Cross-Compiled Linux From Scratch - Version 1.2.0-PowerPC64-Multilib

Chapter 10. Installing Basic System Software

10.30. Pkg-config-0.26

Pkg-config is a tool to help you insert the correct compiler options on the command line when compiling applications and libraries.

10.30.1. Installation of Pkg-config

Prepare Pkg-config for compilation: 

GLIB_CFLAGS="-I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include" \
  GLIB_LIBS="-lglib-2.0" \
  CC="gcc ${BUILD64}" \
  ./configure --prefix=/usr \
    --with-pc-path=/usr/share/pkgconfig

The meaning of the new configure option:

GLIB_CFLAGS="-I/usr/include/glib-2.0 -I/usr/libi64/glib-2.0/include", GLIB_LIBS="-lglib-2.0"

Pkg-config no longer comes with Glib and because Pkg-config has not been installed itself it needs to be told where Glib is.

Compile the package: 

make

To test the results, issue: make check.

Install the package: 

make install

On multilib builds the library direcory has been removed from the default search path of pkg-config. Set some environment variables to help set the path correctly in the future: 

export PKG_CONFIG_PATH32="/usr/lib/pkgconfig"
export PKG_CONFIG_PATH64="/usr/lib64/pkgconfig"

Export these variables to prevent any issues in the future. 

cat >> /root/.bash_profile << EOF
export PKG_CONFIG_PATH32="${PKG_CONFIG_PATH32}"
export PKG_CONFIG_PATH64="${PKG_CONFIG_PATH64}"
EOF
