Eclipse c++11 support. how to.

http://stackoverflow.com/questions/32642375/eclipse-cdt-indexer-does-not-fully-recognize-c11

1.
Go to Project->properties->C/C++ General->Preprocessor Include Paths.    Click the Providers tab.
    Click CDT GCC Built-in Compiler settings
    Click Move Up button on the right.
    Under Language Settings Provider Options
        Click off Use Global provider shared between projects
        Add -std=c++1y to the end of the command line in Command to get compiler specs.

Step 2 gets the compiler working

    Go to Project->properties->C/C++ Build->Settings.
    Go to Tool Settings tab.
    Expand GCC C++ Compiler
    Click Dialect Pick the C++ Standard you wish to target from the Language Standard drop-down.

2. (if needed)
    add under Project > Properties > C/C++ Build > Settings then on the Tool Settings tab GCC C++ Compiler > Miscellaneous the -std=c++11 flag,

    then under Window > Preferences > C/C++ > Build > Settings on the Discovery tab chose CDT GCC Built-in Compiler Settings and add the -std=c++11 flag to Command to get compiler specs. On my machine it looks like this after the change:

    ${COMMAND} -E -P -v -dD -std=c++11 "${INPUTS}"

    clean and rebuild both your project and your index (Project > C/C++ Index > Rebuild) as Eclipse tends to cache error messages and show them even though they are gone after changing the settings.

$sudo ./b2 install

update LD_LIBRARY_PATH by using ldconfig command.
$sudo ldconfig


Setting Eclipse for Boost library,


ex)
GCC C++ Compiler -> properties -> C/C++ Build -> Settings -> includes -> path/to/installation/prefix/include
GCC C++ Linker -> Libraries serch path -> path/to/installation/prefix/include
GCC C++ Linker -> Libraries-> add 'boost_system'

How to change gedit's active tab color to make easy to verify current tab.

For Ambiance theme, find gtk-widgets.css for Ambiance theme.

mine is in below directory,
/usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css

edit the file with root permission.

~$ sudo gedit /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css


find below line from the file.

/* give active tab a background, as it might be dragged across of others when reordering */
.notebook tab:active {
    background-color: @bg_color;
}


change color to something else, for me I put some shade so active tab will be darker than others.

/* give active tab a background, as it might be dragged across of others when reordering */
.notebook tab:active {
    background-color: shade (@bg_color, 0.82);
}
