HP-UX

i had read somewhere and also in cygmin (under "what isn't")..that native compiled executeables in linux can't be run under cygwin...they need to be recompiled under cygwin to operate..it is true?

so if i have natively compiled program (in unix), can i still literally port to cygwin and run it? thanks

i think i have found my ans, no binary executeable compiled in unix environment can be ported and run in cygwin..

That is correct. UNIX and UNIX-like OSs such as Linux do not guarantee binary portability. You are expected to recompile the application source code for each target platform and programming model.

In the OS world the term "porting" has a specific meaning. It does not just mean just transfer an application binary from one platform to another - say Unix to Cygwin. It means to take the application source code, modify it as necessary and recompile it for the target platform.

you are right, can i check what other tools should i explore if i wish not to perform recompilation of my unix apps but still wish to run in windows os machine with a unix emulator?

Reason being, my existing unix apps have too many imports which i don't think i would wish to spend time recompiling each of them in the cygwin. i just wish to take them and run in a windows machine..

I'm pretty sure your HP UX applications will NOT run on any other platform, be it Linux, Cygwin, or other unices, without porting, which implies adaption and recompilation of every single module.

Not possible for HP-UX binaries.

HI.

My understandings: if the user has a recent HP box, then it has an Itanium CPU, whereas older HP boxes use PARISC. Neither of the binaries that run on those can be run directly on an Intel box. Cygwin runs on MS/Windows, Windows only runs on Intel CPUs (no more Alpha, no more MIPS).

I think there are some solutions for "just moving the binaries over", but on a non-HP box, say an Intel Linux machine, first one would need to emulate PARISC or Itanium instructions. Then install HP-UX, then move the applications over. Or do the same on an MS/Windows box -- get a PARISC or Itanium emulator running on Windows, install HP-UX, etc., etc.

I think it would be much easier to re-compile the code. I don't know what "existing unix apps have too many imports" means.

The Cygwin that I use definitely has the tools to re-compile code:

Code:

$ version =o gcc g++ g77 make
OS, ker|rel, machine: CYGWIN_NT-6.1, 1.7.17(0.262/5/3), i686
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
g++ (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
g77 GNU Fortran (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
make GNU Make 3.82.90

For example:

Code:

$ make t
cc     t.c   -o t
$ ./t
Hello, world from c.

To show what happens when an HP-UX binary attempts to run on an Intel Linux box, I copied /sbin/ls from an HP box to a Linux workstation. Then I did an ls on both files (and validating the Linux binary -- it produced output):

Code:

% /bin/ls -gGl /bin/ls hpux-ls 
-rwxr-xr-x 1 101992 Apr  4  2008 /bin/ls
-rwxr-xr-x 1 286720 Mar 24 14:47 hpux-ls

then I identified both applications:

Code:

% file /bin/ls hpux-ls 
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped
hpux-ls: PA-RISC1.1 shared executable

and then I tried to run the HP application:

Code:

% ./hpux-ls 
./hpux-ls: Exec format error. Binary file not executable.

so we have permission to run it, but the format is not understandable.

others have already commented on the OS aspects.

Good luck and best wishes ... cheers, drl

( edit 1: corrected spelling )

i realized that there is this "Wine" which can help to run Unix Apps. anyone had tried and can advised which package to down for HP UNIX? thanks
