我正在尝试将MSVC中的问题与我为g ++编写的项目联系起来.这是问题所在:
我将libssh构建为静态库作为我的应用程序的一部分,在cmake中添加目标
add_library(ssh_static STATIC $ libssh_SRCS)
Libssh在C中,所以我有'extern'C"{...}'将包含在我的c ++源代码中.然后我将ssh_static目标链接到我的可执行文件sshconnectiontest
target_link_libraries(sshconnectiontest ... ssh_static ...)
这一切都适用于linux和gcc,但现在在MSVC中我得到了
error LNK2019: unresolved external symbol __imp__[function names here] referenced in [filename]
对于我使用的每个libssh函数.
任何想法都出错了？我已经读过某个地方,imp前缀意味着链接器期望链接.dll,但这不应该是这种情况,因为ssh_static在add_library调用中被声明为静态库...
我使用bjam构建了我的boost库,然后将所有.a文件移入c:\Server\libs\boost_1_46_0\lib
如果我想编译我的程序有一些错误:
编译命令

任何人都可以帮我解决这个问题的问题吗？
我遵循了这个教程: http ://antonym.org/2009/05/threading-with-boost---part-i-creating-threads.html
所以这是来源:http://pastebin.com/YqCPLNwU
更新:
我认为错误不在于库,错误在库中.我用bjam和toolchain=gcc multithread选项构建它.
UPDATE
这是objdump …
我正在尝试构建 Boost.Log ( http://boost-log.sourceforge.net/libs/log/doc/html/index.html )。我将其添加到我的 boost 源中并执行了我常用的 boost 构建命令。
b2 --build-dir="D:\boost\1.51.0\boost" toolset=gcc variant=release link=static threading=multi runtime-link=static --build-type=complete
但什么也没发生，我最终收到了这个：
