Optionally use Clang compiler

Continuing discussion from NodeOS/NodeOS#267 (comment)

Starting @piranna and @luii

[joshgarde]

Already using clang here on OS X. Works just fine.

Already using clang here on OS X. Works just fine.

Are you using clang to generate the cross-compiler, or have you replaced gcc for clang IN the compiler? If so, have you been able to compile a working kernel?

[joshgarde]

Mac OS X aliases gcc and g++ over to clang by default. Only tried the cross-compiler and the other two projects I've ported over so far with good results. I haven't tried compiling the kernel yet (which I assume is part of nodeos-barebones) because I'm still caught up with travis support, but I'll try it later.

[piranna]

Yes, it is, just wanted to be sure :-) Anyway it's a huge effort, specially the Travis part! :-D

[piranna]

If you are in th mood, go for it ;-) Have you tried to compile Node.js with
gcc?

Update: It seems that nodejs, when compiling for OS X, expects clang
instead of GCC so clang support for the toolchain might be my next project.

Node.js throws clang specific arguments at CXX and CC when trying to compile for OS X so GCC isn't really an option unless I can override those args or just get GCC to ignore them. I can compile for Linux on OS X, which works for a while before I get an internal compiler error.

[joshgarde]

The compiler error, seems to be resulting from an invalid file path though, but I'm not really sure where the path is coming from.

I believe the problem is with the last two commands. Take notice of the /Volumes/NodeOS-OSX/nodejs/deps/node/out/Release/.deps//Volumes/NodeOS-OSX/nodejs/deps/node/out/Release/obj.target/cares/deps/cares/src/ares__close_sockets.o.d.raw path. It's combined two paths together for some reason. I'm really not sure if it's a problem with Node.js' makefile or if it's a problem with the nodejs package on here.

Node.js throws clang specific arguments at CXX and CC when trying to

Maybe is it time to create a pull-request to allow to compile Node.js on
OSX using gcc...? ;-)

I can compile for Linux instead on OS X, which works for a while before I
get an internal compiler error.

That's a shame, because that's just what we need for NodeOS, to compile it
for Linux... :-( The prebuild ones could be used, but it should compile too
as fallback... :-/

[piranna]

Can you post the full backtrace?

Not a lot of help, but the rest of the compile works fine. Not a memory issue either (Monitoring it the entire build). I can only assume it's the broken file path.

It could be, but I've only get internal errors on cc1 due to out of memory
errors... How much ram do you have? Could you be able to compile it in a
fleshly rebooted system?

[joshgarde]

8GB of RAM & around 4-5GB free upon fresh reboot.

I'm compiling node.js on my case sensitive file system. It's probably just the broken file path.
