Doesn't compile with Cygwin:

Uncommenting line 36 and commenting line 37 of \src\sim\simport.c makes the error go away.

Edit: Added screen shot of codes from my Lumina. I know for sure the codes are P0300 and P1406, I guess you can sort of see one of them?

Yeah, I'm aware of that. I need to check for the posix_openpt symbol. The insulting bit is that posix_openpt is available in the header, and the other necessaries [eg posix_grantpt] are just fine. It's just that the symbol isn't publicly available in the cygwin C library itself.

You found the fix I'm going to use; the code will look like

Code:

---

#ifdef HAVE_POSIX_OPENPT
int fd = posix_openpt(O_RDWR);
#else
int fd = open("/dev/ptmx", O_RDWR);
#endif //HAVE_POSIX_OPENPT

---

Just gotta set up the build system to do it.

Heh, that's the svn that I only committed last night. Among other things, it doesn't gracefully handle multiple ECUs...

You're getting NO DATA; that's what happens when the OBD device literally responds with the string "NO DATA". Please could you run obdgpslogger with "-l seriallog.txt" [dash little-ell] and post the seriallog?

Thanks,

Zipped it up in case the browser decides to get creative with a .txt file that has binary contents. I did svn sync and rebuilt just now, then ran it.

OK, two things:
1) Please could you do an svn update [and probably an "svn revert src/sim/*", to back out your modifications], and see if it compiles on cygwin for you now? I'm explicitly checking for posix_openpt in the build system, and using open("/dev/ptmx") if that's not available.
2) Also, do an svn update; I *was* sending "0300" [ie mode+cmd], which is incorrect; mode 0x03 does not need a cmd. Perhaps that will fix the problem? If not [for that matter, even if it does], please could you upload a fresh seriallog?

Hope all that helps,

Reverted src/sim/* and everything compiles in Cygwin now. Did svn update but it's still getting NO DATA. Edit: Whoops ran obdgpslogger.exe instead of ./obdgpslogger.exe ... new seriallog now. Edit #2: Hah! Bluetooth port shut down before I ran the command and I didn't notice. Re-ran again and now it's printing out the codes:

That makes no sense at all.

Thus, I suggest you check that the OBD dongle is plugged in properly and hasn't wiggled loose.

I'm really pleased that it builds on cygwin now, though. Of course, I'd also like to know if it actually *works*, but building is a good start :-)

Gary (-;

Indeed! See above post, I edited it twice :)

Getting there! Sorry this is so difficult, I really appreciate your patience on the topic :-)

Also, could you upload another seriallog, [for -p, with the error output]? Those errors aren't the same as the ones you said you know they should be... Which may be an artifact of some other changes I made earlier this evening. Lots of development has gone on tonight, and I'm started to get tired.

Thanks,
