我有一个使用 cmake 构建的 fortran 代码构建。这目前在 Mac OS X 上运行，但是当我尝试在 Linux 上构建它时，它失败了。Cmake 成功生成了makefile，但是当我尝试运行makefile 时，它​​在尝试复制模块时失败了。

顶级 cmake 文件是：

cmake_minimum_required (VERSION 2.8)

# Start Project and note the language used.
project (v3fit_suite Fortran)

# Set a directories to build all binary files.
set (EXECUTABLE_OUTPUT_PATH ${CMAKE_CURRENT_SOURCE_DIR}/build/bin)
set (LIBRARY_OUTPUT_PATH ${CMAKE_CURRENT_SOURCE_DIR}/build/lib)

# Fortran specific settings. The first setting tells the compiler to use the C preprocessor. The second places a common directory to place all of the module files.
set (CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -cpp")
set (CMAKE_Fortran_MODULE_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/build/modules)

# List all the subdirectories these are in library dependancy order.
add_subdirectory (LIBSTELL)
add_subdirectory (VMEC2000)
add_subdirectory (V3FITA)
add_subdirectory (MAKEGRID)
add_subdirectory (V3POST)
add_subdirectory (V3RFUN)

所有模块都应复制到 build/modules。当我在 Linux 上使用 VERBOSE=1 运行 Makefile 时，我得到：

使用 gfortran 而不是 f95 作为编译器时，我遇到了同样的问题。为什么这在 Mac OS X 上工作但在 Linux 上失败？在 Mac OS XI 上安装了 2.8.8 版的 cmake，在 Linux 上安装了 2.8 版。

原来有一个看似无关的错误导致了这个问题。我有一些语句要添加一个空的包含路径。

find_library (NETCDF_F netcdff PATHS ${NETCDF_LIB_PATH})
find_file (NETCDF_I netcdf.inc ${NETCDF_INC_PATH})
if (NETCDF_C AND NETCDF_F AND NETCDF_I)
    message (STATUS "Using netcdf")
    set (CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -D NETCDF -I ${NETCDF_INC_PATH}")
endif ()

即使 'NETCDF_INC_PATH' 为空，if 语句也始终为真。这导致编译器命令行中出现了一个额外的 -I ，这把一切都搞砸了。
