[Cmake] Re: [vtkusers] Error while building VTK 4.2.1 with CMake on Linux

[Joseph Barraud]

You are perfectly right. This error message is in the CMakeError.log. In 
fact, ccmake just says "segmentation fault" and that's all.
Here is my CheckLibraryExists.cmake :

#
# Check if the function exists.
#
# CHECK_LIBRARY_EXISTS - macro which checks if the function exists
# FUNCTION - the name of the function
# VARIABLE - variable to store the result
#

MACRO(CHECK_LIBRARY_EXISTS LIBRARY FUNCTION LOCATION VARIABLE)
   IF("${VARIABLE}" MATCHES "^${VARIABLE}$")
     SET(MACRO_CHECK_LIBRARY_EXISTS_DEFINITION
         "-DCHECK_FUNCTION_EXISTS=${FUNCTION} ${CMAKE_REQUIRED_FLAGS}")
     MESSAGE(STATUS "Looking for ${FUNCTION} in ${LIBRARY}")
     SET(CHECK_LIBRARY_EXISTS_LIBRARIES ${LIBRARY})
     IF(CMAKE_REQUIRED_LIBRARIES)
       SET(CHECK_LIBRARY_EXISTS_LIBRARIES
           ${CHECK_LIBRARY_EXISTS_LIBRARIES} ${CMAKE_REQUIRED_LIBRARIES})
     ENDIF(CMAKE_REQUIRED_LIBRARIES)
     TRY_COMPILE(${VARIABLE}
                ${CMAKE_BINARY_DIR}
                ${CMAKE_ROOT}/Modules/CheckFunctionExists.c
                CMAKE_FLAGS
                  -DCOMPILE_DEFINITIONS:STRING=${MACRO_CHECK_LIBRARY_EXISTS_DEFINITION}
                  -DLINK_DIRECTORIES:STRING=${LOCATION}
                  "-DLINK_LIBRARIES:STRING=${CHECK_LIBRARY_EXISTS_LIBRARIES}"
                OUTPUT_VARIABLE OUTPUT)

     IF(${VARIABLE})
       MESSAGE(STATUS "Looking for ${FUNCTION} in ${LIBRARY} - found")
       SET(${VARIABLE} 1 CACHE INTERNAL "Have library ${LIBRARY}")
     ELSE(${VARIABLE})
       MESSAGE(STATUS "Looking for ${FUNCTION} in ${LIBRARY} - not found")
       SET(${VARIABLE} "" CACHE INTERNAL "Have library ${LIBRARY}")
       WRITE_FILE(${CMAKE_BINARY_DIR}/CMakeError.log
         "Determining if the function ${FUNCTION} exists in the ${LIBRARY} "
         "failed with the following output:\n"
         "${OUTPUT}\n" APPEND)
     ENDIF(${VARIABLE})
   ENDIF("${VARIABLE}" MATCHES "^${VARIABLE}$")
ENDMACRO(CHECK_LIBRARY_EXISTS)
