Some of the files in my convenience libraries have static initializers. By default, the linker discards these symbols because they are not referenced. I am trying to figure out how to keep them in an automake-driven build.
Mailing list threads I have seen on the Internet, plus the "libtool" script code (as of version 2.2.6b), indicate that convenience libraries should be linked with -Wl,--whole-archive (or the equivalent). I do not see that here. In a reduced test case, my Makefile.am looks like this: ACLOCAL_AMFLAGS = -I m4 AUTOMAKE_OPTIONS = foreign noinst_LTLIBRARIES = libsubdir.la libsubdir_la_LDFLAGS = -static libsubdir_la_SOURCES = subdir/item.cpp noinst_PROGRAMS = test test_SOURCES = test.cpp test_LDADD = libsubdir.la And the final link stage looks like this: /bin/sh ./libtool --tag=CXX --mode=link g++ -g -O2 -o test test.o libsubdir.la libtool: link: g++ -g -O2 -o test test.o ./.libs/libsubdir.a .. and the static initialization code in subdir/item.cpp is not called. What am I overlooking (or doing wrong)? (For completeness, the reduced configure.ac looks like this: AC_INIT([lttest], [1.0]) AC_CONFIG_MACRO_DIR([m4]) AC_CONFIG_SRCDIR([test.cpp]) AM_INIT_AUTOMAKE([-Wall -Werror]) LT_INIT([static disable-shared]) AC_PROG_CXX AC_CONFIG_FILES([Makefile]) AC_OUTPUT test.cpp has an empty main() and subdir/item.cpp contains a static instance of a class that prints "Hello world" in its constructor.)
