IT36950: IBM MQ installation might cause failure in non-IBM MQ programs that use libcurl or libedit libraries

APAR status

• Closed as program error.

Error description

• IBM MQ installation might cause failure in non-IBM MQ programs
  like yum, python etc. that use libcurl or libedit libraries if
  the user runs ldconfig before running the non-IBM MQ programs.
  
  Example:
  
  sudo ldconfig
  sudo yum update
  
    /usr/lib64/python2.7/site-packages/pycurl.so: undefined
  symbol: CRYPTO_num_locks
  

Local fix

• Remove the line that contains "/usr/lib64" in
  /etc/ld.so.conf.d/mqm.conf before running ldconfig
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of IBM MQ who run ldconfig before running any non-IBM MQ
  programs that use libcurl or libedit libraries.
  
  
  Platforms affected:
  Linux on x86-64, Linux on zSeries, Linux on x86, Linux on S390
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  IBM MQ ships libedit and libcurl libraries with the product and
  installs them to the IBM MQ installation directory. These
  libraries might also be installed by the user or the OS in
  /usr/lib64.
  IBM MQ adds "/usr/lib64" to /etc/ld.so.conf.d/mqm.conf during
  the installation. This might cause
  conflict in libraries on non-IBM MQ programs if the user run
  ldconfig before running the program.
  The "/usr/lib64" in /etc/ld.so.conf.d/mqm.conf is required only
  for the primary installation.
  

Problem conclusion

• The IBM MQ code has been modified to add "/usr/lib64" in
  /etc/ld.so.conf.d/mqm.conf only for the primary installation.
  
  Users who have configured the IBM MQ primary installation and
  see a library conflict with IBM MQ installed libraries
  are recommended to unset the primary installation before running
  ldconfig.
