[Swig-user] Errors Creating A Shared Library DLL for SWIG Packaged Simple Java Example (Windows)

[colin g. <cgs...@gm...>]

Hi All,

I've gone over the SWIG FAQ and dynamic module documentation and there
seems to be a wide array of options when deciding on how to build the JNI
shared library dll for Windows. The
wiki<http://www.dabeaz.com/cgi-bin/wiki.pl?SwigFaqDLLForWindows>
describes
the process using very old versions of visual c++. What is everyone using?

*I've installed MinGW and the below commands on Windows 7 and ran the below
commands on the SWIG simple java example, see below:*

   - C:\swig\swigwin-2.0.4\Examples\java\simple>swig -java example.i
   - C:\swig\swigwin-2.0.4\Examples\java\simple>gcc -c example_wrap.c -I
   C:\Program F iles\Java\jdk1.6.0_30\include -I C:\Program
   Files\Java\jdk1.6.0_30\include\win32
   - C:\swig\swigwin-2.0.4\Examples\java\simple>gcc -shared example_wrap.o
   -o example.dll

*Last command errors out with:*

example_wrap.o:example_wrap.c:(.text+0xa9): undefined reference to `gcd'
example_wrap.o:example_wrap.c:(.text+0xe2): undefined reference to `Foo'
example_wrap.o:example_wrap.c:(.text+0xe8): undefined reference to `Foo'
example_wrap.o:example_wrap.c:(.text+0x107): undefined reference to `Foo'
example_wrap.o:example_wrap.c:(.text+0x10d): undefined reference to `Foo'
