Doublefann not working on windows
Hi, I'm using XAMPP 3.1.0 (PHP5.4.7) on Windows8
Running the sample_training gives me the following crash:
There is no information in the error.log.
I've tried the 1.0.3/1.0.4/1.0.5 versions for 5.4-ts-vc9-x86.zip and they all crash.
Any solution?
I'm not sure about XAMPP 3.1.0, is there such version? On their site http://www.apachefriends.org/de/xampp-windows.html the highest is 1.8.x. Nevertheless, do you have the same crash running that code on CLI? It would be great if you could
- extract a short PHP snippet reproducing this crash
- use this page https://bugs.php.net/bugs-generating-backtrace-win32.php to produce a backtrace
Please try on CLI with the official PHP build first (if you aren't using it already).
Yes, it crashes on cli too.
if (($this->ann = fann_create_from_file($path)) == false) {
throw new \Exception('Could not create ANN from file!');
}
PS. using xampp 1.8.1
Thanks, having the snippet is great. However I'd really appreciate to see the backtrace you have, preferably using the binary from http://windows.php.net/downloads/releases/ .
Thanks
Hi, I just tested the snippet with the uploaded file on Linux and it loads the network correctly without any crash. It looks that it is a platform specific though. If you could provide the backtrace, that would be great!
Thanks
I tried but I don't know how to configure the Debug Diagnostics Tool v2.0 (different than 1.2 tutorial). I think I'll first install the latest xampp version, then try again. Then I'll figure this debugging out if it still fails.
Installed xampp 1.8.3 (php5.5.3) but the error still occurs.
Or xmpp backtrace at least. You can run httpd.exe -X and attach debugger.
I don't know how to do this exactly... Is there an easy way to do the debugging? I'm using symfony2.
Is this correct?

From what i see now - please exclude xdebug and try again. An example of good usable backtrace is on that page btw https://bugs.php.net/bugs-generating-backtrace-win32.php , just in the first section. The debug symbols should be used. No symfony please, just the repro snippet from above. WinDbg shouldn't differ very much.
Another thing - the XMPP page states you need VC9 for its packages. If they have 5.5 bins compiled with VC9, that will sure conflict with the FANN builds wich are done with VC11 for PHP 5.5. What is the exact constellation they deliver in that package, which compiler is used for Apache and PHP?
@bukka I've just debugged this case. Please look here https://gist.github.com/weltling/7273037 for the diff. What happens is, that fann_create_from_file() delivers NULL. fann_get_errno() will try to dereference it.
The gist fixes that the latter, you might want to modify it for more meaningful reaction. Where I have no idea is why NULL is delivered. That's anyway an existing file and the the libfann refuses it for some reason. Maybe incorrect file format?
I managed to re-create the bug when I tested completely invalid conf file (the uploaded file is correct on linux so I tested completely invalid input: https://github.com/bukka/php-fann/blob/master/tests/fann_create_from_file_basic.phpt#L17
I added the extra checks for empty ann ( https://github.com/bukka/php-fann/commit/4400a4cb8b8686ed55434439ddf39de10adf728f ) but then I got another segfault. It looks that there is some problem in libfann as they are some memory corruptions. Valgrind also showed me quite a few additional problems (memory leaks) for error cases. I will need to do a proper testing and try to sort it out in ext code (in the worst case I will have to rewrite config file parser)...
@weltling Thanks a lot for debugging the code! I have got one question regarding your diff? Did it actually work? As I wrote there is still segfault on my Linux build so I am a bit curios if it works on another build...
@Tjorriemorrie Thanks for reporting the problem. I will release a new version when I fix it... ;)
@bukka, i've actually worked on the snippet and data brought earlier by @Tjorriemorrie. For that the diff i've posted was sufficient. Maybe the data isn't completely invalid, so quite an edge case. Nevertheless libfann delivered NULL.
Please just ping when you think it's ready, i'll trigger a snap from master then.
Cheers
