How can I symlink to the kernel source in "/lib/modules/'uname -a'/build"?

[danny]

Should I execute

Code: [Select]

./configure --host=arm-linux --prefix=/home/tc/workand compile Makefile in iw-4.14 and libnl-3.4.0 like

Code: [Select]

make mrproperor other instruction to compile them?

[Juanito]

You should do it like this:

Code: [Select]

CC="gcc -march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -Os -pipe" CXX="g++ -march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -Os -pipe -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local --localstatedir=/var --disable-static

find . -name Makefile -type f -exec sed -i 's/-g -O2//g' {} \;

make
sudo make install
..but why compile them when they already exist?

When I pasted

Code: [Select]

CC="gcc -march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -Os -pipe" CXX="g++ -march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -Os -pipe -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local --localstatedir=/var --disable-staticthen show

Did you load compiletc and are you compiling on an RPi?

[danny]

Thanks for help Juanito and Rich.
I have installed it successfully.
By the way,
Can I change default Wifi interface "wlan0" to another one on piCore?

[Juanito]

What are you try to do exactly?

If you wish to disable the built-in wifi on an RPi3, for example, you can add the following to /mnt/mmcblk0p1/config.txt:

Code: [Select]

dtoverlay=pi3-disable-wifi
Once the built-in wifi is disabled, the wifi.sh script from the wifi extension looks like it would detect rpine0 from your extenal adapter.

Edit: it also looks like "dtoverlay=disable-wifi" would disable the built-in wifi on both RPi3 and RPi4.
