Shell Programming and Scripting

Hi.
+1

The config.guess shell script referred to by yazu is very thorough and can discriminate among an impressive number of systems.

Even if you do not use config.guess directly, you may be able to learn something from how they determine the system, including the use of uname ... cheers, drl

Hi Purdym,

Yes,I am using the same approach, however I just want to understand what should be used on every specific platform in order to identify the software compatibility.

When we say a software is compatible for 32-bit/x86/i386 etc. what it refers to

is it processor type or hardware platform or hardware name (e.g. Linux Uname flags -p,-i or -m respectively) or its something else.
If you can clarify this I will be able to look for appropriate flags to be listed.

Thanks

At a macro level, it depends on:

- Endianness, i.e. Big or Little
- Data model, i.e. LP16, ILP32, LP64, etc.
- Hardware architecture, i.e. x86, MIPS, SPARC, etc.

Hi.

The config.guess produces the signature on an AIX box as:

Code:

$ config.guess 
powerpc-ibm-aix5.1.0.0

on an HP box as:

Code:

$ config.guess 
hppa1.1-hp-hpux11.11

on a GNU/Debian Linux amd64 machine as:

Code:

% config.guess 
x86_64-unknown-linux-gnu

These are copies of the script without modification as run on those machines, simply ftp'd and run.

Best wishes ... cheers, drl
