thx satinz
I wait for the other user to provide their output-strace too.
The libraries are a useful to fix issues on few boxes, most users doesn't need my libs to make things work fair... I have added them for completeness.
@spiralvoice
do you think that substituting this c-code could suffice?:
| Code: |
/*******************************************************************
os_uname
*******************************************************************/
#ifdef HAVE_SYS_UTSNAME_H
#include <sys>
void os_uname(char buf[])
{
struct utsname uts;
if (uname (&uts) < 0)
{
sprintf(buf, "none none none none none");
}else
{
sprintf(buf, "%s %s %s %s %s",
uts.sysname, uts.nodename, uts.release, uts.version, uts.machine);
}
}
|
I have done few C-programs in my eary years but my C-skills are a bit rusty. 
Ps.
@spiralvoice, a detail , applying your patch I have got a error, then I have applied the patch "manually" directly on last CVS code.Perhaps I have done something wrong. perhaps it is better to directly send me the patch file the next time? I suppose you have got my email address.
I have used patch -p0 -E -i ... as usual

I do not know C.
Just compile a core with it and let users test it.

Thats the way to go in this case because I copied the patch from the diff
output in my terminal window directly into the forum editor.
No patch file here  because its a dirty hack to prove a theory.
In this state the patch will never make it into CVS.

ok, my modification stops this code from accessing unallocated space, it doesn't stop from invoke the uname command.PLus I don't create an exception but simply use the output (eroor state) to provide a default dummy result instead of accessing a non initialized(or allocated) structure.
I suppose that I have to apply my patch on a clean CVS.
I'll post a new core in few minutes.
@synology users, try both the past with spiralvoice patch and the new one with my patch...I'm going to provide it in one hour.

I have a compilation problem, I have to fix my code I think my version 'll be out tomorrow.

Parallel to fabtars core building efforts would it be a good idea to try
to build MLDonkey on the Synology machine yourself.
Is it based on a popular distro, like Debian?

Hi,
What is it based on a Debian like? Are you talking about the Synology Operating System? I strickly no idea. But even if it was the case, there is no compilation tools to build any applcation.
The tools deployed into the Synology are the BusyBox.

Yes, done. But same issue as Satinz.

ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40015000

write(3, "strace: exec: Exec format error\n", 32strace: exec: Exec format error
) = 32
close(3) = 0
munmap(0x40015000, 4096) = 0

Please call the MLDonkey binary directly with strace, not a shell script

The same as yesturday.
execve("./mlnet", ["./mlnet"], [/* 14 vars */]) = 0
uname({sys="Linux", node="DiskStation", ...}) = 0
--- SIGILL (Illegal instruction) @ 0 (0) ---

Does this mean uname has returned the 0 value?
It seems uname has worked properly.Perhaps it is something which happens just after that..
I have updated my code:
| Code: | void os_uname(char buf[])
{
struct utsname uts;
if (uname(&uts)<0)
sprintf(buf, "none none none none none");
else
sprintf(buf, "%s %s %s %s %s",
uts.sysname, uts.nodename, uts.release, uts.version, uts.machine);
} |
and I'm going to compile but I think that this is not going to solve the issue too.

this is my strace (working core ARM):
| Code: | execve("./mlnet", ["./mlnet"], [/* 17 vars */]) = 0
uname({sys="Linux", node="armguy", ...}) = 0
getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0
setrlimit(RLIMIT_STACK, {rlim_cur=2044*1024, rlim_max=RLIM_INFINITY}) = 0
getpid() = 3456
rt_sigaction(SIGRTMIN, {0x2cf88c, [], 0x4000000 /* SA_??? */}, NULL, 8) = 0
rt_sigaction(SIGRT_1, {0x2d0110, [RTMIN], 0x4000000 /* SA_??? */}, NULL, 8) = 0
rt_sigaction(SIGRT_2, {0x2cf190, [], 0x4000000 /* SA_??? */}, NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [RTMIN], NULL, 8) = 0
rt_sigprocmask(SIG_UNBLOCK, [RT_1], NULL, 8) = 0
brk(0) = 0x57c000
brk(0x59d000) = 0x59d000
mmap2(NULL, 253952, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40000000
brk(0x5bf000) = 0x5bf000 |
the next operation is :
getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0
but I fear that this is only a system call, the illegal could instruction be anywhere(?)

Could be useful?

I had been thinking of building mldonkey on the box too...
But I really have no idea where to start with regards to setting up a build environment.
I know Synology provides a cross-compilation platform, but I guess I shouldn't be cross compiling here. Any ideas about how to setup a build environment? |

perhaps you can try building directly on your box, it could be long but easier than a cross-compiling stuff.
I don't know if your box provides basic compilation -enviroment gcc.. perhaps you have to look at provided packages.
You have to install gcc - g++ and other tools like make and autoconf..
Then you can compile an ocaml enviroment, and then you can compile mldonkey.
But I don't know so much about your box, it is better that you get tips about in synology forum, the get back here when you have all the bascis to start compiling ocaml->mldonkey.I'll surely help you.
what do you need?
Look at:
