HEAsoft v6.26.1 - Known Issues

If you are using HEASOFT v6.25 and don't want to upgrade to v6.26.1 just yet, see the HEASOFT 6.25 Issues List.

Several packages track issues separately from this page:

The following is a list of known issues in v6.26 of HEAsoft not covered by the above pages.

  • ftrbnrmf (rbnrmf): In HEASOFT 6.26 & 6.26.1, the ftrbnrmf task (to which rbnrmf is now a wrapper) contains a bug which prevents it from processing a negative binning factor (ebfact), i.e. when you wish to omit channels, resulting in an "InconsistentGrouping" error message. A fix is available, and you may update your existing HEASoft 6.26[.1] source code distribution in the following way:

      1) Download this file (grouping.cxx)
    
         and copy it into this directory:
    
           heasoft-6.26[.1]/heacore/heasp/
    
      2) Initialize HEASoft, then rebuild and re-install libhdsp:
    
         $ cd heasoft-6.26[.1]/heacore/heasp
         $ hmake all
         $ hmake install
    
    
  • rbnrmf with binfile: (Patch included in HEASOFT 6.26.1)

    In HEASOFT 6.26, the old rbnrmf task is now a wrapper to the newer task ftrbnrmf. The wrapper version (1.0) originally included in 6.26 contains a bug which prevents it from rebinning the response when a binfile is used (as for example in the XTE task pcarsp). For older 6.26 installations, please migrate your applications to use ftrbnrmf instead, or if needed, download the fixed version of rbnrmf (version 1.1), copy it into your $HEADAS/bin directory, and run the lhea-fixperl script on it to make it ready for use:

      $ cp rbnrmf $HEADAS/bin
      $ lhea-fixperl $HEADAS/bin/rbnrmf
    

  • pcarsp (RXTE):

    The RXTE script pcarsp invokes rbnrmf with the deprecated fchan parameter (see above), and will therefore exit with the error "fchan=0 is no longer allowed; Please see the help file for rbnrmf". If needed, please download an updated version of pcarsp, copy it into your $HEADAS/bin directory, and run the lhea-fixperl script on it to make it ready for use:

      $ cp pcarsp $HEADAS/bin
      $ lhea-fixperl $HEADAS/bin/pcarsp
    

  • XRONOS on newer Debian systems (e.g. Ubuntu 18.10 & newer):

    Some of the older, Fortran-based XRONOS tasks (including autocor, crosscor, efold, efsearch, lcstats, lcurve, listdata, powspec, and timeskew) suffer memory faults when built on newer Debian Linux systems (e.g. Ubuntu OS 18.10 and 19.04). This issue will be resolved in a future HEASoft release or patch.


  • XIMAGE and gfortran 8.x (or newer) on macOS:

    When built with the Apple XCode C compiler paired with gfortran version 8.x or 9.x, ximage may generate "Invalid header key" messages and a Tcl error "Failed to run tcl: pgtk::upcopy MAP1 MAP9". Subsequent attempts to display the image may then result in a segmentation fault. Note that this problem will affect tasks that use ximage such as xrtpipeline or nupipeline. Our current suggestion is to use one of the other Fortran compilers recommended in our Mac installation guide. Note for example that SourceForge provides gfortran v7.3 for High Sierra, and the problem with ximage is not present when HEASOFT is built using it.

    An additional alternative is to use all of the GCC 8.x or 9.x compiler suite (i.e. not just gfortran) and build HEASOFT using the complete set of 8.x compilers, for example, if using MacPorts:
        % setenv CC /opt/local/bin/gcc-mp-8       % export CC=/opt/local/bin/gcc-mp-8
        % setenv CXX /opt/local/bin/g++-mp-8      % export CXX=/opt/local/bin/g++-mp-8
        % setenv FC /opt/local/bin/gfortran-mp-8  % export FC=/opt/local/bin/gfortran-mp-8
    
      Or, if using GCC 8.x from HPC/SourceForge:
    
        % setenv CC /usr/local/bin/gcc            % export CC=/usr/local/bin/gcc
        % setenv CXX /usr/local/bin/g++           % export CXX=/usr/local/bin/g++
        % setenv FC /usr/local/bin/gfortran       % export FC=/usr/local/bin/gfortran
    
    This combination should result in a working ximage.

  • Perl symbol lookup error, "undefined symbol: Perl_Gthr_key_ptr":

    If running a HEASOFT Perl script generates an error similar to the above, it may result from a Perl version incompatibility (common when using the pre-compiled binaries), but it may also occur if you have the VERSIONER_PERL_PREFER_32_BIT environment variable set to "yes". If "echo VERSIONER_PERL_PREFER_32_BIT" returns "yes", then unset it:

       unset VERSIONER_PERL_PREFER_32_BIT
    
    or, in C-shell:
    
       unsetenv VERSIONER_PERL_PREFER_32_BIT
    
  • Mac "configure failed..." Fortran compiler issue:

    The configure script may generate an error ("Configure failed in the AST package!", or "configure failed for heacore component fftw!") resulting from a MacPorts assembler (as) under /opt/local/bin being ahead of the default Apple /usr/bin/as in a user's PATH (which may result from an automated change made to .profile during a MacPorts installation). To get past this issue, put /usr/bin at the front of your PATH:

       export PATH="/usr/bin:$PATH"
    
  • MacPorts "unexpected token" linker issue:

    If you are using MacPorts compilers in your build, 'make' may fail when building the HEASoft source code distribution with an error referring to a new Xcode linker ("ld") format ("tbd"), e.g.:

    ld: in '/System/Library/PrivateFrameworks/CoreEmoji.framework/Versions/A/CoreEmoji.tbd', unexpected token: !tapi-tbd-v2 ...
    
    The underlying issue is discussed here and here; it appears that when new versions of the XCode command line tools are released, problems such as this may affect MacPorts compilers until they catch up with Apple's changes. Users should be able to get around the error in our build by installing the MacPorts 'xcode' variant of the linker ld64 as a temporary measure:
    
        sudo port install ld64 +ld64_xcode
    
    
    and when MacPorts eventually supports the latest XCode command line tools, you can switch back to the latest ld64 with the following:
    
        sudo port install ld64 +ld64_latest
    
    
  • Mac "suffix or operands invalid for 'movq'" Fortran compiler issue:

    When using the gnu.org gfortran binaries note their recommendation that when installing new versions of the compiler you should remove the previous gfortran installation first:

       $ sudo rm -r /usr/local/gfortran /usr/local/bin/gfortran
    
    Failure to do so may result in a corrupted compiler installation, leading to the "suffix or operands invalid for 'movq'" error.


  • Cygwin build error "execvp: ./makeuctb.exe: Permission denied":

    When building HEASOFT while anti-virus software is running in the background, users may receive the error above from 'make' while in the lynx package. The solution is to disable any anti-virus software for the duration of the HEASOFT build. It may be re-enabled once the build is done (i.e. after running 'make' but before running 'make install').

  • Ubuntu ds9 & HEASoft:

    After initializing HEASoft on Ubuntu Linux, the ds9 GUI (if installed) may fail to start up (saying "can't find package xml" or "can't find package uri 1.1"). This results from incompatibilities between the Tcl/Tk included with HEASoft and the Ubuntu system libraries. Until a more elegant solution can be devised, we recommend that users try one of the following options, depending on the file type of your ds9 (shell script or compiled executable - check the output from "file `which ds9`" to determine which it is):

    
    1) If ds9 is the shell script version, edit it to change the line
    
         exec wish8.6 -f ${DS(_HOME-/usr/share/saods9}/library/ds9.tcl $*
    
       to
    
         exec /usr/bin/env -u LD_LIBRARY_PATH /usr/bin/wish8.6 -f ${DS9_HOME-/usr/share/saods9}/library/ds9.tcl $*
    
    or
    
    2) If ds9 is the compiled executable version, create a new file
       "$HEADAS/bin/ds9" containing the following lines:
    
         #!/bin/sh
         exec /usr/bin/env -u LD_LIBRARY_PATH /usr/bin/ds9 "$@"
    
       (Note this assumes that `which ds9` = /usr/bin/ds9)
    
       To make the new script executable, run the following command:
    
         $ chmod +x $HEADAS/bin/ds9
    
       Then, as long as $HEADAS/bin is ahead of /usr/bin in your PATH, you
       should now be able to successfully run ds9 from the command line:
    
         $ rehash
         $ ds9
    
    


  • "relocation R_X86_64_32 against `.rodata' can not be used when making a shared object":

    Users building HEASoft from the source code distribution may run into this error which refers to a "Bad value" in the file heacore/wcslib/C/cel.o, from which the linker "could not read symbols". It also suggests that you "recompile with -fPIC". This situation most likely occurrs when users perform a re-build after a previously unsuccessful build attempt. To get past this issue, try the following:
    
       $ cd heasoft-6.26/BUILD_DIR
       $ make distclean
    
    
    When that finishes, restart the build procedure beginning with "./configure", then "make", and let us know if this does not resolve the problem.


  • fv - XPA_METHOD:

    Some users of the fv GUI may experience long delays at startup, or error messages of the type "XPA$WARNING: xpans needs to be running on this machine", or "XPA$ERROR: invalid host name specified: $host:$port" (when using the ds9 display device). These issues tend to occur on Macs with customized firewall settings, or on machines without valid IP addresses. This can be resolved by setting the XPA_METHOD environment variable to the value "local" (to use local/UNIX sockets instead of inet sockets):
    
            export XPA_METHOD=local          # Bourne shell (bash/sh)
    or
            setenv XPA_METHOD local          # C-shell (csh/tcsh)
    
    
  • Perl version mismatch::

    Pre-compiled Perl libraries used extensively by mission software (Swift, Suzaku, NuSTAR) and other packages are not especially portable, so we generally recommend building HEASoft from the source code distribution.


  • xspec / PLT - wenv, whead, wdata:

    Some GNU Fortran compilers (gfortran 4.4.x, 4.0.x, 4.1.x) appear to have internal issues which prevent the PLT commands wenv, whead and wdata from working unless an output file is specified; i.e. attempts at producing terminal output may fail with "Fortran runtime error: Invalid argument". To get around this, provide an output file name when using these commands, for example:
         wenv myFile1.qdp
         whead myFile2.qdp
         wdata myFile3.qdp
    


  • HEASoft and other software packages (CIAO, XMM-SAS):

    Please note:

    Users may wish to download and run our hwrap script to create an alternate runtime environment for HEASOFT to help avoid conflicts with other software packages, but if not, please take note of the potential pitfalls below:

    • CIAO:

      Please see the following notes at the CXC website regarding the potential dangers of using CIAO and HEASOFT together in the same session:



    • XMM:

      When the XMM-SAS is initialized after HEASoft (when both are used in the same session), the SAS setup changes the value of the environment variable PGPLOT_FONT with the result that plots in e.g. Xspec may (or may not, depending on the software distributions in use) have no axis labels or values. Users can fix this by resetting PGPLOT_FONT to point to the HEASoft location:
           C-shell:
      
               setenv PGPLOT_FONT $HEADAS/lib/grfont.dat
      
           Bourne shell:
      
               export PGPLOT_FONT=$HEADAS/lib/grfont.dat
      
        
      or by simply re-initializing HEASoft:
           C-shell:
      
               source $HEADAS/headas-init.csh
      
           Bourne shell:
      
               . $HEADAS/headas-init.sh
        
      This may in turn have consequences for plotting in XMM-SAS, in which case users may need to return PGPLOT_FONT to the SAS setting when using it for data analysis.
