Hello, I am working to install cyrus-imap v 2.0.13 on a tru64 UNIX v5.1 system. So far I have installed everything you recommend except gcc. I prefer to use the native compilers if at all possible. When I run ./configure, this is the output I recieve: # ./configure --prefix="/imap/cyrus" --with-cyrus-prefix="/imap/cyrus" --with-auth=unix --with-dbdir="/usr/local/BerkeleyDB.3.2" loading cache ./config.cacheocal/BerkeleyDB.3.2" checking host system type... alpha-dec-osf5.1 checking for makedepend... makedepend checking for gcc... no checking for cc... cc checking whether the C compiler (cc ) works... yes checking whether the C compiler (cc ) is a cross-compiler... no checking whether we are using GNU C... no checking whether cc accepts -g... yes checking for ranlib... ranlib checking whether make sets ${MAKE}... yes checking for a BSD compatible install... ./install-sh -c checking how to run the C preprocessor... cc -E checking for AIX... no checking for POSIXized ISC... no checking for mawk... no checking for gawk... no checking for nawk... nawk checking for working const... yes checking for long file names... yes checking for runpath switch... -Wl,-rpath, checking for unistd.h... yes checking for sys/select.h... yes checking for sys/param.h... yes checking for memmove... yes checking for strcasecmp... yes checking for ftruncate... yes checking for strerror... yes checking for dirent.h that defines DIR... yes checking for opendir in -ldir... no checking whether struct tm is in sys/time.h or time.h... time.h checking for tm_zone in struct tm... yes checking for vprintf... yes checking for db_create in -ldb-3... no checking for db_create in -ldb... no configure: error: this version requires Berkeley DB 3.x. (Get it from http://www.sleepycat.com/.) Berkeley DB is installed in /usr/local/BerkeleyDB.3.2 Here is a full listing of that directory and its subdirectories (excluding the docs subdirectory): # cd /usr/local/BerkeleyDB.3.2/ # ls -lR total 32 drwxr-xr-x 2 root system 8192 May 30 12:01 bin drwxr-xr-x 10 root system 8192 May 30 12:02 docs drwxr-xr-x 2 root system 8192 May 30 12:01 include drwxr-xr-x 2 root system 8192 May 30 12:24 lib ./bin: total 6544 -r-xr-xr-x 1 root 100 663616 May 30 12:01 db_archive -r-xr-xr-x 1 root 100 655424 May 30 12:01 db_checkpoint -r-xr-xr-x 1 root 100 655424 May 30 12:01 db_deadlock -r-xr-xr-x 1 root 100 663616 May 30 12:01 db_dump -r-xr-xr-x 1 root 100 680000 May 30 12:01 db_load -r-xr-xr-x 1 root 100 655424 May 30 12:01 db_printlog -r-xr-xr-x 1 root 100 655424 May 30 12:01 db_recover -r-xr-xr-x 1 root 100 680000 May 30 12:01 db_stat -r-xr-xr-x 1 root 100 655424 May 30 12:01 db_upgrade -r-xr-xr-x 1 root 100 655424 May 30 12:01 db_verify ./include: total 69 -r--r--r-- 1 root 100 51180 May 30 11:52 db.h -r--r--r-- 1 100 100 19263 Jan 12 07:28 db_cxx.h ./lib: total 1480 -r--r--r-- 1 root 100 1514744 May 30 12:00 libdb.a At this point I am stuck. configure is insisting I install something I have installed. I haved renamed the libdb.a and db.h provided by Digital and linked /usr/lib/libdb.a and /usr/inlude/db.h to the appropriate files in /usr/local/BerkeleyDB.3.2 but that hasn't helped either. help. Can anyone give any advice, or point me to where I can get advice from someone else. thanks in advance clare
