[Jikesrvm-core] jconfigure

[Steve B. <Ste...@an...>]

Hi,

Before I go and submit a bug report ;-), I wanted to be sure I 
understood intentions correctly...

We currently use host and target config files.  These set a number of 
environment variables, some with the prefix HOST or TARGET (eg 
HOST_JAVA), others with no prefix (eg SED).

The current cvs head does not work for cross platform builds for me 
because I have different paths to sed on my host (redhat linux /bin/sed) 
and my target (ppc linux /usr/bin/sed).  Both are "correct" insofar as 
they are "standard" distros.  Of course I can "fix" this by adding 
sym-links on my machine, but that's not addressing the problem.

The "naive" fix is a bit ugly because it involves:

  . introducing HOST_SED (and presumably TARGET_SED)
    - changing the config files
    - changing jconfigure to use the appropriate one
  . changing the ordering of sourcing of HOST_CONFIG
    - currently the host config is sourced *after* host-specific scripts 
are generated (line 2252 in the current head).

These problems tend not to show up for most of you because you're not 
usually doing cross-platform builds.

Cheers,
