Multimedia / Re: Can aswitch.exe be used for always connected/attached usb speakers?

« on: October 14, 2024, 08:10:32 am »

Too bad. I only fixed SDL2. I cannot even find the SDL that we use.
Maybe it's time to build a version of dosbox that uses SDL2.

Hmm, looking, DosBoxes last release was 5 years back, so likely no SDL2 support though I didn't find build instructions.
There are forks such as DosBox-X, https://dosbox-x.com/ which would be nice to have. Even it comes with an intree heavily modified SDL as well as support for SDL2. This one would be nice to have as it is expanded to run most DOS apps including Win9x.
There is also SDL3 now

SDL3 would be a good add-on to our video libraries. What is really sad is the lack of OpenGL support - though I guess it is almost useless without a real accelerated video driver. But alas, an OpenGL comeback on OS/2 would allow porting many applications. I know - we are a little community.

But let me dream

Programming / Re: Classic, Regina, Object and Open Object Rexx

« on: October 03, 2024, 08:17:29 am »

Is Open Object Rexx (by RexxLA) what was/called NetRexx? I vaguely remember some presentation on some Warpstock Europe some time ago...

AFAIK, Andi, NetRexx was/is (?) something related to Java: quoting the NetRexx website
"NetRexx is a general-purpose programming language inspired by two very different programming languages, Rexx and Java."

Though I feel Netrexx and ooRexx have many things in common, ISTR there is also a converter from / to Netrexx under OS/2.

I don't think there are any choices on OS/2 other than apache2

Did anyone take a look at nginx?
(I should go look at it, BTW - it's really good for things like reverse proxy).

Fairly complete description, Jan-Erik. Thanks.
Some of these details I didn't know very well - as far as I can remember, Object REXX was heavily criticized on Warp 4 and almost never used - I stayed on Classic REXX, like many of us.
I also used DrDialog and GPF Rexx (too bad they're discontinued) to build some fancy apps for my theatre activities and boy, was it fun.

I'm currently too involved in porting OS/2 apps from the open source entourage so I don't have time, but in the future I'm willing to write some other useful GUI application in REXX, mostly for my activities as a musician and electronic engineer.

The interesting part of REXX on OS/2 is its integration with the system and SOM - I see many similarities between {OS/2, SOM, REXX} and the .NET environment on Windows and Linux with its Powershell scripting language, though I prefer the more elegant REXX syntax (Powershell can really be a drag). So yes, being able to integrate Regina or ooRexx with OS/2 (and SOM) would give us a big step forward.

Programming / Re: [GCC] Unable to define getMemorySize()

« on: October 01, 2024, 08:14:11 am »

Last update: yes, getrusage is available in our libc. Compiling it - will test this binary asap and - if it works as I expect - it's going to HobbesArchive.
Mentore

Seems like our getrusage does not return any memory size information, only use of time ("ru_utime", "ru_stime").
I suspect this is not what you are looking for.
As to memory: Rich Walsh has elaborated somewhere in this forum about what the various memory sizes mean and how they play together:

https://www.os2world.com/forum/index.php/topic,3445.msg41758.html#msg41758

It would be nice if we could get that added to "getrusage".

This is pretty interesting. I did a little testing of the executable and found it works (at least to some extent), but - since it still doesn't launch any graphical interface like gnuplot - I'll surely have to get back to it.
What's sure is that I need to know what actually getrusage does (or, for what's worth, GetProcessInfo from the Win32 counterpart) - the other methods in that function involve using the /proc interface which OS/2 allegedly doesn't implement.

You guys are invaluable 

It's compiling... Will let you know.
Mentore

Compiled. Had to circumvent other two problems though:

• In get_resident_set_size.c there are some calls to get the memory used by the process. I don't know if we have getrusage available, so I  remembered processes on OS/2 were limited to 512MB and decided to return a fixed size of 400MB. I'm almost sure it's a stupid idea but will try it. I have to search for getrusage in libc.
• BOOL is defined as unsigned int, conflicting with os2.h definition. Corrected.
• There was another reference to getMemorySize() in another .c file, also tackled this.

Now ngspice-42.exe is available under OS/2 as beta - will try and see if I can use rusage instead of reporting a fixed 400MB memory used by the process.

Looks like you will have to write an OS/2 get_avail_mem_size.

Oh, that may be actual fun guess I'll give it a go asap.

Programming / [GCC] Unable to define getMemorySize()

« on: September 25, 2024, 02:25:59 pm »

Hiya all,

Trying to port NGSpice 4.2 (3.1 compiled just fine). Everything right until this:

get_avail_mem_size.c:26:2: error: #error "Unable to define getMemorySize( ) for an unknown OS."

Where can I find the definition of getMemorySize() under OS/2? Or should I try and clear this OS definition in configuring the environment?
TIA

Events / Re: Warpstock 2024: Coming? Not Coming? Why?

« on: September 11, 2024, 08:14:14 am »

Rather than try to discuss this in the Warpstock forums, which are lightly trafficked, I thought I'd ask this here.

Some may not be familiar with Pittsburgh, or have misconceptions about its charm. I suggest a quick trip to Wikipedia for a refresher. Pittsburgh is rich with history and culture, and there is an excellent technology museum there (we're working on a potential evening outing there during the event - no promises, but we can always do something impromptu).

Another thing is the hotel group rate.

<-- snip -->


So, if you are coming to Warpstock this year, please mention why. If not, please go into some detail as to your reasons for not making the trip (travel cost, hassle of getting there, registration cost, bad timing, lack of enthusiasm for the location, etc.). We want to know.

Thanks!

As much as I'd love to meet other OS/2 enthusiasts like me, I'm afraid Warpstock and Warpstock Europe are all off limits for me.
The only thing I don't lack is enthusiasm, both for the platform and the events. I don't have time nor resources to afford the trip, and having a wife, a two-and-a-half years old son, a full time job and other jobs, there's really too much to do here for me to leave for a few days.
I'll try to follow the recordings as soon as I have the time to do so. Yes it's a second choice, but alas, there's nothing else available.

A quick note on involving youngsters: I totally agree in saying there should be something to do with students. I feel OS/2 has really much to say in STEM fields, where its stability can rival with other platforms and a more coherent user interface may guarantee a better user experience than its most relevant competitor (which is surely Linux: Windows is too far). This should be the most important point to stress out, since Linux is unbeatable when it comes to money (but still, not free - you have a steep learning curve even with the most "windows-ish" distributions).

Hope everyone attending this year's Warpstock will have a great time.

General Discussion / Re: Introduction post....

« on: August 14, 2024, 11:17:03 pm »

First time posting on this forum though I've been an OS/2 user since 1995. Today I rely on different Linux distros to do most work as platform of choice. I have a rugged laptop that I use for my copy of ArcaOS which I have setup to operate and look as OS/2 Warp once did.

I've been in the email chain and on the Facebook OS/2 groups for a while. In a subsequent post I will put a link out in these forums about establishing an OS/2 Warp Appreciation Day set for October 11th 2024, 30 years since the IBM release of OS/2 Warp 3.0. Folks will get to know me better as my participation here grows with you all.

Thank You and My Regards,

Jason Page

Programming / Re: GCC - updates

« on: July 11, 2024, 11:15:03 am »

Hey Mentore,

I've deliberately set this up to easily work *with* rpm gcc 9.2.0.

Unzip it to the root of the same drive you have rpm installed on. To switch to a newer gcc, 'set path=c:\usr\local1330\bin;%path%' (or whatever the path is).  GCC 9.2.0 will still be installed into c:\usr\bin and it's easy to change between them.

Cheers,

Paul.

Fantastic job Paul, as usual.
Thanks!

More testing to be done, but https://smedley.id.au/tmp/gcc-13.3.0-os2-20240710.zip seems to correctly create debug symbols...

GCC 14.1.0  is giving some errors builing libgcc with debug code:

Code: [Select]

during RTL pass: final
../.././libgcc/libgcc2.c: In function '__muldi3':
../.././libgcc/libgcc2.c:538:1: internal compiler error: in eliminate_regs, at reload1.cc:2938
  538 | }


As usual, fantastic job Paul.
May I ask if it is possible to directly substitute this over, say, GCC 9.2.0 from the netlabs YUM/RPM repository?
