[Trilinos-Users] MueLU example - compilation

[Martin Vymazal]

Hello,

  I can't link an example that is provided with Trilinos sources (source 
file name is Simple-Complex.cpp, trilinos 12.6.3) to Trilinos. My 
CMakeLists.txt is as follows:

CMAKE_MINIMUM_REQUIRED(VERSION 3.2 FATAL_ERROR)

project(MUELU_TEST CXX)

ADD_DEFINITIONS(-std=c++11)

SET( CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/cmake/modules" 
${CMAKE_MODULE_PATH})

list(APPEND CMAKE_PREFIX_PATH "$ENV{HOME}/local/gcc/openmpi")
find_package(MPI)
include_directories( ${MPI_CXX_INCLUDE_PATH} )


FIND_PACKAGE(Trilinos PATHS 
$ENV{HOME}/local/gcc/trilinos-12.6.3/lib/cmake/Trilinos )

SET(MY_SOURCES src/Simple-Complex.cpp)

INCLUDE_DIRECTORIES(${Trilinos_INCLUDE_DIRS} 
${Ttrilinos_TPL_INCLUDE_DIRS})
LINK_DIRECTORIES(${Trilinos_LIBRARY_DIRS} ${Trilinos_TPL_LIBRARY_DIRS})
ADD_EXECUTABLE(muelu_test ${MY_SOURCES})
TARGET_LINK_LIBRARIES(muelu_test ${Trilinos_LIBRARIES} 
${Trilinos_TPL_LIBRARIES} ${MPI_CXX_LIBRARIES})

and I see the following error (I pasted only the first part):

CMakeFiles/muelu_test.dir/src/Simple-Complex.cpp.o: In function `main':
Simple-Complex.cpp:(.text+0x7c2): undefined reference to 
`MueLu::Hierarchy<std::complex<double>, int, int,

std::char_traits<char>, std::allocator<char> > const&, 
Teuchos::RCP<MueLu::FactoryBase const> const&)'

To make sure that muelu is specified to link to the executable, I also 
tried

TARGET_LINK_LIBRARIES(muelu_test muelu muelu-adapters muelu-interface 
${Trilinos_LIBRARIES} ${Trilinos_TPL_LIBRARIES} ${MPI_CXX_LIBRARIES})

but this does not change anything. The libraries libmuelu.so 
libmuelu-interface.so and libmuelu-adapters.so are all present in the 
lib folder where Trilinos is installed. I have no problems compiling and 
linking other code (of my own, does not use MueLU) to Trilinos. Could 
you please advise how to resolve this? Thank you.

Best regards,

   Martin
