Hi, I've managed to compile PPL to a windows dll along with java interface using MinGW. I will describe how I achieved this step by step. First thing was to build the ppl library (not java interface) to a dll. I found out that to do this AC_LIBTOOL_WIN32_DLL must be added to autoconf along with '-no-undefined' to LDFLAGS (see http://sourceware.org/autobook/autobook/autobook_254.html ). I also based this on gmp's autoconf file. Patch is available in attached patch.configure.ac file (running autoconf is needed to create configure file). To compile ppl to a dll you need to run configure with parameters: "--disable-static --enable-shared".
I didn't manage to compile ppl dll to use static gmp library version. I compiled gmp as a shared library (configure --enable-cxx --disable-static --enable-shared). Unfortunately make check fails when gmp is compiled like this - but it seems the library works ok. After compiling gmp I made copy of libgmp.dll.a as libgmp.a and libgmpxx.dll.a to libgmpxx.a so that PPL can be linked to it (possibly there is another solution).
Later I had to compile the Java library (add --enable-interfaces=java, to configure arguments). I had some problems with configuring java path (--with-java=DIR) this is because I use the 64 bit windows system - java is installed in "C:\Program Files (x86)\Java\jdk1.6.0_17". (i passed --with-java="/c/Program Files (x86)/Java/jdk1.6.0_17") I had to manually update makefiles for java interface because javah was not properly found, includes were not properly generated (there was "-I/c/Program Files (x86)/Java/jdk1.6.0_17/include/mingw" instead of "-I/c/Program Files (x86)/Java/jdk1.6.0_17/include/win32") and had manually fix java directory issues (add "'s). Another important thing was to modify Makefile for the jni dll file (interfaces/Java/jni) (see http://www.mingw.org/node/41 ) - add " -D_JNI_IMPLEMENTATION_ -Wl,--kill-at" flags to libppl_java_la_LDFLAGS. After these modifications the dll was successfully build.
PS. Also I'm not sure when the jni compilation flags should be added (gcc and windows machines?) and I'm not autoconf expert - this hopefully could be automatized.
