Hi
How I can use stemwin library?
Any body can help me?
I just want use the static library (.a). How I can use in yotta?
Have you tried to create your own module, and there in source folder, create CMakeLists.txt file to add that static library, using add_library (add_library — CMake 3.0.2 Documentation).
An example of custom CMakeLists.txt file from k64f hal :mbed-hal-k64f/CMakeLists.txt at master · ARMmbed/mbed-hal-k64f · GitHub, just for illustration.

Hi
Thank you for response
I create new module with “mbed-stemwin” name. and create file in source
add_library(mbed-stemwin STATIC IMPORTED)
set_property(TARGET mbed-stemwin PROPERTY IMPORTED_LOCATION "./STemWin526_CM4_GCC.a")
set_target_properties(mbed-stemwin PROPERTIES
LINKER_LANGUAGE C
)
but when run yt build create error

Thank you I fixed this.
Can you share with us how did you fixed it?
add_library(mbed-stemwin_s STATIC IMPORTED)
set_property(TARGET mbed-stemwin_s PROPERTY IMPORTED_LOCATION "STemWin522_CM4_GCC.a")
add_library(mbed-stemwin mbed-stemwin.c)
target_link_libraries(mbed-stemwin mbed-stemwin_s)
could you share the libary with me? Or provide more details?
There’s a guide here to creating a yotta module for an existing binary library.
Note that doing this does severely limit the portability of your module though, so if possible import the source of the library into a yotta module which can be recompiled for different platforms 
Thanks, I’ll have a look
