Problem with QEMU

Problem with QEMU

[Romulo Rosa]

Hi,

I'm trying to compile QEMU on Ubuntu 12:04 and'm having the following
problem:

LINK  x86_64-softmmu/qemu-system-x86_64
/usr/bin/ld:
/home/xerifao/ovs_dpdk/dpdk-1.5.1r1/x86_64-default-linuxapp-gcc/lib/librte_eal.a(eal.o):
relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making
a shared object; recompile with -fPIC
/home/xerifao/ovs_dpdk/dpdk-1.5.1r1/x86_64-default-linuxapp-gcc/lib/librte_eal.a:
could not read symbols: Bad value

collect2: ld returned 1 exit status


The fPIC flag is setted on my Makefile:

pixman/Makefile: $(SRC_PATH)/pixman/configure
         (cd pixman; CFLAGS="$(CFLAGS) -fPIC $(extra_cflags)
$(extra_ldflags)" $(SRC_PATH)/pixman/configure $(AUTOCONF_HOST)
--disable-gtk --disable-shared --enable-static)


Anyone know how to help me?

Thanks!

You need to compile DPDK with -fPIC option..

Thanks for the feedback. I compiled the DPDK with the -fPIC option. Is
there any specific location in the Makefile DPDK where should I put the
-fPIC option?

You can use EXTRA_CFLAGS=-fPIC on the command line.

Re: Problem with QEMU

[Romulo Rosa]

Hello guys, thanks for the help. Yesterday I could compile with-fPIC
however'm already trying to solve another problem in compiling QEMU. I had
the same problem compiling ovs. Jyotiswarup Raiturkar helped me with OVS
and I'm trying to adapt the solution to this case. If you already know how
to appreciate the help again.

/dpdk-1.5.1r1/x86_64-default-linuxapp-gcc/lib/librte_eal.a(eal_common_nonpci_devs.o):(.data.rel+0x8):
undefined reference to `rte_pmd_ring_init'
collect2: ld returned 1 exit status
make[1]: ** [qemu-system-x86_64] Erro 1
make: ** [subdir-x86_64-softmmu] Erro 2

Just to record how I solved the problem for those who might have the same
problem. Then run the command / configure - enable-kvm - dpdkdir = / path /
to / dpdk - target-list = x86_64-softmmu
