AolServer and core dumps
|
|
| Agnieszka Kukałowicz 2007-03-28, 7:11 am |
| Hi,
I have question on how to force Aolserver to dump core?
My Aolserver crashes in some circumstances causing segmentation fault.
I would like to debug the problem, but I can't see any core file.
It looks like everything is set right.
I made 'ulimit -c unlimited' to have unlimited core file size and my
permissions where I dump a core look ok. What might be the reason it
does not work?
Cheers

a while back.

| Hi,=20
I tried to use it but it doesn't work.=20
It looks like something is wrong with tcl-coredumper configure script.=20
I did:
configure --with-tcl=3D[aolserver_dir]/lib
--with-google-coredumper=3D/usr/local
make
and put it under Aolserver lib directory.
When I had started to use it I got an error:=20
couldn't load file "[aolserver_dir]/lib/coredumper/coredumper.so":
libcoredumper.so.0: cannot open shared object file: No such file or
directory
while executing
"load [aolserver_dir]/lib/coredumper/coredumper.so"
("package ifneeded" script)
invoked from within
"package require google-coredumper 0.1"
And 'ldd coredumper.so' prints:
libtcl8.4.so =3D> /web/jail/opt/aolserver4/lib/libtcl8.4.so
(0x4000a000)
libdl.so.2 =3D> /lib/libdl.so.2 (0x400ab000)
libpthread.so.0 =3D> /lib/i686/libpthread.so.0 (0x400ae000)
libm.so.6 =3D> /lib/i686/libm.so.6 (0x400c2000)
libcoredumper.so.0 =3D> not found
libc.so.6 =3D> /lib/i686/libc.so.6 (0x42000000)
/lib/ld-linux.so.2 =3D> /lib/ld-linux.so.2 (0x80000000)
But the libcoredumper.so.0 is in the directory /usr/local:
ls /usr/local/lib/libcoredumper*:
/usr/local/lib/libcoredumper.a =20
/usr/local/lib/libcoredumper.so =20
/usr/local/lib/libcoredumper.so.0.0.0
/usr/local/lib/libcoredumper.la =20
/usr/local/lib/libcoredumper.so.0
How should it be configured?
Cheers

No, it's in /usr/local/lib. Is /usr/local/lib in your LD_LIBRARY_PATH?

My mistake. I've forgetten to make 'ldconfig' after installing
google-coredumper. After that everything is ok.
Thanks for help
