GCC 4.1 RC1

GCC 4.1 RC1

[Mark Mitchell]

I will be spinning RC1 this morning, as previously announced.

I know that there are some outstanding patches in my email, which people
have requested for 4.1.  I'll review those before producing RC1, and
apply them to the 4.1 branch myself if appropriate; I'll still ask the
original submitters to apply to other branches.

Re: GCC 4.1 RC1

[Andreas Conz]

Hello to all and thank you for the good work,

I was trying to build GCC 4.1 RC1 on AIX 5.1 _32bit_.
The machine is not very fast and I made some mistakes in the beginning.

Now my build stops while configuring libstdc++-v3 :

--------------------------------8<--------------------------

I configured with
../configure --enable-prefix=XXX --enable-threads

is the problem described at the end of the build log supposed to happen?

In earlier versions I was able to work around this build problem with
the help of the --disable-multilib configure switch.

Have I misread the target specific build instructions or is this a build
problem?

	If you are building on a 32-bit only system, you need to configure
with --disable-aix64 so that it does not try to build 64-bit libraries.
GCC currently expects to be able to run executables in all multilib modes
when building natively.

(Someone please let me know if this is not correct)

I *think* you can go into kdb as root and type "stat" and the second  
line will tell you if you have a cpu capable of 64 bit operations.

You can build 64 bit libraries in 32 bit mode -- it depends upon your  
processor type.  kdb will tell you that.  Its probably somewhere in  
ODM as well.

HTH,
Perry

	You are answering a different question.  AIX supports building
64-bit executables on 32-bit systems.  It does not depend on the
processor. 

	The question is about bootstrapping GCC.  GCC bootstrap wants to
run 64-bit executables during its configuration process.  This is
orthogonal to whether GCC or AIX can compile 64-bit executables on a
32-bit system.

       The bootstrap wants to run executables corresponding to each
multilib, so one currently needs to perform the bootstrap on a system
capable of running in all modes or restrict some of the multilib modes.

Thanks

I was mostly trying to give Andreas a way to determine what type of  
system he has (via kdb).

could somebody include this into the build documentation?

now there is a problem building the POWER part of libstdc++ :

I am building on an 32bit PowerPC (43P-150).
Should I file an bugreport?
