Seg fault on Mac OS 10.6.2

[Tax Man]

Hi, cuneiform builds nicely on Mac OS, but on running it with the basic command line
cuneiform -o 0001.txt 0001.jpg
for an image with English text fails with only the error Segmentation fault.
I could try attaching an image, but it does the same thing with various image formats, tiff, jpg, and the included test bmp's.
I built with a debug build type, but I still don't get any more information. Let me know if there is anything I can do to provide more information.

Also a small separate note. On Debian and Debian derived Linux distributions, the needed ImageMagick libraries are in a separate package from ImageMagick. It would be good to note in the readme that libmagick++-dev needs to be installed as well.

Oh, I get the same behavior after building the same version - 0.8.0 - on Ubuntu. Just shoot me if it's user error.

[Tax Man (taxman457f)]

Jason said: "I would suggest rebuilding it with debugging symbols and running it in gdb to get a backtrace for the developers."
So I did that on my Ubuntu and Mac systems and attached the results, they are both in the file. Sorry I'm not really familiar with GDB and coding, but I can supply any information that someone gives me some hints on how to obtain.

It gives no debug information available errors for the Mac build even though I built both of them with the
cmake -DCMAKE_BUILD_TYPE=debug ..
config option.

This is correct, sorry I've just noticed that I replied to Jason directly instead of posting to the bug. The backtrace does not look particularly helpfull, maybe you can do a full backtrace (I guess it's bf or something like this) and also run it through strace...

[Tax Man (taxman457f)]

Sure. I've attached the full gdb backtrace along with some extra stuff suggested here: https://wiki.ubuntu.com/Backtrace in case it's helpful. I'll also attach the strace output, but it seems I can't attach two files at once, so I'll do that in a second.

[Tax Man (taxman457f)]

Now I've had a chance to grab the full backtrace on the Mac. Let me know if you want to see the dtrace output on the Mac, and if so, what options.

[Yury V. Zaytsev (zyv)]

Wow, that looks funny. Thanks! Hopefully Jussi can look into this.

Snow Leopard by default builds 64 bit binaries. Can you try building 32-bit version and seeing if it crashes too? Unfortunately I don't remember the switches you need for that, you have to search Apple's documentation.

[Yury V. Zaytsev (zyv)]

Didn't Apple guys strip all the supporting 32-bit binaries from Snow Leopard?

[Jussi Pakkanen (jpakkane)]

No, because that would mean that every 32 bit binary (which is to say roughly 99% of all third party applications ever produced for OS X) would break.

[Tax Man (taxman457f)]

I'm not sure I did enough, but I put -arch i386 in the following places in CMakeCache.txt. It was indicated by this: http://developer.apple.com/mac/library/documentation/Darwin/Conceptual/64bitPorting/building/building.html

//Flags used by the compiler during all build types.
CMAKE_CXX_FLAGS:STRING=-arch i386

//Flags used by the compiler during all build types.
CMAKE_C_FLAGS:STRING=-arch i386

However, http://boomswaggerboom.wordpress.com/2009/08/27/building-32-bit-firefox-on-mac-os-x-10-6/ seems to imply there needs to be more of a crossbuild. Maybe that is specific to that project.

Anyway, I still get the seg fault. Do you want to see the backtrace?

Also, the linux build I tested on above is a 32 bit Ubuntu 9.04 machine and it is also seg faulting.

[Jussi Pakkanen (jpakkane)]

Please attach the image. Also post all the exact commands you execute to build and run Cuneiform starting from checking out the source.

Just experienced same issue on OS X 10.6.2. Overcame it with 32bit gcc-4.0 from 10.5 compatibity layer:

CXX=g++-4.0 CC=gcc-4.0 cmake -DCMAKE_BUILD_TYPE=Debug ..

works perfect.

Hello everybody,
It seems that @inye at least managed to compile and run cuneiform on Mac.
However I’m still getting the segmentation fault...
I don’t know how to build Cuneiform from source, therefore I have installed it via MacPorts

# sudo port install cuneiform

Now, whenever I run it, I get "Segmentation fault" error:

# cuneiform -f hocr test.html test.tif
# Cuneiform for Linux 1.0.0
# Segmentation fault

I’ve got XCode and all the tools in order to build the application from its source files, but I don’t know how to do...
By the way, I’m using the latest 13" MacBook Air with OS X 10.6.7 — could anybody tell me how I can compile Cuneifrom?
Or better, if it is possible, send me his/her binary builds?

Thank you in advance,
Best wishes.

$ ./configure
$ make
$ sudo make install

It's as simple as that. Worked for me at Lion.

[Yury V. Zaytsev (zyv)]

Where did you get the ./configure thing from? Cuneiform build system is generated using CMake, your instructions are arbitrary. See example in the README file.
