Issue while compiling the project on Windows

[alpyildirim97]

Hi,

I encountered with a compilation error when I am trying to compile the code on my windows machine. I use Mingw64 to use make and other POSIX compatibilities. The issue appeared on Options.hpp which indicates 'getopt' was not declared in this scope. I am sharing the detailed error message below:

g++ -std=c++11 -Wno-deprecated -O2 -DWIN32 -I./include -o bin/vf3 main.cpp -DVF3 main.cpp: In function 'int32_t main(int32_t, char**)': main.cpp:125:34: error: 'opt' was not declared in this scope 125 | std::ifstream graphInPat(opt.pattern); | ^~~ main.cpp:129:48: error: 'CreateLoader' was not declared in this scope; did you mean 'CreateJobSet'? 129 | ARGLoader<data_t, Empty>* pattloader = CreateLoader<data_t, Empty>(opt, graphInPat); | ^~~~~~~~~~~~ | CreateJobSet main.cpp:129:67: error: expected primary-expression before ',' token 129 | ARGLoader<data_t, Empty>* pattloader = CreateLoader<data_t, Empty>(opt, graphInPat); | ^ main.cpp:131:67: error: expected primary-expression before ',' token 131 | ARGLoader<data_t, Empty>* targloader = CreateLoader<data_t, Empty>(opt, graphInTarg); | ^ main.cpp:146:40: error: 'CreateMatchingEngine' was not declared in this scope 146 | MatchingEngine<state_t >* me = CreateMatchingEngine(opt); | ^~~~~~~~~~~~~~~~~~~~ make: *** [Makefile:10: vf3] Error 1
After some research I noticed that in Options.hpp file, #include <unistd.h> was defined in #ifdef WIN32 block which prevents to include getopt on windows. I updated that part as follows and the project compiled:

#ifdef WIN32 #include <getopt.h> #else #include <unistd.h> #endif
Please take a look if this is a real issue or somehow somethings wrong with my build. Hope it helps, thanks!
