(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! -- ERROR MESSAGE -- Linking CXX executable ../bin/test_libmesh CMakeFiles/test_libmesh.dir/source/test_libmesh.cpp.o:(.rodata._ZTVN7libMesh6FEBaseE[vtable for libMesh::FEBase]+0x68): undefined reference to `libMesh::FEBase::compute_map(std::vector<double, std::allocator<double> > const&, libMesh::Elem const*)' CMakeFiles/test_libmesh.dir/source/test_libmesh.cpp.o:(.rodata._ZTVN7libMesh6FEBaseE[vtable for libMesh::FEBase]+0x70): undefined reference to `libMesh::FEBase::compute_affine_map(std::vector<double, std::allocator<double> > const&, libMesh::Elem const*)' collect2: ld returned 1 exit status make[3]: *** [../bin/test_libmesh] Error 1 make[2]: *** [CMakeFiles/test_libmesh.dir/all] Error 2 make[1]: *** [CMakeFiles/test_libmesh.dir/rule] Error 2 make: *** [test_libmesh] Error 2 -- TEST PROGRAM -- //#include "fe.h" //#include "kelly_error_estimator.h" using namespace libMesh; // Begin main function int main (int argc, char** argv){ LibMeshInit init (argc, argv); } Andrew E.

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 On Wed, May 2, 2012 at 1:54 PM, Roy Stogner <[email protected]> wrote: On Wed, 2 May 2012, Andrew E Slaughter wrote: I was experiencing some linker issues after re-building libMesh. I have the following test program that gives me an error when linking, if I remove the "kelly_error_estimator.h" include the program compiles and links fine. I also get the exact error if I include the "kelly_error_estimator.h" instead of the "fe.h". Do the apps and example programs link for you? What linker and command line options are you using for the test program? --- Roy ------------------------------------------------------------------------------ Live Security Virtual ConferenceExclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
