compile fails with cfg80211 enabled #1

Hi, Came across this post on the internet http://marc.info/?l=fedora-list&m=142282197701463&w=2 and thought you will find it useful. A link on that page, https://github.com/pld-linux/rtl8812au, contains a number of patches. Out of curiosity I applied the linux-3.18.patch and was then able to compile your source without it failing. I then applied the warnings.patch and that reduces the number of warnings conciderably as below. |

Hi, I have been able to remove the final 4 warnings by applying 4 items from the update-cfg80211-support.patch from https://github.com/pld-linux/rtl8812au. I have create a complete patch that I have posted to Dropbox. The link is https://dl.dropboxusercontent.com/u/80256631/rtl8812AU.patch All I need to do now is work out how to add the code for 8821ua devices to get my EW-7811UTC device working :) :) |
That is indeed quite a good repo 👍
Maybe it's just adding your device ID to |
|
Unfortunately it's not as simple as just adding the device id to The EW-7811UTC is an 8821au device so needs the 8821au code adding in to your current code. |
|
Ah ok, I thought they shared the same code base. Ah well, it was worth a shot 😉 |
Just playing with the code atm ... and came across the following line in |
|
Yes, I tried that and the compile fails. I haven't looked at the source for a while but I think if you look at gnab's code you will see a number of files either having 8821au in the name or in a directory 8821au. |

Bummer. Also got 2 questions to which you may know the answer:
|

OK, just done a new git clone and compile and I had to comment out I tend to use make clean && make (or make -j6 on a Pi 2B) which gives Once upon a time I used to edit the make file as you have but I don't bother these days. As to which way is better I have no idea. However, the drivers I compile all generally appear to work OK, although I had problems with a mt7601 wifi module. Compiling on the Pi 2B for a Pi 2B the wifi module would cause the kernel to crash when booting, but cross-compiling on a Ubuntu 14.0.2 system and it worked fine. The same code compiled on a Pi 2B for a Pi 1 seemed to work fine. I have not been able to figure out what the problem was with the driver on the Pi 2B. I now tend to cross-compile the wifi modules I use, including the 8812au, because of the issue with the mt7601 driver, and anyway it is somewhat faster than compiling on the Pi. As for DKMS I'm not sure I even know what it is :) What you want to do sounds useful, though. |

OK, must take a look at it. |

Wooohooo \o/ With the current code, I got it to compile completely without warnings and with cfg80211 enabled on both my main PC (amd64) and on the Raspberry Pi 2! Then I unplugged my device ( Wooohooo \o/ |
While there's certainly overlap with this driver, a diff between my driver and https://github.com/Braklet/rtl8811AU_rtl8821A-linux also shows quite some difference. |
|
Also compiles without errors/warnings on a Pi 1B+ ... and works 😄 |
|
Whether it compiles or not I think may depend on the kernel version being compiled for and also the version of gcc being used. |
|
Just changed Pi's I compile on, cloned your source and now it compiles without errors. Using a newer version of gcc. Went back to the other Pi, re-configured linux with Think I may have messed up the linux source on the first Pi doing a git pull to update the source and forgot I did not re-configure it after updating the linux source. |
That could very well be true. |
|
I have just installed a fresh wheezy system on a RPi 1B (with my Net Installer). and copied a Rebooted (although not needed) and logged in as myself over SSH. As you can see, everything went perfect 😄 I then did And that seemed to have gone right. I then plugged in my wireless device ( When the system was booted up again I noticed that And saw there were a whole bunch of files with file size 0! |

@MrEngman I just found out why my driver won't work on your device: |

I tried to integrate support for 8821a in a new branch: https://github.com/diederikdehaas/rtl8812AU/tree/add-rtl8821a-support |

Found a new repo with VERY recent code from Realtek: https://github.com/Grawp/rtl8812au_rtl8821au \o/ |
|
That's the version I'm using :) It was sent it to me by someone who got it after talking to Edimax support I think. However, good to see it on github now. I've tried your update and after adding the USB ID for the EW-7811UTC it compiles and runs OK. No need to edit the Makefile to compile. FYI here's a patch with a few more USB ID's for 8812au and 8821au devices |
|
Excellent, thanks 👍 I probably won't maintain this driver much any more since I found the other one with much newer code. I'd likely 'steal' code from the other one ... and that seems like a waste of effort. I already submitted a pull request to the other repo 😉 |
Thanks to MrEngman for the list. #1 (comment)
|
@MrEngman @diederikdehaas Can you please clarify how to compile the driver with cfg80211 support? I couldn't find any option in the Makefile pointing towards that. |
several small fixes
