Applications / New DOSBOX build / new ports
« on: June 12, 2017, 11:30:37 am »
After getting ArcaOS set up and got the development envorinment set up, I can now proudly announce a new build of DOSBOX with the latest source code changes. You can fetch it at
I will also submit the installer to Hobbes.
Since I build against the RPM repos, you will only need the packaged DLLs, if you are not using RPM.

PS: I couldn't add the news to the Netlabs WIKI DOSBOX page, since I can't login at the moment. If someboy would be so kind, to add the announcement, I would be grateful.
EDIT: This build contains SDL_SOUND support again.

Programming / Problems with configure
« on: January 28, 2016, 08:38:09 am »
Hi there.

I have a problems with this configure from SDL, I'm working on.
I get the message
Code: [Select]
./configure.lineno: 23670: Syntax error: "fi" unexpected (expecting "then")I don't know why. If I remove the offending code, then the error moves to another part of the script.
So I think the error is somewhere. As I'm no expert in shell programming, I don't know where to look at.
Autoconf is 2.69, automake is 1.14.1-3.

Programming / Multimedia with GCC
« on: January 11, 2016, 10:17:36 am »

I'm building SDL with GCC.
My problem is the typedef PACB (pointer to struct ACB).
I can find no definition in the OS/2 toolkit 4.5, although some multimedia API needs it.
The only definition, I could find, was in a Watcom C header.
My question: Am I overlooking something? Is there some packages (rpm or something else) I need to install?
Or have I to set up a C header file for the definition.

Programming / libc panic

I'm porting nginx. I was able to build a binary and nginx can serve me static HTML pages.
I can stop nginx via process signaling. That just works fine.
But if I want to restart nginx, I get the following:
Code: [Select]
nginx: [alert] shmget(384) failed (22: Invalid argument)

safesem mutex requested failed, rc=0x6. pmtx=5fe10960:{.hmtx=0x800100fb .fShared
pid=0x0fbb ppid=0x0b43 tid=0x0001 slot=0x009c pri=0x0200 mc=0x0001 ps=0x0017
Process dumping was disabled, use DUMPPROC / PROCDUMP to enable it.

Now, I have to reboot to get nginx running again.

I have the newest klibc installed and the binary is compiled with gcc 4.9.2.
Does anyone have suggestions, how to handle the problem?

Bye Jochen

PS: If someone wants to test the port, PM me.  I'll send you the binary.
