cmake link 错误 - 顺序依赖或其他？
cmake link error - order dependency or something else?
我正在尝试在 Ubuntu 14.04 上构建 Sigil。它编译但不会 link.
我读过 this (the error there looks very much like what I'm seeing) and this。我确信我找到了罪魁祸首，但是当我查看构建文件时，Python 库已经排在 link 顺序的最后：
kevin@aphrodite:~/src/Sigil$ grep -r 'target_link_libraries' .
./src/CMakeLists.txt~:target_link_libraries( ${PROJECT_NAME} ${QT_MAIN} ${HUNSPELL_LIBRARIES} ${PCRE_LIBRARIES} gumbo ${MINIZIP_LIBRARIES} ${BOOST_LIBS} ${XERCES_LIBRARIES} ${XERCESEXTENSIONS_LIBRARIES} ${PYTHON_LIBRARIES} )
./src/CMakeLists.txt:target_link_libraries( ${PROJECT_NAME} ${QT_MAIN} ${HUNSPELL_LIBRARIES} ${PCRE_LIBRARIES} gumbo ${MINIZIP_LIBRARIES} ${BOOST_LIBS} ${XERCES_LIBRARIES} ${XERCESEXTENSIONS_LIBRARIES} ${PYTHON_LIBRARIES} )
./3rdparty/minizip/CMakeLists.txt:target_link_libraries( ${PROJECT_NAME} ${ZLIB_LIBRARIES} )
./cmake_extras/FindPythonLibs.cmake:# target_link_libraries(${_NAME} ${PYTHON_LIBRARIES})
我对cmake不是很熟悉，所以被难住了。我唯一能想到的另一件事是我安装了两个不同版本的 Python（2.7 和 3.4），因为一堆核心 Ubuntu 软件包需要 2.x 而 Sigil 需要 3.x.如果这是问题所在，我不知道该怎么办。
这是成功的构建命令：
cmake -G "Unix Makefiles" -DCMAKE_PREFIX_PATH=/home/kevin/local/qt/5.4/gcc_64/lib/cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_LIBRARY=/usr/bin/python3.4 -DFORCE_BUNDLED_COPIES=1 /home/kevin/src/Sigil
这里是 link 命令，它失败了。这里有确凿证据吗？

作为起点，尝试手动输入以下命令行
[OMITTED, SEE EDIT HISTORY IF INTERESTED]
基本上我只是把Python3.4换成了Python2.7；请仔细检查 /usr/bin
中的库名称
我现在看到你有一个解决方案，根本问题是在 CMakeLists.txt 这一行
find_package (PythonLibs 3.4)
应该是：
find_package (PythonLibs 3.4 REQUIRED)
Antonio 建议给 message(STATUS "PYTHON_LIBRARIES = ${PYTHON_LIBRARIES}") 打电话，这让我找到了 /facepalm。
在我的 cmake 命令中，我输入了 -DPYTHON_LIBRARY=/usr/bin/python3.4。那是一个可执行文件，而不是一个库。我不确定导致我把它放在那里的事件的确切顺序，但我认为它是这样的：
- 尝试仅安装 Python 2.7 进行构建；
cmake 失败，因为找不到合适的 Python 版本。
- 已安装 Python 3.4。如果此时我再次尝试构建，可能会失败，因为
cmake 并没有真正的 "clean" 选项，所以它可能卡在了 Python 2.7.
- 输入那个伪造的库路径。
然后 cmake 成功了，显然对它实际上并没有用于任何用途的虚假路径感到满意，只是写入了 Makefile。
在使用干净的项目树重新开始后，我看到了我以前从未见过的这一行：
Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.4m.so (found suitable version "3.4", minimum required is "3.4")
现在 make 有效！
我正在尝试在 Ubuntu 14.04 上构建 Sigil。它编译但不会 link.
我读过 this (the error there looks very much like what I'm seeing) and this。我确信我找到了罪魁祸首，但是当我查看构建文件时，Python 库已经排在 link 顺序的最后：
kevin@aphrodite:~/src/Sigil$ grep -r 'target_link_libraries' .
./src/CMakeLists.txt~:target_link_libraries( ${PROJECT_NAME} ${QT_MAIN} ${HUNSPELL_LIBRARIES} ${PCRE_LIBRARIES} gumbo ${MINIZIP_LIBRARIES} ${BOOST_LIBS} ${XERCES_LIBRARIES} ${XERCESEXTENSIONS_LIBRARIES} ${PYTHON_LIBRARIES} )
./src/CMakeLists.txt:target_link_libraries( ${PROJECT_NAME} ${QT_MAIN} ${HUNSPELL_LIBRARIES} ${PCRE_LIBRARIES} gumbo ${MINIZIP_LIBRARIES} ${BOOST_LIBS} ${XERCES_LIBRARIES} ${XERCESEXTENSIONS_LIBRARIES} ${PYTHON_LIBRARIES} )
./3rdparty/minizip/CMakeLists.txt:target_link_libraries( ${PROJECT_NAME} ${ZLIB_LIBRARIES} )
./cmake_extras/FindPythonLibs.cmake:# target_link_libraries(${_NAME} ${PYTHON_LIBRARIES})
我对cmake不是很熟悉，所以被难住了。我唯一能想到的另一件事是我安装了两个不同版本的 Python（2.7 和 3.4），因为一堆核心 Ubuntu 软件包需要 2.x 而 Sigil 需要 3.x.如果这是问题所在，我不知道该怎么办。
这是成功的构建命令：
cmake -G "Unix Makefiles" -DCMAKE_PREFIX_PATH=/home/kevin/local/qt/5.4/gcc_64/lib/cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_LIBRARY=/usr/bin/python3.4 -DFORCE_BUNDLED_COPIES=1 /home/kevin/src/Sigil
这里是 link 命令，它失败了。这里有确凿证据吗？

作为起点，尝试手动输入以下命令行
[OMITTED, SEE EDIT HISTORY IF INTERESTED]
基本上我只是把Python3.4换成了Python2.7；请仔细检查 /usr/bin
中的库名称我现在看到你有一个解决方案，根本问题是在 CMakeLists.txt 这一行
find_package (PythonLibs 3.4)
应该是：
find_package (PythonLibs 3.4 REQUIRED)
Antonio 建议给 message(STATUS "PYTHON_LIBRARIES = ${PYTHON_LIBRARIES}") 打电话，这让我找到了 /facepalm。
在我的 cmake 命令中，我输入了 -DPYTHON_LIBRARY=/usr/bin/python3.4。那是一个可执行文件，而不是一个库。我不确定导致我把它放在那里的事件的确切顺序，但我认为它是这样的：
- 尝试仅安装 Python 2.7 进行构建；
cmake失败，因为找不到合适的 Python 版本。 - 已安装 Python 3.4。如果此时我再次尝试构建，可能会失败，因为
cmake并没有真正的 "clean" 选项，所以它可能卡在了 Python 2.7. - 输入那个伪造的库路径。
然后 cmake 成功了，显然对它实际上并没有用于任何用途的虚假路径感到满意，只是写入了 Makefile。
在使用干净的项目树重新开始后，我看到了我以前从未见过的这一行：
Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.4m.so (found suitable version "3.4", minimum required is "3.4")
现在 make 有效！
