10.35. Pkg-config-lite-0.28-1

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

10.35.1. Installation of Pkg-config-lite

Prepare Pkg-config-lite for compilation: 

CC="gcc ${BUILD64}" ./configure \
    --prefix=/usr \
    --docdir=/usr/share/doc/pkg-config-0.28-1 \
    --with-pc-path=/usr/share/pkgconfig

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
