gentoo linux-headers package no longer installs asm/user.h, asm/page.h and i386-asm/user.h. mono-debugger requires 3 struct definitions in i386-asm/user.h which requires the other two header files.

Created attachment 123162 [details, diff] patch to add struct definitions to backend/server/i386-arch.h adds missing struct definitions from i386-asm/user.h
(In reply to comment #1) > Kindly review http://bugs.gentoo.org/page.cgi?id=fields.html#bug_severity > Sorry about that. Guess it should be normal severity...
I suppose you're using ~keyworded linux-headers (>=2.6.19)? With stable 2.6.17 this is bug does not occur
(In reply to comment #4) > I suppose you're using ~keyworded linux-headers (>=2.6.19)? With stable 2.6.17 > this is bug does not occur > Yes, ~x86, which is how mono-debugger-0.50 is keyworded. linux-headers-2.6.21 kernel 2.6.21-suspend2-r6
Agreed, but using ~keyworded mono-debugger does not imply using ~keyworded linux-headers (or any other dependencies). Your patch looks good but nevertheless you should add some conditional code to it (e.g. based on '#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,19)')
Created attachment 123173 [details, diff] cleaned up i386-arch.h patch Cleaned up the original patch. Added code for conditional compilation on machines with linux-headers >= 2.6.19. Earlier versions will still #include <asm/user.h>.
Fixed in CVS, thanks
