Stt external library glpk [message #10098]

Hi,

Running on my Mac I noticed in pandaroot/stt/CMakeLists.txt:72 that libglpk.so is loaded. However the Mac compiles this external package into libglpk.dylib causing stt to not compile.
Is there an approach in cmake to load either library type?

Regards, Ralf.

I had the same problem.
Make symbolic link to .dylib with a name of .so.
I also had later to add the glpk dir name to $DYLD_LIBRARY_PATH.

Hope this helps.

yours,
radek

Hi,

Mohammad has modified the installation scripts of the external packages now, which makes the link to an .so file to keep the MAC compatibility. You can fetch the new SVN revision 7719 with the update.

Another addition related to the glpk libraries: the corresponding (.so and .a) files in the external packages are now copied to the directory ${SIMPATH}/basics/glpk/lib/. On my machine, this was needed, otherwise running the macros didnt succeed since it couldnt find the libs. However, in the CMakelist in the "stt" directory, the GLPK_LIB_DIR is still set to ${SIMPATH}/basics/glpk/src/.libs. I would like to change this asap to ${SIMPATH}/basics/glpk/lib in stead to be uniform with the rest of the links to external libraries. This would require that everyone updates his external package and rerun the installation of the "glpk" stuff: svn up, remove the glpk directories in basics, and rerun "configure.sh". Let me know if anyone has major objection against this "small" change.

Johan.

I agree with this change.
The reason for having the .libs directory was only 'historical' (that is the way the directories are arranged in the original web site from where I downloaded the libraries).

Dear all,

The change in the CMakeList has been made in rev 7740. So if you encounter problems, update the external packages, remove the directory glpk (in basics), and rerun the configure.sh....

Hi,
I have updated the external packages and so on, but now, when loading all the pandaroot libraries, I have the following error:

- RTDB container factory FairBaseContFact
- RTDB container factory PndFieldContFact
- RTDB container factory PndPassiveContFact

PSaid instance created...  access via gSaid->f()

- RTDB container factory PndEmcContFact
- RTDB container factory PndTpcContFact
dlopen error: libglpk.so.0: cannot open shared object file: No such file or directory
Load Error: Failed to load Dynamic link library /home/spataro/jan10/cbuild/lib/libStt.so
(int)(-1)

library which of course is inside basics/glpk-4.39/lib

What should I do now?

And another question: do we really need to use glpk inside our code? I suppose root classes are doing the same job, or maybe there is another reason?

Hi,

Looks like there is still a link missing in the external packages, I have noticed this on the Dashboard as well. Mohammad, could you add the appropriate links. Probably, it makes sense just to copy all the libs in "src/.libs" to "/lib", not to miss anything for whatever system. For the moment, I changed the stt CMakeList to the old version again, to avoid the problems.

Concerning your second question, about whether to use glpk at all.... I agree with you that if the same functionalities can be found in root or other previously existing external packages, one should take that to minimize the dependencies. Maybe, Gianluigi can comment on this.

Greetings,

Johan

It seems the problem stays in the missing file libglpk.so.0.
It is not clear to me why the code is searching exactly for libglpk.so.0, while libglpk.so and libglpk.a are existing and at the proper place.

However,
in my pc I have fixed it in the following way:

cd jan10/basics/glpk/lib
ln -s libglpk.so libglpk.so.0

I suppose another should be the official fix.

Hi,
yes there are a couple of essential reason.

As far as I know there is no equivalent to GLPK in root.

GLPK is a pakage for performing minimizations of some function that is linear in the parameters to fit AND ALSO in the case when some of the parameters are INTEGER variables.

This branch of the minimization programming is called Mixed Integer Linear Programming (MILP) as I explained in many presentations on the STT pattern recognition.

So GLPK is a package for doing MILP.

The main reason why I chose it is that it is superfast compared to Minuit, so I can use it in the pattern recognition.

Also MILP has the nice feature that, thanks to the use of some integer variable, enables to :
a) resolve the left-right ambiguity typical of the straw tubes;
b) eliminate those hits which are clearly noise, authomatically already in the fit.

Without GLPK the STT real pattern recognition doesn't work.

Cheers Gianluigi

Hi,

So, finally the glpk is done properly! it is in SVN please remove glpk and glpk-4.39 in your $SIMPATH/basic dirctory, make an svn update (release jan10) and run the configue.sh script again, it will only install glpk.

regards

Mohammad

Done,
but now the src folder has disappeared:

Scanning dependencies of target Stt
[ 23%] Building CXX object stt/CMakeFiles/Stt.dir/PndSttTrackFinderReal.o
[ 23%] Building CXX object stt/CMakeFiles/Stt.dir/PndSttDict.o
make[2]: *** No rule to make target `/home/spataro/jan10/basics/glpk/src/.libs/libglpk.so', needed by `lib/libStt.so.0.0.0'.  Stop.
make[1]: *** [stt/CMakeFiles/Stt.dir/all] Error 2
make: *** [all] Error 2

There was the CMakeList wrong. I have fixed it.
