List of known bugs

98 release

• Externals users of Fatmen and Hepdb have reported problems with zserv.
  • The 97a version has been reinstated as the pro version on all the Unix platforms in asis and asisftp on Monday 18th May. Very few CERN users need or use this program due to the network connectivity of computers on the site.

• Linux linking problems, undefined reference to `G77_lnblnk_0'.
  • The way g77 generates calls to some Fortran Library routines is not compatible with earlier versions of g77. The exact level is not clear, but at least 5.2.19 (97a is with 5.2.18) is incompatible and applications using f2c have reported problems. The changes are in the library libf2c.a (or libf2c.so). So far, it looks like the problem for Cernlib is restricted to the call generated for the function lnblnk, used by many routines in packlib, which was _lnblnk in 5.2.18 and is now G77_lnblnk_0.

    A copy of libf2c.a (g77_5_21_libf2c.a) has been added to the lib directory and it should be possible to link in the new externals.

• Year 99 problems with Fatmen and Hepdb.
  • The likely symptoms are the message

     FMPUT. errors detected by FMVERI - entry will not be added to catalogue
    

    The error is in FMUPTM, which is in packlib, and also affects the modules fatmen, fatnew and fatsrv.

    This error can be made non-fatal by using

    SET/VERIFY OFF
    

    or with the callable interface using

              CALL FMSETV(0,IRC)
    

  • There is a similar error in CDUPTM in packlib, affecting the modules hepdb and cdserv.
  • The corrections for all these products are in the 99 pre-release of January 1999 for the CERN supported Unix platforms. Users of other systems or with special applications can download the Fortran versions of fmuptm and cduptm and compile them locally.

• List of changes to PAW.

• List of changed routines since the 98 release

97A release

• Zebra/RZ files with different record lengths were opened using the first length for all files. Known to affect the ATLAS program atrecon which was corrected locally.
  • There are corrected versions of rzfdir.o and rziodo.o in the /cern/97a/lib directory for all the Unix platforms.

• Solaris linking problems or missing libF77.so.3 are due to incompatibility with f77 4.0.
  • Upgrade to f77 4.0.

• Alpha-OSF32 linking problems are due to incompatibility with f77 4.0.
  • Upgrade to f77 4.0.

• PDF 7.09
  • After a period of testing, the pro version of libpdflib.a was replaced on all the Unix systems on 30th September 97.

• List of changed routines since the 97a release

96A release

• CFIO problems: as from the 96A release of CERNLIB, the KERNLIB CFIO routines interface to the SHIFT RFIO package. There are currently problems opening files when the file name specified is in fact a link, which points to another link that uses relative pathnames.
  • Workaround: use absolute pathnames

  This bug is corrected since 17/18-May-96. kernlib, packlib and all modules affected were updated.

• To avoid the following link error on HP/UX, please use the CERNLIB command:
  • fort77 your.o `cernlib packlib`

  /bin/ld: Unsatisfied symbols:
   fpclassifyf (code)
  *** Error code 1
  

  This is not a bug in the libraries itsself. Hbook now has routines to check the validity of floating point numbers. The routines are provided by default only on PA1.1 systems ( all but hp710, hp720 ?), on other this must be done explicitely. The cernlib command does this; you may also add /lib/pa1.1/libm.a explicitly.

• Files missing in /cern/pro/src/car

  As has been discussed in a number of articles in the CERN computer newsletter over the last two years, we have switched to new code management and installation tools for the 96A release of the CERN Program Library.

  This means that the CERNLIB source files are NO LONGER AVAILABLE in PATCHY or CMZ format (except in the OLD area.)

  If you habitually use these files, e.g. to pick up "sequences", we would recommend that you move to using "#include files", as processed by the C pre-processor. Examples of how to do this will appear shortly on the CERNLIB web pages, accessible here

  To ease the migration process, we will place copies of those "car" files that are needed in the /cern/pro/src/car area, containing only the sequence definitions. If you need one or more of these files, please send a mail to heplib.support@cern.ch stating which files you require.

• Can't find library for -lgenlib

  Although it was not stated explicitly in CNL 207 in 1992, genlib in fact disappeared then and the CERNLIB command linked to mathlib instead. In addition, a link was made pointing to mathlib on all systems with the risk that it might sometimes be forgotten. In the belief that most users are using the cernlib command or explicitly referencing mathlib, we have decided to discontinue making this link. The use of the CERNLIB command is strongly recommended as it also provides other benefits, the most important being to platform specific system libraries (eg. X11) which are required by some Cernlib products. At CERN, in addition, the hepf77 command provides a portable interface to the native Fortran compilers, so we recommend for most applications, to link with-

   hepf77 your.f `cernlib packlib mathlib kernlib`
  

  We are sorry for the inconvenience this is causing some users, but expect that removing the confusion about the existence and location of genlib will provide lasting benefits.

• kernnum routines are not optimised

  By mistake all routines of kernnum were compiled without optimisation on all systems. As an effect it was reported that some programs now take twice the time to complete. This is corrected on all systems (except SunOs) in kernlib/packlib since 12-June-96.

• Epio on SGI changes sign of floating point numbers.

  This bug is caused by a EPIO utility routine called ctoibm. This is not used by EPIO itsself. The bug is a compiler problem. The affected routine was recompiled by a "better" compiler.

  This is fixed in packlib on SGI since 12-June-96.

• radmul/dadmul missing from mathlib (D120)

  This is a new routine for mathlib in 96a, announced in CNL 221.

  This is fixed since 14-June-96 for all Unix, and since 21-June for VMS (both Alpha and VAX version).

95A release

paw++ in HP/UX

Problems corrected in 95a

• geant++: picking problems, due to a bug in KUIP
  • Fix available, being tested
• geant++ (HP only): crashes, due to problems with Motif/XXX
  • Update Motif/X11 to latest version
• PAW/GEANT: problems using shared libraries (COMIS)
  • Fix will be made next week
• Geant: again picking problems (HIGZ) - same behaviour in 94B
• CMZ (OSF): cannot connect files
  • Use 1.46 as workaround
  • New version will be installed and tested early next week

94B release

NYPATCHY on Solaris

PAW++ on VMS systems

ZEBRA/RZ

This problem has now been fixed in the PRO areas at CERN. See hot news for more details.

RTOA/RTOX commands and ZFTP/RTOF subcommand

KUIP

           Warning concerning the BUGREPORT command
           ========================================

 Due to a bug in KUIP, the new command BUGREPORT doesn't work 
 correctly in the PRO version of PAW. This problem will be fixed 
 in the NEW area. 
 Alternatively, continue to submit bug reports as previously.

ZFTP/ZSERV (CSPACK)

• Problems with transfer of RZ files - !!! NOW SOLVED !!! (28th October)

Recommended solution is to use prescription described in CNL217 for transfer of RZ and other files.

Use the version of ZSERV from the NEW area. On CERNVM, add 'SETENV CERN_LEVEL NEW' to get the new version automatically. The problems were due to incompatible sequences between CSPACK and HBOOK.

KUIP

• The KUIP EDIT command always adds the file extension ".kumac" to files with no extension.
• READ is an unresolved external reference on VM systems, unless the X11 libraries are also included. Seems to be benign.

  Access the X11 libraries via "CERNLIB (X11"

COMIS

• Problems with dynamic compilation and linking

  A fix to these problems has now beem applied in the PRO area

EPIO

• VAX version currently gives warning at link stage. (EPIOVAX).

  A fix has now been applied to the PRO area on VXCERN (and the master source repository on asisftp.cern.ch)

• AXP version currently gives informational message at compile stage.

  Can be suppressed by compiling /NOWARN.

PAW

• The following problem was fixed in the PRO area on Friday, 21-OCT-1994

  -----------------------------------------------------------
  * Give a short description of the bug *
   
  With several ntuples, when looping over ntuples with n/plot, there
  will be error messages
   
  ***** ERROR in HGNT : Bank does not exist : ID=      25
  ***** ERROR in PPROJN : Error reading Ntuple : ID=      25
   
  And the resulting histogram looks wrong.
   
  This worked correctly with the previous version of PAW.
  

FATMEN

• The VM version of the FATMEN shell will print a traceback if the pathname given to the CD command terminates with a slash, e.g. cd frodo/.

  Workaround: specify a valid pathname

HIGZ/HPLOT

• IBM/VM users of GRAFLIB (HPLOT) or HIGZ (GRAFGKS, GRAFX11, GRAFGDDM)

                 *** For IBM/VM users ONLY ***
  
  In the new CERNLIB release (94B), all the versions of HIGZ
  (GRAFGKS, GRAFX11, GRAFGDDM) contain C code. In the previous
  release only GRAFX11 had C code. So, a CALL INITC() at the
  beginning of the main program is now mandatory for all the
                   ^^^^^^^^^^^^
  programs using GRAFLIB (HPLOT) or HIGZ (GRAFGKS, GRAFX11, GRAFGDDM)
  on IBM/VM. This call (a dummy C routine) forces the loading
  of the C library. This routine is in KERNLIB.
