Dear Rooters,
I'm sorry if this mail should have been sent to the cint
newsgroup.
I think that it covers some of the basic ROOT enviroment, that's whi I
write to you!
MY PROBLEM:
I've installed first ROOT v 3.01/06 and then ROOT v 3.02/07.
With both I got problems with my 2 link
library libLastra.so and libTrack.so.
which I had previously compiled using ROOT v 3.00/06.
ROOT v 3.01/06 issued the following:
------

The internal data structures have been changed.
Please recompile the setup file which contains
the definition "G__cpp_setupLastraDict()"
using CINT version 5.15.07, July 7 2001.

dlopen error:
/lxmacro_home2/chiarusi/zonalavoro_root/./mylib/libLastra.so: undefined
symbol: Execute__7TObjectPCcT1
Load Error: Failed to load Dynamic link library
/lxmacro_home2/chiarusi/zonalavoro_root/./mylib/libLastra.so
*** Interpreter error recovered ***
------
IT WAS CLEAR I HAD TO RECOMPILE MY TWO LIBRARIES!!!!!!
So I cd first to my Lastra directory, containing the following files
------------
libCint.so._3.00* libCint.so._3.01* libCint.so._3.02*
libCint.so@
Lastra.cxx Lastra.h LastraLinkDef.h
Makefile_lastra
------------
where
---
libCint.so._3.00* libCint.so._3.01* libCint.so._3.02*
---
are the 3 CINT libraries for the tree version of ROOT and
---
libCint.so
---
a link to one of them (THIS ONE MUST EXIST IN THE DIR WHERE I COMPILE!).
Naturally in the makefile there is the call to the proper version
of rootcint.
OK. If I compiled in the 3.00/06 old fashined enviroment, I succeded:
----
g++ -O -Wall -fPIC -D_REENTRANT
-I/usr/usersm/chiarusi/zonalavoro/root/include -c Lastra.cxx
Generating dictionary EventDict...
g++ -O -Wall -fPIC -D_REENTRANT
-I/usr/usersm/chiarusi/zonalavoro/root/include -c LastraDict.cxx
g++ -shared -O Lastra.o LastraDict.o -o libLastra.so
libLastra.so done
----
BUT If I compile according to the 3.01/06 and 3.02/07
I got error response:
for example, within the V 3.01/06 enviroment:
--
g++ -O -Wall -fPIC -D_REENTRANT
-I/usr/usersm/chiarusi/zonalavoro/root/include -c Lastra.cxx
Generating dictionary EventDict...
/opt/root/bin/rootcint: relocation error:
/opt/root/bin/rootcint: undefined symbol:
EnclosingSpace__12G__ClassInfo
make: *** [LastraDict.cxx] Error 127
--
while within the V 3.02/07 I got
---
g++ -O -Wall -fPIC -D_REENTRANT
-I/usr/usersm/chiarusi/zonalavoro/root/include -c Lastra.cxx
Generating dictionary EventDict...
/lxmacro_home2/chiarusi/zonalavoro/root/bin/rootcint: relocation error:
/lxmacro_home2/chiarusi/zonalavoro/root/bin/rootcint: undefined symbol:
EnclosingSpace__12G__ClassInfo
make: *** [LastraDict.cxx] Error 127
---
So they are similar error:
So my questions are:
1. What really does it means to "recompile the setup file", as expressed
in the former error message related to V 3.01/06?
2. What do I have to do?
I'm sorry if I perhaps raise again a problem that has been already solved
in this newsgroup, but I surely missed it, even if I read all the mail of
roottalk!
Thanks in advances,
Tommaso
