| Environment Variable can't be used [message #215420] |

Hello,
I've got a System Environment Variable which is called "include", and it
contains the path to all my include directories.
Now, I want to use this variable inside my project, so that other
developers can just use their own "include"-variable as well, but I can't
use it.
I went to Project Properties, C/C++ Build, Settings, GCC C++ Compiler,
Directories, and there I wanted to add "%include%", I also tried "include"
and "${include}" as well, but none of those were successful.
What am I doing wrong? Or isn't it possible at all?

Hi Christian,
If your variable contains only one path it works well for me (CDT 4.0.1
and 5.0.0)
Simply add the variable to the path&symbols page e.g. ${include} and it
will also appear in the compiler settings and includes-folder.
You have to add each include path and not a list of all paths.
e.g. include=/usr/include:/usr/lib/include
this will expand to the gcc argument -I/usr/include:/usr/lib/include

Hello,
thanks for your answer! Well, I haven't got a "path&symbols" page (at
least I can't find it), I have got "C/C++ Build" - "Environment", and
there are three variables defined (PWD, CWD, PATH). I can also click
"Select..." and then add my system variable "include", but I can't then
use it inside "C/C++ Build" - "Settings" - "Tool Settings" - "GCC C++
Compiler" - "Directories".
I'd like to just use this "INCLUDE" variable there, but I have to specify
the paths directly. For a single developer this might not be a problem,
but since I'm doing this project with someone else, it would be cool if he
could just use his own INCLUDE variable as well, with a different content.
