Hi Adnan, Do you get the same types of errors (undefined reference to __wrap_fprintf, etc.) when using the MPI profile configuration method (that is, exporting MPICXX_PROFILE)? Let's troubleshoot that method first since it looks like you are getting further along with it. It at least seems to have the link line right, at first glance. FWIW, we typically "encourage" users to configure MPICH libraries to be built corresponding to the link method they want to use. So, in your case (static linking), it might simplify things to configure MPICH to only build its static libraries (using '--enable-static --disable-shared' on the configure line). That's not to say we can't get the static linking working using default configure options, just appears to be more difficult to get right. I can try playing around with my local MPICH build and darshan builds to see if I can get it working, and will let you know how if I do. Thanks, --Shane On 10/18/2017 06:10 PM, Adnan Haider wrote:
I have been trying the mpicxx -profile=/path/to/mpicxx-cxx.conf option since I have gotten further with this method, but here is the output for both:
when using mpicxx.darshan method:
g++ -o binary *.o darshan/simple.cc -I/home/adhaider/apps/mpich_install/include -L/home/adhaider/apps/mpich_install/lib -lmpicxx -Wl,-rpath -Wl,/home/adhaider/apps/mpich_install/lib -Wl, --enable-new-dtags -lmpi
* notice the above doesn't even have the darshan libs.
Now when using mpicxx -profile=/path/to/conf
g++ -o binary *.o darshan/simple.cc -I/home/adhaider/apps/mpich_install/include -L/home/adhaider/apps/mpich_install/lib -lmpicxx -lmpicxx -L/home/adhaider/apps/darshan_install/lib -ldarshan -lz -Wl,@/home/adhaider/apps/darshan_install/share/ld-opts/darshan-base-ld-opts -Wl,-rpath -Wl,/home/adhaider/apps/mpich_install/lib -Wl,--enable-new-dtags -lmpi -L/home/adhaider/apps/darshan_install/lib -Wl,--start-group -ldarshan -ldarshan-stubs -Wl,--end-group -lz -lrt -lpthread
Thanks in advance!

Can you provide the output of the linking stage with the generated mpicc. So if you named your mpicc, mpicc.darshan:
mpicc.darshan -show -o binary *.o
The previous post you mentioned has some type of error in the generated script where one of the compiler arguments was not being added properly.

Hi,
I am trying to statically instrument my application with darshan. I am using mpich 3.2 and darshan 3.1.4. I have also tried 3.1.3 and 3.0.0 all which give the same errors as this post: https://lists.mcs.anl.gov/mailman/htdig/darshan-users/2017-July/000448.html <https://lists.mcs.anl.gov/mailman/htdig/darshan-users/2017-July/000448.html>
Maybe I am not compiling mpich with the correct flags? ( I am not changing the defaults).
I get these errors for the example IO_simple.c as well as a very simple piece of MPI code.
Also nm libdarshan.a does show the functions that are coming up as undefined, same as the post I linked to.
Any help would be greatly appreciated.
