Also, the 4.1.x series of GCC can be a little bit wonky (technical term) when compiling system tools. Otherwise, since the problem is in assembler, I would suspect the binutils.<br>-Gedare<br><br><div class="gmail_quote">

What is your PATH when building gcc? I have a hunch that<br>
you forgot to put the RTEMS cross-assembler at the head<br>
of your PATH. It is likely using the native as which won't<br>
work for powerpc code. :)<br>

Actually, it should be the native GCC since I'm building the<br>
cross-compiler.<br>

I didn't notice this was on a native gcc. Still probably<br>
worth it to repeat the command by hand with a -v and see<br>
if what as it is using. Worse case, you might have an old<br>

It has long been considered a security mistake. I think this<br>
dates back to the earliest UNIX days. :)<div><div></div><div class="h5"><br>

/opt/rtems4.11/bin:.:/usr/local/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/l<br>
ocal/sbin:/usr/X11R6/bin<br>
<br>
<br>
I removed the . and then the build got past the problem (won't know if<br>
it worked until it finishes building).<br>
<br>
<br>
I consider the . in my PATH as a security error since it allows a<br>
someone to drop an executable (like vi) in a source directory and when<br>
the victim enters the command "vi foo.c" the victim runs the vi<br>
executable from the current directory instead of from /usr/bin or<br>
wherever it should be.<br>
<br>
<br>
I'm not sure why having the . in my path caused a problem but I don't<br>
mind removing it so I guess the problem is solved.<br>
