Re: Compiling OpenLDAP with static SASL library

[... re static sasl build ...]

Below is what I did and the problems I encounter.

Naturally, the gcc error message pointed you in the wrong direction, I think. To start with, I think you should `make clean' your cyrus-sasl and build it again the first way (without -fPIC.) If it's the same to you, I would add --disable-shared at this point, but at any rate, the installed lib/ directory should have only the .a static library, no .so.

Then use LDFLAGS to specify that location: -L/home/zohar/dev/cyrus- sasl-2.1.22/lib

If I'm right, the problem is that `configure' has added an -lsasl2, and
the first library found to satisfy that is /usr/lib/libsasl2.so - gcc didn't
notice that you specified another version of this library as a file path.
Of course I haven't tested this theory.

When all else fails, I have in the past copied the gcc command at issue out
of my make log, and edited out the configure problems. That isn't likely
to be a satisfactory solution, but it can at least give you an idea of what
magic combination will work, and then you can apply your efforts to making
configure produce that configuration.

cyrus-sasl: cyrus-sasl-2.1.22
OpenLDAP: openldap-2.3.24
OS: Red Hat Enterprise Linux ES release 4 (Nahant Update 3)

I configured and compiled cyrus-sasl like this:
$ ./configure --enable-static --prefix=/home/zohar/dev/cyrus- sasl-2.1.22
$ make

Then I configured and compiled OpenLDAP like this:
$ ./configure --prefix=/home/zohar/dev/openldap-2.3.24
$ make depend
$ make

I got the following error:

/home/zohar/dev/cyrus-sasl-2.1.22/lib/libsasl2.a: could not read

So I went back to cyrus-sasl and re-configured it like this:
$ ./configure --enable-static=yes
--prefix=/home/zohar/dev/cyrus-sasl-2.1.22 CFLAGS=-fPIC
$ make

And recompile OpenLDAP. Now I got this error:

collect2: ld returned 1 exit status

So I went back again re-configured and compiled OpenLDAP with the
libraries defined in libsasl2.la:
$ make distclean
$ ./configure --prefix=/home/zohar/dev/openldap-2.3.24
LDFLAGS="/home/zohar/dev/cyrus-sasl-2.1.22/lib/libsasl2.a -L/usr/lib64
-ldl -lresolv -lcrypto -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err
-lcrypt -ldb-4.2 "
$ make depend
$ make

That part compiles, but when I checked the dependencies I saw this:
$ ldd servers/slapd/slapd
libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2
libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x0000003ed6800000)

libz.so.1 => /usr/lib64/libz.so.1 (0x0000003ed3a00000)

As you can see, the system sasl2 is linked to slapd, the problem arise
from the configure script where it is defined there the -lsasl2 and
-lsasl, that is why I asked about configure and Makefile.

Any help will be appreciated.

That's what I do, but I don't need to modify any of these files, for Red Hat Linux or NetBSD. I build my own Cyrus SASL library, static only, and simply specify its location in the LDFLAGS environment variable when I invoke the OpenLDAP configure.

Having trouble with it?
