I am using the Project/Build Settings dialog to try to add an additional library to my project.  Using the "Additional Libraries" and the "Additional Libraries Directories" tabs does add the items to the linker command but since the directories is added after the library is added it appears as though the library can't be found.  The linker command becomes:

   

-mcpu=cortex-m0 -mthumb -g -ffunction-sections -O0 -l m -l ..\..\..\Documents\MotionDriver\Arm_Source\libmplmpu -L Generated_Source\PSoC4 -L ..\..\..\Documents\MotionDriver\MPL_Libraries -Wl,-Map,${OutputDir}/${ProjectShortName}.map -T Generated_Source\PSoC4\cm0gcc.ld -specs=nano.specs -Wl,--gc-sections

   

​But seemingly:  -l ..\..\..\Documents\MotionDriver\Arm_Source\libmplmpu

   

isn't found because the directory to look in: -L Generated_Source\PSoC4 -L ..\..\..\Documents\MotionDriver\MPL_Libraries

   

hasn't been added to the path yet.  That's speculation on my part and I'd welcome any feedback on how to accomplish this.  The error that is thrown looks like:

Ray,

   

Would you please post a simple example (including the libraries) so I can attempt to reproduce the behavior?

I'm wondering if I could get around this by placing my library file in the same directory as the libm.a file that is linked properly (I assume due to some default path).  Any idea where that is on a PSOC installation?

Scott,  Thanks for the reply.  I believe I have resolved this.  I needed to add the include path also.  In my defense I would have thought the -l and -L commands should have sufficed 🙂

@ray.parker_1412866 can you please explain, how you made it work? 
I'm facing a similar problem.

Welcome in the forum!

   

Afaik libraries have to be named yourlibrarilib.a in the dialog you only need to enter "yourlibrary"

   

as an example: to include mlib.a (the math library) you enter just "m".

Welcome in the forum.

   

Oh yes, can it be that the "lib" is preceded and not trailing.

Hi, I'm facing the same problem. How do I solve this? I have tried removing the .a and lib extensions to no avail
