compiling JCHEVM with GCC/Cygwin
Hello Enrico
I'm trying to build JCHEVM following your steps described at
http://www.mail-archive.com/harmony-dev@incubator.apache.org/msg03212.html
I was able to build Classpath sucsesfuly, but
fail making JCHEVM
In result I have
native/java_lang_VMThread.c: In function `JCNI_java_lang_VMThread_start':
native/java_lang_VMThread.c:388: warning: implicit declaration of
function `pthread_attr_setstackaddr'
native/java_lang_VMThread.c:388: warning: nested extern declaration of
`pthread_attr_setstackaddr'
make[2]: *** [java_lang_VMThread.o] Error 1
make[2]: Leaving directory `/home/ivan/jchevm/libjc'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/ivan/jchevm/libjc'
make: *** [all-recursive] Error 1
Can you help me, please.
Thanks, Ivan

This assertion is there because we align the start of an object
with the first reference (which is in front of the object header).
The fix for this is to modify the code to align non-array objects
on 8 byte boundaries even if they have an odd number of reference words
(yuck). This requires changing the algorithm for determining object
size and heap block size, as well as "skip word" handling, etc.
(blah blah gnarly internals).
However, I'm curious why double alignment is 8 under Cygwin but
only 4 under Linux but both are x86. Obviously that can't derive
only from the hardware.
So for now I'd say just comment out that assertion and proceed.
If you get funny floating point results then we'll know why :-)

Yes, I just set all x rights /usr/local/classpath/lib/classpath/
on all files in and up directory tree (on winXP logged with full admin
rights)
$ ls -l /usr/local/classpath/lib/classpath/

Any thougths?
May be the problem is in *.dll.a extension so under win it's not treated
as executable?

Hi Ivan,
are you saying that, even though the permissions of libjavanio.dll.a are
-r-xr-xr-x,
you got the same message? Please, let me know.
If so, then I think we have to ask for help in the Classpath mailing list,
because I really got no clue :-)
--------------------------------------------------------------------------------
In the mean time, I'm studying the JCHEVM source code, in order to
figure out:
1. JCHEVM' OS dependancies
2. the way JCHEVM access the Classpath library
The study would much easies if I could use the debugger, and I think I'm
gonna
have to set up a Linux machine.

Thank you Enrico and Archie.
So now with assertions disabled I faced next problem, Enrico mentioned
in his email.
The same
"failed to open native library
/usr/local/classpath/lib/classpath/libjavanio.dll.a: permission denied"
I'm trying to run it under XP professional so I had no problem to set
exec flags in permissions
but this do not help.
Still the same problem.
Please, let me know if you will find solution.
Thanks, Ivan

Hi Ivan,
try this, in the autogen.sh file:
CONFIGFLAGS=" --disable-assertions"
After disabling the assertions, you should be face the same problem
where I'm currently stuck at:
http://cygwin.com/ml/cygwin/2006-02/msg00570.html
That problem, I think, should disappear on a WindowsXP Professional Edition.
Let me know how it goes.

Hi, Enrico.
Thank you for your help.
Looks like I am following you step by step and now have the same error
which you discussed with Archie few days ago =)
assertion failure 1
-----------------
vm.c - line 46
message = "assertion failure: _JC_FULL_ALIGNMENT <= (sizeof(_jc_word))"
When I add the following:
printf("_JC_FULL_ALIGNMENT=%u\n", _JC_FULL_ALIGNMENT);
jchevm prints: 8
But unfortunately this mail-list do not contain solution for it.
I can not figure out how to solve it. Can you help me, please?

Hi Ivan,
I got the same error two weeks ago :-)
To fix the problem, do the following things:
1) open the following file:
jc_invoke.c
2) find the following declaration:
static const struct poptOption jc_popt_options[] = {
3) remove the following line:
POPT_AUTOHELP
Afterwards, compile a HelloWorld.java class with any compiler,
and run: $jc HelloWorld

Many thanks, Enrico and Archie.
Finally I built JCHEVM.
This two jcjavah.exe and cfdump.exe printout help text when started, but jc.exe fail with message
"The application failed to initialize properly (0xc0000005)".
Any ideas what does it mean?
I guess library linking problems. But have no ideas which one cause it.
Thanks, Ivan

Hi Ivan,
it seems to me that what stops your compilation task is a warning,
treated as an error.
Try to build JCHEVM without --enable-werror
1. Open the following file:
autogen.sh
2. Replace the following line:
CONFIGFLAGS="--enable-werror --disable-assertions"
with this one
CONFIGFLAGS=" --disable-assertions"
3. Run again autogen.sh from the Cygwin shell
Note that you will need the following macro:
#define _JC_LIBRARY_FMT "lib%s.dll.a"
once you've built JCHEVM.

Hi Enrico,
This trik doesn't work :(
I changed .\libjc\arch\arch_definitions.h as you say but in result I
have the same

Hi Ivan,
if you're building JCHEVM with Cygwin, modify the following file:
.\libjc\arch\arch_definitions.h
at line 95.
Remove:
#define _JC_LIBRARY_FMT "lib%s.so"
Add:
#define _JC_LIBRARY_FMT "lib%s.dll.a"
In order to achieve a successfull build, I had to change a few other things.
Before I post them here, let's see how it goes your build.
Are you using a Home or a Professional Windows edition?

You can workaround the lack of pthread support in cygwin by defining
_JC_NO_THREAD_ATTRIBUTES at the top of that file.
