Subject: Re: [exim] Building exim manually on Freebsd 10.1 AMD 64 ld: cannot

How ever on the freebsd 10.1 amd 64 version the following happens
I use this platform.
after running make clean ; make makefile; make
gcc -o exim
/usr/local/bin/ld: cannot find -llber
The `lber` library is part of OpenLDAP. The relevant part of the
FreeBSD Port Makefile is:
----------------------------8< cut here >8------------------------------
.if ${PORT_OPTIONS:MOPENLDAP}
LDAP_LIB_TYPE= OPENLDAP2
SEDLIST+= -e
's,XX_LDAP_LIBS_XX,-L${LOCALBASE:S/,/\\,/g}/lib -llber -lldap,' \
-e 's,XX_LDAP_INCLUDE_XX,-I${LOCALBASE:S/,/\\,/g}/include,'
\
-e 's,XX_LDAP_TYPE_XX,${LDAP_LIB_TYPE:S/,/\\,/g},' \
-e 's,^\# (LOOKUP_LDAP=),\1,'
.else
SEDLIST+= -e 's,XX_LDAP_[^ ]*_XX,,' \
-e 's,^(LDAP_LIB_TYPE=),\# \1,'
.endif
----------------------------8< cut here >8------------------------------
Those XX values come from applying files/patch-src__EDITME to Exim's
source. The relevant lines are:
+LDAP_LIB_TYPE=XX_LDAP_TYPE_XX
+LOOKUP_INCLUDE=XX_MYSQL_INCLUDE_XX XX_PGSQL_INCLUDE_XX XX_LDAP_INCLUDE_XX
+LOOKUP_LIBS=XX_MYSQL_LIBS_XX XX_PGSQL_LIBS_XX XX_LDAP_LIBS_XX
So, when building manually, you need to put these in Local/Makefile:
LDAP_LIB_TYPE=OPENLDAP2
LOOKUP_INCLUDE=-I/usr/local/include
LOOKUP_LIBS=-L/usr/local/lib -llber -lldap
In particular, because OpenLDAP is not part of the base system, the
libraries are not in the default ld(1) search path for linking the
object files into the final binary. They're installed by Ports into
/usr/local, so you need to use -I and -L to tell the compiler where they
are.
Scratching around on google others have had the same problem and I tried
the following before coming asking for help.
[email protected] / # /usr/bin/ld -lsasl2
/usr/bin/ld: warning: cannot find entry symbol _start; not setting start
address
//lib/libc.so.7: undefined reference to `__progname'
//lib/libc.so.7: undefined reference to `environ'
The `ld` program is the linker; it takes object files (from compilation)
and libraries, figures out how to glue all the parts together and makes
the executable program which you can then run. It needs a program to
provide a main() function; if you only give it libraries, there is no
main program and it can't figure out where execution should start. So
the command-line which you tried is asking for something peculiar and
the tool failed when it tried to do exactly what you asked for.
The Exim build process will invoke ld for you, using various ${FOO}_LIBS
or EXTRALIBS values as appropriate. In this case, LOOKUP_LIBS would be
used.
I have also done the following
ln -s /usr/local/lib/libsasl2.so /usr/lib/libsasl2.so
ln -s /usr/local/bin/gcc48 /usr/local/bin/gcc
Undo both of these.
