problem of Unable to read layout--no header lines found

[jcytsai]

Dear Drs. Soliday and Yao,

Recently I had a parallel version of ELEGANT installed on local machines (compiling from source codes). After overcoming some installation issues, now PELEGANT can run successfully. However, I met an error message when using smoothDist6s under this installation; let me copy the message below:
-----
Error5: unknown keyword/value given: 1.2
Error (sddshist): invalid -majorOrder syntax/values
Error for sddssmooth:
Unable to read layout--no header lines found (SDDS_ReadLayout)
Error for sddsprocess:
Unable to read layout--no header lines found (SDDS_ReadLayout)
-----

Using this smoothDist6s (or, specialized tools) in another situation (with prebuilt rpm downloaded from the website) has no problem and works perfectly. I have no idea where goes wrong with this situation/installation; could you help resolve this issue or suggest some specific diagnostic steps for me? I am new to linux environment; just let me know if I can provide you for further information. Thank you very much for the help!

Best regards,
Cheng-Ying
ps. the OS is CentOS 64 bit

You uncovered a bug in sddshist. The -expand and -majorOrder options got swapped. I am fixing it in our source code, but if you have your own copy, edit extensions/src/SDDS/sddshist.c and change line 109 so that "expand" comes before "majorOrder" and not the reverse like it is now.

Dear Dr. Soliday,

I tried what you suggested; the previous error message disappeared. Instead, it shows

couldn't execute "sddsanalyzebeam": no such file or directory

When looking into oag/apps/src/elegant/elegantTools/ directory, I found sddsanalyzebeam.c. What does it mean?
Just to make sure: is the file sddshist.c in extensions/src/SDDS/sddshist.c? I found it in extensions/src/SDDS/SDDSaps/sddshist.c, so I modified the file in the SDDSaps directory. I feel this may almost be resolved.

Thank you very much for the help!

It means that you probably didn't compile the code in the elegantTools directory. Go to that directory and run "make" and it should create the O.linux-x64_64 subdirectory containing various programs including sddsanalyzebeam. It will also be copied over to the oag/apps/bin/linux-x86_64 directory.

Dear Dr. Soliday,

Thanks for your quick reply.
I just run "make" under the oag/apps/src/elegant/elegantTools directory and it does create O.linux-x86_64 under the same directory and those programs found at the oag/apps/bin/linux-x86_64 directory. However, the same error message shows:

couldn't execute "sddsanalyzebeam": no such file or directory

Is it possibly due to missing some path variable setting? because when using like smoothDist6s I need to type in command line "/home/jcytsai/pelegant/oag/apps/src/elegant/elegantTools/smoothDist6s", otherwise it would show the information like (if I just type "smoothDist6s")

smoothDist6s: Command not found

I just checked Installation Guide (http://www.aps.anl.gov/Accelerator_Syst ... node2.html) and, according to the guide, current instllation only has the following environment variables and path set:

set path=(/home/jcytsai/pelegant/epics/extensions/bin/linux-x86_64 $path)
set path=(/home/jcytsai/pelegant/epics/base/bin/linux-x86_64 $path)
set path=(/usr/mpi/gcc/mvapich2-1.8/bin $path)
set path=(. $path)
setenv HOST_ARCH linux-x86_64
setenv EPICS_HOST_ARCH linux-x86_64
setenv RPN_DEFNS /home/jcytsai/pelegant/defns.rpn

Thanks again for your kind help!

Yes, it has to be in your PATH environment variable or you will not be able to execute it without using the full path name. I figured since it goes in the same oag/apps/bin/linux-x86_64 directory that elegant goes to, that you already had it in your path.

Dear Dr. Soliday,

After adding oag/apps/bin/linux-x86_64 into the PATH, it is working now.
Thanks for your quick reply and very helpful information!
