 How to compile with 64bit arch on 64bit machine:
 
 1) set the PAM_BIT environmental variable to "-m64"
 
+2) enter the directory "event" 
+
+3) mv Makefile Makefile.orig
+
+4) mv Makefile.compileon64bitarch Makefile
+
+5) edit Makefile and set the correct path for these two lines, repeated twice on lines 103/104 and 117/118 
+
+       /usr/lib/gcc/x86_64-redhat-linux/3.4.6/crtbeginS.o \
+       /usr/lib/gcc/x86_64-redhat-linux/3.4.6/crtendS.o \
+
+the correct path depends on your setup.
+
+6) remember to use 64bit external software (ROOT, MySQL, etc.)
