Issue compiling on Ubuntu 20.04 (Wireguard needed)

[tkndrm]

Hello, i have difficulties to compile the firmware on *ubuntu 20.04. My goal is to active wireguard support for my Dragino DLOS8 LoRa Gateway.

It would be very nice, if you guys can provide us with a sysupgrade.bin that comes with wireguard support.

So far i try to compile without modification of the config file

$ ./build_image.sh 

Remove custom files from last build
***Copy general_files to OpenWrt***
***.config.lgw to OpenWrt/.config***

***Find customized .config files***

Do i miss any requirements for the building/compiling process?

A friend managed to build for me a firmware that includes wireguard on Ubuntu 18.04 but unfortunately it didn't worked after flashing it to my DLOS8 Device.

It still gaves me errors:

# opkg install wireguard

Anyone an idea?

maybe you can patch like previous version m4 see the link : https://github.com/easybuilders/easybuild-easyconfigs/issues/8501

[nroach44]

Can confirm that https://github.com/easybuilders/easybuild-easyconfigs/issues/8501#issuecomment-503719143 fixes the freadahead compile issue

The second patch is also needed, and then the commands at the bottom of this link: https://bugs.archlinux.org/task/59782

sed -i 's/IO_ftrylockfile/IO_EOF_SEEN/' gl/lib/*.c
sed -i '/unistd/a #include <sys/sysmacros.h>' gl/lib/mountlist.c
echo "#define _IO_IN_BACKUP 0x100" >> gl/lib/stdio-impl.h #_IO_IN_BACKUP became private in glibc-2.28

... also editing openwrt/package/libs/libmpsse/Makefile PKG_SOURCE_URL to be https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/libmpsse/
