pnacl-ld cannot find library

All the time I get an error the library is not found, how to correctly specify the address of the library ?

C:\nacl_sdk\pepper_49\getting_started\SmartBox>make

 CXX  pnacl/Release/smart_box.o

 LINK pnacl/Release/smart_box_unstripped.bc

pnacl-ld: Cannot find '-lbox_api'

Makefile:31: recipe for target 'pnacl/Release/smart_box_unstripped.bc' failed

Do see the commands that make is running can you add VERBOSE=1 to your
make invocation?

Also, what is the contents of the $(NACL_SDK_ROOT)/lib/box_api
directory? For your approach to work it should contain the
libbox_api.a library, which it seems like it probably doesn't.

cheers,

I tried lib to convert to a, using https://code.google.com/archive/p/lib2a/

If you want to use the library you would need to compile it with the
NaCl toolchain.
