gcc error: expected ‘)’ before ‘*’ token

[g.a.]

Hi,

I get a gcc error when trying to compile some example code of a usb device. I'm using kubuntu 7.10 and gcc 4:4.1.2-9ubuntu2

This is the error:

gcc -g -Wall -c -o pmd.o pmd.c
pmd.c:41: error: expected ‘)’ before ‘*’ token
pmd.c:63: error: expected ‘)’ before ‘*’ token
pmd.c:86: error: expected ‘)’ before ‘*’ token
pmd.c:102: error: expected ‘)’ before ‘*’ token
make: *** [pmd.o] Error 1

and inthe following I copy the pmd.c file (the simles denotes the failed lines). The code obviously worked for the people that released it. Any suggestion?

thanks in advance,
g.

The '*' it chokes on appears to be HIDInterface*
Dig into how that is defined in the headers.

thanks for the reply. I downloaded a different version of the files, reinstalled the libraries and compiled without problems.

thanks,
