nt_maker how to???

Your path to CernLib has to be finished by /lib , not /bin

Best
    Alexander Pukhov

HI Dr Alexander
thans for reply
i have modified the path ,but still gives me
gfortran -static -Iinclude -o ../../bin/nt_maker nt_maker_02.F readLHE.c -L/usr/CERN/2006b/x86_64-slc5-gcc34-opt/lib/ -lpacklib -lkernlib
/bin/ld: cannot find -lgfortran
/bin/ld: cannot find -lm
/bin/ld: cannot find -lquadmath
/bin/ld: cannot find -lm
/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
make: [../../bin/nt_maker] Error 1 (ignored)

while i copied the content of lib from CERN library it be
cojets.dat libeurodec.a libjetset74.a libpacklib-shift.a
eurodec.dat libfritiof.a libkernlib.a libpawlib.a
flukaaf.dat libgeant321.a libkernlib_noshift.a libpdflib804.a
gxint321.f libgeant.a libkernlib-shift.a libphotos202.a
gxint.f libgraflib.a liblapack3.a libphtools.a
isajet.dat libgrafX11.a liblepto651.a libpythia6205.a
libariadne.a libherwig59.a libmathlib.a xsneut95.dat
libblas.a libherwig.a libpacklib.a
libcojets.a libisajet758.a libpacklib_noshift.a

Do you think the problem is in CERN lib version or something ???
Thamks alot
Ahmed

This mesage means that linker can not find standard system libraties which for sure exist.

Does your gfortran work on some simple example? If yes, try to remove -static.

What do you get from "gfortran --version"?

Hi CH Authors
i removed the static when i try to compile the make file it gives me sevral copies of errors like:

Thanks alot

By googling, I have found that some people have had similar trouble with gcc 4.7. The error:

/bin/ld: cannot find -lgfortran

does not look CalcHEP specific to me.

The reason is simple.
  e_wsfe and others are F77 fortran funtions. They are not the same as gfortran ones. They come from CernLib which was compiled by F77.

Possible solitions:
                               1) add -lg2c library which contains needed functions.
Its address should be something like /usr/lib/gcc/x86_64-redhat-linux/3.4.6/libg2c.so
Check on your computer. gfortran by default should not know this path.

                                 2) use f77 instead of gfortran. In this case you more likely have to add -lgfortran.
                                       May be also path needs.
                                 3) find CernLib compiled by gFortran.
                                 4) recompile CalCHEP replacing gfortran on f77 and use f77 to collect nt_maker.

Dear Ahmed,

sorry for come late to you problem

1. could you type
echo $CERN
and let us know what it is

2. do you have g77 or f77 installed ?

3. Do you know WHICH CERN library do you have?
     Is it compiled using g77 or gfortran

4. I guess you are trying to link CERN libraries compiled with g77
    using gfortran

to solve the problem you should

a) goto $CALCHEP/c_source/mix_events
   directory

b) edit the Makefile

replacing

- $(FC) -static -Iinclude -o $@ $^ -L$(CERN) -lpacklib -lkernlib

by

- g77 -Iinclude -o $@ $^ -L$(CERN) -lpacklib -lkernlib

and making sure that

-- you have g77 complier
-- $CERN variable points to the lib directory
i.e. /cern/pro/2006b/lib/
for example

Please, let us know if this helps

Cheers,
    Sasha Belyaev

P.S.
One you have edited Makefile,
type
"make"
in the same directory, i.e.
 $CALCHEP/c_source/mix_events

if no errors appear, then you should have
nt_maker created in $CALCHEP/bin directory

HI CH Authors
i really dont know how to say that , iam very glad for your help ..
its compiled and the excutalble nt_maker apperars in bin directory .
but there is another question , i know that calchep doesnt make distr for decay process .
In GUI in Total width menu one can plot adister for parameter space , can i produce *nt file for this dister
Thanks
Ahmed

You can use CalCHEP at HEPMDB
https://hepmdb.soton.ac.uk/
to plot distributions including particles in the final state after decay
or use LHE and .nt files locally

.nt or LHE files DO have all particles after their decays
