Games / Alien Blaster
« on: December 28, 2021, 01:05:53 am »
Martin asked me on IRC about an update to Alien Blaster, so I built it.

Not really tested  - but

This zip includes all sources as well as I was too lazy to figure out what files are needed to let it run.

Needs sdl12 libs.

Programming / Updated GCC Builds
« on: May 02, 2021, 10:43:13 am »
Hi All,

I got a announcement email for GCC 11.1.0 last week, which reminded me I hadn't produced any GCC builds for some time..

Anyhow, with not too many brain cells burned out, I ended up with:

Both have been tested only as far as being able to build themselves.

No gccenv.cmd or anything included, it's expected if you want to play with these, you know what you're doing :)



Hardware / WebCam and Libusb
« on: January 20, 2021, 04:58:37 am »
Hi Wim,

When I started developing webcam support I produced USB Webcam Tests that required usbecd.sys in order to function. It only supported a few webcams owned by those persons that helped me out by testing. It is not recommended to be used anymore. At that time only usbecd.sys supported the required isochronous transfers. Since then I worked on usbcalls.dll and usbresmg.sys to implement a.o. isochronous transfers and that capability is nowadays present in both ArcaOS and Lars Erdmann drivers.

What would be really cool would be to add support to our libusb port for ISO transfers - that would simplify porting linux apps that support webcams using (iirc) libuvc....



Applications / gImageReader - qt5 OCR application
« on: September 18, 2020, 04:55:35 am »
Hi all,

Per some discussion on the eComStation yahoo group mailing list, I've built gImageReader - a Qt5 application that uses the tesseract OCR engine.

This seems to work - albeit the GUI is a little painful to use - at least in my VM.

I've tried to document the dependencies below - no promises I didn't miss anything :)

gImageReader-qt5.exe + qtspell0.dll + quazip51.dll -

libcx0.dll -
poppq51.dll - (yum install poppler-qt5)
qt5 DLL's - (yum install qt5)
usb100.dll - (yum install libusb1)

A copy of the relevant language file for tesseract (the OCR Engine) - see for downloads.

Tesseract language files can go in /tesseract/share/tessdata - or edit preferences in gImageReader to specify a local directory.



Games / OpenTTD 1.10.3 for OS/2
« on: September 03, 2020, 07:08:34 am »
Hi All,

This is the current release of Open Transport Tycoon for OS/2

Note this is binaries only - it's necessary to install a set of graphics/sounds/etc from

I've only tested enough to see the main page opens.

Also needs sdl 1.2 libraries.



Programming / Updated Perl
« on: August 30, 2020, 05:02:13 am »
Hi All,

I discovered that openssl 1.1.1 uses Perl to configure/build - and with Steven's help, had to make some fixes to Perl/2

After getting openssl 1.1.1 building, I figured I should try and update Perl - the result is

Feedback appreciated - only tested enough to build openssl 1.1.1



Applications / Subversion 1.14.0
« on: July 18, 2020, 11:23:54 am »
Hi guys,

I finally got a newer SVN client that 1.7.21 working on OS/2

Tested is the ability to retrieve repositories from http and https repositories and to commit simple changes.

That's about the extent of my current testing :)

For anyone feeling brave -

Feedback appreciated



Hardware / Odroid H2+
« on: July 15, 2020, 01:04:21 am »
Hi All,

Any thoughts on the likelihood of getting ArcaOS to boot on an Odroid H2+?

Issues I see:
- No CSM support (conformed on forums), so would need access to a UEFI build of ArcaOS
- possibly no NIC support - not sure if the RTL8125B is supported by the ArcaOS drivers - given the references to adding missing linux drivers, I suspect this is a newer chipset.

However - it does have SATA ports in addition to NVMe.

Not quite as small as a RasPi at 110mm x 110mm x 47mm but still would be pretty cool if it worked.

I'm tempted to order one and see how I go, given that I can always redeploy for other purposes within my home LAN if needs be.



Programming / Python 3.x?
« on: June 27, 2020, 11:55:26 am »
Hi All,

Wondering how much interest there might be in a Python 3.x port? OS/2 support was removed from the source code around Python 3.3 - so it will be a reasonable amount of work to re-instate it. However, Samba keeps marching towards Python 3.x, and I fear that soon our 2.7.x build won't be good enough to keep Samba current....



Networking / Samba Server v4.11.9
« on: June 21, 2020, 10:34:56 am »
Hi All,

I'm now at a point in Samba Server development where i'm prepared to publicly share some binaries based on Samba v4.11.9

Client tools/DLLs:

Server executables:

Note: no installer is available yet, and I have no real idea what's involved in upgrading a Server running v3.6.x to v4.11.9

Note: by default Samba v4.11 only accepts SMB2+ connections - you can enable SMB1, but you need to be aware of the security implications.

This has now had a reasonable amount of testing from linux, Windows and OS/2 (using the Samba 4.x client).

I'm not aware of any significant bugs - known issues are the log file being created as log.smbd.exe not log.smbd - but this is a low priority to fix right now.

Feedback appreciated.



Networking / Samba Server v4.11.7
« on: May 20, 2020, 11:24:13 pm »
Hi All,

Looking for a small number of testers who are willing to test and provide feedback on Samba Server v4.11.7.

This is pretty hot off the presses, and has not yet truly been stress tested. Having said that, the patches are based on the changes that were made for Samba 3.x; and also the changes I made to get the Samba Client based on v4.x working some years ago.

I'd been working on the server on/off for a while, but had hit issues, for which I had a lightbulb moment this week and resolved.

The only real pre-requisites are:
- you need to understand that this is not very well tested yet - and there is a remote chance of it causing data loss.
- you need to understand that support on configuration is not going to be provided - I just don't have the spare time to provide this - and google will do a much better job that me anyway
- you need to be willing to share feedback

For now, I'm not willing to post a link to binaries online due to the lack of testing mentioned above, so contact me via email (paul at smedley dot id dot au) if you're interested in helping.

For Samba 4.11 and above, SMB1 is OFF by default - it can be enabled in smb.conf



Multimedia / Updated Uniaud32 build
« on: May 06, 2020, 11:00:30 am »
Hi All,

Prompted by Lewis reporting a problem with no sound on a newish laptop, I built uniaud32.sys last night for the first time since December 2015.

After managing to patch the realtek driver to add some additional chipsets which got Lewis sound, I got interested again in updating Uniaud.

As some may recall, way back when, I was updating the uniaud32 core with the latest ALSA code.... I got as far as ALSA 1.0.24 (released January 2011), but could never get ALSA 1.0.25 (released early 2012) to work. After that, the code was incorporated into the linux kernel, and it all got too hard. Plus, at the time, we still had the hangs with hda audio and I started running linux as my main OS.

Anyhow, after helping Lewis last night, I added the OS/2 patches to the linux kernel 3.0 code and got it building. This represents an alsa-kernel approximately 6 months newer that what's in the last uniaud32 release.

I've tested this in virtualbox with the Intel HDA driver and it still makes sound. That's about the level of testing I've done. I can't be bothered walking upstairs to grab one of the Thinkpads and test on other hardware.

Anyway...... link is

Feedback appreciated. If there's interest, I'll continue to try and update the code to hopefully fix upstream bugs and support newer hardware.



Networking / uacme
« on: October 26, 2019, 10:15:16 am »
Hi All,

Massimo asked me about porting a client for Let's Encrypt - uacme seemed like it didn't have too many dependencies, so I built it.

needs latest libc and libcx, as well as GNUTLS libs from hobbes.

Feedback appreciated.


Applications / MySQL 5.6.46
« on: October 26, 2019, 10:13:22 am »
Hi All,

based on my patches to MySQL 5.5, I updated the source to 5.6.46 and OS/2 binaries are available from

This is very lightly tested, but so far at least, appears to work OK.

Not sure how many people are still running MySQL on OS/2?



Networking / Samba 4.9.0 based client
« on: September 15, 2018, 10:22:45 am »
Hi All,

Updated Samba client build for testing - seems OK here - both smbclient.exe and ndpsmb.dll have been tested.

Netdrive plugin (depends on smbcln49.dll for samba libraries support) -

Samba client libraries and associated utilities:

As per previous builds, these also need an ldap.dll from openldap ( and the heimdall DLL's (

Feedback appreciated!
