Hi
I am actually compiling backend modules for openldap 2.4.26 with MingW (gcc
version 4.6.1, GNU make 3.81, GNU libtool 2.4, GNU automake 1.11.1, GNU autoconf
2.68.
An issue occurs when compiling back-ldap module.
The GNU tools used are the following :
        host-triplet:   i686-pc-mingw32
        shell:          /bin/sh
        compiler:               gcc
        compiler flags:         -O3 -s -mms-bitfields -march=i386 -mtune=i686
        linker:         c:/mingw/mingw32/bin/ld.exe (gnu? yes)
        libtool:        (GNU libtool) 2.4
        automake:       automake (GNU automake) 1.11.1
        autoconf:       autoconf (GNU Autoconf) 2.68
The command line to compile openldap 2.4.26 is the following
./configure --prefix=/software/openldap \
        --enable-slapd \
        --enable-modules \
        --enable-rewrite \
        --enable-bdb=mod \
        --enable-hdb=mod \
        --enable-ldap=mod \
        --enable-sql=mod \
    --enable-monitor=mod \
        --enable-accesslog=mod \
        --enable-auditlog=mod \
        --enable-rwm=mod \
    --enable-syncprov=mod \
        --with-odbc=odbc32 \
        --with-tls=openssl \
        --without-cyrus-sasl
Here are the compilation flags :
CPPFLAGS="-I/software/openssl/include
-I/software/berkeleydb/berkeleydb-5.2/include"
LDFLAGS="-I/software/openssl/lib -I/software/berkeleydb/berkeleydb-5.2/lib"
LIBS="-lodbc32 -lws2_32"
All backends modules and overlays compile fine but when compiling backend
back-ldap as a module, the following compile error occurs : error: initializer
element is not constant.
$ make
/bin/sh ../../../libtool --tag=disable-static --mode=compile gcc -g -O2

                        "olcChainReturnError "
                        ") )",
                Cft_Overlay, chaincfg, NULL, chain_cfadd },
        { "( OLcfgOvOc:3.2 "
                "NAME 'olcChainDatabase' "
                "DESC 'Chain remote server configuration' "
                "AUXILIARY )",
                Cft_Misc, olcDatabaseDummy, chain_ldadd
#ifdef SLAP_CONFIG_DELETE
                , NULL, chain_lddel
#endif
        },
        { NULL, 0, NULL}
};
I try to solve this problem but I'm a little stuck. When back-ldap is not
compiled as a module, no problem, slapd compiles fine with this backend
back-ldap.
Best regards and many thanks to you.
