[IGSTK-Developers] Problem with the testing program

[Patrick Cheng]

Hi Andinet,

I am having linking problem with the IGSTKLatestTests project.

igstkLatestTests error LNK2019: unresolved external symbol "int __cdecl 
igstkPolarisTrackerTest(int,char * * const)" 
(?igstkPolarisTrackerTest@@YAHHQAPAD at Z) referenced in function "void 
__cdecl RegisterTests(void)" (?RegisterTests@@YAXXZ)


The problem is: I built my IGSTK with IGSTK_TEST_POLARIS_ATTACHED
IGSTKSandbox use the configuration from the IGSTK.

So in IGSTKSandbox's igstkSystemInformation.h 
IGSTK_TEST_POLARIS_ATTACHED is being defined:
===================================================
#define IGSTK_TEST_POLARIS_ATTACHED
#define IGSTK_TEST_POLARIS_PORT_NUMBER \
     igstk::SerialCommunication::PortNumber2
===================================================
IGSTKLatestTests is using the this igstkSystemInformation.h file.


I think the problem is in IGSTKSandbox/Testing/CMakeList.txt
Line 184
===============================================================
IF(IGSTK_TEST_AURORA_ATTACHED OR IGSTK_TEST_POLARIS_ATTACHED)
   ADD_TEST(igstkNDICommandInterpreterTest ${IGSTK_TESTS} 
igstkNDICommandInterpreterTest)
ENDIF(IGSTK_TEST_AURORA_ATTACHED OR IGSTK_TEST_POLARIS_ATTACHED)

IF(IGSTK_TEST_POLARIS_ATTACHED)
   ADD_TEST(igstkPolarisTrackerTest ${IGSTK_TESTS} igstkPolarisTrackerTest)
ENDIF(IGSTK_TEST_POLARIS_ATTACHED)
===============================================================

The CMake variable IGSTK_TEST_POLARIS_ATTACHED didn't get the value from 
the IGSTK's CMakeCache.txt...

So the test is not being added and compiled.. meantime, it was being 
registered in the igstkTests.cxx

Thus there is a link error...
