Hello!

Here is my CMakeLists.txt:

cmake_minimum_required(VERSION 3.3)
project(untitled19)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=3Dc++11")

set(LIBRARY_SRC library.cpp)

add_library(libra SHARED ${LIBRARY_SRC})

set(SOURCE_FILES main.cpp)
add_executable(untitled19 ${SOURCE_FILES})
target_link_libraries(untitled19 libra)

This works and both library a=
nd executable are compiled. Unfortunately library seems to be linked into t=
he executable: =E2=80=98nm=E2=80=99 command shows that the executable itsel=
f exports needed functions!

I do not think your interpreting the nm output correctly, but its hard t= o say without seeing it ;)

Note that nm will show = the functions exported by the library in the output for the executable, bec= ause the executable uses those functions. It will also indicate however tha= t these functions are not defined inside the executable in the correspondin= g column with an upper-case U. When you run nm on the library itself you wi= ll notice that the same symbols have a different type in the corresponding = column. In addition you can verify that the executable actually links again= st the library using the otool commandline tool: otool -L executable.
