With Eclipse: How to add include paths and libraries for all your C/C++ project

Question

Is it possible to add include paths and libraries to all C/C++ projects? In others words: How can I make them global or copy one C/C++ project build setting to another one?<

Answer 1

Semi-automagically, it can be done using this perl script:

#!/usr/bin/perl

# pipe the (gcc) compile command into this script
# It emits listOptionValue lines to paste into .cproject
#
# To easily find the paste location, set the include path as usual to a string 
# that is easily recognizable in the .cproject, e.g. to "MARKER_INCLUDE_PATH".
#
# Make sure eclipse is not running while you do these sorts of hacks and backup 
# your .cproject before.
# -----------------------------------------------------------------------------------------
# sample line: <listOptionValue builtIn="false" value="/usr/include/gdk-pixbuf-2.0"/>

while (<>) {
    @include_options = m#-I *(.*?) #g;
    print join ("\n", @include_options) . "\n";
    print join ('"/>' ."\n" . '                                 <listOptionValue builtIn="false" value="', @include_options);
    print '"/>' . "\n";
}

For Eclipse Indigo: There is no possibility to define globally include paths and libraries. But you can export and import them from one project to another.

Go to Project > Properties > C/C++ General > Paths and Symbols Then click Export Settings... to save the include paths and/or symbol definitions to a file. In your other project, you can then use Import Settings...
