  • I actually tried PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig beforehand but it didn't work. after setting PKG_CONFIG_PATH still pkg-config --variable pc_path pkg-config prints usr/local Commented Jul 17, 2014 at 13:50

    Right -- you haven't changed the default path, but paths in $PKG_CONFIG_PATH are checked first. After you set it, you can check by calling, e.g. pkg-config --libs somepackage where "somepackage" has a .pc file in multiple places. Commented Jul 17, 2014 at 14:04
  • manpage says pkg-config retrieves information about packages from special metadata files. These files are named after the package, and has a .pc extension. On most systems, pkg-config looks in /usr/lib/pkgconfig, /usr/share/pkgconfig, /usr/local/lib/pkgconfig and /usr/local/share/pkgconfig for these files. It will additionally look in the colon-separated (on Windows, semicolon-separated) list of directories speci‐ fied by the PKG_CONFIG_PATH environment variable. so isn't there any way to exclude /usr/local/share/pkgconfig ?

  • No, but it doesn't matter if you prioritize the paths you want to prioritize. I've added an example of what I'm talking about to demonstrate that using $PKG_CONFIG_PATH works. Commented Jul 17, 2014 at 14:29
  • let me test your method again, I got library error while compiling this github.com/MaartenBaert/ssr.git I hope it works, I believe I tried your method and it didn't work Commented Jul 17, 2014 at 14:41
