how to run?

[Adam Goode]

Hi,

I maintain mlton in Fedora, which I would need to bootstrap to get 
working on s390x. I have Hercules, but I don't know how to actually run 
Fedora on it. The page
http://fedoraproject.org/wiki/Architectures/s390x doesn't have any info.

Could the wiki be updated to point to a root image or other mechanism 
for install?

Thanks,

Adam

Hi Adam,

We don't have an installable tree or root images yet, we're still in the 
process
of rebuilding all F-11 packages on s390x. The latest build attempt of 
mlton failed
because the htmldoc package doesn't exist yet and the bootstrap flag 
wasn't set:
http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=56256

As hercules is too slow to build packages (in my opinion), you'd better 
wait for
the htmldoc package and then use the koji builders to bootstrap your 
package:

SECONDARY_CONFIG=" -c ~/.koji/s390-config " make build

Thanks, Karsten.

As mlton is actually a compiler for SML and has never been built on
s390x to my knowledge, I need to set up an emulated environment (or get
access to a real environment) and do some cross compiling first to get
it bootstrapped. There is even a tiny bit of assembly that might be needed.

Also, do you happen to know if the s390x target supports ieee 754
floating point? That is one of the main issues I have had with getting
mlton working on ARM.

Thanks,

Adam

IBM System Z has IEEE 754 floating point support starting with the z9 
and with the new z10 those are integrated into the processor cores 
properly. So that shouldn't be an issue.

Hope that helps,
