[libhid-discuss] Compiling on Raspbian / Debian Wheezy

[Florian Rittmeier]

Hello,

I just wanted to share, that I had troubles compiling libhid 0.2.16 from 
the tarball on a RaspberryPi running Raspbian (Debian Wheezy).

The trouble was caused by a warning issued from compiling test/lshid.c 
during "make". The warning, which was treated as error, was caused by 
the parameter len which was detected as not beeing used. This seems to 
be known as there is some workaround in the device_iterator function in 
test/lshid.c which tries pretend that len is used.

I don`t know why this is a problem now and was not before. Perhaps the 
gcc is getting wiser. ;-) As a solution I added to following line right 
below the existing workaround:
if(len){}

The compiler accepted this, the warning does not get issued anymore and 
libhid was successfully build.

Regards,
Florian
