[[e-mail] [hercules-390]]

I have been running Hercules on Linux OPENSUSE Leap 42.2
The Hercules version that is pre-installed is 3.11
How can I upgrade Hercules to version 3.12 ?

If you're willing to build from source, then
you can go here:

http://www.hercules-390.eu/

and download the source code.

Yes, I think I can try to do that and rebuild from source. Thanks.

I finally got around to rebuilding Hercules 3.12 from source on Linux. After the upgrade was done, when I run Hercules and try to IPL z/os 1.10 the following error is issued:


14:07:03 IPL 0A80
14:07:03 HHCCD124E 0A80 file[0] invalid trk hdr trk 0: zlib compression unsupported
I had no problem running z/os with Hercules 3.11
any thoughts what went wrong ?

Kalda0912,

the problem is that when you prepared the compile-job there was no
package installed that supported compression - I am not a linux-guru so
you have to find one yourself-

once you have that you can rerun the three steps to prepare from source
and it will support your compressed disk-images.

Thanks for the quick response. So once I find a compression package, I need to redo steps 4-5-6 ?

Which Linux distribution are you running? Some Linux distributions, like
Debian, have separate library and "development header" packages. On Debian,
for example, you only need the zlib1g package for zlib support when running
a pre-built Hercules, but also need zlib1g-dev to build Hercules with zlib
support.

As mentioned in the OP, I'm running Linux OPENSUSE Leap 42.2

Then you would need the zlib-dev package to build Hercules from source with
zlib support.

I installed the required package and rebuilt Hercules from source.
This has resolved the problem.
Thank you all.

Did you also do bzlib and pcre ?

I don't build Hercules but have heard them mentioned by others.

bzlib is only required if you use BZ2 compressed CCKD/HET

PCRE and brexx or Regina Rexx are only needed for HAO (Hercules
Automated Operator) functions.

At one time CCKD would switch from zlib to bzlib if zlib had trouble
keeping up with compression to write to disk.

I assUme that no cckd disk images with bzlib tracks can ever be used?

HAO can be handy.
If PCRE and Rexx are needed, why purposefully build without?

Because it's just too complex to figure out whatever the darn package names
are called for the particular Linux distribution you happen to be using at
the time.

Even without currently using Debian or OpenSuSE I had no trouble figuring
out their zlib development package names using their online package
searches.

Sorry, I was only kidding.

(But have you ever looked for the Arch Linux 'development packages' ? There
aren't any. They package all the 'development stuff' right in the base
package.)

Sorry again.

No apology necessary. I suspected you might be. But I wanted to let others
that might be following the thread and considering building Hercules on
Linux that finding the dependencies it needs isn't hard.

I know. Arch Linux was my desktop OS for quite a while. Though I switched
to Gentoo to get away from systemd. I do still have Arch running on a
couple of Raspberry Pi's.

I don't build Hercules or run Linux but suspect that your build
instructions mention some bzlib-development package and
perhaps other packages.

That's about as helpful as saying :

"I don't build Hercules or run Windows but suspect that your build
instructions mention some 'Visual C' thingy, an SDK-development thingy and
perhaps other thingy's. "

Yes, if the knowledgeable people aren't giving up the information
at this time, suggesting that the user read the documentation
might be helpful?

We already have zlib-dev, bzlib-dev, PCRE, and a choice between
a couple of flavors of Rexx mentioned.

Is more information needed?

I'm sorry, but I stopped reading your helpful 'Hercules build instructions
for Linux' right after reading the start of your sentence which reads :

"I don't build Hercules"

and

"or run Linux"

No apology needed.
I understand completely and appreciate your comment.

I did notice something unusual..

Of the four set of instruction for building Hercules under
Windows that I located, only Hercules 4.00 Installation
Guide mentioned Rexx. I assUme that Rexx is only
needed for the upgraded HAO support in Hyperion?

Neither Hercules Installation Guide mentioned zlib, libbz,
pcre, or rexx for Linux but zlib and bzlib are needed for
full CCKD support and some HAO needs pcre and rexx.
.het also needs zlib-dev

http://hercdoc.glanzmann.org/

The unofficial version of Hyperion uses the hyperion
manuals so is the same as the official hyperion:
