Execute program

[vamitrou]

Hi,

I need to use a tool for a university homework. My problem is that the package contains 4 executables :
stanv3.linux,
stanv3s.linux,
stanv3.sparc,
stanv3s.sparc

You can find the files here:
planning.cis.strath.ac.uk/ STAN/ code/ stan.v3.tar.gz

In my ubuntu enviroment, the last two seem green (executable) when i use ls command, but the first two (the ones that i actually need) not.

I used chmod but i still can not run those files.

Does anyone have any clue?

Thanks in advace!

hi,
we dont answer homework questions here, but you are not there yet.

What is the output of:

ls -la stanv3*
file stanv3*

Hi, thanks for you reply.

Here is my output:

laptop@laptop-VGN-FW21M:~/Desktop/planner/STAN.V3$ ls -la stanv3*
-rw-r--r-- 1 laptop laptop 186440 1999-01-06 12:37 stanv3.linux
-rw-r--r-- 1 laptop laptop 258096 1999-01-06 12:37 stanv3s.linux
-rwxr-xr-x 1 laptop laptop 251824 1999-01-06 12:36 stanv3.sparc
-rwxr-xr-x 1 laptop laptop 323792 1999-01-06 12:37 stanv3s.sparc

and:

laptop@laptop-VGN-FW21M:~/Desktop/lanner/STAN.V3$ file stanv3*
stanv3.linux:  ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped
stanv3s.linux: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped
stanv3.sparc:  ELF 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically linked (uses shared libs), stripped
stanv3s.sparc: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically linked (uses shared libs), stripped

ok, the x-bits are missing.
This should fix it:

chmod 755 stanv3.linux stanv3s.linux

You can call executeables outside $PATH by giving the path.
Either of these should work

cd ~/Desktop/planner/STAN.V3
./stanv3.linux

or
~/Desktop/planner/STAN.V3/stanv3.linux

I tried it before but:

laptop@laptop-VGN-FW21M:~/Desktop/planner/STAN.V3$ ls -la stanv3*
-rwxr-xr-x 1 laptop laptop 186440 1999-01-06 12:37 stanv3.linux
-rwxr-xr-x 1 laptop laptop 258096 1999-01-06 12:37 stanv3s.linux
-rwxr-xr-x 1 laptop laptop 251824 1999-01-06 12:36 stanv3.sparc
-rwxr-xr-x 1 laptop laptop 323792 1999-01-06 12:37 stanv3s.sparc

laptop@laptop-VGN-FW21M:~/Desktop/planner/STAN.V3$ ./stanv3.linux 
bash: ./stanv3.linux: No such file or directory

hmm,
I checked the tarball on a 32bit fedora16 vm
(After creating a snapshot of course.
The site looks legit,but better safe than sorry )

On this system, the error is different:

./stanv3s.linux 
bash: ./stanv3s.linux: /lib/ld-linux.so.1: bad ELF interpreter: No such file or directory

stanv3.linux and stanv3s are *both* dynamically linked.
Probably the "s" shall indicate a static binary, but it is not.

They both need the same libs and versions:

[tester@fedora16 STAN.V3]$ ldd stanv3*.linux
stanv3.linux:
	linux-gate.so.1 =>  (0x00662000)
	libg++.so.27 => not found
	libstdc++.so.27 => not found
	libm.so.5 => not found
	libc.so.5 => not found
stanv3s.linux:
	linux-gate.so.1 =>  (0x00f49000)
	libg++.so.27 => not found
	libstdc++.so.27 => not found
	libm.so.5 => not found
	libc.so.5 => not found

So my guess is, that you need to ask for
- the sources and compile yourself
- or another binary, more suitable for modern OSs

I see... Actually i found some source code, tried to compile, but could not, even with some changes in the makefile and sources. I seems like a lib problem as well. Thanks for you help, i really enjoyed the ldd command
