[pwc] Trouble compiling on Ubuntu 10.04

[Alistair Frith <>]

Hi all, just joined the list as I have an SPC880 (flashed to SPC900) and I want to use it on Linux to do astrophotography.

I am having problems compiling the driver. I get the following error when making either pwc-10.0.11 or pwc-10.0.12-rc1:

:~/Downloads/spc900/pwc-10.0.12-rc1$ make
make -C /lib/modules/2.6.32-21-generic/build SUBDIRS=/home/alistair/Downloads/spc900/pwc-10.0.12-rc1 modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.32-21-generic'
  CC [M]  /home/alistair/Downloads/spc900/pwc-10.0.12-rc1/pwc-if.o
In file included from /home/alistair/Downloads/spc900/pwc-10.0.12-rc1/pwc-if.c:69:
/home/alistair/Downloads/spc900/pwc-10.0.12-rc1/pwc.h:28:26: error: linux/config.h: No such file or directory
/home/alistair/Downloads/spc900/pwc-10.0.12-rc1/pwc.h:37:27: error: asm/semaphore.h: No such file or directory
/home/alistair/Downloads/spc900/pwc-10.0.12-rc1/pwc-if.c:166: error: variable ‘pwc_template’ has initializer but incomplete type
... (lots more errors)

I assume all of these errors can be fixed by installing something or making a couple of changes. I have searched for config.h:

:~/Downloads/spc900/pwc-10.0.12-rc1$ sudo find / -name config.h -print
/usr/lib/grub/i386-pc/config.h
/usr/lib/perl/5.10.1/CORE/config.h
/usr/src/linux-headers-2.6.32-21-generic/include/config/i2o/config.h
/usr/src/linux-headers-2.6.31-17-generic/include/config/i2o/config.h

Non of these are under a 'linux' directory. I am wondering whether I need to make a symbolic link somewhere?

I am running kernel 2.6.32-21:

:~/Downloads/spc900/pwc-10.0.12-rc1$ uname -r
2.6.32-21-generic

The linux headers appear to be installed:

:~/Downloads/spc900/pwc-10.0.12-rc1$ sudo apt-get install linux-headers-$(uname -r)

As is the source:

:~/Downloads/spc900/pwc-10.0.12-rc1$ sudo apt-get install linux-source-2.6.32

Any suggestions would be very gratefully received
