How to build a static version of the pcap library for Arm Linux

I saw libpcap here https://github.com/the-tcpdump-group/libpcap?files=1

I have compiler for arm linux.

How can I build libpcap to a file so I can statically link to this lib in my project?

I didn't find MakeFile for Arm.

On Ubuntu 16.04 86_64 or later, assuming bison and flex were installed, and gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf.tar.xz was downloaded and extracted into the /opt directory, a possible procedure for cross-compiling the latest version from scratch would be:

wget https://github.com/the-tcpdump-group/libpcap/archive/libpcap-1.9.1.tar.gz
tar zxf libpcap-1.9.1.tar.gz
cd libpcap-libpcap-1.9.1
CROSS_COMPILE=/opt/arm/9/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf- CC=${CROSS_COMPILE}gcc ./configure --host=arm-none-linux-gnueabihf --prefix=$(pwd)/libpcap-1.9.1-arm-none-linux-gnueabihf
CROSS_COMPILE=/opt/arm/9/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf- CC=${CROSS_COMPILE}gcc make install

The libraries and include files will be installed in libpcap-libpcap-1.9.1/libpcap-1.9.1-arm-none-linux-gnueabihf:

ls -gG  -a libpcap-1.9.1-arm-none-linux-gnueabihf/include libpcap-1.9.1-arm-none-linux-gnueabihf/lib
libpcap-1.9.1-arm-none-linux-gnueabihf/include:

lrwxrwxrwx 1      12 Feb  6 13:07 libpcap.so -> libpcap.so.1
lrwxrwxrwx 1      16 Feb  6 13:07 libpcap.so.1 -> libpcap.so.1.9.1
-rwxr-xr-x 1  942752 Feb  6 13:07 libpcap.so.1.9.1
drwxr-xr-x 2    4096 Feb  6 13:07 pkgconfig

I hope this helps.

Just a remainder: Flex and Bison can be installed using:

sudo apt-get install flex bison
