Subject: Re: [Libmesh-users] Problem linking... (fwd)

The problem has return. It returned when trying switching from the opt library to the dbg version. Yesterday it was working great, today I
switched to dbg to search for a problem and now I get this error. I completely removed libmesh and reinstalled and I still shows up, both in dbg
and opt.

For the test program below if I include either fe.h or kelly_error_estimator.h I receive the following error when linking. I am using the attached
cmake file to link and include the appropriate libraries.

Any help is greatly appreciated, this is driving me crazy!

       It is healed! I was writing the email below and gathering information
       and I fixed it, but I don't know how. I installed v0.7.2 and things
       worked fine, I then switched back to 0.7.3.1 for this response and the
       error was gone. I deleted 0.7.2 to make sure and it is still working.
       I don't know what was wrong, but it is working now.

       Just in case it show back up, this is the response to your email:

       I just ran the examples, with "make run_examples" and they all seemed
       to execute correctly. Everything was working fine yesterday, but a
       re-ran ./configure and it started doing misbehaving.

       I am using a cmake configuration that I made by looking at the
       Make.common file that libMesh generates, I attached the configuration
       file that specifies the libMesh related files to link and include
       (libMeshConfig.cmake). This file sets two variables:
       (1) LIBMESH_LIBRARIES a list of all the libraries from libMesh and
       (2) LIBMESH_INCLUDES a list of the libMesh include directories.

       Like I stated in a subsequent email, I received this error with
       v0.7.3.1 but did not with v0.7.2. The attached file is the
       configuration I used to get it linking with v0.7.2, but it is
       identical for v0.7.3.1 except the libfparser.so is not commented.

       I also link with PETSc, vtkIO, vtkCommon, vtkFiltering, tbb,
       tbbmalloc, and gfortran.

       I will start looking through the libMesh generated Make.common to see
       if I can find a missing include or link.

       Thanks for taking a look at this.
       -Andrew

             Do the apps and example programs link for you?  What linker and
             command line options are you using for the test program?
