Hi List!
I'm in trouble building a huge shared lib from a long list of
convenience libs. Using Linux, everything's fine, the current
troublemaker is a "Darwin Kernel Version 8.7.0" machine.
Compiling all libs works without problems, a typical Makefile.am looks
like:
noinst_LTLIBRARIES = liboptimize.la
liboptimize_la_CXXFLAGS = @GRALAB_CPPFLAGS@
liboptimize_la_LIBADD = @GRALAB_LIBS@
liboptimize_la_LDFLAGS = @RG_LA_LDFLAGS@
liboptimize_la_SOURCES = \
boolexpr.cpp [...]
liboptimize_ladir = $(includedir)/re-group/greql/optimize
liboptimize_la_HEADERS = \
optimize.h \ [...]
The "one lib" (libgreql) uses the following Makefile.am:
libgreqldir = $(libdir)/re-group
libgreql_LTLIBRARIES = libgreql.la
libgreql_la_SOURCES = greql.cpp
libgreql_la_LDFLAGS = @RG_LA_LDFLAGS@
libgreql_la_LIBADD = \
../pdlst/libpdlst.la \
../tsystem/libtsystem.la \
../optimize/liboptimize.la \
../regexp/libregexp.la \
../error/liberror.la \
../repre/librepre.la \
../path/libpath.la \
../cvalue/libcvalue.la \
../pathinterface/libpathinterface.la \
../coreval/libcoreval.la \
../eval/libeval.la \
../funbig/libfunbig.la \
../inline/libinline.la \
../queryresult/libqueryresult.la \
../schema/libschema.la \
../queryevaluator/libqueryevaluator.la \
@XERCESC_LIBS@
libgreql_adir = $(includedir)/re-group/greql
libgreql_a_HEADERS = greql.h greqlversion.h
Libtool then goes trying to put things together; the call is:
/bin/sh ../libtool --mode=link g++ -g -O2
-L/Users/eyerq/local/lib/re-group -o libgreql.la
-rpath /Users/eyerq/local/lib/re-group -version-info 1:0:0
greql.lo ../pdlst/libpdlst.la ../tsystem/libtsystem.la
../optimize/liboptimize.la ../regexp/libregexp.la ../error/liberror.la
../repre/librepre.la ../path/libpath.la ../cvalue/libcvalue.la
../pathinterface/libpathinterface.la ../coreval/libcoreval.la
../eval/libeval.la ../funbig/libfunbig.la ../inline/libinline.la
../queryresult/libqueryresult.la ../schema/libschema.la
../queryevaluator/libqueryevaluator.la -L/Users/eyerq/local/lib -lxerces-c
-lrgutil
g++ -dynamiclib -single_module -flat_namespace -undefined suppress
-o .libs/libgreql.1.dylib .libs/greql.o
-all_load ../pdlst/.libs/libpdlst.a ../tsystem/.libs/libtsystem.a
../optimize/.libs/liboptimize.a ../regexp/.libs/libregexp.a
../error/.libs/liberror.a ../repre/.libs/librepre.a ../path/.libs/libpath.a
../cvalue/.libs/libcvalue.a ../pathinterface/.libs/libpathinterface.a
../coreval/.libs/libcoreval.a ../eval/.libs/libeval.a
../funbig/.libs/libfunbig.a ../inline/.libs/libinline.a
../queryresult/.libs/libqueryresult.a ../schema/.libs/libschema.a
../queryevaluator/.libs/libqueryevaluator.a -L/Users/eyerq/local/lib/re-group
/Users/eyerq/local/lib/re-group/libgralab.5.0.0.dylib -L/Users/eyerq/local/lib
-lxerces-c /Users/eyerq/local/lib/re-group/librgutil.1.0.0.dylib -install_name
/Users/eyerq/local/lib/re-group/libgreql.1.dylib -compatibility_version 2
-current_version 2.0
This fails with a long list of "multiple definitions of symbol xyz"
which seem to all come from one lib: liboptimize.
I am willing to provide as much information as needed as I'm on a loss
here; maybe someone has already seen some mistakes of mine or has an
idea?
