使用cygwin时如何静态link libssl和libcrypto？

Question

cmake_minimum_required(VERSION 3.17)
project(test)

set(CMAKE_CXX_STANDARD 17)

add_executable(test main.cpp)

target_link_libraries(test ssl crypto)

使用上面的CMakeLists.txt时，可以link动态的openssl lib

但是当添加 -static

cmake_minimum_required(VERSION 3.17)
project(test)

set(CMAKE_CXX_STANDARD 17)

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -static")
add_executable(test main.cpp)

target_link_libraries(test ssl crypto)

发生错误

/usr/lib/gcc/x86_64-pc-cygwin/7.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lssl
/usr/lib/gcc/x86_64-pc-cygwin/7.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lcrypto

如何在使用 cygwin 时静态 link libssl 和 libcrypto？

Answer 1

见
https://cygwin.com/packages/x86_64/libssl-devel/libssl-devel-1.1.1n-1

包只提供共享导入库

usr/lib/libcrypto.dll.a
usr/lib/libssl.dll.a

所以你不能静态地link他们
