win32/ [BUG] Segmentation fault

Added by newmonkey (Sylvain Pelissier) over 9 years ago. Updated almost 9 years ago.



I run 'gem install win32-process' on Windows 7 64-bit and it comes with a win32-api that is pre-compiled for x86 machines. I don't know for sure if this is the best place to request such thing but I would like to have a pre-compiled version of that library for my OS.

Context: I am using selenium web driver (selenium-server-standalone-2.0a5.jar) from within Eclipse Galileo, including DLTK 2.0. This enables me to create ruby scripts to automate/drive web browsers.

Problem: It's working fine under ruby 1.8.7, but if I use ruby 1.9.1, then I get a seg fault (see attached). According to the only post I found in the Internet, this is because the win32-api libraries I can access via ruby gem is pre-compiled with x86 machines in mind. I have not found anywhere the library for a 64 bit Windows OS. And I am not sure how to compile it from source under Windows...

Solution: when I run the command gem install win32-process on this 64-bit Windows 7 machine, I should get the files for the corresponding architecture.

-Thank you-

This is a 3rd party issue.

win32-utils bugs should be reported to their project:

And one of the developers with the Git repositories is at GitHub:

Look over there and provide him a patch.

Your issue is actually that the binary is linked to Ruby 1.8 and not 1.9, the internal Ruby API changes can generate a segfault when a 1.8 extension is executed under 1.9.
