Hi all: I have successfully worked with Boost.Python on windows. However I am having some trouble using it on SunOS 5.8. I will appreciate if someone can help me out with this problem. Everytime I try to import a module in Python it gives me: ImportError: ld.so.1 python: fatal relocation error: ............ :referenced symbol not found. So, I tried following command. ldd -r libboost_python.so I have put part of the output of "ldd" command below. libstdc++.so.4 => /dq/local/gcc-3.1.1/lib/libstdc++.so.4 libm.so.1 => /usr/lib/libm.so.1 libgcc_s.so.1 => /dq/local/gcc-3.1.1/lib/libgcc_s.so.1 libc.so.1 => /usr/lib/libc.so.1 libdl.so.1 => /usr/lib/libdl.so.1 symbol not found: PyComplex_Type (./libboost_python.so) symbol not found: PyFloat_Type (./libboost_python.so) symbol not found: PyExc_StopIteration (./libboost_python.so) symbol not found: PyMethod_Type (./libboost_python.so) symbol not found: PyExc_IndexError (./libboost_python.so) symbol not found: PyExc_OverflowError (./libboost_python.so) symbol not found: PyInt_Type (./libboost_python.so) symbol not found: PyModule_Type (./libboost_python.so) Could someone please let me know how could I make these missing symbols available?I will greatly appreciate it if someone can help me with this problem. Thank you. Maulik
