conan-io/conan-center-index#17142 (comment) (and this is for arch=x86_64)

Apologies you are experiencing this - the QtWebEngine is not built by default by our CI service (it's unlikely it's required by most users and it does take considerable time and resources to build), so this configuration is less tested than the defaults.

same applies here

and it's not specific to riscv64. you will find the same issue with x86_64 etc. with same (new) version of fontconfig.

This issue also happens on linux-arm64

[jeromelaban]

It's working fine on linux-x64 for me though, maybe there's a variation in my setup that makes it work.

Looking further into this, the dependency is about libfreetype2 which requires 2.15 or later. My system is a RPi Debian bookwork which installs 2.14 at most and explains the error, specifically.

Edit: This is for risc, not the other targets, which require 2.13, which does not explain my error, after all.

https://github.com/search?q=FT_Get_BDF_Property+undefined&type=issues something tells me it's not the first time this error is seen, and not for a specific arch (reported against x64 and arm64). see @vejmartin comment microsoft/vcpkg#11985 (comment). so it depends on multiple factors, versions, how lib was built and system configurations of where it is being used.

I'm getting the same on a Raspberry Pi 3 using Bookworm (Raspbian) running arm64. The latest available libfontconfig1 version (via bookworm apt sources) is 2.14.1-4 (if the issue is actually related to that package/library).
