Potential Build Issue about vowpal_wabbit

[arielf]

Hi there,

It is not your fault. Recent code added to searn doesn't build cleanly across platforms. While most of the above are just warnings, there's at least one compile error that prevents the build from completing on your (32-bit?) platform.

Two possible work arounds:

1. switch to a 64-bit system
2. git checkout an older version of the code that can build cleanly, e.g. go back to circa April 29:

     git checkout 5a8871b8
     make clean
     make
     make test

Hi Airelf,

I'm new to GitHub. I've only used Git Bash and "git clone".

I tried "git checkout git://github.com/JohnLangford/vowpal_wabbit/commit/5a8871b8" but I get
"fatal: Not a git repository (or any of the parent directories): .git"

how do I checkout an older version?

Thank you for your help.

You need to do the checkout in an already cloned repository (the one you already have).
The argument to git checkout is only the commit id (as specified above)

Checked out '5a8871b8'
Head is now at 5a8871b

make test fails; however, I see that vw.exe has now appeared, unlike before.

vw running test-suite...
(cd test && ./RunTests -d -fe -E 0.001 ../vowpalwabbit/vw ../vowpalwabbit/vw)
/usr/bin/env: perl: No such file or directory
Makefile:85: recipe for target 'test' failed
make: *** [test] Error 127

I believe this is fixed. Hal, I renamed the predict predictLDF to deal
with the name collision between a uint32_t ystar and a size_t example_count.

Ray,
To run the tests, you will need perl installed.
Anyway, your executable has now built successfully so I think you should be good to play with it.

I'm excited! Thank you for your help, Ariel.
