installing gcc 4.3 on ubuntu 15.10

james2408 · 05-04-2016, 02:12 AM

first I removed my current version of gcc i.e gcc 5.2
then now I'm trying to install gcc 4.3, its showing this error
please help

Package gcc-4.3 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

Why are you trying to install an old version of gcc?

The reason it is not available is because it is, err, not available for Ubuntu 15.10.

It seems as though you CAN install gcc 4.9 though:

Best regards,

actually the installation is compatible with gcc-4.3 only and I dont want to use ubuntu 8.10 because further commands are not executing in ubuntu 8.10. So, please suggest me which ubuntu version would allow me to install gcc-4.3.

Thank you

I don't understand. Are you using Ubuntu 15.10 or 8.10? I hope it is not the latter because it is severely outdated.

Although there are caveats, you can have multiple versions of gcc on the same computer. Far better to do this than to remove the default gcc on a system - it is a very important component of any system.

However, if you just want to set up a mini not very up-to-date system to run one program, and can live with the fact that it will be full of security holes, then fair enough. You can find out which versions of the major software each Ubuntu version supports here: http://distrowatch.com/table.php?distribution=ubuntu

The default compilers for Ubuntu 15.10 are :
gcc-4.7, gcc-4.8, gcc-4.9, gcc-5
... where gcc-5 = gcc-5.2.1 is the system compiler.

There are some extra compilers available : gcc-3.4/g++-3.4 , gcc-4.1/g++-4.1 .

? Which version of Ubuntu 15.10 ?
This command will reply with arch : $ uname -m

? Which software is it you want build ?
( Older information about gcc-4.3 may not be valid for Ubuntu 15.10 ).
