Patch from Ralf Corsepius <corsepiu@…>:

  1. Rtems contains some perl scripts that use hard-coded paths to /usr/bin/perl or /usr/local/bin/perl I have already fixed these problems by adding some checks to configure.in. While doing this, I also cleaned up some more autoconf related problems for generating shell scripts. This patch might seem a bit scary to you, but I am quite confident it won't break something (I've been testing it for almost a week now, however it might introduce typos for a limited number configurations I don't have access to - But it shouldn't be a problem for you to test them :-).

I expect to get this finished tonight, hence you will very likely
have the patch when you get up tomorrow.

Changes:

  • Check for PERL and disable all PERL scripts if perl wasn't found.
  • Generate all KSHELL-scripts with autoconf instead of make-script
  • Automatic dependency handling for autoconf generated KSHELL or PERL scripts (make/rtems.cfg)

Notes:

  • this patch contains new files and deletes some other files.
  • The patch is relative to rtems-4.0.0-beta4 with my previous rtems-rc-981014-1.diff patch applied.

Testing:

I tested it with sh-rtems and posix under linux. Now all targets
which are touched by this patch and which are not used while building
for sh-rtems and posix still need to be tested. AFAIS, only the
sparc/erc32 BSP should be affected by this criterion. And if you
like to, you should also consider testing it on a Cygwin32 and a
Solaris host for one arbitrary BSP.
