Hello Rene,

I am a new user of root, I use the root_v2.20.Linux.2.0.33.egcs.tar
version,
 
The makefile is as follow:

but when i type make -f m_linux then show:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
g++ -g HBTProj.o -L/ROOT/root/lib -lNew -lBase -lCint -lClib -lCont -lFunc
-lGraf -lGraf3d -lHist -lHtml -lMatrix -lMeta -lMinuit -lNet -lPostscript

/usr/bin/ld: cannot open -lg++: No such file or directory
collect2: ld returned 1 exit status
gmake: *** [HBTProj] Error 1

Would you like to tell me the reason and how can i solve the problem?
                              ^^^^^      ^^^       ^^^^^
