I'll use Github for now on if I encounter anymore new issues. Thanks!
As for the link you provided, I'll give a try when I have time to see if it works on my end.
I cannot test, but presumably fixed in https://github.com/macos-powerpc/powerpc-ports/commit/8377b7cf28672b05bc5cced6ba69a68d474a117a
I just managed to test it today and was able to successfully install QMPlay2 on my Powerbook G4 with your changes. Thank you!
The only thing that I'm running into now is that the video doesn't show up when I try to play it from a Youtube search result but at least I can hear the audio though. Also, the same issue happens when I try to download a video from the Youtube search results to try to play it back. What I have done so far is change the video quality to 480p and left the codec as VP9 but even that did not work during playback.
I cannot remember if there was a way to fix it and I maybe wrong but I think someone else brought this up but I cannot recall.
What happens if you download and play the same video locally? If that works, there is no issue with ffmpeg and GL, and likely the problem is with too-weak hardware. (On my G5s everything works, AFAICT.)
You may try setting default format to something less CPU-intensive. Turning off video to audio sync in playback settings also helps to make it easier.
When I download and play the video locally, it works but it depends on the video itself. Because I used VLC to test it out, sometimes it'll play fine while other times it will fail to load it since it does not know the codec (usually the logs will mention 'undef' during playback).
For now, I will use your suggestions to see if it will improve the playback.
What I am interested to know if the same video which fails to stream plays normally in QMPlay2 on the same machine. Comparing to VLC is a different question. If QMPlay does not play local videos (reasonable ones given hardware; it won’t play 4k AV1 on a G4, and no player will), we got a bug to address. If hardware is just too slow to handle streaming and decoding of certain formats, there is nothing to fix about it, it is an expected behavior.
I'm building my fork of dingusppc in Mac OS X 10.5.8 ppc 32-bit. I'm using gcc14 since gcc15 doesn't build.
How do I debug my executable?
I created an Xcode project using "external build system" in the build folder that contains the makefile created by cmake since cmake can't create an Xcode project for Xcode 3.1.4.
I've added all the source files. Xcode will use make to make the executable and it will startup the debugger.
The Xcode debugger doesn't seem to like the debug symbols even though
I am looking for a bug that appears to be in CLI11 in this line of main in my fork of dingusppc:
I think all the code for CLI11 is in a single .hpp file? No external library.
I'm using the version of gdb that came with Xcode 3.1.4.

(gdb)I would rather use the Xcode app to do debugging so I don't need to remember gdb commands but it doesn't work with the old or new GDB.
The new GDB won't start the app - or it crashes immeditiately?
The old GDB doesn't seem to be able to debug main. I can set a break point on
malloc_error_break but the backtrace command doesn't show main.Those malloc errors are result of C++ runtime conflicts. Often they are more or less harmless but sometimes cause nasty breakages.
You can likely fix that by using a wrapper script that sets DYLD_LIBRARY_PATH to the right libgcc. See what legacy-support port group does for redirect_bins option.
You can also check opencv4-devel and musikcube ports, where I do the same manually.
This problem is solved by having Xcode use
sudo gdb-apple.The following commands will set that up:
Code:
[[ -f /opt/local/bin/gdb-apple-sudo ]] && sudo rm /opt/local/bin/gdb-apple-sudo
{
cat <<- 'DONE'
#!/bin/bash
sudo /opt/local/bin/gdb-apple "$@"
DONE
} > /tmp/gdb-apple-sudo
sudo mv /tmp/gdb-apple-sudo /opt/local/bin/gdb-apple-sudo
sudo chmod 777 /opt/local/bin/gdb-apple-sudo
defaults write com.apple.Xcode PBXGDBPath /opt/local/bin/gdb-apple-sudoI still need to solve this problem. Does this problem mean the executable cannot run on a different machine that doesn't have the same libgcc?
Ah, yeah, gdb needs to run with sudo. I just did not recognize your error.
macOS has its libstdc++ in /usr/lib, while modern gcc has its own, in /opt/local/lib/libgcc (in case of MacPorts). That can create problems at runtime, when symbols are picked from a wrong libstdc++. Usually this problem is fixed by setting DYLIB_LIBRARY_PATH to where the modern libstdc++ resides. It is not the best solution, but a poor man’s one – but it works.
@Matias_ @Forest Expertise I made some changes which hopefully improve bootstrapping of curl. `brotli-bootstrap` builds with Xcode gcc, and curl now accepts it to satisfy the dependency. I have also provisionally fixed universal builds (don’t expect +universal to work reliably though LOL).
curl-bootstrap updated to 8.19.0 (with openssl 3.6.1, etc.)
PPCPorts to 2.12.3.
(These are for 10.6 ppc / i386 / x86_64. Won’t install on earlier systems.)

Thanks a lot, can a sync the ports easily or do I have it to fix manually? If manually then I need your advice again how to do it.
UPD.: fixed it with Sync. Thanks.

One the matter: if you just want to pick a new portfile with patches as-they-are, you can use `sip` for port directory, then copy it into a local overlay and run `portindex` over it. If it is something trivial like few lines replaced, copy-paste works )
The
sudo in that script only works if sudo was performed recently in Terminal.app since Xcode's debugger doesn't show a prompt for sudo.What is the best solution?
The name of the variable is DYLD_LIBRARY_PATH (which you had correct in a previous post). Setting it does remove the "Non-aligned pointer being freed" error messages but doesn't fix the CLI11 error message "Requires at most 1 options be given from".
I added

Another LCS failure to save:
Picked up this Dual 2.7 that boots but doesn't get past the Apple logo. LCS o-rings failed, didn't spread very far so this should be salvageable. I pulled the rebuilt LCS out of my Dual 2.5 and it booted right up - passes every test in ASD and works like a charm. Will use it with the current "Frankenstein" configuration until I can get the 2.7 CPUs cleaned and the LCS rebuilt.
Glad to have an extra machine for sending long builds to. This has also helped me confirm that my Dual 2.5 no-boot condition is the logic board, not CPUs (since they work in the 2.7), and that my first LCS rebuild works as intended. These are excellent thermals!

Yes, in principle. No idea if something works out-of-the-box or in desired way.
1. pulseaudio is cursed, but presumably can work. I tried to get it working once, on Sonoma, failed and gave up LOL
Perhaps the issue was that I did not use it at all before – someone with Linux background may have no difficulties.
2. Jack 2.x is broken with gcc, but Jack 1.x builds fine. Presumably it can work on macOS. May need API adjustments in cubeb.
3. AudioUnit should be fixable, it has only few cases of blocks and some dispatch stuff: https://github.com/mozilla/cubeb/blob/master/src/cubeb_audiounit.cpp
But it won't compile without some fix-ups.
P. S. I can add a fix to enable AudioUnit, perhaps, but you will need to test it. I do not know how and where to use cubeb.
Upd. Fixed for 10.6 ppc.

I can do a test with DingusPPC. It's needed for the boot chime. Without an audio unit, the emulated Mac never sees the audio end.
