hello, i was able to get this to work. the problem has something to do with the DEFINE_RWLOCK macro. replaced 3 calls to DEFINE_RWLOCK with the equivalent declarations based on the macro itself (rwlock_t x = ...) and it compiled and worked fine.

i'm trying to build a new version of alsa (1.0.11rc3 but i also tried 1.0.10 stable) for a rhel4 workstation (to enable ca0106) and it builds okay with the rhel4u2 kernel (2.6.9-22.0.2.EL) but there is an issue when building against 2.6.9-34.EL. the first issue is that gfp_t seems to be defined in 2.6.9-34 even though include/adriver.h declares it for all versions < 2.6.14. i commented out the include/adriver.h declaration and get a bit further but it still dies. this is on x86_64. has anyone seen this problem? thanks in advance for your help.
here's the output:
