syslog-ng 2.1.4 needs explicit globals.o to create executable

[denis.laplante@…]

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.

patch to Makefile.in to force load of globals.o

Many thanks for the Makefile patch. The logreader patch was not necessary since it made it into the source by now.

Also passing the Makefile patch upstream so there will hopefully be a fix in the source for that on OS X also.
