I'm no expert, but this is what got me up and running:

Solaris 10/sparc, db-4.4.20, and openldap-2.2.23.  I had all the right env vars set...or so I thought..and was compile, using a precompiled gcc 3.3.2 package.

checking for db.h... yes
checking for Berkeley DB link (default)... no
checking for Berkeley DB link (-ldb44)... no
checking for Berkeley DB link (-ldb-43)... no
checking for Berkeley DB link (-ldb-4.3)... no
checking for Berkeley DB link (-ldb-4-3)... no
checking for Berkeley DB link (-ldb42)... no
checking for Berkeley DB link (-ldb-42)... no
checking for Berkeley DB link (-ldb-4.2)... no
checking for Berkeley DB link (-ldb-4-2)... no
checking for Berkeley DB link (-ldb-4)... yes
checking for Berkeley DB version match... no
configure: error: Berkeley DB version mismatch

When I looked closely at the config.out, I noticed this:

configure:18061: checking for db.h
configure:18071: gcc -E -I/usr/local/BerkeleyDB.4.4/include -I/usr/local/ssl/inc

which indicated the configure script didn't automatically add -ldb to tell the compiler to actually USE the Berkeley database althought it certainly detected it (enough to make the mismatch error).

So, in addition to the good advice on the Internet from everyone to use CC, CFLAGS, CPPFLAGS, and LDFLAGS, I needed to explicitly define LIBS.  (More on this in a sec.)

setenv LIBS -ldb


I also ran into a "file not found" error for libgcc_s.so.1:

gcc -I/usr/local/BerkeleyDB.4.4/include -I/usr/local/ssl/include -I/usr/local/include -I/usr/include -o ucgendat ucgendat.o  -L/usr/local/BerkeleyDB.4.4/lib -L/usr/local/ssl/lib -L/usr/local/lib ../../libraries/liblber/.libs/liblber.a ../../libraries/liblutil/liblutil.a -lresolv -lgen -lnsl -lsocket -ldb -lgcc_s -R/usr/local/BerkeleyDB.4.4/lib -R/usr/local/ssl/lib -R/usr/lib

*** Signal 9
make: Fatal error: Command failed for target `ucgendat'
Current working directory /opt/src/openldap-2.2.23/libraries/liblunicode
*** Error code 1

So in the end, I used:

setenv LIBS "-ldb -lgcc_s"


Lastly, I also saw a cross compile error:

checking for LinuxThreads consistency... no
checking if pthread_create() works... yes
checking if select yields when using pthreads... cross
configure: error: crossing compiling: use --with-yielding_select=yes|no|manual

I turned off cross compiling in the configuration step.

The "make test" worked just fine.
