DBSaga Compiling Issues

Hello everyone OLaD here. I'm new to coding and found this old DBSaga codebase. I've spent a week on this forum and other boards trying to get this to compile on my widows 10 x64 with cygwin.

I know this has been addressed many times and is an old topic. I hope you all are still around to help a newbie like me!

This is the newest result of running 'make' in cygwin.

NOTE; per instructions with the read me with the code, the folder dbs is moved into the c:\cygwin64\home\ohloo\ dir

The first thing is to get the "make" working and by the look of it you possibly don't have an "o" directory (for the object files) underneath the "src" directory.
Ohlookadime #4
There is one already. In the dbs/src dir
Nick Gammon Australia Forum Administrator #5
Try running make in debug mode. Possibly:


make --dry-run



You should see echoed what make is trying to do, what files it is sending to gcc (or g++) so you can confirm if the source files exists, and the destination directories exist.
Ohlookadime #6
This is what I got. I'm a complete n00b still but I didn't see anything bad.

Does gcc34 exist? Try typing:


gcc34 --version

I've reinstalled more gcc packages for cygwin, apparently I don't have the right ones yet lol. Thank y'all for the continued help!


[EDIT]
I have removed the '34' from gcc34 in the make file, that has solved the gcc issue. Now this is showing when I run make again.

It looks like the same error, over and over for each file. Why you get that message I can't say, as I can't see the source code you are using.

I could upload the archive I have as a zip or is there another way to show you? I'd really like to get this to work.

Thank you.
Nick Gammon Australia Forum Administrator #14
Perhaps post the link to where it is?

An occupational hazard of compiling old source code is that compilers have become more strict. They try to stop you doing things like buffer overflow, which people exploit to hack into systems.

Thus, code that compiled 10 or 20 years ago doesn't compile now. So, you need to understand what the code does in order to fix the issues. Sometimes this is not at all simple.

You found it on ufile.io?

OK, what is happening here is that the author defined variables in the mud.h file, for example:


...

bool	MOBtrigger;

...

NOTE_DATA *note_free;

...

int	top_mob_serial;


And so on. You can't do that, because each compilation unit (the .c files) then adds that declaration into the object file, and then the linker (not the compiler) finds multiple instances of them.

What you need to do is find all those variables in mud.h (the variable names will be in the error message, as shown above) and then change them to extern <the variable> for example:


...

extern bool	MOBtrigger;

...

extern NOTE_DATA *note_free;

...

extern int	top_mob_serial;


That tells the compiler to not set memory aside for them because they will be declared elsewhere (externally).

Then you have to declare them once, so you choose a file (eg. comm.c) and put them all inside there, ie. (after all the #include lines):



bool	MOBtrigger;
NOTE_DATA *note_free;
int	top_mob_serial;
...


So that declares the one (and only) copy of those variables. Now all the other files will be redirected to the single instance of them.

I can't say that will get rid of all the errors, but it should help.

Thank you very much, I will try this tomorrow.

Also, I have another version from a friend that's been trying to get this codebase to work also. Not getting any duplicate errors instead I receive this;

You only have one error there (the rest are warnings):


act_move.c:653:22: error: lvalue required as left operand of assignment


You may want to search what that means.

As an example, this simple program gives the same error message:


int main ()
  {
  unsigned char c;
  (char) c = 'a';
  }


However this does not:


int main ()
  {
  unsigned char c;
  c = (unsigned char) 'a';
  }


In other words, you cast the source of an assignment (the rvalue), not the destination (the lvalue).
