GCC 4.4.x -- What's missing?

[Alex Ionescu]

Hi,

As far as I am aware, GCC 4.4.x now works on Linux through RosBE 1.5 (minus some missing
patches for 64-bit hosts), and I've gotten it to work on SnowLeopard with some minor
hacks -- ie, all that's missing is for Colin, when he has time, to integrate the
little fixes for these non-standard hosts.

As for Windows, I think there is a fully working binary GCC 4.4.x/RosBE that builds trunk
just fine.

So what's missing for 4.4.x to become official, RosBE 1.5 to RTM, and for the 4.4.x
patch from BZ to be committed (The one that gets trunk building)?

Best regards,
Alex Ionescu

[Daniel Reimer]

Good question. I wonder, too. Problem could be that this patch forces 
ppl to use a new RosBE. At least last time i tried, it broke gcc 4.1.X 
build.

Forcing people to use a new RosBE is a *good* thing.

Sure it is. But explain this to the lazy bums out there :-P

Nah, honestly, I dont think theres a real reason except the big step 
having to update gcc.

I fully support moving forward too. If some lazy ppl don't want to  
use a newer RosBE, it's their own problem.

Yes, I've been fixing the 64-bit problems in RosBE 1.5, but got stuck at
GMP. Its auto-detection for the ABI value seems to be broken, because it
wrongly detects ABI=64 on a i386 Linux host for me.
Need to find a way to work around this problem before I can finish the new
RosBE version. Had no time for this over the holidays, maybe next week.

Yes, it's more or less done.
However, as we want to keep consistence, its Binutils version still needs to
be upgraded to the same snapshot version, which is going to be used by
RosBE-Unix.

Apart from this, it would be nice if KJK could add the code for his
suggested "rosbe-clean" target to our Makefile as soon as possible.
This way, the logic of RosBE's often criticized "clean" command would be
simplified and go into our Makefile. RosBE's "clean" would just call
"make
rosbe-clean" then and always clean the tree you expect (people with multiple
source trees know what I'm talking about).

As this modified "clean" command would also break compatibility with older
ReactOS revisions, I'd like to see the Makefile target being committed to
trunk before we release RosBE 1.5 (and break building with older RosBE
versions as well).
The "clean" scripts of the new RosBE version could already make use of this
target then.

I've prepared a 20091222 package for RosBE-Unix 1.5.
The source package usable for "RosBE-Builder.sh" and
"buildtoolchain.sh" has
just been uploaded to http://svn.reactos.org/RosBE-Sources/rosbe_1.5.

Daniel, if you're interested, try to use the buildtoolchain script under
MSYS to make a new Binutils build for RosBE-Windows using this source
package.

Colin

And don't forget that I've also updated the MPFR library required for
building to the final version 2.4.2. The new source package is available at
the same location.
See also my recent changes to the "buildtoolchain.sh" script.

and if I modify line 121: rs_mkdir_empty "$SYSHEADERDIR" to not delete 
my stuff it continues, but then hangs on gmp's configure, telling me 
that my gcc is not valid...

Know what? These GCC ********* should die in hell for making such a crap 
of a build process. RBuild ROCKS^2 compared to this!

There exist prebuilt packages of w32api and mingwrt, probably there is
no need to build them.

What does not work?

./configure CFLAGS="..." ABI=32
make
make check
make install

Another way is to copy GMP (and MPFR, and Binutils) into GCC top level
directory and allow GCC build scripts to deal with it.

Well, this would require us to build the entire RosBE-Unix toolchain for
32-bit as well (while all other RosBE-Unix versions built native 64-bit
binaries on 64-bit machines so far). It would also make RosBE more
CPU-dependent, a thing I'd like to avoid.
If you look into GMP's configure script, you'll also see that there are many
architectures which don't support a simple ABI=32 value. Even if these
architectures might currently not be interesting for us, they can certainly
be in the future.

GMP's ABI detection seems to be entirely based on the host CPU, but doesn't
consider the host OS. So if you're running a 32-bit OS on a 64-bit CPU, GMP
will detect ABI=64 and fail.
The only workaround I can currently think of would be checking `uname -m`
for "i*86" and setting ABI=32 in this case. Otherwise we'll let GMP
autodetect the ABI value.

But maybe someone else has better ideas.
I'd be surprised if I'm the first to notice that the common build procedure
"configure && make && make install" fails for such a simple
configuration as
having a 32-bit OS running on a 64-bit CPU.

Best regards,

Colin

[Alex Ionescu]

Colin, on OS X I built RosBE for 32-bits, and I think we should force that for the
moment...

But why don't you entrust configuration of GMP (and everything else)
to GCC's configure script?
