compilers-1.0: default to gcc6

[ryandesign (Ryan Carsten Schmidt)]

The compilers 1.0 portgroup contains this line:

set compilers.gcc_default gcc5

Can this be changed to gcc6? gcc6 is the latest stable version of gcc at this time.

I switched to gcc6 for my ports and everything appears to work. However, I believe such a change should be brought up on the dev list to make sure that no one sees a problem with this.

Sounds fine to me.

I wonder if it would make sense to set this back to version 5 for 10.5/PPC (#51388). It might not help much though if default version is hardcoded at so many other places.

[dstrubbe (David Strubbe)]

Oh, I was not aware of that ticket. Yes we could certainly have the default set differently in that case. There are a lot of ports using the compilers portgroup although it is a minority of course, so it would help somewhat.

Replying to mojca@…:

What is the proper way to write an if-condition that would check if we have 10.5/PPC?

[ryandesign (Ryan Carsten Schmidt)]

If the issue is really specific to 10.5 PPC, you could write:

if {${os.platform} eq "darwin" && ${os.version} == 9 && ${os.arch} eq "powerpc"} {
    set compilers.gcc_default gcc5 
} else {
    set compilers.gcc_default gcc6 
}

Of course, I would rather fix #51388.
