glib <=2.7 not found

[edgarriba]

hi! I'm attempting to build a cross docker for an old ubuntu18.04 that needs gstreamer with glib <= 2.7 and I'm getting some issue to get the container with the right configuration. This is what I'm trying

FROM ghcr.io/cross-rs/aarch64-unknown-linux-gnu:0.2.5

RUN apt-get update && apt-get install --assume-yes \
    cmake \
    curl \
    libglib2.0-dev \
    pkg-config \
    && \
    apt-get clean

RUN dpkg --add-architecture arm64

RUN apt-get update && apt-get install --assume-yes \
    nasm \
    libgstreamer1.0-dev:arm64 \
    libgstreamer-plugins-base1.0-dev:arm64 \
    libssl-dev:arm64 \
    libglib2.0-dev:arm64 \
    libudev-dev:arm64 \
    && \
    apt-get clean

Then during the compilation I get the following error:

  cargo:warning=
  pkg-config exited with status code 1
  > PKG_CONFIG_PATH=/usr/lib/aarch64-linux-gnu/pkgconfig/: PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags glib-2.0 glib-2.0 >= 2.56

  The system library `glib-2.0` required by crate `glib-sys` was not found.
  The file `glib-2.0.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/aarch64-linux-gnu/pkgconfig/
      - 

  HINT: you may need to install a package such as glib-2.0, glib-2.0-dev or glib-2.0-devel.

Not sure why it doesn't work. After installing libglib2.0-dev:arm64 glib-2.0.pc should exist.

If you enter the image you created, does the file exist?

(also, this doesn't seem like a cross issue, but I can try to help you :) )

hi @Emilgardis, it definitely exists with pointing v2.48.2.

i'm trying to compile the same code outside of cross and it succeeds without a problem but I have the issue that I need to match with glib 2.56.4 with ubuntu 18.04 if I want to use cross (which will save me a lot of compilation time).

Tried to made explicit the version but apt it fails by not finding it.

RUN apt-get update && apt-get install --assume-yes \
    nasm \
    libgstreamer1.0-dev:arm64 \
    libgstreamer-plugins-base1.0-dev:arm64 \
    libssl-dev:arm64 \
    libglib2.0-dev:arm64=2.56.1-2ubuntu1 \
    libudev-dev:arm64 \
    && \
    apt-get clean

not sure why it can't find it, I'm not very good at ubuntu packages so not sure what else you could try :/
