[Quantlib-users] Building QuantLib-SWIG for Java under Windows (with MSYS2) fails with "undefined reference to vtable for XYZ"

[<ara...@gm...>]

Hi all,



Thanks for taking the time to read this.



I'm trying to build QuantLib-SWIG for Java under Windows. Instead of Visual
Studio I'm using MSYS2 (which is based on Cygwin) for building.



The make command compiles the target quantlib_wrap.o successfully but then
fails at the target libQuantLibJNI.so with a ton of error messages like this
one:



C:/Users/christian/coding/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/1
1.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe:

quantlib_wrap.o:quantlib_wrap.:(.text$_ZN5boost10shared_ptrIN8QuantLib14Swap
RateHelperEEC1IS2_EEPT_[_ZN5boost10shared_ptrIN8QuantLib14SwapRateHelperEEC1
IS2_EEPT_]+0x2f):

undefined reference to `vtable for
boost::detail::sp_counted_impl_p<QuantLib::SwapRateHelper>'



The versions are:

QuantLib 1.24

QuantLib-SWIG 1.24

Boost 1.77.0 (pre-compiled binaries)



I ran the build of QuantLib-SWIG with the following commands and parameters:



$ ./configure --with-jdk-include="/c/Users/christian/coding/jdk-15/include"
--with-jdk-system-include="/c/Users/christian/coding/jdk-15/include/win32"

$ make -C Java



The failing build step is: g++ -g -O2  -shared quantlib_wrap.o -o
libQuantLibJNI.so `quantlib-config --libs`

The command quantlib-config --libs gives: -L/mingw64/lib
-L/c/Users/christian/coding/boost_1_77_0/lib64-msvc-14.1 -lQuantLib

The directory /mingw64/lib contains the previously compiled files
libQuantLib.a and libQuantLib.la



The build of QuantLib itself was successful. I ran it with the following
commands and parameters:



$ ./configure --enable-intraday
--with-boost-lib=/c/Users/christian/coding/boost_1_77_0/lib64-msvc-14.1
--with-boost-include=/c/Users/christian/coding/boost_1_77_0

$ make

$ make install



Any help would be highly appreciated.



Regards,

Christian
