Hi Sylvio,
Could you tell version of otb gdal you are using and about how you
installed them.
For source build of OTB it is very very important to have read at

*Hi all,
I'm trying to launch a SVM classification on a raster with 34
bands like this :*
------------------------------------------ COMMAND
---------------------------------------------------
/usr/local/bin/otbcli_TrainImagesClassifier -io.il
<http://io.il> Raster_34bands.tif -io.vd Shp_Apprentissage.shp
-io.imstat XML_Raster_34bands.xml -sample.mt <http://sample.mt>
1000 -sample.mv <http://sample.mv> 1000 -sample.edg false
-sample.vtr 0.5 -sample.vfn Class -classifier libsvm
-classifier.libsvm.k linear -classifier.libsvm.c 1
-classifier.libsvm.opt true -io.out SVMModel_Raster_34bands.model
----------------------------------------------------------------------------------------------------------------

On my computer, I get this error :*

I think there is not enough memory on my computer, **so I
launched the same command on **a server with a larger memory.
I get a another error :*

*I don't understand why !!!
I checked paths of the files and they are correct.
I launched this command on a raster with a band and it works.
The server responsable gave me the out GDB :*
