     6Due 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*
     10which is related to a misplacement of the file  libg cc_s.so or libg cc_s.so.1.
     11To 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
     22Look to "man ln" to know how to symlink, the basic command is
     23ln -s /lib/libgcc_s.so.1 /usr/lib/libgcc_s.so.1
     24where 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'''
     28f77: ../HELAS/lib/libdhelas3.a: No such file or directory
     29To understand what's hppening go to the HELAS folder and issue "make"
     30you should get a
     31{{{
     32~/MG_ME_V4.1.24/HELAS> make
     33f77 -O -I. -c httsxx.F
     34f77: installation problem, cannot exec `cc1': No such file or directory
     35make: *** [httsxx.o] Error 1
     36}}}
     37
     38This 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}}}
     40should 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'''
     44f77: ../HELAS/lib/libdhelas3.a: No such file or directory
     45make[1]: *** [all] Error 1
     46make[1]: Leaving directory `/home/roberto/MG_ME_V4.1.24/DECAY'
     47make: *** [decay] Error 2
     48
     49If you still have this problem then change to HELAS folder and  issue
     50 make. You should get
     51{{{
     52~/MG_ME_V4.1.24/HELAS> make
     53f77 -O -I. -c httsxx.F
     54cc1: error: too many filenames given.  Type cc1 --help for usage
     55# 1 "httsxx.F"
     56make: *** [httsxx.o] Error 1
     57}}}
     58
     59To fix it you have to edit /usr/lib/gcc-lib/i586-suse-linux/3.3.5/specs
     60Open this file and look for:
     61 {{{
     62*cpp_options:
     63%(cpp_unique_options) %1 %{m*} %{std*} %{ansi} %{W*&pedantic*} %{w} %{f*} %{g*} %{O*} %{undef}
     64}}}
     65edit this line replacing "%{O*}" by "-o"
     66
     67These 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
     69To fix
     70*g77 -O2 -ffortran-bounds-check -fno-automatic -I../libraries/stdhep/src/inc -I../libraries/pgs/src -c pgs.f
     71make[2]: Target `all' not remade because of errors.*
     72
     73change to MG_ME_V4.1.24/pythia-pgs/libraries/stdhep/mcfio
     74find
     75{{{
     76FFLAGS= $(DFLG) -fdebug-kludge -fno-second-underscore
     77}}}
     78and remove "-fdebug-kludge"
