Further search in the excellent modperl guide by Stas Bekman at http://perl.apache.org/guide/install.html#Undefined_reference_to_PL_perl_ suggested a clue for this problem: > This happens when you have Perl built statically linked, with no shared libperl.a. Build a dynamically linked Perl (with libperl.a) and the problem will disappear. Don't I actually have dynalink support in my perl if perl -V says Linker and Libraries: ld='cc', ldflags =' -L/usr/local/lib -L/opt/local/lib' libpth=/usr/local/lib /opt/local/lib /lib /usr/lib /usr/ccs/lib libs=-lsocket -lnsl -ldl -lm -lc -lcrypt libc=/lib/libc.so, so=so useshrplib=false, libperl=libperl.a Dynamic Linking: dlsrc=dl_dlopen.xs, dlext=so, d_dlsymun=undef, ccdlflags=' ' cccdlflags='-Kpic', lddlflags='-G -L/usr/local/lib -L/opt/local/lib' and also the libperl.a is there: /usr/local/lib/perl5/sun4-solaris/5.00404/CORE/libperl.a And, also, to make it 100% sure, I ensured that /usr/local/lib/perl5/sun4-solaris/5.00404/CORE/ is on the httpd's LD_LIBRARY_PATH :-( Vassilii -----Original Message----- From: Khachaturov, Vassilii Sent: Thursday, October 19, 2000 12:29 PM To: '[EMAIL PROTECTED]' Subject: installing mod_perl-1.24_01/apache_1.3.14/perl 5.004_04/solaris 5 .6 Hi! I have been trying to install the <subj> combination for a couple of hours with no luck. After looking up Ken's archive, I decided to turn to the list for the help. I have gone exactly through the steps suggested in the apache readme file: ... $ perl Makefile.PL APACHE_SRC=../apache_1.3.14/src \ DO_HTTPD=1 USE_APACI=1 \ EVERYTHING=1 (this reports no problems or versioning hints, and successfully completes) $ make This fails at httpd build stage, in the following way: [see http://forum.swarthmore.edu/epigone/modperl/brelfrermlal ]
