Ubuntu with both 32bit and 64bit libcurl - 32bit-64bit

Im running a c++ application and Asterisk in 64bit Ubuntu machine.My C++ application needs 32bit libcurl. And Asterisk needs 64bit libcurl to do some http calls in the dialpaln.Can I keep both 32bit and 64bit libcurl in the same machine and config asterisk to lookup for 64bit libcurl?

You can have on linux both 32 or 64 libs. 32bit apps will use libc.i686 and 32bit libs, 64bit apps will use 64bit libs.

Install kaa single-node 0.10.0 or 0.11.0 on Ubuntu 18.10

is Kaa single-node compatible with Ubuntu 18.10?
If i install on Ubuntu 16.04 it works, on Ubuntu 18.10 everything seems starting right but when i try connecting to http://localhost:8080/kaaAdmin it shows that "it couldn't connect to the page" (in Ubuntu 16.04 works). Is it a firewall problem?
I followed kaa installation guide (configuring zookeeper, mongodb etc)
Kaa's logs are empty (no errors, no warnings)...
I also tried compiling kaa 0.11.0 from source and this situation persists.
Greetigs,
kaa_newbie.
EDIT: It's a Zookeeper problem! Kaa works only on Zookeeper v3.4.8. If I install this version on Ubuntu 18.10, it works!

Qt creator doesn't launch in Linux Mint for QT 5.5.1

I used the offline installer to install QT 5.5.1 (32 bit) in Linux Mint Cinnamon 17.2 (32 bit) in VirtualBox. Install was OK. Then QT creator doesn't launch. QT 5.5.0 works OK. Any ideas anyone?
From the command line it says could not initialize GLX.

Why can't I launch R in server using vim R plugin?

My local computer platform is this:
Distributor ID: Debian
Description: Debian GNU/Linux 8.1 (jessie)
Release: 8.1
Codename: jessie
Where I have installed vim-r-plugin and it works well.
Now I have some project needs to work on server which turns out a platform of:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
In this server I can't launch R through \rf as I usually do on my local computer. My question is how to launch R from my server platform. Do I need to install vim-r-plugin again in the server Ubuntu platform?

Qt 4.8 compiling from ubuntu to windows

I have a simple app that I can compile on the desktop for Ubuntu 12.04, but not for Windows. I installed the MinGW toolchain, both from synaptic, and the QT 64-bit package from here.
I went to Tools-->Options-->Build, and manually added both the /usr/bin/i686-w64-mingw32-g++, as well as the g++.exe from the link above (in the bin folder) as MANUAL_1 and MANUAL_2.
When I go to create a custom target however I am unable to select either Manual toolchain and it reverts back the standard GCC x86_64 linux.
What am I doing wrong?
I doubted the g++.exe file would work since that is a windows binary, but why does it not select the system mingw binaries?
Few things you should check
Your gcc version number
Is your gcc path added to environmental variable?
I too found it very difficult to compile my MINGW Qt application in Windows, and after lot of research on net I found that qt4 works with gcc 4.4.0 MINGW. I downloaded qtcreator 2.1 from qt website and copy MINGW folder from qtcreator directory, copy that folder into my windows root directory then installed latest qt creator and qt4 sdk,
Add path of gcc
and finally qt creator compiles my code.
