Hello,

When I  connect to analyzer on a x86_64 processor(with Roody),  
a analyzer break with segmentation violation in the root_server_thread  function.
Same code are working fine on a 32bit processor.
As I found the problem are in exchanging of pointers between analyzer and client.
Before to send a pointer, it is saved a pointer in int (size=4, instead of 8) at
this place:

Yes right, Problem of a segmentation violation is solved with this patch. Now it works
fine on x86_64.

I add the following to makefile and try to treat Darwin as FreeBSD/Linux.
But I failed.

Could anyone give me some hints. Thanks!

I cannot checkout module:

I know the original CGI script has such a feature. Thanks.

Thanks a lot. But I cannot checkout module:

P.S.
I use these commands to checkout:
   cvs -e ssh -d :ext:cvs@midas.psi.ch:/usr/local/cvsroot checkout midas
   cvs -e ssh -d :ext:cvs@midas.psi.ch:/usr/local/cvsroot update

Unfortunately, I still encounter the same problem.

pc2075.psi.ch: Operation timed out
cvs [checkout aborted]: end of file from server (consult above messages if any)

I am in LNS-INFN (Italy), i.e., I am outside PSI. So ... what's the problem? I try to
ping the host, and it is reachable:
--------
[exaos@exaos cvsnew]$ ping midas.psi.ch

...
--------
Is it the problem of firewall? I am not sure. So strange.

Waiting for the new release ...

I cannot checkout from the cvs server. So I download each latest file from the WWW
interface of CVS. While compiling these files, I encountered the following problems:

---------------
What does '-rpath' mean? It is just a linking error. Thanks.

I have compiled the sources on Darwin 7.4.0 with gcc 3.3. After the compilation of source codes, I 
try to execute "gmake install". I got the following message:
-------
Nothing to be done for "install".
-------

The install target could not be executed. Then I add the following line to the Makefile:
------
.PHONY: install
------

The install target can be executed. But when it is tring to copy "dio" to the proper directory, it 
cannot find the file. Then I found that the "utils" target isn't built. 
I try to build the target: darwin/bin/dio, I got the following error:
-------
cc -g -O2 -Wall -Iinclude -Idrivers -Ldarwin/lib -DINCLUDE_FTPLIB   -DOS_LINUX -DOS_DARWIN 
-DHAVE_STRLCPY -fPIC -Wno-unused-function -o darwin/bin/dio utils/dio.c
utils/dio.c:39:20: sys/io.h: No such file or directory
utils/dio.c: In function `main':
utils/dio.c:46: warning: implicit declaration of function `iopl'
gmake: *** [darwin/bin/dio] Error 1
--------
So, the include file "sys/io.h" may be changed under Darwin. I don't know how. I will try later. I 
hope somebody can notice this. 
Best regards.

There are not such a file "io.h" inside my MacOS X. In fact, I didn't find any file containing function iopl().
So what is the equivalent function of iopl() under MacOS X? The utility dio should be modified in order to be compiled under Darwin-
gcc platform.

While executing "make install" under MacOS 10.4.7, you may encounter errors about "dio". It is the 
problem of "Makefile". I did some change to it and attach the diff file here.

I rewrote the Makefile for MIDAS in order to make it tidy. I tested it on my box
and it works here.
1. The full file is seperated to several parts
  a. initialized setup
  b. environment setup
  c. specify OS-specific flags
  d. processing environment for building flags
  e. targets
2. The file is less than 400 lines now. The original one is more than 500 lines.
3. The modified one is easy for debuging.

I tried to learn "autoconf" and "automake" in order to make building MIDAS more
compatible for various platforms. But I havn't enough time now. Hope somebody
can help it. The attached file is original named "Makefile.in" for using "autoconf".
