            Bug ID: 199772
           Summary: math/abacus: linking against shared library fails with
                    missing symbols
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: freebsd-ports-bugs at FreeBSD.org
          Reporter: jbeich at FreeBSD.org

It seems unsatisfied references are treated differently between static and
shared variants. Stripping all symbols from object files before linking the
library *sometimes* helps.

$ echo 'int main() { }' | cc -xc -o /dev/null - -L/usr/local/lib -labacus-osi
/usr/local/lib/libabacus-osi.so: undefined reference to `ABA_SUB::generateLp()'
/usr/local/lib/libabacus-osi.so: undefined reference to
`ABA_MASTER::_initializeLpParameters()'
/usr/local/lib/libabacus-osi.so: undefined reference to
`ABA_MASTER::_printLpParameters()'
/usr/local/lib/libabacus-osi.so: undefined reference to
`ABA_MASTER::_createLpMasters()'
/usr/local/lib/libabacus-osi.so: undefined reference to
`ABA_MASTER::_deleteLpMasters()'
/usr/local/lib/libabacus-osi.so: undefined reference to
`ABA_MASTER::_outputLpStatistics()'
/usr/local/lib/libabacus-osi.so: undefined reference to
`ABA_MASTER::_setDefaultLpParameters()'

The issue existed before ports r384953 i.e., abacus-3.2.b1_4 is also affected.
