  The system library `gdk-3.0` required by crate `gdk-sys` was not found.
  The file `gdk-3.0.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/x86_64-linux-gnu/pkgconfig
      - /usr/lib/x86_64-linux-gnu/pkgconfig

  HINT: you may need to install a package such as gdk-3.0, gdk-3.0-dev or gdk-3.0-devel.

PKG_CONFIG_PATH 경로 문제 때문에 생긴 일.

해결법

export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/share/pkgconfig

# 1. 현재 PKG_CONFIG_PATH 확인
echo $PKG_CONFIG_PATH

# 2. gdk-3.0.pc 파일 위치 확인
find /usr -name 'gdk-3.0.pc' 2>/dev/null

# 3. pkg-config가 gdk를 찾을 수 있는지 테스트
pkg-config --libs --cflags gdk-3.0

sudo apt install -y \
    x11proto-dev \
    libx11-dev \
    libxrender-dev \
    libxext-dev

# 설치 후 확인
pkg-config --libs --cflags gdk-3.0
