why I can not run binary I am looking at in directory

[shahin]

I downloaded a copy of arm toolchain from a site called SourceyCode in the form of tar file, and after untaring the content I see the following in the bin directory readme file:

The executables in this directory are for internal use by the compiler
and may not operate correctly when used directly. This directory
should not be placed on your PATH. Instead, you should use the
executables in ../../bin/ and place that directory on your PATH.

I went to ../../bin/ and I found the file that I need, but I can not issue the command I want to run the assember. Please see below:
I am in the following directory:

@ubuntu:~/toolchains/arm-2014.05/arm-none-eabi/bin$ cd ../../bin
@ubuntu:~/toolchains/arm-2014.05/bin$ ls
add.s                    arm-none-eabi-g++         arm-none-eabi-nm
arm-none-eabi-addr2line  arm-none-eabi-gcc         arm-none-eabi-objcopy
arm-none-eabi-ar         arm-none-eabi-gcc-4.8.3   arm-none-eabi-objdump
arm-none-eabi-as         arm-none-eabi-gcc-ar      arm-none-eabi-ranlib
arm-none-eabi-c++        arm-none-eabi-gcc-nm      arm-none-eabi-readelf
arm-none-eabi-c++filt    arm-none-eabi-gcc-ranlib  arm-none-eabi-size
arm-none-eabi-cpp        arm-none-eabi-gcov        arm-none-eabi-strings
arm-none-eabi-cs         arm-none-eabi-gdb         arm-none-eabi-strip
arm-none-eabi-cs-daemon  arm-none-eabi-gprof       cache
arm-none-eabi-elfedit    arm-none-eabi-ld

And I am trying to issue:

 arm-none-eabi-as -o add.o add.s

But I get the following error:

 bash: /home/blahblah/toolchains/arm-2014.05/bin/arm-none-eabi-as: No such file or directory

Why can I not issue the above command?

Is it the correct binary type for your system? what does

file /home/blahblah/toolchains/arm-2014.05/bin/arm-none-eabi-as

say?

[shahin]

Thanks. I am following the instructions given here:http://www.bravegnu.org/gnu-eprog/hello-arm.html I am not sure what you mean by "what does it say". Is there a command you want me to run to findout more about it?

[steeldriver]

yes, please run the command exactly as I posted above - also please post whether your system is 32-bit or 64-bit

Frankly, so far this has been a very interesting project. Here is why. If you look below, I am sharing the directory structure of the package I downloaded and unziped:

From my home directory, I go into the unzipped package's bin directory, which does not have the assembler. But when I

 cd ../../bin/

I go in a directory, which I see the assembler binary. I do not know for the life of my where this directory is, or how else I can get to it. Maybe that is why the OS can not find it either.

Thanks. This may have solved the problem. The Ubuntu environment is a 64bit vm running on Winodows 7. The arm file a 32 bit file according to the output of the command you asked for:

blahblah@ubuntu:~/toolchains/arm-2014.05/bin$ file arm-none-eabi-as
arm-none-eabi-as: ELF 32-bit LSB  executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, stripped
blahblah@ubuntu:~/toolchains/arm-2014.05/bin$

The other potential issues I see is that the package was built for GNU linux. I figured since the commands look like Debian, I may be able to run the files on Ubuntu. Am I wrong you think?

[shahin]

This is still an outstanding question for me. Can anyone chime in? I looked online also; still don't know what is the problem with the code.

[shahin]

I found the answer to this; hope it helps someone else. I needed to install the 32bit libraries, which are:

lib32z1 lib32ncurses5 lib32bz2-1.0

I may have been able to getaway with just one of them also. I have to research it.
