cmake在linux上复制fortran模块失败

Question

我有一个使用cmake构建的fortran代码版本。目前它正在Mac OS X上工作，但是当我尝试在Linux上构建它时，它失败了。 Cmake成功生成makefile，但是当我尝试运行makefile时，尝试复制模块时失败。

顶级cmake的文件是：

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) 

所有模块应该被复制到构建/模块。当我运行在Linux上使用详细的Makefile文件= 1，我得到：

/usr/bin/cmake -H/home/user/reconstruction -B/home/user/reconstruction --check-build-system CMakeFiles/Makefile.cmake 0

我使用gfortran作为我的编译器，而不是f95的时候有同样的问题。为什么在Mac OS X上工作但在Linux上失败？在Mac OS X上，我安装了2.8.8版本的cmake和Linux版本2.8。

Answer 1

原来有一个看似无关的错误导致了问题。我有一些语句来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'为空时，if语句总是显示为true。这在编译器命令行中导致了一个额外的-I，它将所有东西搞砸了。
