Linker file cannot find my libraries

Posted by guillaumeibanez on 2016-01-04 17:04

Hi gharibi,

I have the same problem: I added “${ProjDirPath}/Middlewares/ST/STemWin/Lib/STemWin528_CM4_GCC.a” in Libraries (Properties -> Paths and Symbols)
I also tried to rename with lib in suffix and prefix and with or without “.a” but always this message : “....ne-eabi/4.9.3/../../../../arm-none-eabi/bin/ld.exe: cannot find -lD:/Users/Guillaume/STM32Projects/test2.0/testa/Middlewares/ST/STemWin/Lib/STemWin528_CM4_GCC.a ”

Why there is a ” -l ” before “D:/Users/Guillaume/STM32Projects/test2.0/testa/Middlewares/ST/STemWin/Lib/STemWin528_CM4_GCC.a “? I think it could be the issue but I tried to change the way in the objects.mk file but because of it’s a derivated file, I can’t do anything.

Thank you,
Guillaume

Here, the problem is due to the fact that, for GCC, libraries should have a name starting by “lib” and finish by “.a”; here STemWin528_CM4_GCC.a can’t be included simply

The simplest way to include it needs

  1. To manually rename STemWin528_CM4_GCC.a to, for example, libSTemWin.a
  2. To add two settings, both located in project >> Properties >> C/C++ Build >> Settings >> MCU GCC Linker >> Libraries:
    • in the Libraries (-l) pane, add STemWin
    • in the Library search path pane add ${ProjDirPath}/Middlewares/ST/STemWin/Lib


Then the linker should find the STemWin library

Hope this helps,

Bernard (Ac6)
