I am trying to build a project that contains links to external files but the builder does not seem to be able to find them.

Here is an example:

- Start Eclipse/CDT
- Create projects P1 and P2
- In project P2 create C++ Header File sample.h
- Select the P1/src folder (where the P1.cpp file with main is)
- Select New -> Other -> General -> File
- Click Advanced and tick "Link to file in the file system"
- Click Variables, select WORKSPACE_LOC and click Extend
- Browse and select P2/sample.h
- Now the C/C++ Projects tab shows the link to sample.h right next to P1.cpp
- Edit P1.cpp and add the line: #include "sample.h"
- Try to build project P1
- It says:

Quote:

make all
Building file: ../src/P1.cpp
Invoking: GCC C++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/P1.d" -MT"src/P1.d" -o"src/P1.o" "../src/P1.cpp"
../src/P1.cpp:11:20: error: sample.h: No such file or directory
make: *** [src/P1.o] Error 1

Is there a way to have sample.h provided to g++, other than giving up on links and copy (duplicate) the P2/src/sample.h file into the P1/src folder?
