shc doesn't work

chuanpeng.wang — Tue, 19 Aug 2008 04:50:57 GMT

I try compile a script to binary file with shc.
But shc doesn't work on my server.
I have installed HP C/aC++ Compiler on the server.
Is there other compiler needed?
The version of shc is 3.8.6.

Hi,
There is permission denied.
Please provide the the process to execute, it will better if you can give chmod 777. Then you try further.

>Gokul: There is permission denied. it will better if you can give chmod 777.

There is no permission problem. It already is executable: -rwxr-xr-x shc
You should never use 777, at most use "chmod a+x".

Try "file shc". This is probably an executable for IPF (if on PA) or some foreign devil machine.

>> /usr/bin/sh: ./shc: Execute permission denied

provide following:

which shc

ll path to shc

after install shc should have 755...

I try make test on both PA and IA servers.
The error is identical.

This should work fine but only on IPF.
Since shc is small, could you attach it to your reply?

>This should work fine but only on IPF.

Oops, didn't look close enough. This is from some foreign devil machine, most likely x86 linux. HP-UX IPF has:
/usr/bin/ksh: ELF-32 executable object file - IA64

elfdump doesn't like it either:
$ elfdump -f shc
*** ELF Header ***

Data: Little-endian
OS: 0
ABI Version: 0

elfdump: Bad machine: 3 (elfdumperr 3004)

You need to remove shc, then make it.

These are gcc options. Just replace all those by -O. If you are on IPF, you can replace -Wall by +wlint.

Hi,

it's maybe not an issue, but:
you have for example:
-rw-r----- 1 501 501 17982 May 10 1996 Copying

The owner and the group seems to be unknown!
I would change ownership to your test-user/group.
At the moment some files are not readable by users not in this group '501' - and normally a number means this user-/group-id is unknown by the system.

shc works with -r -T -f.
