from https://mirrors.edge.kernel.org/pub/software/network/ethtool/ and have used tar -zxvf https... to extract the files. This extracts a directory with the contents shown below:
After reading the INSTALL file, I ran ./configure but it gave me the following error: configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config
This meant that I could not run make or make install and thus am stuck.
After speaking to colleagues, the solution was found:
apt-get install -y pkg-config. Thereafter the following package was also needed: apt-get install -y libmnl-dev
Simple installed it with ./configure, make and make install and saw the ethtool version was as desired.
What does the yum and -y means
yum install httpd -y
new to fedora. please guide me.
the above code will install Apache server in fedora
yum is a software package manager that installs, updates, and removes packages on RPM-based systems. It automatically computes dependencies and figures out what things should occur to install packages. yum makes it easier to maintain groups of machines without having to manually update each one using rpm.
-y means that we did't want to gave yes to install any package (here httpd)
httpd installs apache web server
Thanks for Support and advice
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.
I just installed graphite on OSX, and managed to get the web app running this command:
python /opt/graphite/bin/run-graphite-devel-server.py /opt/graphite
I'll eventually move it to ubuntu, but in the mean time, some fonts are enormous:
Any thoughts on how to fix this?
I chased this down to an issue with the newest version of cairo. I removed cairo and installed 1.12.6. I posted the instructions here gist.github.com/relaxdiego/7539911
Its the cairocffi that handles the fonts and other display parameters. Sometimes installing only cairo doesn't work. In the above case you should always troubleshoot by ensuring proper and complete installation of the cairocffi package. By complete I mean all the dependencies for cairocffi.
The frequently required are:
1. libffi-devel (for rpm based operating systems)
sudo yum install libffi-devel
2. libffi-dev (for debian based operating systems)
sudo apt-get install libffi-dev
3. parse_lookup
sudo pip install parse_lookup
This is the Github page for cairocffi.
I have created ubuntu 10.04 ec2 image and now I need to install tomcat apache and jdk6 on my instance but whenever I use the command sudo apt-get install sun-java6-jdk or sudo apt-get install tomcat6 admin or sudo apt-get install ec2-api-tools
Package ec2-api-tools is not available, but is referred to by another package.
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ec2-api-tools is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package ec2-api-tools has no installation candidate
Another option is to add their official repository to apt - this will provide you up to date AWS tools:
sudo apt-add-repository ppa:awstools-dev/awstools
sudo apt-get update
sudo apt-get install ec2-api-tools -y
This is extremely useful for farther releases and and for up to date official bug fixes etc. just by running the usual
sudo apt-get update
sudo apt-get upgrade -y
Ubuntu doesn't have the Sun JDKs available by default so in /etc/apt/sources.list uncomment:
deb http://archive.canonical.com/ubuntu maverick partner
deb-src http://archive.canonical.com/ubuntu maverick partner
and then:
sudo apt-get update
sudo apt-get install sun-java6-jdk
ec2-api-tools requires the multiverse lines in sources.list to be uncommented first (remember to apt-get update also).
I am a bit confused, if you just want to install Java and Tomcat, why are you also trying to install the ec2 tools?
In any case, I also want to mention the free BitNami Cloud Tools installer (disclaimer: I am one of the developers). It includes the JDK and all EC2-related tools. We keep it fairly up-to-date and can run as a regular user.
