Building Berkeley DB from source, and building Postfix according to

This expects /scratch/local2/berkeley-db/lib/libdb.so*
It’s present:

bin/postconf: error while loading shared libraries: libdb-5.3.so: cannot open
shared object file: No such file or directory
So where does the -5.3 in the complaint comne from? If it wasn't
specified at Postfix build time, where else can it be?
`libdb.so` and `libdb-5.so` are symbolic links to `libdb-5.3.so`.
To my knowledge, as building succeeds, it’s not a problem with the
specified library.
$ ldd ./bin/postconf
linux-vdso.so.1 (0x00007ffd9d97f000)
libdb-5.3.so => not found
[…]
$ LD_LIBRARY_PATH=/scratch/local2/berkeley-db/lib ldd ./bin/postconf
linux-vdso.so.1 (0x00007ffd9f3a8000)
libdb-5.3.so =>

You may need to specify -ldb-5.3, given that your file is in
a non-default place.
make makefiles CCARGS="-DHAS_DB -I/scratch/local2/berkeley-db/include" \
AUXLIBS="-L/scratch/local2/berkeley-db/lib -ldb-5.3"
That results in the same issue. At least from other software, I now,
that the runtime library path needs to be set either by
`LD_LIBRARY_PATH` or `-rpath`.
And, surprise, the Postfix 3.x build for Linux specifies -rpath.
You override the Postfix build system at your own risk.
I am following the instructions in `DB_README` [1]. ;-)
Could you please point me to the code? I am not seeing it. I found
`SHLIB_RPATH` [1] before, but I do not override it, and reading the
description I thought it’s for the shared libraries generated by Postfix
`libpostfix-*.so.*`.
SHLIB_RPATH=rpath
Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'")
for Postfix dynamically-linked libraries.
This feature was introduced with Postfix 3.0.
Would you accept a patch to add fix the instructions in `DB_README`?
Kind regards,
Paul
