Building dynamic libraries
Building dynamic libraries
To build a dynamic library, you need to use the following CMake command:
add_library(<build target name> SHARED <path to a file of the library source code>…)
You can also build a dynamic library by using the following CMake command:
add_library(<build target name> <path to a file of the library source code>…)
The cmake shell command must be called with the -D BUILD_SHARED_LIBS=YES parameter. (If the cmake shell command is called without the -D BUILD_SHARED_LIBS=YES parameter, a static library will be built.)
Example:
#!/bin/bash
…
cmake -G "Unix Makefiles" \
-D CMAKE_BUILD_TYPE:STRING=Debug \
-D CMAKE_TOOLCHAIN_FILE=$SDK_PREFIX/toolchain/share/toolchain-$TARGET.cmake \
-D BUILD_SHARED_LIBS=YES \
-B build \
&& cmake --build build --target kos-image
By default, the library file name matches the name of the build target defined via the parameter of the CMake add_library() command. The library file name can be changed by using the CMake set_target_properties() command. This can be done to make the library file name identical for its dynamic and static variants.
Example:
# Build the static library
add_library(somelib_static STATIC src/somesrc.cpp)
set_target_properties(somelib_static PROPERTIES OUTPUT_NAME "somelib")
# Build the dynamic library
add_library(somelib_shared SHARED src/somesrc.cpp)
set_target_properties(somelib_shared PROPERTIES OUTPUT_NAME "somelib")
A dynamic library can be linked to other static and dynamic libraries by using the CMake target_link_libraries() command. In this case, static libraries must be built with the -fPIC flag. This flag is applied when building a static library if the following CMake command is used:
set_property(TARGET <build target name>… PROPERTY POSITION_INDEPENDENT_CODE ON)
