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
Apply this patch

build jikes ( cygwin version )
-----------------

$ 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

Hi Ivan,
ok, in order to double check these guidelines, I'll do the whole
build from scratch and see if they lead me to the point where you are now.
I'll have the time to do it tomorrow or wednsday, though.
In the mean time, could you try to: apply the latest Archie's patch,
enable the assertions,
and see where jchevm exits?
Enrico
