Thanks Matthias,
What I've tried is to
ADD_DEFINITION(-DSOURCE_DIR=${CMAKE_CURRENT_SOURCE_DIR}) in the
CMakeLists.txt in the test directory. I tried tesing SOURCE_DIR in *.cc
file like: std::cout << SOURCE_DIR << std::endl;
When I did "make", screen printout shows:
"<command line>:2:20: note: expanded from here
#define SOURCE_DIR /Users/GrillCheese/UCB/Research/xtrans/tests/mesh
Following that it has errors like:
*/Users/GrillCheese/UCB/Research/xtrans/tests/mesh/mesh_generator_01.cc:57:17:
**error: **expected expression*
std::cout << (SOURCE_DIR) << std::endl;
and
*/Users/GrillCheese/UCB/Research/xtrans/tests/mesh/mesh_generator_01.cc:57:17:
**error: **use of undeclared identifier 'Users'*
*<command line>:2:21: **note: *expanded from here
#define SOURCE_DIR /Users/GrillCheese/UCB/Research/xtrans/tests/mesh
and other same type of error saying "use of undeclared identifier 'xxx'"
where xxx can be GrillCheese, UCB, Research etc.
Anything obviously wrong to you?
Thanks,
Weixiong
