I can't install gcc 9

[Dorian ROSSE]

I was think It is better to use laster gcc than the gcc GitHub repositorie mirror from git gcc !

Laster command line was the following :

../gcc-9.1.0/configure --enable-languages=c,c++,go && make && make install

Now I install isl dependencies !

Then I launch again ‘configure’ command line 😊

You're running configure twice, with different options. Why?

Why is it ../gcc-9.1.0/configure the first time, and ../gcc/configure
the second time?
