Xapian devel - Aug 2015 - xapian 1.2.21 / MSYS-1.0.11.exe

Xapian Developers,

[I initially thought to install xapian on SFU (Interix 3.5) on MS XP but could
not compile libuuid]
[getopt.h, inttypes.h, and stdint.h taken from SUA (for Vista) and installed in
SFU (Interix 3.5)]

If someone is inclined to write a modified libuuid and label it for use with
Interix <version(s)> to
satisfy the dependency for an xapian <version(s)> install on Interix
<version(s)>, it might be of
interest, though since Windows 8.1 MS has discontinued enabling for SUA
(Interix).

Perl fails some tests from 'make test' in Interix 3.5.
Tcl configure scripts cannot figure out how to compile other than static
libraries on Interix 3.5.

xapian bindings for tcl (8.5.5 installed from source with MinGW/MSYS as below)
do not seem to be able to use tcl's .dll 

The argument --cxxflags returning empty when xapian was installed as
[MSYS-1.0.11.exe] /usr, from
g++ `xapian-config --cxxflags` quickstartindex.cc `xapian-config --libs` -o
quickstartindex, caused
me to rethink the install prefix, so I uninstalled it and reinstalled as
--prefix=/c/xapian.

I created a log of 'make check' which is
attached to this email as make.check.

Some additional comments below.

Best Regards,
Eric Lindblad

The similar to the above occurred when compiling quickstartsearch.cc.

Why did you decide to use interix?  My understanding was that it was
rather neglected, both by MS and everyone else.

If you're building with GCC (as you seem to be below), that should
just work (with either mingw or cygwin).

If you're wanting to build with MSVC, that worked fairly recently,
albeit with a different build system, but a change of build system
shouldn't require a POSIX emulation layer to be added into the mix.

Can you not just use the existing UUID code which makes use of the win32
UUID API?  See common/win32_uuid.{cc,h} for that.

There's an assumption that /usr/include is on the default compiler
header search path.  Explicitly specifying -I/usr/include breaks
"fixinclude" headers with some GCC versions - early 3.x IIRC, so
probably not a problem in practice these days, but perhaps it's
better to skip that test based on a platform check (under interix
in particular).

That's a generic C++ issue - quickstartindex.cc is missing a header:

#include <cstdlib>

We ought to just kill the quickstart examples though -
examples/simple*.cc are better minimal examples.

Me too - that was a contributed file, and AFAICS it can never have
actually worked correctly, so presumably the contributor failed to
even check it worked before sending in a patch.  Thanks for noticing
- fixing it git master, and I'll backport.

Cheers,
