This PR is inspired by #10388 when I try to compile the node v6.x with gcc 4.8.0 :(. I check the prerequisites at BUILDING.md and It tell me that gcc version at least is 4.8.0 which is actually out of date (Aslo a typo about or).

bnoordhuis · 2017-03-14T09:58:54Z

First commit LGTM, thanks. The , or is not a typo though, it's to signal that you need either g++ x.y.z OR clang++ x.y.

detailyang · 2017-03-14T12:17:51Z

Hello.
@bnoordhuis gotcha! Many Thanks :D

The latest version of 4.8 available for 12.04 is 4.8.4. It is not able to build V8 from version 5.7 and does not satisfy the requirements to build Node.js. Refs: nodejs/node#11840 Refs: nodejs/v8#5

LGTM, but I see some discussion about requiring 4.9 in other issues.

bnoordhuis · 2017-03-14T14:34:01Z

We'll probably drop g++ 4.8 for node 8.0. Bumping the baseline from 4.8.0 to 4.8.5 for <= v7.x is a good idea, though.

bnoordhuis

LGTM. Can you mention in the commit log that the bump is because of compiler bugs in g++ < 4.8.5?

detailyang · 2017-03-14T14:50:34Z

No Problem. I will do rebase these commits to one commit after cloning this huge repo slowly because of Chinese GFW :(

bnoordhuis · 2017-03-14T15:11:31Z

Oh, I suppose that whoever merges this can amend the commit log.

bumping the baseline from gcc 4.8.0 to gcc 4.8.5 because of compiler bugs in g++ < 4.8.5.

…ch-1

detailyang · 2017-03-14T16:22:27Z

It looks like cannot rebase the PR which have already issued without git push --force (sorry, my fault). Maybe some people can squashing these commits when merging and mention what @bnoordhuis said

bumping the baseline from gcc 4.8.0 to gcc 4.8.5 because of compiler bugs in g++ < 4.8.5.

Many Thanks :D

detailyang · 2017-03-15T03:02:05Z

BTW, 4.8.5 is a good interim version IMO since the centos:7 is using the 4.8.0 as the system default version and other system like fedora:latest 、debian:lastest and ubuntu:latest is at least 4.9.0.

is this also accurate for v6.x?

Based on:

I'd say so.

4.8.2 works fine on my old Linux box. Why do we have to make it 5? #13462

@bnoordhuis I note that this never happened, do you know if it needs to (i.e. will 4.8.5 be okay for the lifetime of v8.x)?

bnoordhuis · 2017-06-05T08:49:51Z

@gibfahn C++11 support is not 100% functional in 4.8.x. Updating the requirements is still a good idea, IMO; we don't want to be hampered by compiler bugs. I'll file a pull request.

The 4.8.x releases don't fully support C++11. Update the prerequisites for node.js 8 so that we won't have to work around compiler bugs in the future. To be decided if we should also update the minimum clang version. I believe clang 3.4.2 properly supports C++11 but am not 100% sure. Refs: nodejs#11840
