Hi,
I have a project which in which I create a library and then I
use
this library with my executable. The way I set it up seem to be
working on
linux (fedora) but it does not work on mac ox10.
Could someone tell me what I am doing wrong,
Thanks,

Project tree
*Projectdir
**mdi
**skinmesh
in my project directory I have the following cmake file :
--------------
project(mdi C Fortran CXX)
cmake_minimum_required(VERSION 2.4.0)
# Set a variable to point to our top level project directory
SET (MDI_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR})
SET(PROJECT_BINARY_DIR
${CMAKE_SOURCE_DIR}/bin)
SET(LIBRARY_OUTPUT_PATH
${CMAKE_SOURCE_DIR}/lib)
# Add some include paths to the subdirectories
INCLUDE_DIRECTORIES ( ${MDI_SOURCE_DIR}/mdi
${MDI_SOURCE_DIR}/skinmesh )
# tell cmake to process CMakeLists.txt in these subdirectory
#they have to be added separately for it to work
#this subdirectory will create a lib so I put the lib in the lib folder
add_subdirectory(
skinmesh
${PROJECT_BINARY_DIR}
)
add_subdirectory( skinmesh ${PROJECT_BINARY_DIR}/skinmesh )
add_subdirectory( mdi ${PROJECT_BINARY_DIR}/mdi )
#this add the executable in the bin directory
add_subdirectory (
mdi
${PROJECT_BINARY_DIR}
)
--------------
In the mdi directory I have the following cmake file (part of it
anyay) :
--------------
[..]
SET(SKINMESH_LIBRARIES
${LIBRARY_OUTPUT_PATH}/libskinmesh.a
)
This is NOT needed because CMake will "know" about the library
libSkinMesh.a
SET(SKINMESH_INCLUDE_DIR
${CMAKE_SOURCE_DIR}/skinmesh
)
This was taken care of in the top level CMakeLists.txt file and is NOT
needed
SET(INCLUDE_DIR
${INCLUDE_DIR}
${SKINMESH_INCLUDE_DIR}
)
NOT NEEDED...
SET(LIBRARIES
${LIBRARIES}
${SKINMESH_LIBRARIES})
NOT needed. Use the name of the library directly in the
TARGET_LINK_LIBRARIES function:
SET (SKINMESH_LIB_NAME "skinmesh" )
[..]
# Mac configuration
IF ( CMAKE_SYSTEM_NAME MATCHES "Darwin" )
#setting flags
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O3 -mp1 -Kc++ -Dintel")
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -O3 -mp1 -Kc++ -Dintel")
#equivalent to ldflag
SET( CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}
-bind_at_load")
ENDIF ( CMAKE_SYSTEM_NAME MATCHES "Darwin" )
#VARIABLE INITIALISATION
# set source files
[..]
SET(mdi_EXECUTABLE
${mdi_SRCS}
${mdi_UIS_H}
${mdi_MOC_SRCS}
${mdi_RCC_SRCS}
)
This....
INCLUDE_DIRECTORIES(${INCLUDE_DIR})
link_directories (${PROJECT_BINARY_DIR}/skinmesh)
CMAKE will KNOW where to look for the library. Not needed.
# create an executable file named "mdi" from the source files in the
variable "mdi_SRCS".
ADD_EXECUTABLE ( mdi ${mdi_EXECUTABLE} )
TARGET_LINK_LIBRARIES ( mdi
${LIBRARIES}
)
TARGET_LINK_LIBRARIES (mdi ${SKINMESH_LIB_NAME})
-------------
In the skinmesh directory I have the following cmake file (part of it
anyay) :
-------------
# create an executable file named "skinmesh" from the source files in
the
variable "skinmesh_SRCS".
ADD_LIBRARY ( skinmesh STATIC
${skinmesh_SRCS}
)
#set the linker language
SET_TARGET_PROPERTIES(skinmesh
PROPERTIES
LINKER_LANGUAGE CXX
)
[..]
# Mac configuration
IF ( CMAKE_SYSTEM_NAME MATCHES "Darwin" )
#setting flags
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -c -O3 -mp1 -Kc++ -Dintel")
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -c -O3 -mp1 -Kc++
-Dintel")
SET(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -c -u -O3
-mp1 -w90 -w95
-cpp ")
#equivalent to ldflag
SET( CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -O3
-Kc++ -mp1
-bind_at_load")
ENDIF ( CMAKE_SYSTEM_NAME MATCHES "Darwin" )
This...
INCLUDE_DIRECTORIES (${INCLUDE_DIR})
Most likely not needed because we set the include directories in the
top level CMakeLists.txt file
TARGET_LINK_LIBRARIES (skinmesh
${PROJECT_LIBRARIES}
)
I will assume that PROJECT_LIBRARIES was set somewhere above and has
all your 3rd party libraries that you need listed.
hope some of this helps.
