Hello, Enrico
2) in order to proceed, let's "align" our development environment in terms
of source code modifications. In fact, to build jchevm, just like you,
I had
to add some declarations in some header files, and modify the pread()
call into a read(). My proposal is the following:
let's install the new versions of Cygwin, Classpath, and jchevm,
build them from scratch, produce a written document with all the steps
and modifications, and post it this mailing list.
Afterwards, we will be able to write and debug some test cases.
what do you think?
I think that I already did this since started.. Just recorded all (or I
hope all) I did
Below is copy of my records....
Install Cygwin (
http://developer.classpath.org/mediation/ClasspathOnCygwin )
+ gcc-core
+ gcc-g++
+ gcc-java
+ make
+ zip
+ GTK
+ pkgconfig
+ autocofig
+ automake
+ libtool
(not sure that I recorded all optional packages I installed)
Download jikes from
http://prdownloads.sourceforge.net/jikes/jikes-1.22.tar.bz2?download

build jikes ( cygwin version )
-----------------
$ tar -xjf jikes-1.22.tar.bz2
$ cd jikes-1.22
$ ./configure
$ make && make install
Build Classpth-0.20
-----------------
$ ./configure --with-jikes --enable-gtk-peer --enable-jni
$ make
$install
Build JCHEVM
-----------------
$ ./configure --with-classpath=/usr/local/classpath
Add cache clean to autogen.sh before each call automake or autoconfig
--
rm -rf autom4te*.cache
echo "running automake"
....
rm -rf autom4te*.cache
echo "running autoconf"
