I'm not sure whether I encountered are env/config related problem or
bugs,so I submit my installation process here for you to reference.
1.env description:
host os:Ubuntu 11.04(kernel 2.6.38-8-generic,x86_64)
libvirt:0.9.6
qemu:0.15.50
dtrace:sun D 1.6
systemtap:version 1.3/0.148 non-git sources
2.install systemtaped libvirt
(1)configure
./configure --prefix=/usr --with-dtrace
(2)make
--->error1:
dtrace: failed to compile script probes.d: line 2: invalid control
directive: #file:
solution:
delete lines begin with "#"
-->error2:
Invoking: ld -o probes.o -r probes.tmp.o /usr/lib/dtrace/drti.o
ld: i386 architecture of input file `probes.tmp.o' is incompatible
with i386:x86-64 output
dtrace: failed to link script probes.d: failed to link probes.o: ld
exited with status 1
????so the script incompatible for 64 system,is it a bug?
solution:
change "DTRACE=/usr/bin/dtrace" to "DTRACE=/usr/bin/dtrace -64"
-->error3:(with ./configure --prefix=/usr --enable-dtrace)
*** objects probes.o is not portable!
/usr/bin/ld: probes.o: relocation R_X86_64_32 against `.rodata' can
not be used when making a shared object; recompile with -fPIC
probes.o: could not read symbols: Bad value
tried:
(1)reconfig with
./configure --with-dtrace --disable-share
result:
compile success,but libvirt_probes.stp size is 0,stp script
can't be used
(2)add flags with -fPIC
result:
nothing changed,still the same error
(3)tried configure --with-pic
result:
nothing changed,still the same error
3.Here is my question:
(1)Is the system-enabled libvirt support 64bit system?
(2)Do you have suggestion about error3?
Sorry to bother you so many times,But I do think applying these patches
are important and useful for future debugging.Thank you for your time!
