class lib. For anyone interested, below is the workarounds I used:
1)
Unzip /usr/local/classpath/share/classpath/glibj.zip to
/usr/local/unzipped_glibj
2)
Unzip ../jchevm/java/jc.zip to /usr/local/unzipped_jc
3)
In .../jchevm/libjc/native/Makefile, replace the line:
JAVAH_CMD = $(JAVA
Thanks, Archie.
After applaing your fix it no more crashes.
Just tested this with QuickSort algorithm. It's running OK. (but a bit
slow under cygwin in comparison to SUN's JVM under Win)
I will try some more sophisticated tests later.
Thanks again,
Ivan
Hello, Archie
This one is mysterious and will take some debugging by someone on
a Cygwin platform. I'd start by checking what "r" is (i.e., what's
the return value). Then try to come up with a simple test case
of a condition variable, etc.
As I can check
_r = 22 and vm->vm_destruction = 0
Archie, Ivan,
I am following the email that Ivan Snowdosker sent on Monday, Feb 20
that describes how to build and run JCHEVM. I have hit a couple of
bewildering snags. I installed the latest version of cygwin from the
net but there still seems to be build problems.
I need to build

Thank you. Succesfully merged your changes and now everything looks better..

Hello, Enrico.
great! I'll try it tomorrow on my PC.
I think there are still quite a few things to fix on Cygwin,
because, for example, if we enable the assertions, JCHEVM exits.
The results we've got are encouraging though :-)
Unfortunately some things to fix remains.
For the moment I just c

Finally HelloWorld is working!

Hi, Enrico.
Just figured out the roots of the problem. It comes from dlopen()
function on cygwin.
*JCHEVM* use the following code for loading native shared libraries
in \cygwin\home\ivan\jchevm\libjc\native_lib.c line:330
else if ((handle = dlopen(dlname, RTLD_NOW)) == NULL) {

are you saying that, even though the permissions of libjavanio.dll.a

Yes, I just set all x rights /usr/local/classpath/lib/classpath/

Many thanks, Enrico and Archie.
Finally I built JCHEVM.

Any ideas what does it mean?
I guess library linking problems. But have no ide
