GCC Error
Hi, I'm trying to install some tools to make a WiFi card support monitor mode
https://github.com/radxa/rkwifibt/bl...ols/dhd_priv.c
To install them i was told to use the command
Code:
gcc dhd_priv.c -o dhd_priv
and that i would need gcc 7 to do so which i have installed.
However when running the command i just get loads of error's, can any give me any pointers please.
This is the start of the errors, sorry i cant post it all due to the limitation of characters per post.
Code:
root@rockpi-4b:~# gcc --version

that is not an error message, just a warning. I think you can check your app is ready to use

I don't see any notes on this at all

You are going to have to understand what this is doing, where the inputs come from, and why.
Where did you get the notes from to compile and run this? If you want help, you are going to have to give a lot more info.

Hi @Teckk, thanks for the info.
The problem i have is missing info unfortunately so all i have to go by is error messages.
To back track a little, i have a Rockpi 4B board which has onboard WiFi running Armbian 22.05 which is a version of Ubuntu.
The onboard WiFi is supposed to support monitor mode which is what this code is supposed to enable.
The only instruction i have to follow is from this page - [URL="https://wiki.radxa.com/Rockpi4/dev/monitor-mode"]https://wiki.radxa.com/Rockpi4/dev/monitor-mode[/URL
However the link provided is dead so the support team there told me to use the Github link -
https://github.com/radxa/rkwifibt/bl...ols/dhd_priv.c
Originally when i tried to compile the C code i got an error so was advised to use gcc 7 which i have done.
That's pretty much where i have managed to get to, once compiled i get the messages mentioned above and then if i continue ( based on the suggestion of them being warnings ) i get the other error previously mentioned.
As you may have guessed i'm no Linux Guru so not sure really where to go next, however one thing that does bug me with the C Code is there is several mentions of Android and nothing that suggests what interface i will use for the monitor mode, i.e. wlan0
I'm 100% sure if this code is even for Ubuntu.
