Link external source folder via environment variable [message #771437] Tue, 27 December 2011 08:51 Go to next message

Hi,

I'm trying to link external source folder to my project. I'm doing this via Project properties->C/C++ general->Paths and Symbols->Source Location->Link Folder.
In principle it is working fine, if I specify the absolute folder path.

The problem is that the absolute path is not applicable in my case, as we share the project via SVN, and other developers have that folder with absolute paths. We are using an environment variable to reference this issue. But this variable is not available in the "Variables.." popup for the linked resources. Only variables I see there are ECLIPSE_HOME, PARENT_LOC, PROJECT_LOC and WORKSPACE_LOC.

This puzzles me a lot. How can I link the folder using an environment variable? I can see the variables in the Project properties->C/C++ build->Build Variables (with "Show system variables" enabled), but not in Project properties->Resource->Linked Resources->Path Variables.

Are there any solutions to this problem?

Best regards,
Mikhail Barg

I think there is no solution in Eclipse.

But a solution for your problem could be to use "symbolic links" on each PC. Each developer must define such a link once. In your Eclipse configuration you can use this symbolic link.

For example, under Windows 7 you could define:

C:\SOURCE>mklink /d symlink C:\my\source\is\here

In Eclipse you can use this "symbolic linked folder":
C:\SOURCE\symlink

Klaus

Eclipse won't pick up Path Variables from Environment variables. You
can define your own Path Variables in the popup for linked resources.
Click on the New button and browse to the file system location. Each
developer then needs to define this variable in their own workspace.

You are able to get relative paths using special variable names that are
internal to Eclipse. You can setup the relative links using Drag and
Drop. Open up a system file navigator window (Explorer, Dolphin,
Nautilus, etc). Drag the external folder and drop it on the project in
the Eclipse Project Explorer. A dialog box will ask if you want to add
the folder to the project. Select Link to Files and Folders. You can
then select if the link should be relative to the project, workspace, or
a variable you create yourself.

Hi,

Thanks for all the responses! I figured the solution with every developer defining the linked resource variables for the workspace
(Preferences->General->Workspace->Linked resources), and then using this variables to link folders in a specific shared project..

Best regards,
