Patches for DB version 2.4.10

  1. Problem: The DB 2.4.10 release fails to compile on SunOS reporting the errors:

     

    "../dist/../common/db_region.c", line 755: SEEK_END undefined
"../dist/../common/db_region.c", line 787: SEEK_CUR undefined
"../dist/../log/log.c", line 354: SEEK_SET undefined
"../dist/../log/log_get.c", line 218: SEEK_SET undefined
"../dist/../log/log_put.c", line 432: SEEK_SET undefined
"../dist/../mp/mp_bh.c", line 154: SEEK_SET undefined
"../dist/../mp/mp_bh.c", line 345: SEEK_SET undefined

    Apply the following patch to the db-2.4.10 include/db_int.h.src file. (Note, this patch must be applied before configuring Berkeley DB.)

  3. Problem: Deleting a key in a hash database can cause a cursor sequentially walking the database to skip records.
    Apply the following patch to the db-2.4.10 hash/hash_page.c file.

  4. Problem: The DB 2.4.10 release fails to compile on FreeBSD-2.2.6-current, reporting that the "ftok" symbol is undefined.

    The ftok(3) routine is found in libcompat.a on FreeBSD-2.2.6-current. Modify the "LIBS=" line in the build directory Makefile to include libcompat.a.

     

  5. Problem: The DB 2.4.10 release fails to compile, reporting that there are conflicting types for "mmap" or "munmap": 
    cc -c -O -I. -I../dist/../include ../dist/../os/os_config.c
*** Error code 1
../dist/../os/os_config.c:52: conflicting types for `mmap'

    Apply the following patch to the db-2.4.10 os/os_config.c file.
