I'd still like to see db3 setup like db2:
includes in /usr/include/db3
links in /usr/include
This is the path used in the first of the 2.4.2-acx kernels - so I
assume (yeah, I know) that its may be a more standard location.
My autoconf process now is:
#
# Check for presence of NEWDB headers
#
CPPFLAGS=""
AC_CHECK_HEADERS(db3/db.h)
AC_SUBST(ac_cv_header_db3_db_h)
AC_CHECK_HEADERS(db2/db.h)
AC_SUBST(ac_cv_header_db2_db_h)
AC_CHECK_HEADERS(db.h)
AC_SUBST(ac_cv_header_db_h)
Then, the m4 uses those values thusly:
define(`ac_cv_header_db3_db_h', `@ac_cv_header_db3_db_h@')dnl
define(`ac_cv_header_db2_db_h', `@ac_cv_header_db2_db_h@')dnl
define(`ac_cv_header_db_h', `@ac_cv_header_db_h@')dnl
ifelse(ac_cv_header_db3_db_h, `yes',
`APPENDDEF(`confINCDIRS', `-I/usr/include/db3')'
`APPENDDEF(`conf_sendmail_LIBS', `-ldb3')'
ac_cv_header_db2_db_h, `yes',
`APPENDDEF(`confINCDIRS', `-I/usr/include/db2')'
`APPENDDEF(`conf_sendmail_LIBS', `-ldb2')'
ac_cv_header_db_h, `yes',
dnl `APPENDDEF(`confINCDIRS', `-I/usr/include')' #not needed
`APPENDDEF(`conf_sendmail_LIBS', `-ldb')'
)
All this is done to figure out how to compile sendmail.... sendmail
itself uses the things you mentioned above for determining the db
version (it supports db1, db2, and db3).
I'm (for the nonce) at a loss as how to fit db3 in without there being a
/usr/include/db3 path...
