Python Installation - Execute Permissions

[GBR]

I've just installed 2.4.3 on my HP-UX 11i v1 box. I'm getting an execute permission denied error when I try running the command 'python'. The executable is in my path. Any ideas?

Thanks,
Greg

Shalom,

ll /filename

what /filename

Make sure you have PA-RISC executables. IA64 will not work on 11.11

# ll /usr/bin/python

lrwxr-xr-x 1 root sys
1 Jul 19 17:59 /usr/bin/python -> /usr/local/bin/python

# what user/bin/python

/usr/bin/python:
$Revision: 92453-07 linker linker crt0.o B.11.43 050125 $

And... I'm not sure how to check that I have PA-RISC executables.

Command "file /usr/bin/python" should say something along the lines of "PA-RISC 2.0 executable...."

If it says something about ELF, you've got the wrong python.

# file /usr/bin/python

/usr/bin/python: PA-RISC2.0 shared executable dynamically linked -not stripped

what machine is this? it may be a PARISC 1.x server, in which case you will get this due to using an executable compiled on a PARISC 2.0 server

Melvyn,

CPU Version: PA 7200-7200 CPU 13
Hardware Model: 9000/821/D250
Kernel Width Support: 32

So should I be looking for a PARISC 1.x compilation?

By running the follwing command:

# file /stand/vmunix

/stand/vmunix: PA-RISC1.1 executable -not stripped

I will now go looking for a compiled executable for a PA-RISC1.1

Yes, you have a PARISC 1.x server, you need the version compiled for that.
As you have the PARISC 2.0 compiled version, you will get the error you are seeing

Can any PA-RISC 2 compiled code run on PA-RISC 1.1? or do I have to compile all the code on my system for the PA-RISC 1.1 architecture to work properly. I ask because I installed Perl with for PA-RISC 2.0 and it seems to work.

[melvyn burnard]

well the simple answer is it depends.
I say that as I have seen this origionally where Oracle binaries are compiled on a PARISC 2.0 serevr, then copied to a PARISC 1.x server.
Some of the exectuables wporked, others failed with exactly the same symptoms you see. I am not exactly a compiler or language expert, so I do not have a definitive answer as to why.

[GBR]

But if you were rebuilding this old box, would you be recommending compiling the source for each app, so I don't end up with issue downs the road? From what I can see it hard to find compiled binaries for PA-RISC 2.0, so I pretty much have no option.

I'm new to the Unix world of installing apps, and I'm assuming that if perform the compilation right on the box, to do the install, that it will work way better than trying to install the PA-RISC 2.0 depots.

No. Yes, you should compile with +DAportable.

> I ask because I installed Perl with for PA-RISC 2.0 and it seems to work.

I don't see how. Unless it just says for PA2.0 and not "Only for PA 2.0".

Thanks to all.
