Anyone with OBD Key software?

I will add that, independent of the shadyness of their operation, the fact that their software is based on a GNU general public license application gives you the right to freely redistribute their modification of it. I.E., what I'm requesting is legal.

I know that Dana Peters sold his application to other companies (not sure about OBDKey). IANAL, but I think it can be done without breaching the terms of the GPL. For example, look at FreeRTOS vs OpenRTOS.

Lemme see the error about cc.exe in detail, perhaps I can advise. Just the other day someone else got my software working under cygwin.

You can, indeed, sell the software for money.

But...

The GPL means you also must offer people [to whom you distribute your work] your modifications under the same license as you received permission to redistribute the original work - the GPL. So all it would take it one person to buy your stuff, and they can redistribute it after they get it from you.

The GPL absolutely doesn't preclude people making money from GPL software. It just precludes you from stopping people from redistributing your modifications to someone else's GPL'd code. Read Stallman's book ["Free as in Freedom"] for a cetechismic covering of this topic.

Gary, I copy/pasted my error below. Not really sure what is going on as I am not too familiar with cmake. Any ideas? I'm running 32-bit Win7 RC1.

$ cd obdgpslogger-0.9

$ cd build

$ cmake ..

Perhaps you need to install a C++ compiler aswell? There are some C++ components in obdgpslogger.

Try checking that you have the package gcc-g++ installed as well as gcc-core?

**chunkyks** · 10-17-2009, 01:15 PM

Oh, also, 0.9 is relatively old - I strongly suggest using an svn checkout of the code :-)

If all the code comes from a single author, that code can be licensed under multiple licenses (ex: GPL and Commercial). If, however, anyone contributes to that open source code, they now own part of the copyright. Their code is now released under GPL and cannot be licensed under any more restrictive license.

so i installed the g++ compiler and I got a little further into the build. i also checkedout your latest code from the svn and ran into a compilation error on line 303 of main.c. zErrMsg is not defined. after adding (char* zErrMsg

into the code, I got it to build up to this point (not sure what is wrong now!):

Oh, ugh. More posix-cygwin junk. First thing is that all that scary C++ vtable warning stuff is just cygwin trying to put the fear in you. Ignore it.

FWIW, obdgpslogger actually build for you; The actual error there is in obdsim. The short version is "just delete src/sim/CMakeLists.txt". That way it won't try to build obdsim at all.

Obviously I'd rather fix it properly, so ... please could you try adding this near the top of src/sim/simport.c :

Code:

#ifdef __CYGWIN__
    // Cygwin doesn't currently have posix_openpt(3).
    int posix_openpt(int oflag) {
        return open("/dev/ptmx", oflag);
    }
#endif

And yeah - I added that sqlite thing earlier but I guess I screwed up. Sorry! But that's the right fix :-)

**chunkyks** · 10-18-2009, 10:40 PM

... or edit simport.c, and uncomment the first line of simport_open, and comment the second line instead.

This is also my interpretation of the GPL.
