Hi Steve, I can definitely understand the want for a newer compiler, but here's a question for you and the Scale team-- what requires the newer compiler? The userspace tools or the kernel module? I ask because as we all know it can be quite easy to install a modern build chain even on an older operating system or even build binaries on a new operating system that will run on an older operating system.
Surely the userspace components could be built with a newer compiler and the gplbin layer would just be built with whatever compiler is present on the system. I suspect there's more complexity and subtlety to the issue but I thought I'd at least ask. I know SLES12 has been out for a while now but that doesn't mean we can just pick up and move to a new OS without some difficulty, especially if the older OS is working just fine :) -Aaron On 12/19/17 8:18 AM, Steve Duersch wrote: > As Mike Taylor pointed out in a previous post this was an incorrect > statement. > You can be at 4.2.x (ie 4.2.0, 4.2.1, 4.2.2, or 4.2.3) and still do a > rolling upgrade. > The minReleaseLevel is not pertinent to a rolling upgrade.
