[Xapian-devel] Trying to get Search::Xapian perl module to compile on win32

[Desmond Daignault]

Resurrecting an old thread from 2012!  Finally got back to working on this.  I have been stuck in JavaScript land for too long.

Come to find out, on windows, perl does indeed define open to be win32_open and close to be win32_close.  This is done in perl/lib/CORE/win3iop.h.  So, to get past this problem, I had to modify Xapian.xs to do an #undef of open and close if WIN32 is defined.

Also, I had to modify the Makefile.PL to not use xapian_config to get the values it needs. 

Attached is a work in progress patch for both files.  (hope the attachments come through)  I am now getting linking errors.  I am working with the latest stable version of xapian-core, which I cross-compiled on Ubuntu for win32.  I had to do a couple of manual steps to convert the libxapian-22.dll into a libxapian-22.lib using info from https://support.microsoft.com/en-us/kb/131313.  Specifically using dumpbin /exports to create a definition file and then feeding the definition file to lib /def to create the .lib and .exp files.

The call to generate the Makefile on win32 is now something like: 
    perl Makefile.PL CXX=cl.exe INC=-IC:\Install\include " LIBS=-lxapian-22 -lzlib" XAPIAN_VERSION=1.2.21 "CXXFLAGS=-EHsc -TP"
	
Now when I run nmake, it gets past the compile portion and dies when linking with errors like: 
Xapian.obj : error LNK2001: unresolved external symbol "public: __thiscall Xapian::WritableDatabase:
:WritableDatabase(class Xapian::WritableDatabase const &)" (??0WritableDatabase at Xapian@@QAE at ABV01@@Z)

Any clues on how to resolve the linking errors?

Sounds to me like something is playing macro games along the lines of:

#define open win32_open
#define close win32_close

And that is mangling the method names in our code.

I don't use windows, but I can tell you it isn't anything in Xapian
doing this.
