[CMake] CMakeSetup broken, fails in the root directory

[William A. Hoffman]

So, the logs don't help much other than to show most of the
stuff is working well.

The trouble is coming from here:
i:\tmp\CMake\Utilities\cmxmlrpc\CMake\TryCompileFromSource.cmake


   SET(src "${src}\nint main() { ${SOURCE} ; return 0; }")
    FILE(WRITE "${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/src2.c"
      "${src}\n")
    EXEC_PROGRAM("${CMAKE_COMMAND}" 
      "${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp"
      ARGS -E copy src2.c src.c)
    MESSAGE(STATUS "Performing Test ${VAR}")
    TRY_COMPILE(${VAR}
      ${CMAKE_BINARY_DIR}
      ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/src.c
      CMAKE_FLAGS
      "${TRY_COMPILE_FROM_SOURCE_ADD_LIBRARIES}"
      OUTPUT_VARIABLE OUTPUT)


Which is called from here:
Utilities/cmxmlrpc/CMakeLists.txt

INCLUDE (TryCompileFromSource)
SET(HEADER_INCLUDES "${CURRENT_INCLUDES}")
TRY_COMPILE_FROM_SOURCE("va_list list1, list2; list1 = list2"
  VA_LIST_ISNOT_ARRAY_DEFINE)
SET(VA_LIST_IS_ARRAY_DEFINE 0)
IF(NOT VA_LIST_ISNOT_ARRAY_DEFINE)
  SET(VA_LIST_IS_ARRAY_DEFINE 1)
ENDIF(NOT VA_LIST_ISNOT_ARRAY_DEFINE)


Could you try this:

In i:\tmp\CMake\Utilities\cmxmlrpc\CMake\TryCompileFromSource.cmake,
add some message statements.


message("src2.c = [${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/src2.c]")
message("src.c = [${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/src.c]")
message("CMAKE_COMMAND = ${CMAKE_COMMAND}")


For some reason the copy is not happening or something like that....

It does seem to be the only call of that macro in cmake.

You could also try replacing it with:

CHECK_C_SOURCE_COMPILES("va_list list1, list2; list1 = list2"
  VA_LIST_ISNOT_ARRAY_DEFINE)

in i:\tmp\CMake\Utilities\cmxmlrpc\CMakeLists.txt.
