[Qemu-devel] [Bug 1193628] Re: Undefined References

[jean-christophe manciot]

@Peter Maydell (pmaydell): you're right, but in the meantime, I needed
to find another solution.

@Michael Tokarev (mjt+launchpad-tls): Thanks a lot for your answer, it
helped me pass this hindrance... to find 2 other obstacles.

Regarding the first one: I patched the two files as recommended (and added 
comments to the third one). There's a confusing thing though: the displayed 
"configure" file is very different from the one which is distributed with the 
1.1.0 release, so the line numbers are not correct.
The patch needs to be done from line #2569, instead of #2673.

Anyway, I was able to continue making qemu until this error: 
"  LINK  lm32-softmmu/qemu-system-lm32
/usr/bin/ld: milkymist-tmu2.o: undefined reference to symbol 'XFree'
/usr/bin/ld: note: 'XFree' is defined in DSO 
/usr/lib/i386-linux-gnu/libX11.so.6 so try adding it to the linker command line
/usr/lib/i386-linux-gnu/libX11.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make[1]: *** [qemu-system-lm32] Error 1
make: *** [subdir-lm32-softmmu] Error 2"

I had to apply another patch to "configure" from here:
http://permalink.gmane.org/gmane.comp.emulators.qemu/193007

Then I ran into another issue:
"  CC    cris-linux-user/signal.o
/home/actionmystique/Downloads/qemu-1.1.0/linux-user/signal.c:3479:24: error: 
field ‘info’ has incomplete type
make[1]: *** [signal.o] Error 1
make: *** [subdir-cris-linux-user] Error 2"

This was solved with a last patch on "linux-user/signal.c" from:
http://git.qemu.org/?p=qemu.git;a=commit;h=02d2bd5d57812154cfb978bc2098cf49d551583d

And now I'm finally able to compile, link and install qemu-1.1.0 on
Ubuntu 13.04 without any error! :)

N.B: I have attached the four files as tar.gz for further reference; you
may want to include these new files into qemu 1.1.0.

** Attachment added: "configure - def-helper.h - exec-all.h - 
linux-user/signal.c"

Title:
  Undefined References

Status in QEMU:
  New

Bug description:
  I've been able to make qemu on ubuntu 13.04 for all last releases:
  1.4.0 -> 1.5.0

  Unfortunately, when I launch one of them with a Cisco ASA, it crashes inside 
GNS3 (latest release) for Ubuntu.
  The top GNS3 developer told me they experienced similar results and advised 
me to use qemu 1.1.0.

  The problem is that I cannot link that version. I always have these errors:
   
  "LINK  qemu-ga
  qemu-timer.o: In function `dynticks_rearm_timer':
  /home/actionmystique/Downloads/qemu-1.1.0/qemu-timer.c:538: undefined 
reference to `timer_gettime'
  /home/actionmystique/Downloads/qemu-1.1.0/qemu-timer.c:551: undefined 
reference to `timer_settime'
  qemu-timer.o: In function `dynticks_stop_timer':
  /home/actionmystique/Downloads/qemu-1.1.0/qemu-timer.c:524: undefined

reference to `timer_create'
  collect2: error: ld returned 1 exit status
  make: *** [qemu-ga] Error 1"

  The man pages say we need to link with '-lrt' option, but I could not find it 
in the Makefile.
  I do not know how to correct this issue.
