C++ Link Failure - ld: cannot find [makefile] [gcc/cygwin] - c++

I am trying to create a system of makefiles to build my whole project. I am using cygwin and gcc compiler. I am running into a linking error on shared libraries that I cannot figure out.
I am concerned with ld: cannot find -lbase and ld: cannot find -lsimsimA429.
These files were clearly built. I even did a directory listing as part of the build command to show that they exist.
-rwxr-xr-x+ 1 user group 116832 Mar 25 10:09 /cygdrive/d/myProj/lib/libbase.so
-rwxr-xr-x+ 1 user group 75972 Mar 25 10:09 /cygdrive/d/myProj/lib/libsimsima429.so
and the link command also shows that I am including the correct link directory
g++ -shared -L/cygdrive/d/myProj/lib -lpthread -lrt -lbase -lsimsimA429 ...
What am I doing wrong to incur this error?
Also, I am relatively new to writing makefiles. If you have any comments about how I could improve them, I would kindly appreciate a few comments.
Full makefiles and output are listed below...

Cygwin shared libraries are *.dll files, not lib*.so files. I suppose your linker is struggling to find base.dll and simsimA429.dll.

MakeFile C++ problem only have .Object files

As the title say i have a problem compiling so i have my makefile who compile great my .cpp , then I have .o in the bin directory but after that its off I stay with my .o files and nothing change ,
It seems it doesnt take into account the few lines i wrote after and cant have my .exe
I think its something to do with the last lines because all the compile thing from .cpp to .o works great

include DLIB and other header files in C++ project

I'm trying to get dlib library working in my C++ project from last 2 weeks and found some solution but still i'm facing errors which i can not understand. As i am newbie to the makefile and dlib guide me what to do with makefile.
The folder structure is like this:
projectDir
|-makefile
|-src
|-CDetector.cpp
|-CDetectot.h
|-CStreamReader.cpp
|-CStreamReader.h
|-include
|-darknet
|-(files).h (other .h files needed by src files)
|-dlib-19.6
|-all
|-source.cpp
|-lots of header files
|-...
|-external_libs
|-libdarknet.a
|-libdarknet.so
The makefile looks like this:
EXE = darknet
OBJ_DIR = obj
CXXFILES = $(shell find src -type f -name '*.cpp')
CXXOBJ = $(patsubst src/%.cpp,obj/%.o,$(CXXFILES))
INCLUDE = -I/include -I/include/darknet
LIBS = external_libs/libdarknet.a
CXXFLAGS = `pkg-config --cflags-only-I opencv` -Wall -Wno-unknown-pragmas -Wfatal-errors -Wwrite-strings -fPIC
LDFLAGS = -lm -pthread -lX11 -DDLIB_JPEG_SUPPORT -ljpeg
all: $(EXE)
$(EXE): $(CXXOBJ)
$(CXX) $(CXXOBJ) -o $(EXE) $(LIBS) $(LDFLAGS)
$(OBJ_DIR)/%.o: src/%.cpp
$(CXX) $(CXXFLAGS) $(INCLUDE) $< -c -o $#
$(BUILD)
run: all
./$(EXE)
clean:
-rm -f $(EXE) $(CXXOBJ)
rmdir obj/
It needs some modification as INCLUDE, CXXFLAGS AND LDFLAGS will be
INCLUDE = -Iinclude -Iinclude/darknet `pkg-config --cflags-only-I opencv`
CXXFLAGS = -Wall -Wno-unknown-pragmas -Wfatal-errors -Wwrite-strings -fPIC
LDFLAGS = -lm -pthread -lX11 -DDLIB_JPEG_SUPPORT -ljpeg -lopencv_videoio `pkg-config --libs opencv`
and i'm now using darknet makefile to do it so my makefile looks like
VPATH = ./src/
ALIB = external_libs/libdarknet.a
EXEC = darknet
OBJDIR = ./obj/
CC = g++ -std=c++11
NVCC = nvcc
AR = ar
ARFLAGS = rcs
OPTS = -Ofast

I'm in Ubuntu 16.04.3 LTS xenial and I'm trying to run the command make on the terminal, but I'm getting this error:

Makefile:81: recipe for target 'DRS.o' failed

I think that I must do this correction:
This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
I have never tried to do something like this before, so I don't know how to correct.

In my research I didn't find anything helpful.
Sorry for the long post, couldn't make it more simple.
You simply need to set the C++ standard by adding it to the CFLAGS, ie:
CFLAGS += -std=c++11
I have the same problem you have and I was looking for an answer but can't find one so I solved it on my own. In my case, the problem is with the string.h header file I removed it and my code is working now.

Separate compiling a .cu file, .c file and main.cpp file and linking together using a makefile

This is how my makefile looks like, I have seperata cudaex.cu cudaaex.h plotter.c plotter.h and mainfn.cpp files. I compiled and created .o files separately. But I cant link them and make an executable file. If further informations needed I can post other codes also.
CUDA ?= /usr/local/cuda
CUDA_LIB :=-L $(CUDA)/lib64 -L $(CUDA)/lib -L /usr/lib64/nvidia -L /usr/lib/nvidia
CUDA_INC += -I $(CUDA)/include
program_INCLUDE_DIRS := ./src
program_LIBRARY_DIRS :=

LDFLAGS += $(CUDA_LIB) -L $(CUDA)/lib64
LIBS += -lcudart -lcuda -lpthread -ldl

this is the output of the make command

Makefile with different compiler flags for source files

How do I use different compiler flags for different source files in a Makefile? For example, I'd like a Makefile that will produce:
g++ -c -COMPILER_FLAGS_1 -g source1.cpp -o source1.o
g++ -c -COMPILER_FLAGS_2 -g source2.cpp -o source2.o
g++ -c -COMPILER_FLAGS_2 -g source3.cpp -o source3.o
g++ -c -COMPILER_FLAGS_2 -g source4.cpp -o source4.o
g++ -c -COMPILER_FLAGS_3 -g source5.cpp -o source5.o
g++ -c -COMPILER_FLAGS_3 -g source6.cpp -o source6.o
g++ -c -COMPILER_FLAGS_3 -g source7.cpp -o source7.o
g++ -g -o output source1.o source2.o source3.o source4.o source5.o source6.o source7.o
At the moment I've got about 20 source files (and that's expected to grow), so an easy to maintain file would be nice.
Thanks in advance.
You could do something like the following (untested, so the syntax might be slightly off):
OBJS_1 := source1.o
OBJS_2 := source2.o source3.o source4.o
OBJS_3 := source5.o source6.o source7.o
OBJS := $(OBJS_1) $(OBJS_2) $(OBJS_3)
output: $(OBJS)
$(CXX) -g -o $# $^
$(OBJS_1): CXXFLAGS := $(COMPILER_FLAGS_1)
$(OBJS_2): CXXFLAGS := $(COMPILER_FLAGS_2)
$(OBJS_3): CXXFLAGS := $(COMPILER_FLAGS_3)
$(OBJS): %.o: %.cpp
$(CXX) -c $(CXXFLAGS) -g $< -o $#
Here is UNIX/LINUX makefile which I wrote and tested on Solaris LINUX to handle different compilation flags for different sections of a GNUmakefile. Please let me know if it can be improved. Thank you
