How to install QT(designer) 5.7.0 on CentOS-6.8

[getche]

I am trying to install QT 5.7.0 on CentOS-6.8.I have these files in QT 5.7.0

I open the CentOS terminal in QT folder and run the following command

./configure

Installation stops at this error

qt-everywhere-opensource-src-5.7.0/qtbase/configure: line 3494: g++: command not found Creating qmake... gmake: g++: Command not found gmake: *** [project.o] Error 127

After that i tried to install the following version of gcc-c++ shown in image

But they are giving me following error for gcc-c++-ppc64-linux-gnu-4.8.5-16.el7.1.aarch64.rpm

Package /root/Desktop/install/gcc-c++-ppc64-linux-gnu-4.8.5-16.el7.1.aarch64.rpm has incompatible architecture aarch64. Valid architectures are ['ia32e', 'x86_64', 'athlon', 'i686', 'i586', 'i486', 'i386', 'noarch'] ------------------------ gcc-c++-x86_64-linux-gnu-4.8.5-16.el7.1.x86_64 requires gcc-x86_64-linux-gnu = 4.8.5-16.el7.1 gcc-c++-x86_64-linux-gnu-4.8.5-16.el7.1.x86_64 requires libmpfr.so.4()(64bit) gcc-c++-x86_64-linux-gnu-4.8.5-16.el7.1.x86_64 requires libc.so.6(GLIBC_2.14)(64bit) gcc-c++-x86_64-linux-gnu-4.8.5-16.el7.1.x86_64 requires libmpc.so.3()(64bit) gcc-c++-x86_64-linux-gnu-4.8.5-16.el7.1.x86_64 requires libgmp.so.10()(64bit)

And for rest of gcc-c++ it is giving following error

Transaction error An unspecified transaction error has occurred More information is available in detail report gcc-c++-4.4.7-18.el6.x86_64 requires libstdc++ = 4.4.7-18.el6 gcc-c++-4.4.7-18.el6.x86_64 requires libstdc++-devel = 4.4.7-18.el6 gcc-c++-4.4.7-18.el6.x86_64 requires libmpfr.so.1()(64bit) gcc-c++-4.4.7-18.el6.x86_64 requires gcc = 4.4.7-18.el6

How i can resolve these issue and install successfully QT 5.7.0 on CentOS-6.8

@getche I'm not sure you can compile Qt 5.7 using GCC v4.7.
Do you really have to use such an old CentOS version?

Please tell me which Version of QT(Designer) will install on CentOS-6.8 ? And please provide me its download link ?

@getche Here some links which can be helpful:
https://doc.qt.io/qt-5/linux.html
https://doc.qt.io/archives/qt-5.7/linux.html

You first should solve your current problem: install the g++ compiler. I don't know why you get this error message, something to ask CentOS community. Did you try like this:

yum install gcc-c++

?

[getche]

@jsulm it is giving following error on running the command (please note my PC is offline and without internet)

#yum install gcc-c++

Well, then you will have to use some local storage containing the CentOS packages (like DVDs)...

[getche]

@jsulm, I can use USB for transferring the packages from internet. Kindly tell me which CentOS packages need to be downloaded and installed ?

I can't, because I don't know all the dependencies between the packages you need. This is not a Qt problem.
That's why the easiest way is to use a local package repository (like DVDs or what ever).

Kindly tell me installation steps QT-5.7
