I am releatively new to Solaris and I am the System administrator for my branch at the FAA. This is the first time I can say I have really messed something up thankfully. My issue came up after installing and uninstalling Oracle Secure Backup which i felt I needed to do a clean reinstall due to inability to find scsi devices. After doing so I realized that I could no longer run the ./installob script it would throw the following error...and I have no knowledge or understandinf of the runtime linker and ELF classes...etc...
after messing around with the LD_LIBRARY_PATH env variable I realized I messed something else up I can no longer run "ldd" command it says the following
Now regardless what i run, if it has to do with the ld.so.1 runtime linker then it throws a similar error every time. There are even a couple services I cannot get to start like efdaemon, sma, webconsole and oplhpd.
I realize this may be considered a remedial question for this forum but any help would be greatly appreciated.
Thank You,
Jerry

using SUN C++ I have a problem when I do a push_back on a vector. The linker gives me a undefined symbol error on __cxa_end_catch.
Any ideas, is there a library to include?

Hi, I want to define a symbol in my code as:
extern int Address;
and then I'd like to define the symbol value in linker (ld) script file, so each time I change the hardware, I don't need to redefine the value in code, just use different linker script. I've gone through ld reference and didn't... (3 Replies)

Hi,
The necessary symbols in a shared library can be exported to the application using linker option --version-script in Linux. The same can be done in Hp-ux using linker option +e. This can also be done by listing all the global symbols with +e in a file with linker option ld -c filename in... (0 Replies)
Hi Perl folks,

I wish to push elements into array at runtime and the print it later.
Now I wish to print this matrix using colors.

ldd
LDD(1) Linux Programmer's Manual LDD(1)NAME
ldd - print shared object dependencies
SYNOPSIS
ldd [option]... file...
DESCRIPTION
ldd prints the shared objects (shared libraries) required by each program or shared object specified on the command line. An example of
its use and output is the following:
$ ldd /bin/ls
linux-vdso.so.1 (0x00007ffcc3563000)
libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f87e5459000)
libcap.so.2 => /lib64/libcap.so.2 (0x00007f87e5254000)
libc.so.6 => /lib64/libc.so.6 (0x00007f87e4e92000)
libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f87e4c22000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f87e4a1e000)
/lib64/ld-linux-x86-64.so.2 (0x00005574bf12e000)
libattr.so.1 => /lib64/libattr.so.1 (0x00007f87e4817000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f87e45fa000)
In the usual case, ldd invokes the standard dynamic linker (see ld.so(8)) with the LD_TRACE_LOADED_OBJECTS environment variable set to 1.
This causes the dynamic linker to inspect the program's dynamic dependencies, and find (according to the rules described in ld.so(8)) and
load the objects that satisfy those dependencies. For each dependency, ldd displays the location of the matching object and the (hexadeci-
mal) address at which it is loaded. (The linux-vdso and ld-linux shared dependencies are special; see vdso(7) and ld.so(8).)
Security
Be aware that in some circumstances (e.g., where the program specifies an ELF interpreter other than ld-linux.so), some versions of ldd may
attempt to obtain the dependency information by attempting to directly execute the program, which may lead to the execution of whatever
code is defined in the program's ELF interpreter, and perhaps to execution of the program itself. (In glibc versions before 2.27, the
upstream ldd implementation did this for example, although most distributions provided a modified version that did not.)
Thus, you should never employ ldd on an untrusted executable, since this may result in the execution of arbitrary code. A safer alterna-
tive when dealing with untrusted executables is:
$ objdump -p /path/to/program | grep NEEDED
Note, however, that this alternative shows only the direct dependencies of the executable, while ldd shows the entire dependency tree of
the executable.
OPTIONS --version
Print the version number of ldd.
-v, --verbose
Print all information, including, for example, symbol versioning information.
-u, --unused
Print unused direct dependencies. (Since glibc 2.3.4.)
-d, --data-relocs
Perform relocations and report any missing objects (ELF only).
-r, --function-relocs
Perform relocations for both data objects and functions, and report any missing objects or functions (ELF only).
--help Usage information.
BUGS
ldd does not work on a.out shared libraries.
ldd does not work with some extremely old a.out programs which were built before ldd support was added to the compiler releases. If you
use ldd on one of these programs, the program will attempt to run with argc = 0 and the results will be unpredictable.
