boost lib命名丢失 [英] boost lib naming are missing
问题描述
我已经下载了boost并构建了它，这不是第一次，但是随后事情似乎变得很奇怪.
I've downloaded boost and built it, and not for the first time, but then things started to seem weird.
起初，我在编译项目(使用boost)时遇到了这些错误:
At first I got these errors while compiling my project (which uses boost):
/usr/local/include/boost/system/error_code.hpp:221: undefined reference to `boost::system::generic_category()'
/usr/local/include/boost/system/error_code.hpp:222: undefined reference to `boost::system::generic_category()'

/usr/local/include/boost/system/error_code.hpp:223: undefined reference to `boost::system::system_category()'
因此，我去检查是否所有内容都到位，并发现我没有的boost lib文件没有通常的库命名，即它们看起来像:libboost_thread.a，libboost_system.a，libboost_date_time.a ，而不是-mt，-d等.
So I went to check if everything is in place and found out that the boost lib files I have don't have the usual library naming, that is they just look like: libboost_thread.a, libboost_system.a, libboost_date_time.a, instead of the -mt, -d and so on.
我不记得我是如何构建的，但是如果我尝试运行的话:
boost_src_dir > ./b2 threading=multi link=static variant=debug,release
我得到:
I don't remember how exactly I built it, but if I try to run:
boost_src_dir > ./b2 threading=multi link=static variant=debug,release
I get:
error: Name clash for '<pstage/lib>libboost_atomic.a'
error:
error: Tried to build the target twice, with property sets having
error: these incompatible properties:
error:
error: - <debug-symbols>on <inlining>off <optimization>off <runtime-debugging>on <variant>debug
error: - <debug-symbols>off <define>NDEBUG <inlining>full <optimization>speed <runtime-debugging>off <variant>release
error:
error: Please make sure to have consistent requirements for these
error: properties everywhere in your project, especially for install
error: targets.
不太清楚发生了什么事，以前我做过这件事很顺利..
有什么想法吗?
Not quite sure what's going on, the previous times I've done this it went pretty smooth..
Any ideas?
我正在使用linux mint(17.2 x64)，提升1.59并与cmake一起使用，如下所示:
I'm using linux mint (17.2 x64), boost 1.59 and use it with cmake like so:
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package(Boost 1.36.0 COMPONENTS system thread shared_ptr)
if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})
else()
message("can not find boost")
endif()
谢谢.
推荐答案
关于报告的error: Name clash for '<pstage/lib>libboost_atomic.a':
我只是在这里总结说明和解决方案(@Nitzan Tomer提供了简短地)，为此，@ Samidamaru的答案没有提供解决方案.
I'm just summarizing here the explanation and solution (which @Nitzan Tomer gave briefly above, and for which, @Samidamaru 's answer did not provide a resolution).
问题与--layout规范有关.有关--layout选项，请参见b2 --help.
The problem was about --layout specification. See b2 --help for the --layout option.
在Linux上，默认布局为system，这意味着对于所有类型的构建，都使用以下模式创建库:libboost_<library-name>.a(在Windows上为.lib).
这意味着将为debug和release变体创建相同的文件.由于Nitzan通过传递variant=debug,release来请求这两种变体，因此创建的文件将相互覆盖. b2将此报告为错误.
On Linux the default layout is system, which means that for all kind of builds, the libraries are created with the schema: libboost_<library-name>.a (or .lib on Windows).
It means that the same file would be created both for debug and release variant. Since Nitzan requested both variants by passing variant=debug,release the created files would overwrite each other. b2 reported this as an error.
+-----------------------+-------------------------------------------------------------------------------+----------------------------------------+-------------------------+

| | versioned | tagged | system |

当然，在Linux上，使用.a和.so后缀，而在Windows上使用.lib和.dll. Windows上的DLL名称中省略了lib前缀.
在Windows上，仅在设置runtime-link=static选项时才能创建单线程版本.
Of course on Linux the .a and .so post-fixes are used vs. .lib and .dll on Windows. The lib prefix is omitted from DLL names on Windows.
On Windows the single-threaded versions can be created only if the runtime-link=static option was set.
对于标题，仍然在指示的文件夹下创建通常" boost目录. --prefix=/tools/boost到b2，然后为versioned布局创建以下目录结构:
For headers, the "usual" boost directory is still created under the indicated folder.
It means that if you passed e.g. --prefix=/tools/boost to b2, then the following directory structure is created for the versioned layout:
/tools/boost
|
+--- lib
|
+--- include
+--- boost_{boost version tag}
|
+--- boost
+--- accumulators
+--- algorithm
etc.
未为其他布局创建boost_{boost version tag}(例如boost_1_68)中间目录.
The boost_{boost version tag} (e.g. boost_1_68) intermediate directory is not created for other layouts.
