Have You failed in order to "make" the executable or has the "./configure" phase failed?
In case you have succesfully done the ./configure of mldonkey, can you redirect configure output to a file and send it to me(with rapidshare)?
I suppose that such output could contain valuable informrations on your synology enviroment, libraires and features.
| Code: |
./configure > configureoutput.txt

Ok, here's my first results. Not very uplifting 
Core - w/o libs:
| Code: | GH4NAS> ./mlnet
Illegal instruction (core dumped) |
core - w/o libs, w/ strace:
| Code: | GH4NAS> strace ./mlnet
execve("./mlnet", ["./mlnet"], [/* 14 vars */]) = 0
uname({sys="Linux", node="GH4NAS", ...}) = 0
--- SIGILL (Illegal instruction) @ 0 (0) ---
+++ killed by SIGILL (core dumped) +++ |
core - w/ libs:
| Code: | GH4NAS> ./mlnet2.sh
Illegal instruction (core dumped) |
So basically no change at all.

The idea of my uname patch was to remove the uname calls shown by strace.
Unfortunately this did not work because Ocaml itself calls uname()
in Unix.gethostname and again by its own VM used to start all
Ocaml programs. I even tried more patches, also to Ocaml, but
I did not succeed in eliminating the uname call on MLdonkey startup.

@Spiral
I have a doubt, I have read that the strace output is:
| Code: | | uname({sys="Linux", node="GH4NAS", ...}) = 0 |
do this mean that uname is succesfull?
Could the problem is related to an instruction which is after the uname call and just fist of rlimit call(next sys call)?
Or, is this "return value" unrelated and could uname be effectively the problem?
I really like to understand these details(I'm trying to raise my programmin' skills).

Can you do a gdb backtrace using the core file?

@fabtar: I have failed to see your post about make / configure. I don't have the setup right now, but I'll try to give it a go when I can find some time.
@spiralvoice: I dunno if it was targetted at me, but I tried gdb on the core file:

"/volume1/@mlnet.core": not in executable format: File format not recognized
(gdb) |
I don't know gdb well enough to determine if that's just due to bad setup, but to me it looks like I can't get any further with gdb.
EDIT: I don't know if this gives any futher info:

Hi , I have received and interestng mail from ma2xfr:
| Quote: |
Some guys, from my french Synology community, try to
install Linux on a Synology 207+ and get as well the
Illegale instruction...
Here the original link:
http://www.nas-forum.com/forum/index.php?showtopic=3910
This topic talks about the Synology ARM achitecture,
to install Linux as Chroot.
I translated this from this topic:
--------
1. EABI is not an architecture, it is just a way to
call functions.
2. You need a kernel compiled for supporting EABI for
this works.
3. The Synology Marvel Kernel is not a EABI
4. The illegal instruction comes from the fact that
the NPTL is missing in the Kernel
To conclude, if we do not have a Kernel compiled for
supporting EABI, we cannot use EABI to install Linux
and this is true with the recent CodeSourcery gcc. |
It looks like the problem is a lacking kernel feature.

I'm tryng to understand this abi-eabi stuff.
I cannot understand if the kernel lacks EABI feature or if the kernel lacks OLDABI support.
....
I hope someone 'll emerge from the wasteland with a solution.
So I Sleep() waiting.
Cheers

mmhh, by searching around I have found that Ocaml is not so EABI ready and QEMU seems not to work in EABI flawor.
So I'm compiling no-EABI and you need a no-eabi kernel and libraries or a kernel with oldabi support? This is my last hypotesis for the moment.
I have not the knowledges in order to go deeper into this.

Any "real support" from Synology ??
Well, hopefully you will work it out.
