In /usr/i686-pc-mingw32/xslt_xml2/bin? If not, you'll need to add the path to the dll to PATH or move the dll to this xslt_xml2/bin directory. > I believe it works for WinXP because I saw the msg on the website: > "The binaries are supported on an operating system based on the NT-kernel, > such as Windows NT, Windows 2000 and Windows XP, exclusively" > > also it seems require iconv, which we don't really need. > libxslt requires it. > anyway, we decide to compile it ourselves, here are the changes I did: > You'll need the patches I just submitted to this list. > 0. for windows, makefile and configure are under /win32, run configure > like Readme.txt sugguests: > I believe you'll need to specify the --host switch if you're using Cygwin. > cscript configure.js threads:no static:yes compiler:mingw iconv:no > prefix=where_you_want_to_install include=where_your_mingw_include_is > lib=where_your_mingw_lib_is debug=yes > > 1.

Without my patch xmlcatalog will fail to read the entries in the catalog if you use GCC-4.6.1. All I needed to do with MinGW + MSYS otherwise was cd libxml2-2.7.8 mkdir bld cd bld ../configure --prefix=/mingw --without-python --enable-shared --disable-static make make install I've also built it with the python bindings but you must ensure that your environment is set up with PYTHON variables. -- Earnie -- https://sites.google.com/site/earnieboyd/ _______________________________________________ xml mailing list, project page http://xmlsoft.org/ xml@gnome.org http://mail.gnome.org/mailman/listinfo/xml
