Cmake 编译设置

问题描述

利用编写的CmakeLists文件编译链接fortran编写函数库与C++编写的geant4程序；需要解决的问题有：

1.如何设置环境变量；

2.如何利用CmakeLists编译fortran代码；

3.如何在C++中调用fortran编写的函数；

代码实现

1.环境变量设置

export PATH=$PATH::$PWD/bin #设置执行文件安装路径export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$(pwd)/lib #设置库文件路径

2.如何利用CmakeLists编译fortran代码；

#----------------------------------------------------------------------------# Setup the projectcmake_minimum_required(VERSION 2.6 FATAL_ERROR)set(PROJ_NAME FortranEarthAtmosphere)project($PROJ_NAME)enable_language(Fortran)set(CMAKE_BUILD_TYPE Release)#----------------------------------------------------------------------------# Locate sources and headers for this project# NB: headers are included so they will show up in IDEs#file(GLOB_RECURSE sources  ${PROJECT_SOURCE_DIR}/*.f*)add_library(${PROJ_NAME} SHARED ${sources})install(TARGETS ${PROJ_NAME} DESTINATION lib)

3.如何在C++中调用fortran编写的函数；
