Hi all,

So far when building from source on Ubuntu I've always used the gcc-snapshot sources.  This is a Bad Habit (it's specifically disallowed by Debian for building actual packages), but was an effective workaround in the period before GCC 4.8 was released.

Anyway, now that 4.8 _has_ been released, the question is -- where to get the appropriate sources?  Ubuntu only has GCC 4.7.3 and earlier in its repositories, gcc-snapshot is now frozen (and probably is best to avoid if possible anyway).

It seems best to download sources from the Debian repos as they should be patched to work with Debian/Ubuntu, but I thought I'd ask in case anyone has any advice.

Thanks and best wishes,

     -- Joe

As multiarch support is in gcc-4.8 you can compile with the standard gcc sources and it'll work.

If you still want the debian patches for other reasons there's a gcc-4.8-source package in debian testing and apt-get source gcc-4.8 might work as well. But it seems those packages are not yet in ubuntu?

No, though I think there's a PPA.  I'll test with the regular GCC sources and report back.

I've built GDC with 4.8 on Mint 14 with no issues whatsoever.

It's building now, seems to be going OK ... will report back on results. :-)

What about for gdc master branch?  I guess the best thing to do is to svn checkout [*] from gcc trunk and build against that?

[* actually I'll probably use git-svn ...]

So, I downloaded and unzipped the gdc-4.8.1 sources from ftp.gnu.org, and then:

   ./setup-gcc.sh ../gcc-4.8.1/
   cd ..
   mkdir objdir
   cd objdir
   ../gcc-4.8.1/configure --enable-languages=d --disable-multilib
--enable-checking=release --prefix=/opt/gdc
   make -j2 2>&1 | tee build.log

... worked fine.  Perhaps time to update the Debian/Ubuntu instructions on the GDC wiki?  I'll happily do this myself if I can have access.

I still use gdc master with gcc 4.8.0. There are no changes yet which require a 4.9 snapshot.

What's the stability of gdc master like right now?  I remember Iain issuing a warning that things might get a bit shaken up after 4.8 was branched off.

Implementation-wise, yes (over 6000 line changes and counting, and we
are still on the same front-end version)...
Testsuite and stability-wise.  Nothing broken, infact there are more
fixes now than before!

So, my second full build of the day is underway ... :-)
