<NickHu> alj: In my experience nixos on armv7l was just too painful
<NickHu> To build the base system (with no extra packages) it wanted to build LLVM which not only took 2 days but kept failing in the test phase
<gchristensen> I agree
<gchristensen> this is part of why we don't support armv7l
<clever> i remember llvm taking a full 48 hours
<sphalerite> gchristensen: I thought it's more the other way round, that it's *because* we don't support armv7l :p
<gchristensen> as release manager can you imagine trying to get a release out and being blocked because llvm failed in hour 44 of a 48 hour build?
<sphalerite> well, aarch64 didn't block the release in 18.09 and was supported
<gchristensen> right
<gchristensen> we also have like 300 cores of aarch64
<gchristensen> to put it another way, we'd need a large number of faster-than-a-pi armv7l cores
<sphalerite> yeah
<sphalerite> and fast storage
<gchristensen> yeah
<gchristensen> though if someone wants to bequith us with a cluster of like 1,000 pi's ...
<sphalerite> then we still have a difficult software problem to solve :D
<gchristensen> yeah...
<gchristensen> (bummer -- the compute module has only 1g ram)
<sphalerite> I really want one of those dev systems that you(?) recently linked a presentation about
<sphalerite> which don't exist yet
<gchristensen> the one with like a thousand Pi's to simulate distributed HPC?
<gchristensen> ah, not me :)
<gchristensen> nice!
<sphalerite> huh, I can't find it in the logs
<sphalerite> I must have found it somewhere other than IRC

<alj[m]> so in essence I need to find some hundred arm7l cores somewhere? oh man haha
<alj[m]> or we need better crosscompile support?
<alj[m]> could we actually use x86 to cross-compile llvm (for example) ?
zupo has quit [Ping timeout: 246 seconds]
<sphalerite> alj[m]: yes, you can cross-compile that stuff. nix build nixpkgs.pkgsCross.armv7l-hf-multiplatform.llvm for example. Unfortunately, cross-compiled packages aren't equivalent to natively-built ones and they're hard to mix.
zupo has joined #nixos-aarch64
<alj[m]> well that kinda defeats cross-compiling anyway...
<alj[m]> I'll keep my eyes open for an old raspi Bitcoin Mine or something...

<lopsided98> My ODROID-XU4 builds everything I need for my armv6l and armv7l machines in about 2 days
<thefloweringash> I can tell you don't use chromium ;-)
<lopsided98> yeah, my machines are all headless
