Include another folders into eclipse projects [message #1830587]

Hi, all.

Currently I have 2 eclipse projects (by simplify I called them Proj-A and Proj-B) and they are both compile/build-able, and both projects are in separate workspaces.

Now, I created a new folder, called Common (out from either workspaces, just a new folder) and there are common.c and common.h

Simple illustration of the folder structure as below

<C>
+---Proj-A (workspace)
|
+---Proj-B (workspace)
|
+--- Common +--- common.c
+--- common.h

Can I know if it possible to include source path/library path (C:\Common) from File System into Proj-A and Proj-B and build?

The idea is Common folder will include all the common files that later being used by Proj-A and Proj-B...

Thanks and regards,
Weelian.

There are a couple of ways to achieve this.

1) link to directory Common in each project

The link can be a system link or an Eclipse simulated link.
The latter is made with File --> New --> Folder
and selecting Link to alternate location under Advanced

Eclipse will then act as if the common code is part of each project.

2) create a common library and link to it in Proj-A and Proj-B

You will need to tell both Proj-A and Proj-B where the common header files are.
This means setting the path to it in Project --> Properties --> C/C++ General --> Preprocessor Include Paths, Macros etc.
and, if you are using a managed build,
in the Include settings for each compiler in Project --> Properties --> C/C++Build --> Settings --> Tool Settings tab
