Boost Libraries not linking properly on Windows - c++

Question

I've a large project which was originally built on Macos, that I'm trying to get compiling on Windows. The makefile for the project is as follows:
CC=C:/cygwin64/bin/g++.exe
BASE_FLAGS = -std=c++14
LDFLAGS = -I/usr/local/Cellar/boost/1.69.0/include -I/opt/local/include -I include/
LLIBFLAGS = -L/usr/local/Cellar/boost/1.68.0/lib
LINKFLAGS = -lboost_thread -lboost_system -l boost_filesystem -l boost_regex -ll -lm
FLAGS = $(BASE_FLAGS) $(LLIBFLAGS) $(LDFLAGS) $(LINKFLAGS)
rwildcard=$(wildcard $1$2) $(foreach d,$(wildcard $1*),$(call rwildcard,$d/,$2))
SRCS := $(call rwildcard,src/,*.cpp) $(call rwildcard,src/,*.c)
mac:
cd src; bison -d parse.y --debug -t; flex lex.l
time ./runscripts.sh
$(CC) $(FLAGS) -o main.out $(SRCS)
BASE_FLAGS_WIN = -std=gnu++11
LDFLAGS_WIN = -I include/ -I C:\Users\elllz\Downloads\boost_1_69_0
LLIBFLAGS_WIN = -LC:\Users\elllz\Downloads\boost_1_69_0\stage\lib
LINKFLAGS_WIN = -lm -lboost_system -lboost_regex -lboost_filesystem -lboost_thread
FLAGS_WIN = $(BASE_FLAGS_WIN) $(LDFLAGS_WIN) $(LLIBFLAGS_WIN) $(LINKFLAGS_WIN)
win:
bison -d .\src\parse.y -t -g
flex .\src\lex.l
.\scripts\ALL_HEADER_TOKENS.bat
cp .\parse.tab.h .\src\parse.tab.h
cp .\parse.tab.c .\src\parse.tab.c
cp .\lex.yy.c .\src\lex.yy.c
rm .\parse.tab.h .\parse.tab.c .\lex.yy.c
$(CC) $(FLAGS_WIN) $(SRCS)
Note that the first second is the (working) macos target, and the later is the Windows target. When trying to link boost on Windows, I keep getting a plethora of undefined reference errors, like such:

That's only a snippet, all the information I can find says it's a boost linking problem, but I can't pin it down for the life of me. I'm compiling boost 1.69.0 with the commands:
.\boostrap.bat
./bjam
./bjam install
In a similar manner to the instructions found here. I've tried jsut about everything I can think of, as well as spent a lot of time recompiling boost, so any help you might be able to offer would be greatly appreciated!
Things I have tried:
Checking the libaries do exist in /stage/lib, they do, as .a and .dll.a files.
Moving the entire boost folder into a relative path of my build folder, in case I was specifying the link / include folders wrong.
Recompiling boost with a host of options, I can't come close to recalling them all.

Answer 1

I suspect that you may have multiple issues...
Your makefile specifies different versions of the boost libraries: 1.69.0 and 1.68.0
LDFLAGS = -I/usr/local/Cellar/boost/1.69.0/include -I/opt/local/include -I include/
LLIBFLAGS = -L/usr/local/Cellar/boost/1.68.0/lib
It could be as simple as that.
However, on a Windows machine, the command:
.\boostrap.bat
normally assumes building the boost libraries using Visual Studio.
So depending upon where you built the boost libraries from, you may have built Visual Studio lib files, not g++ lib files. You can tell from the library file names:
// gcc, actually mingw73: mgw73
libboost_filesystem-mgw73-mt-x64-1_69.dll.a
// msvc 2017: vc141
boost_filesystem-vc141-mt-x64-1_69.lib
It sounds like yours are correct, but you can specify the g++ compiler explicitly when building boost, e.g.:
.\boostrap.bat gcc
Finally, it's difficult to maintain cross platform makefiles, especially with boost.
I recommend using cmake instead.
