Subject: [patch] fix ldap capacities detection
Date: Wed, 02 Jul 2008 13:35:38 +0200 [thread overview]
Message-ID: <486B680A.8050005@inria.fr> (raw)

When using -Wl,-a-s-needed linker flags (which is becoming the standard
in most linux distributions), compilation will fail if -lldap is passed
before the test file in gcc command:
[guillomovitch@n2 autofs]$ gcc -o conftest -O2 -g -pipe
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -fstack-protector-all -fomit-frame-pointer
-march=i586 -mtune=generic -fasynchronous-unwind-tables
-Wl,--as-needed -Wl,--no-undefined -lldap conftest.c
/home/guillomovitch/tmp/ccsbs3BH.o: In function `main':
/home/guillomovitch/cooker/autofs/BUILD/autofs-5.0.3/conftest.c:45:
undefined reference to `ldap_create_page_control'
The proper solution is to pass -lldap trough $LIBS variable instead of
$LDFLAGS.
