            |  | 5 |  | 
          
            |  | 6 | Due to some "non-standardness" of SuSe 10.2 the straight setup procedure of MG_ME_V4.1.xx doesn't work. Here follows how it worked on several workstation running SuSe 10.2 both i586 and x86_64. | 
          
            |  | 7 |  | 
          
            |  | 8 | * First issue is | 
          
            |  | 9 | */usr/lib/gcc-lib/i586-suse-linux/3.3.5/../../../../i586-suse-linux/bin/ld: cannot find -lgcc_s* | 
          
            |  | 10 | which is related to a misplacement of the file  libg cc_s.so or libg cc_s.so.1. | 
          
            |  | 11 | To solve this issue symlink the  libgcc_s.so where is missing i.e. when you run locate libg cc_s.so you should match the following list (for x86_64 system). | 
          
            |  | 12 |  | 
          
            |  | 13 | {{{ | 
          
            |  | 14 | ~>locate libgcc_s.so | 
          
            |  | 15 | /lib/libgcc_s.so.1 | 
          
            |  | 16 | /lib64/libgcc_s.so.1 | 
          
            |  | 17 | /usr/lib/libgcc_s.so | 
          
            |  | 18 | /usr/lib/libgcc_s.so.1 | 
          
            |  | 19 | /usr/lib64/gcc/x86_64-suse-linux/4.1.2/libgcc_s.so | 
          
            |  | 20 | }}} | 
          
            |  | 21 |  | 
          
            |  | 22 | Look to "man ln" to know how to symlink, the basic command is | 
          
            |  | 23 | ln -s /lib/libgcc_s.so.1 /usr/lib/libgcc_s.so.1 | 
          
            |  | 24 | where the first path is the link target and the second is the link | 
          
            |  | 25 |  | 
          
            |  | 26 | * Second issue is | 
          
            |  | 27 | '''f77 -O -ffixed-line-length-132 -o decay  decay_couplings.o decay.o decay_matrix.o decay_mom.o decay_event.o vegas.o decay_printout.o hdecay.o ran1.o rw_events.o open_file.o alfas_functions.o ../HELAS/lib/libdhelas3.a''' |

            |  | 29 | To understand what's hppening go to the HELAS folder and issue "make" | 
          
            |  | 30 | you should get a | 
          
            |  | 31 | {{{ | 
          
            |  | 32 | ~/MG_ME_V4.1.24/HELAS> make |

            |  | 35 | make: *** [httsxx.o] Error 1 | 
          
            |  | 36 | }}} | 
          
            |  | 37 |  | 
          
            |  | 38 | This is related to the missing compiler cc1, you just need to put into the PATH. Again a symlink is enough to make MG | 
          
            |  | 39 | {{{n -s /usr/lib/gcc/i586-suse-linux/4.1.2/cc1 /bin/cc1}}} | 
          
            |  | 40 | should work on most  10.2-i586. | 
          
            |  | 41 |  | 
          
            |  | 42 | * Third issue is again | 
          
            |  | 43 | '''f77 -O -ffixed-line-length-132 -o decay  decay_couplings.o decay.o decay_matrix.o decay_mom.o decay_event.o vegas.o decay_printout.o hdecay.o ran1.o rw_events.o open_file.o alfas_functions.o ../HELAS/lib/libdhelas3.a''' |

            |  | 48 |  | 
          
            |  | 49 | If you still have this problem then change to HELAS folder and  issue | 
          
            |  | 50 | make. You should get |

            |  | 58 |  | 
          
            |  | 59 | To fix it you have to edit /usr/lib/gcc-lib/i586-suse-linux/3.3.5/specs |

            |  | 66 |  | 
          
            |  | 67 | These are all the erros i had to fix to make MG compile on suse linux, other happen if you want also '''pythia-pgs'''. Next i'll show how to fix these. | 
          
            |  | 68 |  |
