I have 2 modules, each with their own _init and _fini functions. My
Makefile.am file is as follows:
lib_LTLIBRARIES = dns.la select.la
dns_la_SOURCES = dns.c
dns_la_LDFLAGS = -module $(LDFLAGS)
select_la_SOURCES = select.c
select_la_LDFLAGS = -module $(LDFLAGS)
After running automake, autoconf, etc, I try to compile, and I receive
this, minus start/end wrappers:
****************** START ******************
/bin/bash ../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I.
-I../../include -g -O2 -c -o dns.lo `test -f 'dns.c' || echo
'./'`dns.c
mkdir .libs
gcc -DHAVE_CONFIG_H -I. -I. -I../../include -g -O2 -c dns.c -fPIC
-DPIC -o .libs/dns.lo
gcc -DHAVE_CONFIG_H -I. -I. -I../../include -g -O2 -c dns.c -o dns.o
>/dev/null 2>&1
mv -f .libs/dns.lo dns.lo
/bin/bash ../../libtool --mode=link gcc -g -O2 -o dns.la -rpath
/usr/local/lib -module dns.lo
rm -fr .libs/dns.la .libs/dns.* .libs/dns.*
gcc -shared dns.lo -Wl,-soname -Wl,dns.so.0 -o .libs/dns.so.0
dns.lo: In function `_init':
/services/services/src/modules/dns.c:40: multiple definition of `_init'
/usr/lib/crti.o(.init+0x0): first defined here
dns.lo: In function `_fini':
/services/services/src/modules/dns.c(.text+0x88): multiple definition
of `_fini'
/usr/lib/crti.o(.fini+0x0): first defined here
*** Error code 1
****************** END ******************
What I need help with is compiling the so modules. I have no idea what
crti.o is. I've no trouble compiling when doing so manually, but I
compile without linking, and call ld separately. I would rather use
the automake suite, however, than writing the entire Makefiles on my
own. Thanks in advance for any help provided.
