Hoi, I modified RecoilAnalysis/ntuplesLinkDef.h and VubAnalysis/main.mk and then I get with the HEAD of CVS (also tagged as ursl-050301) two running executables by doing on a yakut newrel -t analysis-24 vub cd vub/ srtpath 16.0.3 Linux24SL3_i386_gcc323 addpkg RecoilAnalysis addpkg VubAnalysis make installdirs cd RecoilAnalysis/ make -f Makefile lib cd ../VubAnalysis/ make -f Makefile clean b2u anaQA ../bin/Linux24SL3_i386_gcc323/b2u I guess this means that the s/w is running also in analysis-24 (though there was never a close coupling to BABAR releases anyway, a testrelease was just a way to use addpkg ...) Someone who knows about linkdef files should cleanup the linkdef files in both directories (they are such an organically grown compost that it is embarrassing). I admit that I don't know anything about linkdef files ... Cheers, --U.
