Undefined symbol in static lib linked into dynamic library

Question

here is my issue:

At runtime my program which load shared library fail to load one, it says:

libCommunicationModule.so: undefined symbol __builtin_delete

the context:

• compiler: gcc 3.4
• Linux Debian 4.0 (old stuff ....)

I have a static library: libtgi_cppd.a , I don't have the source of this library. This lib is linked into the shared library libCommunicationModule.so with these options -Wl,-whole-archive -ltgi_cppd

I enabled -y option on __builtin_delete to check:

libtgi_cppd.a(ClientAPI_cpp.o): reference to __builtin_delete
libtgi_cppd.a(ClientInterface.o): reference to __builtin_delete
libtgi_cppd.a(ClientAPI_cpp.o): reference to __builtin_delete

I try to add to link command -lstdc++ -lgcc before and after -whole-archive , no change.

$ nm libCommunicationModule.so | grep __builtin

result is always like this:

     U __builtin_delete
     U __builtin_new
     U __builtin_vec_new

What can I do to solve this issue?

Thank you

Answer 1

You linked against a library which was compiled/linked by another compiler/linker version. What you need is to link against a library which was compiled and linked by the same compiler/linker as used by yourself, or you have to make sure, that the libraries are at least binary compatible.

Answer 2

1. Execute command ldd and it will list out all shared libraries using by your program.

2. Check the environment variable LIBPATH /LD_PATH in your execution environment. And make sure all those libraries are present in that path

3. Make sure all library files have sufficient permission
