The command line for creating libblob.la (run from 
/home/loose/LOFAR/LCS/Blob/build/gnu_debug) :

/bin/sh ../libtool --tag=CXX --mode=link /usr/bin/g++  -g -W -Wall 
-Woverloaded-virtual -Wno-unknown-pragmas       -pthread  
-L/usr/local/log4cplus/gnu/lib -R/usr/local/log4cplus/gnu/lib

The command line for the relink step (run from
