Failed to build Aravis for Arm64 by crosscompile

[hankfumail]

Describe the bug When I built Aravis for Arm64 on Unbuntu 18.04 of X86 , it says there is no file "X11/Xlib.h", "zlib.h", "unicode/ucnv.h". How to specify sysroots directory?

To Reproduce Steps to reproduce the behavior: Environments: Unbuntu 18.04, Xilinx PetaLinux 2021.2, Xilinx ZynqMP Common image 2021.2, Aravis 0.8.20

I created an crosscompile configuration file.

[binaries]
# /opt/Xilinx/Vitis/2021.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc
c = '/opt/Xilinx/Vitis/2021.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc -sysroot=/opt/Xilinx/peta/2021.2/sdk_zynqmp/sysroots'

ar = '/opt/Xilinx/Vitis/2021.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-ar'
strip = '/opt/Xilinx/Vitis/2021.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-strip'
pkgconfig = '/usr/bin/pkg-config'
cmake = '/opt/Xilinx/Vitis/2021.2/tps/lnx64/cmake-3.3.2/bin/cmake'
ld = '/opt/Xilinx/Vitis/2021.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-ld  -sysroot=/opt/Xilinx/peta/2021.2/sdk_zynqmp/sysroots'
#pcap-config = ''

skip_sanity_check = true
sys_root = '/opt/Xilinx/peta/2021.2/sdk_zynqmp/sysroots'
root = '/opt/Xilinx/peta/2021.2/sdk_zynqmp/sysroots/cortexa72-cortexa53-xilinx-linux'

[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'aarch64'
endian = 'little'

[target_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'armv8a'
endian = 'little'

Then I execute the following commands to build Aravis.

 meson arm64-build --reconfigure  --cross-file meson-cross-arm64.txt
 ninja -C arm64-build

I got the following error.

I aslo export variable "PKG_CONFIG_SYSROOT_DIR" by command "export PKG_CONFIG_SYSROOT_DIR=/opt/Xilinx/peta/2021.2/sdk_zynqmp/sysroots". Then I still got same error.

I can find those files in the sysroots directory.

Expected behavior I hope to compile Aravis for Arm64 of Xilinx MPSoC ZCU106 board.

Hi,

pkgconfig = '/usr/bin/pkg-config'

Isn't there a pkg-config in /opt/Xilinx ? If so, I guess you should use this one.

[EmmanuelP]

It looks like there is no need to use a cross compilation specific pkg-config.

Looking at meson documentation, you should use at least meson 0.54, and use pkg_config_libdir and sysroot properties to specify the cross root environment directories.

[hankfumail]

It seems that we need "pkg-config" because I always has the following error. It is weird that I did get this error yesterday.

You have said you are compiling on an x86 machine. Is that the right declaration for the host machine ? Tha would explain why meson did not find pkg-config for HOST.

Hi, we've successfully cross-compiled Aravis v0.8.19 for the zcu106 target. Here's how we did it.

Build machine : Ubuntu 20.04 on x86-64 Target machine: Xilinx MPSoC ZCU106 board

1. Install PetaLinux tools to /opt/petalinux
2. Create PetaLinux project to /home/ubuntu/petalinux-wok/xilinx-zcu106-2021.1
3. Source PetaLinux setting script in the terminal
   • source /opt/petalinux/setting.sh
4. Add dependent packages to the rootfs by petalinux-config -c rootfs command

5. Build and install petalinux SDK
   • petalinux-build --sdk && petalinux-package --sysroot
   • cross compilers will be installed to /home/ubuntu/petalinux-wok/xilinx-zcu106-2021.1/images/linux/sdk/sysroots/x86_64-petalinux-linux/usr/bin/aarch64-xilinx-linux
   • sysroot will be installed to /home/ubuntu/petalinux-wok/xilinx-zcu106-2021.1/images/linux/sdk/sysroots/cortexa72-cortexa53-xilinx-linux/
6. Source the environment setup script in the terminal
   • . /home/ubuntu/petalinux-wok/xilinx-zcu106-2021.1/images/linux/sdk/environment-setup-cortexa72-cortexa53-xilinx-linux
7. Install meson and ninja
   • python3 -m pip install --user meson==0.59.0 ninja
8. Create meson cross files to /home/ubuntu/.local/share/meson/cross/cortexa72-cortexa53-xilinx-linux

   • Without doing this, viewer/data/meson.build:11:0: ERROR: Tried to assign the invalid value "None" of type NoneType to variable. will be happen when running meson command. Not sure why this solves...
10. Clone and build aravis
    • git clone https://github.com/AravisProject/aravis
    • cd aravis && git checkout 0.8.19
    • ~/.local/bin/meson build --cross-file cortexa72-cortexa53-xilinx-linux
    • cd build && ninja

It looks like @mshr-h post is a solution to his issue. I'm closing it.

Thanks.
