Fix build for raspberry pi with cross #5272

task-jp · 2024-05-19T15:11:22Z

slint needs openssl to build it.

The system library openssl required by crate openssl-sys was not found. The file openssl.pc needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory. PKG_CONFIG_PATH contains the following:
- /usr/lib/arm-linux-gnueabihf/pkgconfig

HINT: you may need to install a package such as openssl, openssl-dev or openssl-devel.

I think adding this to the container is fine (no harm), but I don't think it's a general requirement on the target. Or am I missing something here?

armhf looks wrong here, shouldn't it be arm64?

Hmm no. Slint itself doesn't require OpenSSL on the target. I think maybe one of the examples (the energy monitor). But it's not a general build requirement of Slint.

I see there are other example specific items there, so no harm then:)
