i was making the tool-chains by following the instructions in the lastest<br>
Book ?Cross-Compiled Linux From Scratch - Version GIT-20110213-PowerPC?<br>
found in the SVN (<a href="http://cross-lfs.org/files/BOOK/" target="_blank">http://cross-lfs.org/files/BOOK/</a>)<br>
Eevey thing is OK when i make the tool chain for powerpc ,and finally i got<br>
it .<br>
After that , I Firstly use the powerpc-unknown-linux-gnu-gcc to make a<br>
helloworld , the program can run correctly on the target machine.<br>
but when i use the powerpc-unknow-linux-gun-g++ to compile the same program<br>
( syntax is right, just printf("hello world") or cout << helloworld )<br>
,it throws the error : " illegal instruction " on the target machine ?<br>
I don't know why ????can someone help me ?<br>

Hello!<br>
<br>
Modifiying Makefile as previously explained only fixes the "Operation not<br>
permitted" (ignored) errors. However, the 'make MULTI=1 install' still<br>
doesn't create any symlink automatically, so you have to create them by hand<br>
as explained on the CLFS book. I confused that because it was the behaviour<br>
I was expecting, just as busybox does. But I just have read "MULTI"<br>
documentation file, and it explains this is the proper way to do it. So, the<br>
book it's ok.<br>
<br>
Best regards,<br>

What is your target machine?<br>
<br>
PPC c++ created binaries make use of the 'lwsync' instruction. That<br>
instruction works fine on 'normal' powerpc but throws an illegal exception<br>
when run on the booke type of cores. If your target is a booke/E500<br>
core, it is possibly the problem.<br>
