[redland-dev] Rasqal 0.9.29 problems with configure under mingw (MXE)

[info at mycontent.gr]

Dear all,

I am trying to cross-compile Rasqal 0.9.29 using mingw32 and the M Cross
Environment (mxe.cc) under Ubuntu LTS 12.04.
The MXE already provides PCRE, libgcrypt and libxml2. I have successfully
compiled Raptor 2.0.8 and installed it under the mingw32 tree.
The ultimate goal is to cross-compile Sonic Visualiser 2.0 for Windows
(which needs Redland, which needs Rasqal, which needs Raptor) and hopefully
use this experience to propose MXE packages for the three Redland libraries
(to help others who might want to cross-compile them for Windows). As a side
note, I've successfully compiled Raptor, Rasqal and Redland (and Sonic
Visualiser) under Linux. 

I've been running into three problems:
1. The ./configure script does not find PCRE and libgcrypt automatically. It
also igonres the --with-pcre-config, --with-libgcrypt-config options
("unrecognized options").
2. The ./configure script fails "checking for ceil, floor and round". As a
temporary workaround, I've commented out lines 15274,5,6 of the script (the
ones that make it fail upon encoutering this error). This allows configure
to complete, but doesn't seem to be the right solution... anyway, we didn't
get too far:
3. Make fails because 'struct timezone' (which is defined in time.h) is
redefined in win32_rasqal_config.h.

The command I've used to configure Rasqal is:
    ./configure --host=i686-pc-mingw32 --prefix=/opt/mxe/usr/i686-pc-mingw32
\
                --with-sysroot=/opt/mxe/usr/i686-pc-mingw32/bin/ \
 
--with-pcre-config=/opt/mxe/usr/i686-pc-mingw32/bin/pcre-config \
 
--with-libgcrypt-config=/opt/mxe/usr/i686-pc-mingw32/bin/libgcrypt-config \
 
--with-xml2-config=/opt/mxe/usr/i686-pc-mingw32/bin/xml2-config \
                --with-decimal=none --enable-query-languages=sparql \
                --enable-static --disable-shared \
                PKG_CONFIG=/opt/mxe/usr/bin/i686-pc-mingw32-pkg-config

I'm attaching the detailed output (rasqal_compile_problems.txt).

Any ideas and help would be greatly appreciated!

Regards,
George Christodoulides
