[ts-7000] gpio problems.

[Rodrigo Gómez <>]

I`m trying to discover how gpio interrupts works. I'm compiling the 
andy's code :
gps_pps.tgz 
Example device driver that shows how to use GPIO and the GPIO IRQ 

after I compile (with make) the compiler sends and error:


ts7200:/develop/ejemplosCodigo/gpio/gps_pps# make
/usr/bin/gcc -B/usr/bin -isystem /usr/include -I /usr/include -
L /usr/lib  -Wno-
trigraphs -Os -mshort-load-bytes -fno-strict-aliasing -fno-common -
Uarm -pipe -m

gps_pps.c:206: warning: return-type defaults to `int'
gps_pps.c: In function `irq_handler':
gps_pps.c:217: `IRQ_HANDLED' undeclared (first use in this function)
gps_pps.c:217: (Each undeclared identifier is reported only once
gps_pps.c:217: for each function it appears in.)
gps_pps.c:220: `IRQ_NONE' undeclared (first use in this function)
gps_pps.c:221: warning: control reaches end of non-void function
gps_pps.c: In function `initialize_hardware':
gps_pps.c:234: warning: passing arg 2 of `request_irq' from 
incompatible pointer
 type
gcc: file path prefix `/usr/bin' never used
make: *** [obj/gps_pps.o] Error 1
ts7200:/develop/ejemplosCodigo/gpio/gps_pps#

I guess my system lacks of a library that have the IRQ_HANDLED and 
IRQ_NONE  definitions, I'm running in ts-7250 with the cross chain 
included in the USB memory that runs a debian stable shell.

Any help would be greatly apreciated
