Question

I’m very new to autotools and it looks like I have a problem with libtool – it doesn’t build a shared library and makes a static one instead…

This is how my configure.ac looks like:

AC_PREREQ([2.67])
AC_INIT([helloworld], [1.0], [...])
AM_INIT_AUTOMAKE([foreign])
LT_INIT

# Checks for programs.
AC_PROG_CXX
AC_PROG_LIBTOOL

# Checks for header files.
AC_CHECK_HEADERS([alloca.h inttypes.h stdint.h])

AC_CONFIG_FILES([Makefile])
AC_OUTPUT

and Makefile.am:

noinst_LTLIBRARIES=helloworld.la

helloworld_la_CXXFLAGS=-w -DLINUX ...
helloworld_la_LDFLAGS=-avoid-version -module -shared -export-dynamic

# List of source files
helloworld_la_SOURCES=helloworld.cpp ...

Is there something wrong here?

Thanks for any help.

Answer 1

I believe you want

lib_LTLIBRARIES = helloworld.la

Using noinst instructs libtool to build a convenience library, and those
are not typically shared.
