Hello All<br>
I am in process of learning kgdb and facing some problem with
gdbserver. I am not able to "configure and make" the gdbserver . Sorry fot the long mail.<br>
<pre>Did anyone tried to compile the KGDB with this powerpc-eabi ?? Please help me in solving this.</pre>
Setup datails are below..<br>
Host: x86, RHEL-2.6.9-34.EL<br>
Target Linux- <a href="http://2.6.16.2/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">2.6.16.2</a><br>
Target Processor: AMCC440SPe<br>
The kgdb version : linux-2.6.15.5-kgdb-2.4 <br>
GDB version gdb-6.4-kgdb-2.4.tar.bz2<br>
CrossCompiler - powerpc-eabi<br>
<br>
<span style="font-family: monospace;"></span>I applied the patch to the
kernel and cross compiled it.(modified to solve the compilation
errors as is not supported readymade).<br>
<br>
I used the steps given in "<a href="http://www.kegel.com/linux/gdbserver.txt" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.kegel.com/linux/gdbserver.txt</a> " to build the gdb.
<br>
<br>
I compiled the gdb for host with following commands<br>
<br>
#ls<br>
gdb-6.4 gdb-6.4-kgdb-2.4.tar.bz2<br>
<pre>#mkdir ppc440<br>#cd ppc440<br>#/bin/sh ../gdb-6.4/configure --target=powerpc-eabi --with-solib-absolute-prefix=/opt/ppc440<br>#make<br>#cd ..<br><br>For gdbserver, if i give the "--target=powerpc-eabi" to "configure" script, it says the target
<br>is not supported by gdbserver and if i give "--target=powerpc-linux", it doesnt show any error <br>but its output doesn't look fine . But when i do make. i get many errors saying many files <br>are not found. (Adding few required header files didnt help.)
<br><br>I cross compiled the gdbserver with following commands:<br><br>[root@localhost gdb]# mkdir cross-ppc440<br>[root@localhost gdb]# ls<br>cross-ppc440 gdb-6.4 gdb-6.4-kgdb-2.4.tar.bz2 ppc440<br>[root@localhost<br>
