Re: [bgl-discuss] Profile problem

[Anthony Chan <chan@xxxxxxxxxxx>]

being not familar with libmpitrace_c.a and C++ code, I'm guessing here:

If you are using ibm compiler, you shouldn't link to
/bgl/BlueLight/ppcfloor/blrts-gnu/powerpc-bgl-blrts-gnu -lstdc++,
which is for gnu compiler, not ibm compiler.
If your code is C++ code, shouldn't you use blrts_xlC ?

/soft/tools/mpitrace/libmpitrace_c.a seems to be compiled with xlc.
So you may want to try putting -L/soft/tools/mpitrace -lmpitrace_c before
-L/bgl/BlueLight/ppcfloor/bglsys/lib/ -lmpich.rts ....

I suggest to try the following in your link line:

blrts_xlC -I./include -I/bgl/BlueLight/ppcfloor/bglsys/include
-I/bgl/home1/jinxu/work/Hybrid/include
-qdebug=function_trace -o turbulence180e ./append.o ./polylib.o
./turbulence180e.o
/bgl/home1/jinxu/work/Hybrid/Hlib/Linux/liblapack_LINUX.a
/bgl/home1/jinxu/work/Hybrid/Hlib/Linux/libblas_LINUX.a
-L/bgl/home1/jinxu/work/Hybrid/Hlib/Linux -lvec -lfftw -lrfftw
-L/soft/tools/mpitrace -lmpitrace_c
-L/bgl/BlueLight/ppcfloor/bglsys/lib/ -lmpich.rts -lmsglayer.rts
-lrts.rts -ldevices.rts

If that does not work, append the link path below to the above command.

-L/opt/ibmcmp/vacpp/7.0/blrts_dev_lib
-L/opt/ibmcmp/vacpp/7.0/blrts_lib -libmc++
