Issue
I'm new in C++ and CMake projects. I write (with CLion) very simple application that uses mysql connector.
This require to install on system libmysqlcppconn-dev. That is no problem on system where I build this but if I want to execute it on other system it fails because it needs shared library.
I want to include that library into my project.
For this in my project I created folder lib/static and I copied files.
$ tree lib/static
lib/static
├── libmysqlcppconn.a
└── libmysqlcppconn-static.a
these files after instaling dev library are located:
/usr/lib/x86_64-linux-gnu/libmysqlcppconn-static.a
/usr/lib/x86_64-linux-gnu/libmysqlcppconn.a
/usr/lib/x86_64-linux-gnu/libmysqlcppconn.so
now in my CMalke.lists I added:
#find_library(MYSQLCPP mysqlcppconn-static lib/static/)
add_library(MYSQLCPP STATIC IMPORTED)
set_property(TARGET MYSQLCPP PROPERTY IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/lib/static/libmysqlcppconn-static.a)
link_directories(lib/static)
target_link_libraries(${project_name} oatpp pthread curl ${MYSQLCPP})
but this won't compile
[100%] Linking CXX executable ../dist/bin/smsapiclient
/usr/bin/ld: CMakeFiles/smsapiclient.dir/src/App.cpp.o: in function `MyController::rootPOST(oatpp::data::mapping::type::String const&)':
/home/marcin/projects/smsapiclient/src/controller/MyController.hpp:61: undefined reference to `get_driver_instance'
collect2: error: ld returned 1 exit status
If I uncomment find_library() function and comment add_library() set_property() I'm getting that error
[ 98%] Linking CXX executable ../dist/bin/smsapiclient
/usr/bin/ld: /home/marcin/projects/smsapiclient/lib/static/libmysqlcppconn-static.a(mysql_client_api.cpp.o): in function `sql::mysql::NativeAPI::LibmysqlStaticProxy::options(MYSQL*, mysql_option, void const*)':
(.text+0x4c4): undefined reference to `mysql_options'
everything works with shared system library but I want to add it into executable to be non depediency on other systems.
How should I include static library into my project correctly? Thanks for you help in advance.
after build ii with system's libraries, ldd shows:
