Cannot build

[bradenbest]

There is no build system and there is no makefile in src/. Attempting to manually compile the files in src/ and platforms/qt-shared reveals many issues.

video.cpp miscapitalizes video.h as Video.h, resulting in the compiler being unable to find it. I had to make a symlink to help it along.

After getting the files to compile into objects, I am unable to link them, as there seems to be no file in the directory containing a main(). Where is the entry point?

So I try going to platforms/qt-shared and compiling those.

platforms/qt-shared $ g++ -c about.cpp
In file included from about.cpp:20:0:
about.h:23:22: fatal error: ui_About.h: No such file or directory
compilation terminated.

platforms/qt-shared $ g++ -c main.cpp
main.cpp:20:24: fatal error: QApplication: No such file or directory
compilation terminated.

All of the files have some fatal error that prevents them from compiling. There are several files and even entire directories that are inexplicably missing from the project.

Yes, because I don't even started coding it :smile:

[bradenbest]

Naive approach: I tried going gung-ho style and writing my own main.cpp:

#include "geardrive_core.h"

int main(void){
    GeardriveCore gdc;
    gdc.LoadROM("./sonic.bin");
}

And then...

$ ./a.out
1: Loading ./sonic.bin...
Segmentation fault

@drhelius You can't close an issue that isn't resolved. Your project clearly has issues and even bugs, as can be seen where it invokes undefined behavior and crashes, evidently from trying to read 8 bytes from a null pointer.

The fact that you closed this legitimate issue saying that you haven't "started coding it", and that the last update was made 4 years ago, tells me that this project is abandoned.

If this isn't abandoned, you need to reopen this issue. If it is, you need to be honest and say that in the README.

[drhelius]

Sorry but it's not going to work, the only finished part is the z80 core, I started coding the 68k core but then paused and focused on NES emulation. I'll try to return to Genesis / MD any time soon.

@drhelius If you really mean that, you should re-open this issue, and only close it when you at least have a makefile or some basic build system that results in a functional program.
