V4L-Utils & Vitis 2021.2 Build Instructions

Question

I'm trying to build V4L-Utils using the instructions

System:

Vitis 2021.2,
Ubuntu 20.04.4 LTS

Setup:

~$ source /tools/Xilinx/Vivado/2021.2/settings64.sh
~$ source /home/max/petalinux/2021.2/settings.sh
~$ export INSTALL_PREFIX=/usr
~$ ./configure --prefix=$INSTALL_PREFIX --host=arm-linux-gnueabihf --without-jpeg --with-udevdir=$INSTALL_PREFIX/lib/udev
 
...

~$ make 
...
  CC       libdvbv5_la-dvb-dev.lo
dvb-dev.c:19:10: fatal error: libudev.h: No such file or directory
   19 | #include <libudev.h>
      |          ^~~~~~~~~~~
compilation terminated.

I can confirm i have the /usr/include/libudev.h on my system...

The instruction is tied to the Xilinx Software Development Kit (SDK), so the question is how to build V4L-Utils with Vitis, if at all possible.

does the path to the "missing" file have to match the --with-udevdir configure option? — , May 16 '22 at 11:55
@user_1818839 Hi, the /usr/lib/udev folder exists. Or what do u mean? — Max, May 17 '22 at 08:53

I found a solution

~$ export INSTALL_PREFIX=/tools/Xilinx/Vitis/2021.2/gnu/aarch32/lin/gcc-arm-linux-gnueabi/cortexa9t2hf-neon-xilinx-linux-gnueabi/usr
~$ ./configure --prefix=$INSTALL_PREFIX --host=arm-linux-gnueabihf --without-jpeg --with-udevdir=$INSTALL_PREFIX/lib/udev
~$ make -j16
~$ make install DESTDIR=$INSTALL_PREFIX
