Hi,
I recently had a problem compiling pcmcia-cs-3.1.3, the following message describes it almost perfectly, I assume Tsuneya had a slightly different version of pcmcia-cs as my line numbers were slightly different. I'm using linuxppc (approx RH6) on a Wallstreet Powerbook. I maybe missing something completly obvious, but looking at the code, the structure socket_info_t defined in cs_internal.h is defined without the member 'spinlock_t lock' if USE_SPIN_LOCKS isn't defined (and it probably shouldn't be). It is then referenced in cs.c in several places where a variable of type socket_info_t is used to access 'lock'. whether or not USE_SPIN_LOCKS is defined (as far as I can tell). Compilalition then fails. This all seems internal to pcmcia-cs. I don't see how it is caused by the kernel spinlock header. Anyway, apologize for any boneheadness on my part in advance...
