Build Fails for Kernel 5.4.55-1-lts (x86) Arch Linux

[randomguywithagun]

Used DKMS Installation Method with Kernel 5.4.55-1-lts (I know its not supported)
# dkms add .
# dkms build 8188eu/1.0 --kernelsourcedir /usr/src/linux-lts

didnt work, as apperently my kernel was 5.4.54-1 for some reason, while my headers where 5.4.55-1 so i did.

# pacman -Syu linux-lts linux-lts-headers

And got this error in /var/lib/dkms/8188eu/1.0/build/make.log

Replicated in Linux Mint 20, impossible to do a make all.
I needed to change to Kernel 5.1. Same thing there.

What I tried was compiling in my MX Linux 19.2 system because of this launchpad report about GCC-9.
MX Linux is pretty much "stable/older" so it would compile well due to the GCC version difference and effectively it did compile over Linux 4.19.

What I want to try now is to install that 5.1 Kernel in MX Linux then compile and then do the make install step in Linux Mint.

MX Linux 19.2

• GCC: 8.3.0
• Kernel: 4.19.0

Linux Mint 20

• GCC: 9.3.0
• Kernel: 5.4.0

I was able to get my rtl8188eus dongle working with this driver https://github.com/aircrack-ng/rtl8188eus
