Unable to run mftraning - Segmentation fault (core dumped)

[vzani]

Hello

I just compiled tesseract 3.04 on CentOS and it works perfectly.

But I´m trying to run mftraining and I´m getting this error:

[~/tesseract-master]# mftraining
Segmentation fault (core dumped)

Any suggestions?

Thanks

I can not reproduce it on openSUSE 13.2. Try to provide more details.

[jbreiden]

./configure --enable-debug
Then provide a backtrace with gdb (if you know how)

[vzani]

I have never done that, but anyway I gave a try but got stucked:

@vzani: when you start gdb, please enter command:
run

[vzani]

Thanks, @zdenop

The result is:

@vzani: the critical part is entering the command "backtrace" after the segmentation fault.

[cammette]

entered the command "backtrace",the result is:

Any suggestions?

Thanks

Can you double check the compilation environment?
the reserve function being in ccutil/genericvector.h on line 484 looks like version 3.02.02
Is older version of tesseract already installed?

[zdenop]

If you still have a problem please try current stable release (3.04.01).
Please uninstall all old tesseract installations before installing new tesseract version.

@koralatov, did you add this junk message, or was your account hacked? After looking at the activity list, I reported abuse to GitHub.

[ghost]

Sorry. At some point overnight someone/thing hacked my email and sent these and quite a number of other obviously spammy emails. I'm cleaning up now.
