Errors in Makefile of "Blinking a LED" example

[majesty-dump]

I got next errors while making Blinking a LED example: root@beaglebone:/home/debian/PRUCookbook-master/docs/02start/code# make Makefile:1: *** missing separator. Stop.

After the first error i had copied makefile from "../../03details/code/Makefile" manually and tried to use "make" command again:

root@beaglebone:/home/debian/PRUCookbook-master/docs/02start/code# make

• Stopping PRU 0 stop CC hello.c "resource_table_empty.h", line 1: warning #1-D: last line of file ends without a newline "resource_table_empty.h", line 1: error #171: expected a declaration "hello.c", line 12: warning #12-D: parsing restarts here after previous syntax error "hello.c", line 28: error #20: identifier "GPIO1_CLEAR" is undefined 2 errors detected in the compilation of "hello.c".

Compilation failure Makefile:56: recipe for target '/tmp/pru0-gen/hello.obj' failed make: *** [/tmp/pru0-gen/hello.obj] Error 1

Is it only new BeagleBone Black Kernel's problems?

UPDATE:

In the end, I copied the resource_table_empty.h and Makefile files from the 03details and 05blocks folders , which paths were codded in the simillar files but in the 02start folder. After all of that, the compilation was completed, but now I get the following warning every time i try to run Makefile: make: Warning: File 'Makefile' has modification time 2162757 s in the future

I'll check into this next week. I'd like to know what's happening.

Thanks for pointing it out.

Hmmm.... It's working for me.

The last warning

make: Warning: File 'Makefile' has modification time 2162757 s in the future

is probably your clock on the Bone isn't set. What does the 'date' command say?

p.s. Did your source the setup.sh file first?

bone$ source setup.sh
#!/bin/bash
export PRUN=0
export TARGET=hello
echo PRUN=$PRUN
echo TARGET=$TARGET
bone$ make
-    Stopping PRU 0
stop
CC  hello.c
LD  /tmp/pru0-gen/hello.obj
-   copying firmware file /tmp/pru0-gen/hello.out to /lib/firmware/am335x-pru0-fw
-    Starting PRU 0
start

I'm pushing out a new version where this should work. Check it out and reopen if it doesn't.
