| Subject: | warnings during build and test fails |
I just installed L-I-W and noticed some warnings while it was building:
Checking if your kit is complete...
Looks good

I don't know if they matter but the test fails. Note that I'm on a
64-bit AMD machine. The libwiimote tests do work. When I run the test
after adding my wiimote address, it runs and I see
my-prompt$ ./test.pl
test.pl - libcwiimote perl module test application
A - hold to Enable accelerometer
1 - hold to Enable rumble
Home - Exit
Press buttons 1 and 2 on the wiimote now to connect.
When I press those buttons the program exits immediately and I see:
Connect 0
-------------------------------
my-prompt$
Presumably the undocumented method wiimote_is_open() is returning false.
I added a call to warn in the loop and it didn't print anything. I'll
see if I can find out more but I'm not very familiar with XS.
My perl is:
