Question

我的目标是能够尽可能地提供单个可执行文件，因此我的目标是尽可能静态地瞄准。但我现在遇到了libc的一些问题。我在构建项目时遇到了这些错误：

/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libpthread.a(pthread_create.o): In function `allocate_stack':

搜索了一段时间后，我发现添加--static-libgcc and -static-libstdc++应该修复它，但似乎没有。

我正在Ubuntu上构建它。

这是我的主要CMakeLists.txt：

这是服务器/ CMakeLists.txt：

aux_source_directory(. SRC_LIST)
add_executable(server ${SRC_LIST})
target_link_libraries(server core ${Boost_LIBRARIES})

服务器的链接输出如下所示：

如果您有一般性的建议或改进，而不仅仅是解决这个问题的方法，我也对这些问题感兴趣。

我在静态链接方面遇到了类似的问题。我建议尝试几件事：

1）尝试逐步静态链接（从所有动态开始并一次添加一个静态库）。这样，您就可以完全调试破坏构建的库。

2）提供您正在使用的静态库的完整路径，即代替＆＃34; -Bstatic -lpthread＆＃34;你可以做＆＃34; / usr / lib /..../ libpthread.a＆＃34;。我正在使用它进行交叉编译，但它也应该对你的情况有帮助。

使用1和2，您可以找出哪个库破坏了您的构建并使用该库的动态版本。在你的情况下，它看起来像是libpthread，所以你可以尝试动态版本的libpthread，但错误消息有时是欺骗性的。如果这有帮助或者您遇到其他错误，请告诉我。
