#19577: syslog-ng 2.1.4 needs explicit globals.o to create executable -----------------------------------+---------------------------------------- Reporter: denis.laplante@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.7.1 Keywords: xCode | Port: syslog-ng -----------------------------------+---------------------------------------- I have a workaround for what seems like a xCode bug. syslog-ng version 2.1.4 fails in compilation with MacPorts; specifically "ld" while creating executable fails to load "globals.o" from libsyslog- ng.a. Error message:

/usr/bin/gcc-4.0 -O2 -Wall -L/opt/local/lib -o syslog-ng main.o libsyslog-ng.a \ -lresolv -lfl -L/opt/local/lib -lglib-2.0 -lintl -liconv -L/opt/local/lib \ -levtlog -lnet -lwrap Undefined symbols: "_configuration", referenced from: _configuration$non_lazy_ptr in libsyslog-ng.a(cfg.o) _configuration$non_lazy_ptr in libsyslog-ng.a(cfg-grammar.o) ld: symbol(s) not found

The workaround is to append "globals.o" to command "gcc ... -o syslog-ng ... -lwrap". I tried (no success) appending libsyslog-ng.a , and upgrading Apple xCode compilation package from 3.1.1 to 3.1.2 The object file is in fact present in the archive and contains "_configuration".

$ nm libsyslog-ng.a libsyslog-ng.a(misc.o): [...] libsyslog-ng.a(cfg.o): [...] U _configuration [...] libsyslog-ng.a(cfg-grammar.o): [...] U _configuration [...] libsyslog-ng.a(globals.o): 00000004 D _allow_severity 00000004 C _configuration 00000000 D _deny_severity 00000004 C _server_mode

One red herring was the error message

ranlib: file: libsyslog-ng.a(afsql.o) has no symbols Deleting afsql.o from libsyslog-ng.a and re-running ranlib (no errors) did not help. Editing Makefile to remove afsql.o did not help.

I've attached patch-Makefile.in.diff to explicitly add globals.o, which fixes this weird problem. Another problem I had after installing the binary produced with explicit "globals.o": the "file" source driver goes into a tight loop instead of sleeping between read attempts. See bugzilla.balabit.com ticket 43. I have attached patch-src-logreader.c.diff for convenience, since version 2.1.5 does not yet appear on download site. Solaris had no trouble with libsyslog-ng.a, even though it also uses ranlib. -- Ticket URL: <http://trac.macports.org/ticket/19577> MacPorts <http://www.macports.org/> Ports system for Mac OS
