ldd in Codesourcery Toolchain missing?

Gennadiy Kiryukhin

CodeSourcery Toolchain for ARM GNU/Linux EABI processors does not have ldd tool. Is there any other way to find out what libraries are required by a program?

Update:

In DM355 project, I have a root file system that has some basic libraries. I am trying to run some example programs on my board and the program complains that some libraries are not found. Is there an easy way to find the list of libraries that are required? If I need a library, where can I find it? Does the library have to be recompiled with the ARM CodeSourcery toolchain?

One suggestion to find the libraries needed is to use arm-none-linux-objdump. I just went into a root file system I have and did

arm-none-linux-gnueabi-objdump --all-headers libusb-0.1.so.4.4.4

and have this in some of the output

Dynamic Section:
NEEDED               libusb-1.0.so.0
NEEDED               librt.so.1
NEEDED               libgcc_s.so.1
NEEDED               libpthread.so.0
NEEDED               libc.so.6
SONAME               libusb-0.1.so.4

Thank you. It worked.

Then, here is a command line that someone may use to get the list of libraries needed.

arm-none-linux-gnueabi-objdump -x {filename} | grep "NEEDED"

It can be turned into a simple bash script.

#!/bin/bash
arm-none-linux-gnueabi-objdump -x $1 | grep "NEEDED"

Just give it the file name as a parameter and it will give you the list of libraries.
