First time help with gcc compile and install.

[Chris Kirsten <krakkeroe at gmail dot com>]

Hi,


I am completely new to gcc.  I converted my Lenovo G580, i3 4-Core x86_64 laptop 
from Windows 8 to Linux Mageia 5, now 6, the latest upgrade.  I am busy with a 
web developing course at Udemy, but cannot view their course video's.

Gnash requires a C++ compiler which led me here.  I carefully read and followed 
the GCC Manual.  My Gcc-object directory was made next to gcc-7.2.0 from the 
start.  I used the software as it was downloaded.  The listings are copied from 
the terminal window, no editing.  I did edit the Path for C++ and tried the same 
for g++ and gnat, but in all cases the result, before and after, showed as under 
*Gnash result.*  I did this in .bash_profile.

Machine; Lenovo G580 i3 4-Core x86-64.
OS; Mageia 6.  After Windows 8 stripped, Killdisk one pass on Hard disc.

I later got the same diagnostics in the gcc config.log file.

_*Questions;*_

I understand the situation around compile time errors.

1.  Can I safely ignore the errors?  It seems the Stop in the Make install 
result is fatal.

2.  Any ideas on what I may have left out or did wrong?

3.  How do I address the g++ issue correctly?  Tried Gnash again.  Same thing.

Please let me know of any further information needed.  I kept the listings as 
short as possible.


Thank you,


Chris.
