There are problems configuring LDAP and Squid 2.5 Stable 12. Environment: ------------ Hardware: COMPAQ Professional Workstation XP1000 OS: Tru64 V5.1A (OSF1 GOAW25 V5.1 1885 alpha) configure step runs without any problems: ./configure --enable-auth="ntlm,basic" \ --enable-external-acl-helpers="winbind_group,ldap_group" \ --enable-basic-auth-helpers="winbind" \ --enable-ntlm-auth-helpers="winbind" \ --prefix=/usr/local/squid Now "make all" leads to following error: Making all in ldap_group source='squid_ldap_group.c' object='squid_ldap_group.o' libtool=no depfile='.de ps/squid_ldap_group.Po' tmpdepfile='.deps/squid_ldap_group.TPo' depmode=gcc3 /b in/sh ../../../cfgaux/depcomp gcc -DHAVE_CONFIG_H -I. -I. -I../../../include -g -O2 -Wall -c `test -f squid_ldap_group.c || echo './'`squid_ldap_group.c squid_ldap_group.c:40:18: lber.h: No such file or directory squid_ldap_group.c:41:18: ldap.h: No such file or directory Therefore I copied missing files (and some others) from /usr/internet/openldap/include to /usr/local/squid-2.5.STABLE12/helpers/external_acl/ldap_group After that compilation of squid_ldap_group.c worked fine. But I get another error message: /usr/bin/ld: Can't locate file for: -lldap collect2: ld returned 1 exit status *** Exit 1 What goes wrong? Werner Rost
