I'm using CMake to build my application using Qt5, Boost and other libraries. It's been going great while I was developing on Ubuntu, now I'm trying to make my code build and run on OSX as well and have been running into some problems.
我正在使用CMake来使用Qt5、Boost和其他库来构建我的应用程序。在我开发Ubuntu的过程中，我一直在努力，现在我正在尝试让我的代码构建和运行在OSX上，并且已经遇到了一些问题。
The library file is there, something else is wrong.
库文件在那里，其他的东西是错误的。
Parts of my main CMakeLists.txt I think relevant:
我主要的CMakeLists部分。三种我认为相关:
project(lillebror)
cmake_minimum_required(VERSION 2.8)
cmake_policy(SET CMP0015 NEW)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost 1.54 COMPONENTS date_time log thread system unit_test_framework REQUIRED)
add_subdirectory(core)
add_subdirectory(server)
server/CMakeLists.txt
服务器/ CMakeLists.txt
aux_source_directory(. SRC_LIST)
add_executable(server ${SRC_LIST})
target_link_libraries(server core ${Boost_LIBRARIES})
However when I run it I get this error:
但是当我运行它时，我得到了这个错误:
make[2]: *** No rule to make target `/usr/local/lib/libboost_date_time-mt.a', needed by `server/server'. Stop.
I added a message(${Boost_Libraries}) in server/CMakeLists.txt and got this output:
我在服务器/CMakeLists中添加了一条消息(${Boost_Libraries})。txt得到这个输出:
/usr/local/lib/libboost_date_time-mt.a/usr/local/lib/libboost_log.a/usr/local/lib/libboost_thread-mt.a/usr/local/lib/libboost_system-mt.a/usr/local/lib/libboost_unit_test_framework-mt.a
The beginning of the cmake output looks like this:
cmake输出的开头是这样的:
-- Boost version: 1.54.0
-- Found the following Boost libraries:
-- date_time
-- log
-- thread
-- system
-- unit_test_framework

I grepped for "date" in build/server/... and found this:
我在build/server/…,发现:

So it seems to be included in the linking step as well. And there they're seperated.
所以它似乎也包含在连接步骤中。他们分离。

So it turned out that the file did not exist. It was a symlink to a file that didn't exist, something in my boost installation is wrong.
原来文件不存在。它是一个不存在的文件的符号链接，在我的boost安装中有些东西是错误的。
Lesson: don't just check for file existence, check for symlinks.
教训:不要只检查文件是否存在，检查符号链接。
