[Trilinos-Users] Problem with building thyraepetraext example

[Bartlett, Roscoe A]

Hello,

In the future, to avoid these problems, you might want to look at using the export makefile system provided by Trilinos.  When you install Trilinos, you should get the file Makefile.export.thyra put in INSTALL_DIR/include.  The variable THYRA_LIBS will then give you the correct link line in the right order.

Another suggestion is to just build and link the same example from within the Trilinos build tree and then copy and paste the link line echoed during the build process into your own home-grown makefile.

Cheers,

- Ross

I find the problem, libthyraepetraext depend on libthyraepetra , so in Makefile , -lthyraepetraext should be in front of -lthyraepetra.
Sorry for troubling , i should have looked at the thyraepetraext source file for help first~

Hi all,
     I come with a problem when i build "/packages/thyra/adapters/epetraext/example/model_evaluator".
     My building process is as follows.
     Copy the "ForwardSolveEpetraModelEval2DSimMain.cpp" and the related  .h and .cpp files to my own directory.
     I've got
"EpetraModelEval2DSim.cpp  EpetraModelEval4DOpt.hpp
 EpetraModelEval2DSim.hpp  ForwardSolveEpetraModelEval2DSimMain.cpp
 EpetraModelEval4DOpt.cpp  Makefile" in my work directory.

   When i make the project , the compiling process is correct while linking meets error. The libthyraepetraext.a cannot be linked correctly.
   The error msg is as follows:
