Compilation errors on AArch64 (Raspberry Pi 4 / Fedora 32)

[maxnatt]

Greetings,

Thanks for your work first of all. I am using Fedora 32 (aarch64 build) on the Raspberry Pi 4 and have troubles with compiling the driver.

I have pulled latest commit of the realtek-4.4.x branch at the time of writing this issue and changed Makefile in an appropriate way (CONFIG_PLATFORM_ARM_AARCH64 = y and CONFIG_PLATFORM_I386_PC = n).

Here's my uname:

Linux box 5.6.2-301.fc32.aarch64 #1 SMP Tue Apr 7 18:10:18 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

Here's make output (same when using dkms):

make

Is there any way this can be resolved?

I can't reproduce your error. Please check my logs in order to find the difference between environments. https://travis-ci.org/github/CGarces/rtl8192eu-linux-driver/jobs/677905059

I'll send a PR to add the missing CONFIG_PLATFORM_ARM_AARCH64 https://github.com/CGarces/rtl8192eu-linux-driver/blob/arm_64/Makefile#L134

I'm curious why are there gcc errors about command line options in your build log. 🤔

AFAIK I had the same errors only when specifying wrong architecture (e.g. when using CONFIG_PLATFORM_ARM_RPI = y instead of CONFIG_PLATFORM_ARM_AARCH64) on the Fedora aarch64, so currently build fails later when compiling files provided in the make log.

Makefile fixed at 4868187fe6fa72960bea38adb64a2ac7b92bd9f0 Ping @ertug that made the original patch

[maxnatt]

Unfortunately I haven't got time to test stuff again and I was able to compile and use driver from clnhub/rtl8192eu-linux repository without any issues, so closing the issue.

Opps, I haven't see that... /bin/sh: 1: bc: not found

Will check.

In any case, there is a problem with CONFIG_IOCTL_CFG80211. In this line https://github.com/Mange/rtl8192eu-linux-driver/blob/8ee79ecf880639b710a8cc7dc2dc6c39d372c857/include/sta_info.h#L482

Looks like in your compilation CONFIG_IOCTL_CFG80211 is not defined... but I don't know why. I'll reopen the issue.
