试图安装一个Spenvis软件包，这是运行脚本时遇到的错误：
-- Boost version: 1.41.0 -- Found the following Boost libraries: -- python -- Configuring done -- Generating done -- Build files have been written to: Desktop/build make[2]: *** No rule to make target `/usr/local/lib64/libpython2.6.so.1.0', needed by `source/libSpenvis.so'. Stop. make[1]: *** [source/CMakeFiles/Spenvis.dir/all] Error 2 make: *** [all] Error 2 它在/ usr / local / lib64中查找libpython2.6.so.1.0，但是库本身位于/ usr / lib64中。
我不是一个超级用户，所以我不能改变/将库复制到目录中，也不能将其链接到该目录。 作为参考，下面是我正在运行的python脚本，后面跟着CMakeLists.txt文件：
""" Main launch script """ import os import sys import shutil from subprocess import call """ Define path where to find python packages """ loc_dir=os.getcwd() os.chdir("python_utilities") #Spenvis csv ############# os.chdir("spenvis_csv") if not os.path.exists("build"): os.mkdir("build") os.chdir("build") call("cmake ../", shell=True) call("make") os.chdir(loc_dir) os.chdir("python_utilities") if not os.path.exists("lib"): os.mkdir("lib") for file_name in os.listdir("spenvis_csv/build/source"): if file_name.find("libSpenvis.") !=-1: shutil.move("spenvis_csv/build/source/%s" %(file_name),"lib/Spenvis.so") os.chdir("..")
和CMakeLists.txt：
cmake_minimum_required(VERSION 2.8) # Make sure the compiler can find include files include_directories (${PYSPENVIS_SOURCE_DIR}) # get boost set(Boost_USE_STATIC_LIBS OFF) #set(Boost_USE_MULTIEADED ON) find_package(Boost COMPONENTS python REQUIRED) include_directories(${Boost_INCLUDE_DIRS}) link_directories(${Boost_LIBRARY_DIRS}) # get python include(FindPythonLibs) set(PythonLibs_USE_STATIC_LIBS OFF) find_package(PythonInterp) find_package(PythonLibs) include_directories(${PYTHON_INCLUDE_DIRS}) link_directories(${PYTHON_LIBRARIES}) add_library(Spenvis SHARED pySpenvisCSV.cc SpenvisCSV.cc SpenvisCSVCollection.cc) TARGET_LINK_LIBRARIES(Spenvis ${Boost_LIBRARIES} ${PYTHON_LIBRARIES})
接受build议，我使用CMakeLists.txt文件在目录中运行以下命令：
cmake -DPYTHON_LIBRARY='/usr/lib64/libpython2.6.so.1.0'
这产生了：
Boost found. Found Boost components: python -- Found PythonLibs: /usr/lib64/libpython2.6.so.1.0 (found version "2.7.1") -- Found PythonLibs: /usr/lib64/libpython2.6.so.1.0 (found suitable version "2.7.1", minimum required is "2.6") -- Configuring done -- Generating done -- Build files have been written to: blahblahblah
回去运行install.py程序现在返回：
-- Boost version: 1.41.0 -- Found the following Boost libraries: -- python -- Found PythonLibs: /usr/local/lib64/libpython2.6.so.1.0 (found version "2.6.6") -- Found PythonLibs: /usr/local/lib64/libpython2.6.so.1.0 (found suitable version "2.6.6", minimum required is "2.6") -- Configuring done -- Generating done -- Build files have been written to: /home/smh/Linux/Desktop/gras original/gras-03-03/python/python_utilities/spenvis_csv/build make[2]: *** No rule to make target `/usr/local/lib64/libpython2.6.so.1.0', needed by `source/libSpenvis.so'. Stop.
所以，返回相同的错误，只是现在它声称它正在查找python库。 奇怪的是，它发现的python库不存在，也就是说，/ usr / local / lib64中没有libpython2.6.so.1.0，而是位于/ usr / lib64中。
在CMakeCache.txt中，关于所需库的行如下：
//No help, variable specified on the command line. PYTHON_LIBRARIES:UNINITIALIZED=/usr/lib64/libpython2.6.so.1.0 //Path to a library. PYTHON_LIBRARY:FILEPATH=/usr/lib64/libpython2.6.so //Dependencies for the target Spenvis_LIB_DEPENDS:STATIC=optimized;boost_python-mt-shared;debug;boost_python-mt-shared-debug;general;/usr/lib64/libpython2.6.so; //Details about finding PythonLibs FIND_PACKAGE_MESSAGE_DETAILS_PythonLibs:INTERNAL=[/usr/lib64/libpython2.6.so][/usr/local/include/python2.7][v2.7.1(2.6)]
/usr需要插入CMAKE_PREFIX_PATH前面，所以先找到它。
list(INSERT 0 CMAKE_PREFIX_PATH /usr)
