Rif: Re: Working with Cygwin

[silverio.di at qem.it]

peraps depends by extraction phase from bz2 files,
I've used the WinZip.exe program because I don't know the correct way to
do same thing with GNU tools....

I've used bunzip2 & tar in this way:

bunzip2 xxxx.bz2
tar -xf xxxx.tar (result from bunzip2 operation)

where xxxx.bz2 are oarcorp prebuild binaries for m68K. 386, SH
microprocessors
and they are located onto root directory

If I mistake the arguments on bunzip or tar please write me the right
options

bunzip2 [options] xxxx.bz2
tar [options] xxxx.tar  (result from bunzip2 operation)

thank you very much :)

This works for me.  I just tried i386-rtems. My PATH is set in bash
style of

export PATH=/opt/rtems/bin:$PATH

Add a -v on the gcc command and look at precisely what is invoked for
ld.
I suspect that /OPT/RTEMS != /opt/rtems/ which is what the tools are
configured for.
