[mxe-octave:dev] default-octave on hydra site

[Tatsuro MATSUOKA]

If mxe-octave is configured with --enable-octave=default, mxe-octave is set to 
build default branched source.
If one did not make tar ball by oneself, the mxe-octave will download default 
branch source from the hydra site

http://hydra.nixos.org/job/gnu/octave-default/tarball/latest/download


However, this tar ball has two demerits:

1. It is not the latest. (Some delays always happen.)
2. Contents of the file HD-ID is "unknown" and ChangeLog is empty so that 
   one cannot know to which commit is applied to the source tree.

Of course, as is written in the wiki about mxe build,

http://wiki.octave.org/Windows_Installer#Step_2:_To_build_your_first_Octave-for_Windows_development_version:

It is better to build octave on Unix family (linux etcs.) and make tar ball by 
make dist.

The tar ball using this procedure has not unknown HD-ID and not empty ChangeLog.


Perhaps the procedure that the mxe-octave downloads tar ball 
from hydra site when octave-x.x.x+.tar.gz does not exist in the pkg directory
is considered to be users' convenient.
However, demerit is not so small, I think.

In my opinion, it is better that use of tarball from hydra site will be 
optional.
