[Opencxx-users] no success in running the sample program

[yang qu <qu...@ya...>]

I installed the open c++ in a redhat8.0. the gcc
version was 2.96 and I used the DONT_GC preprocesor.
when I tried to run the "sample" program, I got the
following message:

  ../src/occ -- -g -L../src/Unix/libocc.a -o person
person.cc
lt_dlopen(VerboseClass.so) failed:
/export/home/qudhs/opencxx-2.6.1/sample/VerboseClass.so:
undefined symbol:
InitializeInstance__Q27Opencxx5ClassPQ27Opencxx5PtreeT1
make: *** [person] Error 1

I didn't find the symbol in opencxx.a. in libocc.a, I
got :
nm -l tmplib/libocc.a | grep InitializeInstance
0000215c T
InitializeInstance__Q27Opencxx13TemplateClassPQ27Opencxx5PtreeT1
    /export/home/qudhs/opencxx-2.6.1/src/mop.cc:1072
00000124 T
InitializeInstance__Q27Opencxx5ClassPQ27Opencxx5PtreeT1
     /export/home/qudhs/opencxx-2.6.1/src/mop.cc:74
         U
InitializeInstance__Q27Opencxx5ClassPQ27Opencxx5PtreeT1
    
/export/home/qudhs/opencxx-2.6.1/src/metaclass.cc:0

so, what should I do to correct it?
thank you in advance!
