Hello everybody,
I moving a makefile to cmake, and after errors I could check that order
in
link chain was important.
1) CMake generates this link.txt (error when linking)
/usr/bin/c++ -lfusion_io -ladios -lmxml -lmpi -lopen-rte
-lopen-pal
-lpthread -lstdc++ CMakeFiles/niio-main.dir/main.cpp.o -o niio-main
-rdynamic -L/home/testuser/dev/niio/lib
-L/home/testuser/dev/niio/openmpi/lib
2) Desired linking that works:
/usr/bin/c++ CMakeFiles/niio-main.dir/main.cpp.o -lfusion_io
-ladios
-lmxml -lmpi -lopen-rte -lopen-pal -lpthread -lstdc++ -o niio-main
-rdynamic -L/home/testuser/dev/niio/lib
-L/home/testuser/dev/niio/openmpi/lib
My question is, how to fix in my CMakeLists.txt to have main.cpp.o
first in
the sequence of the link command?
My current code is:
set(TARGET_NAME "niio-main")
link_directories("${PROJECT_SOURCE_DIR}/lib")
link_directories("${PROJECT_SOURCE_DIR}/openmpi/lib")
add_executable(${TARGET_NAME} main.cpp)
include_directories("${PROJECT_SOURCE_DIR}")
include_directories("${PROJECT_SOURCE_DIR}/openmpi/include")
add_definitions( -DOMPI_SKIP_MPICXX -DDEBUG -DNI_IO -DNI_MPI )
set_target_properties(${TARGET_NAME} PROPERTIES COMPILE_FLAGS "-fPIC -g
-Wall -Wno-deprecated")
set_target_properties(${TARGET_NAME} PROPERTIES LINK_FLAGS "-lfusion_io
-ladios -lmxml -lmpi -lopen-rte -lopen-pal -lpthread -lstdc++")
cmake --help-module FindMPI
cmake --help-module FindThreads (I doubt you need it, this is probably
only a dependency of MPI which should take care for that itself)
cmake --help-command link_directories
To get -g: cmake -D CMAKE_BUILD_TYPE=Debug … (or =RelWithDebInfo).
