Dears,

I try to compile 2.5.7 version with --enable-perl module but I get issue as following :

First issue I get :

In file included from init.c:18: perl_back.h:21:10: fatal error: EXTERN.h: No such file or directory #include <EXTERN.h> ^~~~~~~~~~ compilation terminated. make[3]: *** [Makefile:334: init.lo] Error 1

To solve above issue, I had to install a missing rehl package (perl-devel.x86_64) and set CPPFLAGS=-I/usr/lib64/perl5/CORE/ of the "configure utility".

I did :

Make distclean Configure Make depend make

Then "make" goes further but now I get a lot of entries as below then it stopped :

Here is my configure command which works fine without “—enable-perl” :

./configure --prefix=/usr/app/LDAP/binaries/openldap-2.5.7/ --sysconfdir=/usr/app/LDAP/binaries/openldap-2.5.7 --mandir=/usr/local/share/man --enable-modules --enable-ldap --enable-dynlist --enable-ppolicy --enable-unique --with-gnu-ld --enable-refint --with-tls --enable-dynamic --enable-valsort --enable-rwm --enable-perl

Any idea of what's the issue ?

Looks like you didn't link against libperl.

Hello Howard,

I did check compilation steps following your advice and I found the library "libperl.so" was not in the compliation argument of libbackends.a. After a few tries how to provide it (way of & format), I found it was enough to set following variable as : LDFLAGS=/usr/lib64/libperl.so before to do the "configure".

Usually you would use LIBS instead of LDFLAGS for this, but whatever works for you.

By doing this, I was able to compile 2.5.7 version with back-perl module enabled :-)

Thx for help.

Brgds, Jean-Luc.
