Hello,
I'm just beginning to combine several files from my work into a more
cohesive whole. To do this I'm trying to modularize the code and am thus
taking a first stab at linking a user-defined library to deal.II.
I have the following in my CMakeLists.txt:
CMAKE_MINIMUM_REQUIRED(VERSION 3.16.3)
FIND_PACKAGE(deal.II 9.2.0 REQUIRED)
DEAL_II_INITIALIZE_CACHED_VARIABLES()
PROJECT(myproject)
ADD_LIBRARY(les ./Helper/BlockHelpers.cpp ./Solvers/direct_solver.cpp
./Models/ADM.cpp)
DEAL_II_SETUP_TARGET(les)
ADD_EXECUTABLE(channel_flow ./Test_Cases/turbulent_channel.cpp)
DEAL_II_SETUP_TARGET(channel_flow)
target_link_libraries(les)
This seems to match the CMake documentation example. However, upon running
'make les' I immediately get the following error while it's compiling
BlockHelpers.cpp:
error: expected class-name before ‘{’ token
regarding this class definition in the associated header, BlockHelpers.hpp:
template< typename MatrixType, typename VectorType>
class SystemMatrixWrapper : public Subscriptor
{
//class def
...
}
As far as I can tell, this issue is being caused by an issue linking to the
deal.II files and thus the compiler does not recognize Subscriptor as a
class. When I comment out ': public Subscriptor' this error disappears.
The file does include the subscriptor class with the line:
#include <deal.II/base/subscriptor.h>
about which the compiler/preprocessor does not complain.
How can I resolve this issue? Any advice would be most appreciated. I
suspect there is an issue with my CMakeLists.txt file.
