Package: libc0.2-dev Version: 2.1.2-0pre12 I was starting to work on apt support on the Hurd.
Apt makes use of the msync function, which I see is supported in the Hurd (according to the sys/mman.h file). When I attempt to compile, however, I get complaints about the use of MS_SYNC (undefined). Sure enough, the sys/mman.h doesn't define this, and neither does bits/mman.h. On Linux, the various flag values for msync are defined in /usr/include/asm/mman.h. We don't seem to have anything similar (except perhaps bits/mman.h) unless I have forgotten to reinstall some development package. Should the MS_* macros be included in bits/mman.h? It seems like other things (found in /usr/include/asm/mman.h on Linux) are defined here. Here are the definitions (under Linux): #define MS_ASYNC 1 /* sync memory asynchronously */ #define MS_INVALIDATE 2 /* invalidate the caches */ #define MS_SYNC 4 /* synchronous memory sync */ Thanks, -Brent
