SteamOS about xow

[andreashuetter]

I have good news!
After downloading the latest version of libusb from https://github.com/libusb/libusb/releases and compiling it manually I was able to get xow to run on SteamOS and it also works with BOTH of my dongles (the older bulky one, and the new smaller one).

Strange thing, though, is that after rebooting the machine it does not work anymore. The LED of the dongle is constantly glowing during the reboot process, but xow won't connect to it anymore afterwards. The only thing I can do then is to completely shutdown the machine and also cut the power cord off. When I then turn everything on again then it works as exepcted: The LED does not glow during the boot process and then after the boot process is finished it starts to glow and then it works.

As SteamOS is based on Debian, you could try to add the Debian package repositories to your system (no idea how to do this). Oh, and by the way, libusb 1.0.19 is around 5 years old smile.

Yea because SteamOS is based on Debian 8 Jessie (latest is Debian 10 Buster), which is already 5 years old
unfortunately Valve doesn't really update it anymore

there are also some weird issues due to the really old Debian version like some newer games not working (e.g. Dead Cells, Ruiner) due to the old glibc version or you loose potential performance improvements because of the very old nvidia drivers or older Mesa/Kernel for AMD users
not to mention the poor hardware support for anything released in the recent 5 years

Fortunately the community took care for alternatives:

• https://github.com/ShadowApex/steamos-ubuntu for a SteamOS like Ubuntu
• https://gamer-os.github.io/ based on a rolling release
• or install any newer linux distro and run Steam Big Picture at start, there is also a community updated steamos-compositor package available with more options than the original one from Valve at the moment if you want to tinker it even further

I'm really sorry for going a bit off topic here but making SteamOS up2date or viable with anything recent is just not worth the time at the moment

[offalynne]

you can ignore the git error but you need to update g++: sudo apt install build-essential

Hi,

thanks for your help, but unfortunately it still doesn't work:

To me, it seems that GCC / G++ in the SteamOS Repository is still too outdated for the xow sources, even after sudo apt install build-essential:

Is there anything I could do (assuming that I want to stay on SteamOS and not install any other OS on my Steam Machine)?

[medusalix]

I've just made some changes to make xow compatible with C++11 (which should be supported even by g++ 4.8). You should be able to build it now.

[andreashuetter]

Thank you, this is my output now after your latest changes (I am using g++ 4.9.2), the compilation process is going a little bit further now, but still spits out an error:

Edit:
This link
https://lab.louiz.org/louiz/biboumi/commit/a195939cdaca343013d32ae902839ffdb28c33cb
suggests to use strftime instead of put_time to be compatible with gcc 4.9.

[medusalix]

It seems like std::put_time was not implemented until g++ 5.0. You could just remove the line where it's failing (it's just for printing out the time when logging occurs).

[andreashuetter]

OK, I just commented this line out in utils/log.cpp
//stream << std::put_time(&localTime, "%F %T");
as you suggested, and now it compiles!

But when I plug in my dongle and launch the xow executable, it crashes immediately with a segmentation fault.

sudo dmseg gives the following output:

I thought the firmware.bin that is included in the xow sources would contain the appropriate firmware and that it would be linked into the executable automatically at compile time? Or does the dmesg output mean that I need to download the specific mt76x2u firmware vom mediatek and copy it to /lib/firmware?

[medusalix]

I thought the firmware.bin that is included in the xow sources would contain the appropriate firmware and that it would be linked into the executable automatically at compile time?

Yes, that's absolutely correct. The output in dmesg is actually related to Linux' built in mt76 kernel driver. It conflicts with xow, leading to its crash. Please try adding this piece of code right before the call to libusb_claim_interface:

libusb_set_auto_detach_kernel_driver(handle, true);

[andreashuetter]

Well, for some reason it still does not work.

I also added

libusb_set_auto_detach_kernel_driver(handle, true);

in dongle/usb.cpp, just before error = libusb_claim_interface(handle, 0);

Then I did

I did some additional testing on my Desktop PC (running Manjaro Linux 18) and there I got the new, smaller dongle to run (even without the above mentioned SteamOS specific workarounds):

The older, bulkier one crashes on Manjaro with

On SteamOS still, with both types of dongles I don't get far:

[medusalix]

I think the version of libusb you have installed on SteamOS probably contains some kind of bug. You should probably try to get a newer version.

[andreashuetter]

Which version of libusb would be appropriate for xow?

On SteamOS initially when I tried to compile xow I got the message "libusb.h" not found, so I installed

sudo apt-get install libusb-1.0-0-dev

Maybe that version is outdated.

On Manjaro 18 on the other hand I didn't need to install libusb, because it was already there. But when I perform a find command to determine which version is present there, it seems to be the same:

[andreas@erazor ~]$ sudo find / -name "libusb*"

[medusalix]

That's not the actual version of the package though. You should run dpkg -s libusb-1.0-0-dev to see the installed version. I'm running libusb 1.0.23-1.

[andreashuetter]

OK, seems that SteamOS has libusb 1.0.19-1.

What's the best way to obtain a newer version if this is the only version in the SteamsOS repository? Download the sources from https://github.com/libusb/libusb and compile them manually?

As SteamOS is based on Debian, you could try to add the Debian package repositories to your system (no idea how to do this). Oh, and by the way, libusb 1.0.19 is around 5 years old 😄.

@Der-Eddy Thanks for the writeup, I'm sure this will help people with similar issues in the future.

@andreashuetter Awesome 😃. I've pushed a commit (d0341e4) that should fix your reboot issue.

[andreashuetter]

Thanks a lot, but there are 2 issues:

1. To compile the new version it was necessary again to edit utils/log.cpp and comment out the line
   stream << std::put_time(&localTime, "%F %T");
   It is quite annoying to manually comment out this particular line every time I want to test a new version of xow.
   Would it be possible to use strftime instead of put_time (as suggested here https://lab.louiz.org/louiz/biboumi/commit/a195939cdaca343013d32ae902839ffdb28c33cb) to make it compilable even on SteamOS (gcc 4.9)?

2.The line
libusb_set_auto_detach_kernel_driver(handle, true);
is still missing in dongle/usb.cpp (right before the call to libusb_claim_interface).
Is this line suppossed to be added manually every time when a new version is pushed?
Or were there any other changes made, so this line should not be needed to be added any more?

1. I don't want to go back to raw C strings just to make strftime work (and hardcode the string length). I think C++11 is a reasonably old standard to tailor the code to. You could always make yourself a git patch and apply that whenever you run xow.

2. I'm not sure if that's even needed anymore. I only assumed it would solve your problems, please try running xow without it.

[andreashuetter]

Well, I made some addtional tests now.

With the new (smaller) dongle the reboot issue seems to be fixed now. Great work!
Even the line
libusb_set_auto_detach_kernel_driver(handle, true);
doesn't seem to be needed anymore in dongle/usb.cpp.

But the older, bulky dongle doesn't seem to work reliably with the latest version of xow anymore. I will do more testing with the current version and with the previous version to get more into detail.

As for the put_time / strftime issue in log.cpp - may I suggest to handle this with a preprocessor directive, something like this?
#if __GNUC__ > 4.9 ...
