Re: [Quantlib-dev] Help! Quantlib Java SWIG build issue

[Banerjee, T. K <tap...@jp...>]

Hi Luigi,

Thanks for your response . I set  LD_LIBRARY_PATH  before.
Again tried, but no luck. (See below).

Can version of library , g++/Linux cause this issue?  Any other ideas I can try?
I am using QuantLib-SWIG-1.15, QuantLib--1.15, boost_1_68_0, gcc version 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC)

bash-4.1$ LD_LIBRARY_PATH=/home/v574933/quantlib/qlib/lib
bash-4.1$ export LD_LIBRARY_PATH
bash-4.1$ echo $LD_LIBRARY_PATH

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/v574933/quantlib/qlib/lib/libQuantLibJNI.so: /home/v574933/quantlib/qlib/lib/libQuantLibJNI.so: undefined symbol: _ZNK8QuantLib13TermStructure13referenceDateEv

Try setting the environment variable LD_LIBRARY_PATH to <base-dir>/quantlib/qlib/lib

But while running example file, I am getting below error.. Any idea - what I am doing wrong and how to fix?
