Hi,
I work as a software tester who has general understanding of C++
language.
I experiment with simulated Wi-Fi access point and a station.
My Linux distribution is Fedora 27.
I try to compile hostap by following the steps from:
https://wireless.wiki.kernel.org/en/users/documentation/hostapd#download_and_compile_hostapd
I get the source code from:
git://w1.fi/srv/git/hostap.git
I create a configuration:
cp defconfig .config
vi .config
Parameter "CONFIG_DRIVER_NL80211=y" is already uncomented.
make
../src/drivers/driver_nl80211.c:17:10: fatal error: netlink/genl/genl.h:
No such file or directory
#include <netlink/genl/genl.h>
^~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:1251: ../src/drivers/driver_nl80211.o] Error 1
When I search for file "genl.h"
then I don't find it on my system.
I search for package "libnl", but only "libnl3" is available.
I install it:
yum install libnl3 libnl3-devel
I repeat the previous compilation.
I receive the same error.
When I search for "genl.h"
then I find it in "/usr/include/libnl3/netlink/genl/genl.h".
The source file "../src/drivers/driver_nl80211.c"
includes "netlink/genl/genl.h".
To satisfy that requirement I create a soft link:
ln -s /usr/include/libnl3/netlink /usr/include/netlink
When I rebegin the compilation:
make clean
make
then I receive error:
/usr/bin/ld: cannot find -lnl
collect2: error: ld returned 1 exit status
make: *** [Makefile:1278: hostapd] Error 1
When I browse StackOverflow
and I search for "/usr/bin/ld: cannot find -lnl"
then I find article
"https://stackoverflow.com/questions/16710047/usr-bin-ld-cannot-find-lnameofthelibrary";.
When I follow the steps from that article
then I receive result:

QUESTIONS
1. What steps to follow in order to compile hostap?
2. Can you please update the documentation at
"https://wireless.wiki.kernel.org/en/users/documentation/hostapd#download_and_compile_hostapd";
to the latest release of Fedora?
