[q-lang-users] gentoo ebuild

[Á. C. C. <alv...@gm...>]

Hello!

I have good news about the Q ebuild for gentoo.

I updated the llvm ebuild with all requirements for  Q and last 2.3
version, taking care of compiler version issues with it.
I managed to compile and get llvm running with not many problems, just:

1) The PIC issue: I had to apply the patch to llvm and compile it with
"make CXXFLAGS=-fPIC", otherwise the patch didn't do all its work

I get this nice code-quality "warning: dereferencing type-punned
pointer will break strict-aliasing rules"

2) I had to add the "limits.h" include in runtime.cc, otherwise it
didn't find LONG_MAX. Do you want to add this or should I prepare a
patch for gentoo?


I'll make the ebuild with all this information. Any
compilation/configure flags that I should especially care of?


Regards,

Álvaro

You're talking about Pure, right? Q doesn't need/use LLVM.

There's also a configure option --enable-pic to enable that, and yes, 
it's needed in addition to applying the patch (otherwise LLVM won't be 
built with -fPIC anyway). Pure's INSTALL file has more information on 64 
bit issues.

Thanks for reporting, fixed in r438.

See the INSTALL file for detailed instructions. I'd suggest 
--enable-release.

BTW, I'm cc'ing pur...@sf... now, could you please redirect 
your future posts on Pure as well? The subscription page is at 
https://lists.sourceforge.net/lists/listinfo/pure-lang-users

Cheers,
Albert

Thanks, I'll do it from now on. I'll post there links to both ebuilds.
