pt-raise.c: No such file or directory

[Mahmood Naderan]

Hello,
Using Ubuntu-64bit, when I attach GDB to a process, I see these messages

...
Reading symbols from /usr/lib/x86_64-linux-gnu/libstdc++.so.6...(no debugging symbols found)...done.
Loaded symbols for /usr/lib/x86_64-linux-gnu/libstdc++.so.6
0x00007f72e111eb7b in raise (sig=<optimized out>) at ../nptl/sysdeps/unix/sysv/linux/pt-raise.c:42
42      ../nptl/sysdeps/unix/sysv/linux/pt-raise.c: No such file or directory.
(gdb)


On another system which runs Centos-64bit, I don't see such messages. Any way to fix that?

 
Regards,
Mahmood

BTW
(gdb) set filename-display absolute
would should you the exact location of that file.

CentOS glibc-debuginfo.rpm contains file:

$ ls -l /usr/src/debug/*/nptl/sysdeps/unix/sysv/linux/pt-raise.c
-rw-r--r-- 1 root root 1728 May 4 2010 /usr/src/debug/glibc-2.12-2-gc4ccff1/nptl/sysdeps/unix/sysv/linux/pt-raise.c

Bugreport it to Ubuntu; but the same problem affects also underlying Debian.

See this output

Also there is no such file on the system.

Any more idea? BTW, is that a warning or error? Does that have ay effect on debugging process?

No symbol "filename" in current context.

You have too old GDB, "set filename-display" exists since GDB-7.6.

It is an "issue" of Debian/Ubuntu packaging. Debian/Ubuntu prefers smaller
debug info packages but the disadvantage is the missing source files.

It only does not display the source. Otherwise it has no effect.

Thanks. I installed GDB-7.7 from source with "./configure && make && make install" and the message disappears

You need to install the dbg package.
