Static library linking failed for 16.04 on rpi3

Hi, my first post,
i have two make files, one building a static library, other is to build with lib linking
when i use make for 2nd file i am getting linker error

/usr/bin/ld: skipping incompatible ../development/lib/libstat_cpp.a when searching for -lgurux_dlms_cpp
/usr/bin/ld: cannot find -lstat_cpp
collect2: error: ld returned 1 exit status
makefile:27: recipe for target 'bin/client.bin' failed
make: *** [bin/client.bin] Error 1
anything i am missing?
make file1:

#---------------------------------------------------------------------------

Generate STATIC library.

TARGET = libstat_cpp.a
CC = g++

compiling flags here

#CFLAGS = -O3 -Wall -fPIC
CFLAGS = -O3 -Wall -fPIC

LINKER = ar rvs

linking flags here

LFLAGS =

change these to set the proper directories where each files shoould be

SRCDIR = src
OBJDIR = obj
LIBDIR = lib

SOURCES := $(wildcard $(SRCDIR)/.cpp)
INCLUDES := $(wildcard $(SRCDIR)/
.h)
OBJECTS := $(SOURCES:$(SRCDIR)/%.cpp=$(OBJDIR)/%.o)
rm = rm -f

$(LIBDIR)/$(TARGET): $(OBJECTS)
@$(LINKER) $@ $(LFLAGS) $(OBJECTS)
@echo "Linking complete!"

$(OBJECTS): $(OBJDIR)/%.o : $(SRCDIR)/%.cpp
@$(CC) $(CFLAGS) -c $< -o $@
@echo "Compiled "$<" successfully!"

.PHONEY: clean
clean:
@$(rm) $(OBJECTS)
@echo "Cleanup complete!"
@echo $(OBJECTS)

.PHONEY: remove
remove: clean
@$(rm) $(LIBDIR)/$(TARGET)
@echo "Executable removed!"

make file 2:

project name (generate executable with this name)

TARGET = client.bin

CC = g++

compiling flags here

CFLAGS = -c

LINKER = g++ -o

linking flags here

LFLAGS = -L../development/lib

change these to set the proper directories where each files shoould be

SRCDIR = src
OBJDIR = obj
BINDIR = bin

SOURCES := $(wildcard $(SRCDIR)/.cpp)
INCLUDES := $(wildcard $(SRCDIR)/
.h)

OBJECTS := $(SOURCES:$(SRCDIR)/%.cpp=$(OBJDIR)/%.o)
rm = rm -f

$(BINDIR)/$(TARGET): $(OBJECTS)
@$(LINKER) $@ $(LFLAGS) $(OBJECTS) -lstat_cpp
@echo "Linking complete!"

$(OBJECTS): $(OBJDIR)/%.o : $(SRCDIR)/%.cpp
@$(CC) $(CFLAGS) -c $< -o $@
@echo "Compiled "$<" successfully!"

.PHONEY: clean
clean:
@$(rm) $(OBJECTS)
@echo "Cleanup complete!"
@echo $(OBJECTS)

.PHONEY: remove
remove: clean
@$(rm) $(BINDIR)/$(TARGET)
@echo "Executable removed!"

solved by re building both make files, sorry
