I downloaded vagrant for Windows at this link

I have just installed Vagrant on Windows 7 64 bit. When I type vagrant up to start it, it displays the following error below at command prompt. How do I upgrade from version 2 to 3
C:\hhvm-vagrant>vagrant up
Vagrant failed to initialize at a very early stage:
The version of powershell currently installed on this host is less than
the required minimum version. Please upgrade the installed version of
powershell to the minimum required version and run the command again.
Installed version: 2
Minimum required version: 3
It was resolved by installing windows management Framework version 3.0
If you update the powershell version to 3.0, the problem will be resolved.
I have developed a qt application on Ubuntu 16 but for testing I need to run it on redhat 5. But I am using c++11 standard features in my code and gcc (very old version on redhat) does not recognise this. I need to know is it possible to install gcc version (anything above than 5.0) on redhat 5?
I have already searched online but most of the links take me to redhat 7. Please note that I cannot upgrade to rhel 7.
As I can see HDP 2.2 needs Centos 6.5 as an operation system, probably because Ambari needs Centos 6.5. My question is if anyone has installed it on Centos 7. Is there any hard dependencies that will not allow me to complete the installation successfully?
Ambari 2.2+ can be installed successfully and works fine on CentOS 7. Then you can install HDP 2.0+.
As far as I'm aware there are no hard dependencies, per se. However Ambari itself looks at the operating system version, and if its CentOS 7, it'll stop the install.
In order to work around that you'd need to edit Ambari's source code.
Just consult the official Installation Guide for a relevant Ambari version
https://cwiki.apache.org/confluence/display/AMBARI/Install+Ambari+2.2.0+from+Public+Repositories
It's an up-to-date source of OS compatibility information.
Here you can see that Centos 7 is officially supported.
I want to use GCC 4.8.1 or higher on a HPC machine with CentOS 6.5 which has a very old GCC. I do not have admin rights so everything has to be local. Do I have to really compile everything from source? Isn't there any rpm package that I can only install GCC with its dependencies? I found GCC rpms for CentOS 7 but not 6.5.
Without admin rights, building from source is
likely most reliable means to use gcc-4.8.1.
You can try installing (or extracting) gcc-4.8.1
from the redhat developer tool kit 2.0 described here
https://superuser.com/questions/381160/how-to-install-gcc-4-7-x-4-8-x-on-centos
CentOS 7 RPM's are unlikely to work in general on CentOS 6.x.
The developer 2.0 toolkit was built on CentOS6
I was wondering if it is possible to install kernel 3.9 in Debian Jessie from repos. A brief check shows that there are only 2.6, 3.2 and 3.13 kernels in repos Compiling my own kernel is the last thing I want to do.
Btw I need kernel 3.9 in order to install Catalyst 3.12, because I am having serious problems with Catalyst 14.3 and I cannot install Catalyst 3.12 on kernels>3.9.
Thank you!
