Boost库在Windows上无法正确链接

我有一个大型项目，该项目最初是在Macos上构建的，我正尝试在Windows上进行编译。该项目的makefile如下：

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)

请注意，前一个是（工作中的）macos目标，后一个是Windows目标。尝试在Windows上链接boost时，我不断收到大量未定义的参考错误，例如：

那只是一个片段，我所能找到的所有信息都说这是一个促进链接的问题，但是我无法一辈子都将其固定下来。我正在使用以下命令编译boost 1.69.0：

.\boostrap.bat

./bjam

./bjam install

以与找到的说明here类似的方式。我已经尝试过jsut，我想了一切，并且花了很多时间重新编译boost，因此，您可能会提供的任何帮助将不胜感激！

我尝试过的事情：

  • 检查这些库是否确实存在于/ stage / lib中，它们是否与.a和.dll.a文件一样。
  • 将整个boost文件夹移到我的build文件夹的相对路径中，以防我错误地指定了link / include文件夹。
  • 使用大量选项重新编译boost，我几乎无法全部撤回它们。

我怀疑您可能有多个问题...

您的makefile指定boost库的不同版本：1.69.0和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

就这么简单。

但是，在Windows机器上，命令是：

.\boostrap.bat

通常假定使用boost构建Visual Studio库。 因此，根据构建boost库的位置，您可能构建了Visual Studio个lib文件，而不是g++个lib文件。您可以从库文件名中得知：

// gcc, actually mingw73: mgw73
libboost_filesystem-mgw73-mt-x64-1_69.dll.a

// msvc 2017: vc141
boost_filesystem-vc141-mt-x64-1_69.lib

听起来您的说法是正确的，但是您可以在构建g++时显式指定boost编译器，例如：

.\boostrap.bat gcc

最后，很难维护跨平台makefiles，尤其是对于boost。
我建议改为使用cmake。
