静态链接到libpthread

Question

我需要制作一个基本上静态的应用程序/库。此应用程序的依赖项之一是libpthread。要求我静态链接到libpthread。我正在使用CMake。

如果我要运行ldd myapp，应该不列出libpthread.so.0。

我尝试了多种方法以及每种方法的各种组合，所有这些都会导致动态链接：

find_package(Threads REQUIRED)
target_link_libraries(myapp
    PRIVATE
        Threads::Threads
)

This post：

target_link_libraries(myapp
    PRIVATE
        -lpthread -Wl,-u,pthread_join,-u,pthread_equal
)

This post：

target_link_libraries(myapp
    PRIVATE
        -Wl,--whole-archive -lpthread -Wl,--no-whole-archive
)

This post：

set(CMAKE_THREAD_PREFER_PTHREAD TRUE)
set(THREADS_PREFER_PTHREAD_FLAG TRUE)

set_target_properties(myapp PROPERTIES LINK_SEARCH_START_STATIC 1)
set_target_properties(myapp PROPERTIES LINK_SEARCH_END_STATIC 1)

set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++")

find_package(Threads REQUIRED)
target_link_libraries(myapp Threads::Threads)  

和

target_link_libraries(myapp
    PRIVATE
        -static -lpthread
)
