Richard, For me it looks like your kernel has ALSA included into source tree already. It is only a guess -- I dont have a lny linux in hands right now but you can check it with something like: find /usr/src/linux/ | xargs grep -sqi alsa && echo yes I have ALSA in kernel NB: i haven't try this but should work horsh ==================8<=========================== Hallo, Richard hat gesagt: // Richard wrote: ... Well, this is a bit strange. I'm guessing a bit now: The offending lines in your example result from adriver.h defining things for some kernel versions, including kernel 2.4.22. For example the error regarding PDE: /home/ric/alsa-driver-0.9.7c/include/adriver.h:134: error: redefinition of `PDE '/lib/modules/2.4.22-1.2097.nptl/build/include/linux/proc_fs.h:17: error: `PDE' previously defined here This means, that somewhere in "include/linux/proc_fs.h" the name PDE is already defined. In adriver.h ALSA tries to define it on its own like this: #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 5, 4) #include <linux/fs.h> static inline struct proc_dir_entry *PDE(const struct inode *inode) { ... #endif The strange thing is, that in my rather vanilla version of kernel 2.4.22 there is no such thing as PDE in include/linux/*: $ grep PDE /usr/src/linux/include/linux/proc_fs* $ (nothing here) So I suspect, but I can only guess here, that your kernel source has a patch that introduces this PDE thing (I have no idea what it could be used for). I don't know if ALSA could fix that at all. It might be, that if Fedora ships a custom Linux kernel source, they should also provide adapted ALSA-sources. ciao -- Frank Barknecht _ ______footils.org__
