  Hello everyone

  I am trying to generate a dynamic library with integration of NIM and PostgreSQL, it works very well in Ubuntu, but in macOS it generates the following error

  
  ld: warning: ignoring file Makefile, building for macOS-x86_64 but attempting to link with file built for unknown-unsupported file format ( 0x50 0x47 0x5F 0x53 0x45 0x52 0x56 0x45 0x52 0x5F 0x49 0x4E 0x43 0x3D 0x20 0x24 )
  Run

  Este es el make file con el que trato de generar la bibilioteca dinamica

  
  # Objetos de C
  MY_OBJS=addone.o magic.o utilities.o concat.o
  
  all: $(MY_LIB_NIM) $(MY_OBJS) $(MY_LIB_GCC)
          @echo Compilacion en Nim culminada con exito!!!
  
  $(MY_LIB_NIM): *.nim Makefile
          nim c -d:release --gc:arc -d:useMalloc --passC:-fPIC --noMain --opt:speed --app:staticlib --outdir:$(NIM_OUTDIR) --nimcache:$(NIM_CACHEDIR) --out:$(basename $<).a --header:$(basename $<).h $<
  
  %.o: %.c Makefile
          gcc -std=c11 -fPIC -O2 -D_GNU_SOURCE -c $< -I$(PG_SERVER_INC) -I$(NIM_INCLUDE_BASE) -I$(NIM_INCLUDE_LOCAL)
  
  $(MY_LIB_GCC): $(MY_OBJS) Makefile
          gcc -shared -fPIC -O2 $^ $(MY_LIB_NIM) -o $@
  Run

  Any solution for this error?

  Thank you!

  This looks like a mistake in your Makefile — I think you need to remove Makefile from the right-hand side of your rules, because it’s feeding the Makefile itself to the build commands. I think the error comes from the linker trying to treat the Makefile as a library.
