Description
Using the MacPorts gcc 4.3 or 4.4 compiler, the compilation of the test suite fails on Mac OS 10.6.
To compile with MacPorts gcc 4.4 compiler, I used
$ export CXX=g++-mp-4.4 $ export CC=gcc-mp-4.4 $ ./configure --disable-python-binding $ make $ make check
This led to the following error:
Making check in test make test_GSupport test_GVector test_GMatrix test_GSymMatrix test_GSparseMatrix test_GNumerics test_GFits test_GXml test_GApplication test_GModel test_GSky test_GOptimizer test_GObservation test_MWL test_CTA test_LAT make[2]: *** No rule to make target `test_GSupport-test_GSupport.', needed by `test_GSupport'. Stop. make[1]: *** [check-am] Error 2 make: *** [check-recursive] Error 1
Recurrence
No recurrence.

It turned our that the OBJEXT variable was not set to the object extension in the Makefile. The variable reads
OBJEXT =
Setting
OBJEXT = o
made the compilation work.
It remains to be understood why the OBJEXT variable is not set correctly.

Note that after fixing the above mentioned problem, another problem occurred. Compilation of the test_GObservation executable failed with the following message:
ld: duplicate symbol _gomp_thread_attr in ../src/.libs/libgamma.a(GTestSuite.o) and test_GObservation-test_GObservation.o for architecture x86_64 collect2: ld returned 1 exit status make[2]: *** [test_GObservation] Error 1 make[1]: *** [check-am] Error 2 make: *** [check-recursive] Error 1
This is due to the OpenMP section in test_GObservation.cpp:
#ifdef _OPENMP #include <omp.h> #ifdef __APPLE__ #ifdef __MACH__ #include <pthread.h> pthread_attr_t gomp_thread_attr; #endif #endif #endif
Note that a similar section exists in GTestSuite.cpp. I therefore deleted the corresponding section in test_GObservation.cpp.

The OBJEXT problem was also solved. The missing object extension was due to the Mac OS X clang kluge that has been introduced to make clang preceeding the gcc compiler in case that the system is Mac OS X >= 10.7.

The problem was a little bit more complex, as the Apple gcc compiler needs both inclusions, while the MacPorts gcc compiler did not like this.
I added a specific test to the configure script that checks the type of code that is needed. This sets then the compiler definition HAVE_OPENMP_DARWIN_KLUGE so that the respective code section can be written as:
#ifdef _OPENMP #include <omp.h> #ifdef HAVE_OPENMP_DARWIN_KLUGE #include <pthread.h> pthread_attr_t gomp_thread_attr; #endif #endif
Now the global variable gomp_thread_attr is only defined when it’s really needed.
