Problems adding a new library .a

Posted by GregoNv on 2018-02-01 12:12

Hi,

I am having some problem adding a new library to a project. I opened Properties/C/C++ General/Path and Symbols/Library Path and i added the .a file. When i did it, in C/C++ Build/Setting/MCU GCC LInker, it appears on the added libraries list. which i think is how it should be. But when I build the project, I get the following error:

c:/ac6/systemworkbench/plugins/fr.ac6.mcu.externaltools.arm-none.win32_1.11.0.201610101338/tools/gcc-arm-none-eabi-5_4-2016q2-20160622-win32/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -lC:/Users/Gregorio/Desktop/NewMCUfiles/SSD1963(23012018)1/SSD1963/SSD1963/EmWin/libSTemWin522_CM4_GCC.a

So apparently it can’t find the library and I don’t know why.

Thank you for your help

Hi,

To load a library, the best way is to

Set a -L option with the directory where the library is:
- project properties >> C/C++ Build >> Build settings >> MCU GCC Linker >> Libraries >> Libraries search path
- in your case this is /Users/Gregorio/Desktop/NewMCUfiles/SSD1963(23012018)1/SSD1963/SSD1963/EmWin
Set a -l option with the library base name:
- project properties >> C/C++ Build >> Build settings >> MCU GCC Linker >> Libraries >> Libraries
- in your case this is STemWin522_CM4_GCC

The linker will search for libyour_lib_name.a in the library search path provided and should find your library

Sir

I’ve just created a new project and I’m having a lot of issues with it. When I tried to build it, a message appeared saying that ‘building is finished’.But lot of errors in console window. I figured out that binaries is missing under my file name in the project explorer. Please see the attachment showing the error message. Please reply.

I am using STM32 AC6 software system workbench & STM32F3 DISCOVERY Board. Please do the needful

Please reply then only i can start my research work. I am a new learner of this software.

Hi,

It looks like you can’t run the compiler program (arm-none-gnueabi-gcc.exe). No project can compile on your system.
I’m not sure if it is due to an other software or if your installation directory path is not supported.

Do you have unix-like environment installed in your system (such as cygwin or msys) ? Do you run System Workbench from this environment ?
Can you verify that your installation path does not contains special character or space ? (maybe there is a bug on this)

Regards,
Kevin

I’ve had the same problem. When I tried to compare to a project that would both compile and link with the same library - I noticed that in the project that would link in the library the library name was prefixed with : so in the properties the correct library name was :-S

TemWin_CM7_GCC_ARGB.a instead of STemWin_CM7_GCC_ARGB.a ! Notice also, that I kept the .a suffix - otherwise the linker can not find the library!
