RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem: Compiling a C++ program using boost::mpi fails to find the symbol "boost::mpi::environment::environment(bool)" when linking


Version-Release number of selected component (if applicable): 1.41.0-25


How reproducible: Always


Steps to Reproduce:

1. Put the following into a file called stat_env.cpp
#include <boost/mpi/environment.hpp>

int main()
{
  using boost::mpi::environment;
  environment env(true);
}

2. Load the compat-mpi module with
  module load compat-openmpi-x86_64

3. Compile with
  g++ -I$MPI_INCLUDE -L/usr/lib64/openmpi/lib -lboost_mpi -o start_env start_env.cpp

Actual results:
/tmp/ccQU3mJK.o: In function `main':
start_env.cpp:(.text+0x15): undefined reference to `boost::mpi::environment::environment(bool)'
collect2: ld returned 1 exit status


Expected results:
An executable and no errors

A fix

I think this should fix the problem.  I don't quite understand how the object got compiled in the first place, as you should have hit compilation error already.  But that, too, should go away with this patch.

Oh, or are you possibly compiling against compat-openmpi or some such?  Then boost would see MPI_VERSION of 2 and expose the symbol.  But the DSO's were still built against an openmpi with MPI_VERSION 3, hence the symbol wasn't included in the DSO.

Apologies, I didn't notice you mention compat-openmpi explicitly.  No further questions then.

Verified for build boost-1.41.0-27.el6.
