Description Malo Deniélou 2012-04-02 15:27:36 CEST

Description of problem:
When compiling a program with module eventch, I get the following error:
Error: Error on dynamically loaded library: /usr/lib/ocaml/eventchn/dlleventchn_stubs.so: /usr/lib/ocaml/eventchn/dlleventchn_stubs.so: undefined symbol: xc_evtchn_unbind

When compiling a program with module xl, I get the following error:
Error: Error on dynamically loaded library: /usr/lib/ocaml/xl/dllxl_stubs.so: /usr/lib/ocaml/xl/dllxl_stubs.so: undefined symbol: libxl_device_disk_del


Version-Release number of selected component (if applicable):
ocaml-xen-0.8.0-1

How reproducible:
Everytime

Steps to Reproduce:
1. Install ocaml-xen
2. create a simple test file containing Â«print_string "hello"Â»
3. compile it with 
ocamlfind ocamlc -o test -thread -package eventch -linkpkg -g test.ml
4. It gives the error.

The other error comes when using the xl module.

Hi,

This bug was filed against cauldron, but we do not have cauldron at the moment.

Please report whether this bug is still valid for Mageia 2.

Thanks :)

Cheers,
marja

Comment 3 AL13N 2013-01-02 20:00:57 CET

is this cauldron or mga2 or ?

what happens when you do "ldd /usr/lib/ocaml/xl/dllxl_stubs.so" ?

could it be possible for you to rebuild ocaml-xen?

Comment 4 AL13N 2013-01-08 23:04:54 CET

i just submitted xen-4.2.1-1.mga3, it might be interesting to retry

do know that packages are named differently now:

xl => xenlight
eventch => xeneventch

Comment 5 Malo Deniélou 2013-01-08 23:12:33 CET

Thanks, I will have a look.

Comment 6 AL13N 2013-03-02 08:43:34 CET

is it fixed now? can we close this?

Comment 7 Malo Deniélou 2013-03-03 12:23:25 CET

Not fixed yet, I still get these undefined symbols errors.

Comment 8 AL13N 2013-03-03 13:24:51 CET

did you use "ocamlfind ocamlc -o test -thread -package xeneventch -linkpkg -g test.ml" instead of "eventch" ?

and "xenlight" instead of "xl"?

Comment 9 Malo Deniélou 2013-03-03 21:52:27 CET

Yes, there are actually several different errors now.

First pb: /usr/lib64/ocaml/xenlight/META should refer to xenlight.cm{,x}a

Second pb : for xenctrl, when I do 
$ ocamlobjinfo /usr/lib64/ocaml/xenctrl/xenctrl.cmxa

I get: 
Extra C object files: -lxenctrl_stubs /home/iurt/rpmbuild/BUILD/xen-4.2.1/tools/ocaml/libs/xc/../../../../tools/libxc/libxenctrl.so /home/iurt/rpmbuild/BUILD/xen-4.2.1/tools/ocaml/libs/xc/../../../../tools/libxc/libxenguest.so

There is a path problem there during the production of the library.

Third pb: I get a similar:
Extra C object files: -lxeneventchn_stubs /home/iurt/rpmbuild/BUILD/xen-4.2.1/tools/ocaml/libs/eventchn/../../../../tools/libxc/libxenctrl.so

when i look at ocamlobjinfo /usr/lib64/ocaml/xeneventchn/xeneventchn.cmxa

No pb with ocaml modules: xenmmap, xenstore, xenbus though :-)

Hope that helps.

hmm, i know next to nothing about ocaml(i don't even know what it is or does), so you'll have to help me a bit in figuring this out...

1. are you saying that this should just be changed? just one word?

2. does this mean it's libraries that are badly linked? or something similar.? what would you expect?

3. same?

Comment 11 AL13N 2013-03-10 09:02:25 CET

i found in your ocaml wiki:

ocaml-xen should be split in ocaml-xen and ocaml-xen-devel, (2013-03-04)

    missing Requires: xen-devel 


what kind of filenames should be in -devel and which in regular package? should some files be deleted? ie: the .a files?

Comment 12 AL13N 2013-04-04 08:23:22 CEST

i split up and fixed Xen with the help of upstream...

i submitted it. can you retest?

Comment 13 Malo Deniélou 2013-04-05 20:53:09 CEST

Works now. Thanks.
