[BUG] [chip-tool] cannot build for armhf (32bit ARM)

[mmt-10]

Reproduction steps

I tried cross build for armhf on Ubuntu 22.04 x86_64.

As a prerequisite, I added ports.ubuntu.com to /etc/apt/sources.list.d/ports_armhf.list.

$ sudo dpkg --add-architecture armhf
$ sudo apt update
$ sudo apt install crossbuild-essential-armhf
$ sudo apt install libssl-dev:armhf
$ sudo apt install libglib2.0-dev:armhf
$ cd ${MATTER_SDK}
$ source scripts/activate.sh
$ cd examples/chip-tool
$ gn gen out/debug --args='target_os="linux" target_cpu="arm"'
$ ninja -C out/debug

LOG chip-tool-armhf-build.log

/usr/lib/x86_64-linux-gnu/glib-2.0/include/glibconfig.h

I set target_cpu="arm", but ninja accessed x86_64-linux-gnu directory.

and it maybe root cause is 64bit variable.

Can I resolve it?

resolve it

$ export PKG_CONFIG_PATH="/usr/lib/arm-linux-gnueabihf/pkgconfig"

Right, the glib path comes from pkg-config, and that will do what you tell it to do....

@mmt-10 , can you show the full content of ports_armhf.list and sources.list files? Thank you very much.

[mmt-10]

I'm sorry, I had vacation.

Please refer to below quote. ports_armhf.list is here.

However, I gave up on cross-build. because, I cannot resolve the library(glibc3.0 and etc) dependencies for the target board. If you can resolve the library dependencies, please let me know.
